What is avian malaria and what are the primary genera of parasites responsible for it?

Avian malaria is a parasitic disease that affects birds. It is caused by parasite species belonging to the genera *Plasmodium* and *Hemoproteus*. These parasites are protozoa from the phylum Apicomplexa and the class Haemosporidia.

How is avian malaria transmitted to birds, and what types of vectors are involved?

Avian malaria is transmitted through a dipteran vector, which is an insect belonging to the order Diptera. Specifically, *Plasmodium* parasites are transmitted by mosquitoes, while *Hemoproteus* parasites are transmitted by biting midges.

What is the range of impacts avian malaria can have on bird populations?

The effects of avian malaria on bird hosts are highly variable. Cases can range from being asymptomatic, meaning the bird shows no signs of illness, to causing drastic population declines, as observed in the Hawaiian honeycreepers.

Why was avian malaria a subject of study for researchers like Dr. Ross?

Avian malaria was studied by researchers like Dr. Ross because the diversity of avian malaria parasites is vast, with estimates suggesting there are as many parasite species as host species. As research on human malaria parasites became difficult, Dr. Ross found avian malaria parasites to be a more accessible model for his studies.

What is the most notable species of Plasmodium that causes avian malaria, and where is it found?

The most notable species causing avian malaria is *Plasmodium relictum*. This protist infects birds globally, with the exception of Antarctica.

Why are captive penguins in non-native environments particularly susceptible to avian malaria?

Captive penguins in non-native environments are especially sensitive to infection by *Plasmodium relictum* because they have not coevolved with these protozoa. This lack of evolutionary resistance often leads to a severe form of the disease, with the most common presentation being acute death.

Besides *Plasmodium relictum*, what other *Plasmodium* species infect birds, and when are they significant?

Other species of *Plasmodium* that infect birds include *Plasmodium anasum* and *Plasmodium gallinaceum*. While generally of lesser importance, they can occasionally pose a threat to the poultry industry.

What are the geographical distribution patterns of avian malaria?

Avian malaria is found worldwide. However, there are important exceptions, and it is notably absent from Antarctica. In areas where it is newly introduced, like Hawaii, it can be devastating to naive bird populations.

How do *Plasmodium* and *Haemoproteus* parasites reproduce within their hosts and vectors?

These protozoan parasites reproduce asexually within their bird hosts. They also undergo both asexual and sexual reproduction within their respective insect vectors, which include mosquitoes, biting midges, and louse flies.

What types of insects serve as vectors for avian malaria parasites?

The insect vectors for avian malaria parasites include mosquitoes (family Culicidae) for *Plasmodium* species, biting midges (family Ceratopogonidae) for *Hemoproteus* and some *Plasmodium* species, and louse flies (family Hippoboscidae) which can also transmit *Haemoproteus*.

What factors contribute to the complexity of studying avian malaria parasites?

The study of avian malaria parasites is complex due to the large number of parasite lineages, their wide range of potential host species, and their capacity for host switching. Evolutionary relationships between hosts and parasites further add to this complexity, suggesting extensive sampling is needed to understand disease transmission.

How can migratory birds influence the spread and prevalence of avian malaria?

Migratory birds can facilitate the dispersal of avian malaria parasites. This movement increases variation in prevalence patterns across different regions and can alter the processes of host-parasite adaptation.

What factors are being investigated to understand host susceptibility to avian malaria?

Researchers are investigating various host traits to understand susceptibility to avian malaria. These include nesting and foraging height, sexual dimorphism, and incubation period length. However, the overall effects of the disease in wild populations remain poorly understood.

What did a 2015 study in Malawi reveal about malaria infections in birds?

A 2015 study analyzing blood samples from Malawian bird fauna found that nearly 80% of the birds were infected with either malaria or closely related alveolates. This highlights the widespread presence of these parasites in bird populations.

According to the Malawi study, which types of birds were more likely to be infected with *Plasmodium* versus midge-borne parasites?

In the Malawi study, closed-cup nesters, such as weavers and *Cisticola* species, were found to be more likely to be infected with *Plasmodium* parasites compared to midge-borne parasites like *Haemoproteus* and *Leucocytozoon*.

What has historically been the basis for classifying avian malaria parasite species?

Historically, avian malaria parasites were classified based on a limited set of morphological characteristics and their ability to infect specific bird species. This traditional approach has led to considerable disagreement regarding species diversity and evolutionary relationships.

How has molecular data influenced the classification of malaria parasites?

Molecular data has shifted the classification approach towards a phylogenetic definition of parasite lineages. This method relies on sequence divergence, particularly in genes like cytochrome b, and the range of hosts a parasite can infect, offering a more refined understanding than morphology alone.

What is the purpose of the MalAvi database?

The MalAvi database was created to serve as a public repository for sequences of avian malaria parasites and related haemosporidians. Its goal is to encourage the sharing of genetic sequence data, particularly from the cytochrome b gene, to aid in understanding the vast diversity of these parasites.

What sequence divergence value is used as a cutoff to distinguish between different parasite lineages in molecular studies?

In the absence of other developed genetic markers for avian malaria parasites, a sequence divergence of approximately 1.2% to 4% in specific genes, such as cytochrome b, has been determined as a cutoff value to differentiate between distinct parasite lineages.

What do molecular studies suggest about the phylogenetic relationships between *Plasmodium* species infecting birds/reptiles and mammals?

Molecular data suggests that *Plasmodium* species infecting birds and squamate reptiles belong to one distinct clade, while those infecting mammals form a separate clade. This indicates a divergence in the evolutionary paths of these parasites across different vertebrate groups.

How has *Haemoproteus* traditionally been classified, and what do molecular data suggest?

Traditionally, *Haemoproteus* was classified based on the type of insect vector transmitting it. Molecular data supports this, suggesting that one clade is transmitted by hippoboscid flies to columbiform birds, while another group, potentially reclassified as *Parahaemoproteous*, is transmitted by biting midges to other avian families.

Which *Plasmodium* species is most commonly associated with avian malaria, and what genetic marker is used to study its epidemiology?

The *Plasmodium* species most commonly associated with avian malaria is *Plasmodium relictum*. To study its epidemiology and geographical distribution, analyses often focus on genetic variation in the nuclear gene MSP1 (merozoite surface protein 1).

What have genetic analyses of *Plasmodium relictum* revealed about its geographical distribution?

Genetic variation analyses of *Plasmodium relictum* across large geographical scales have revealed significant differences between lineages found in the New World and the Old World. This suggests that the parasite may have been introduced to avian populations multiple times in different regions.

What do variations between European and African *Plasmodium relictum* lineages indicate?

Considerable genetic variation found between European and African lineages of *Plasmodium relictum* suggests different patterns of transmission exist between temperate and tropical bird populations. Understanding these patterns is crucial for predicting disease spread.

How well are parasite-vector relationships understood in avian malaria research?

Compared to the understanding of parasite-avian interactions, the relationships between avian malaria parasites and their specific vectors are relatively less explored. While databases like MalAvi list known vectors, the knowledge is not yet complete.

What is the primary mosquito vector for avian malaria in Hawaii, and when was it introduced?

The primary mosquito vector for avian malaria in Hawaii is *Culex quinquefasciatus*. This mosquito species was introduced to the Hawaiian Islands in 1826.

What has been the ecological impact of *Culex quinquefasciatus* mosquitoes and avian malaria in Hawaii?

Since its introduction, the *Culex quinquefasciatus* mosquito, along with avian malaria and avipoxvirus, has devastated native bird populations in Hawaii, leading to numerous extinctions. Hawaii has experienced more bird extinctions than any other place globally, with ten unique species disappearing since the 1980s.

How do cold temperatures affect the distribution of the *Culex quinquefasciatus* mosquito in Hawaii?

Cold temperatures limit the distribution of *Culex quinquefasciatus* mosquitoes to lower elevations, generally below 5,000 feet (1,500 meters), as these temperatures prevent larval development. However, there is concern that these mosquitoes may be slowly adapting to higher elevations.

What is the concern regarding the potential upward expansion of mosquito range in Hawaii?

If *Culex quinquefasciatus* mosquitoes continue to expand their range upwards to higher elevations, most remaining native Hawaiian land birds could become at risk of extinction. This is particularly concerning as many islands have maximum elevations below the current mosquito limit.

Who was Sir Ronald Ross, and what was his significant contribution to malaria research?

Sir Ronald Ross was a physician born in India who became a pioneer in malaria research. He is most famous for his discovery that mosquitoes transmit malaria parasites to humans, a finding for which he was awarded the Nobel Prize in Medicine in 1902. He later used avian malaria as a model to further understand this transmission.

What was Ronald Ross's landmark discovery in 1897 regarding malaria transmission?

In 1897, Ronald Ross discovered the malaria parasite within the stomach tissue of an anopheline mosquito that had fed on a malaria-infected patient. This finding conclusively proved the role of *Anopheles* mosquitoes in the transmission of malaria parasites to humans.

How did Ronald Ross use avian malaria in his research after his discovery?

After demonstrating mosquito transmission of human malaria, Ross used avian malaria as a more convenient experimental model. In 1898, he successfully showed that mosquitoes could act as intermediate hosts for bird malaria, demonstrating parasite development within the mosquito and their subsequent transmission to other birds.

What are sporozoites, and how do they initiate the avian malaria infection cycle?

Sporozoites are immature forms of the malaria parasite. The infection cycle begins when these sporozoites, carried in the saliva of infected female mosquitoes, are transmitted to a bird through a bite. They may enter the bloodstream directly or penetrate the skin.

What happens to the malaria parasites after sporozoites enter the bird's tissues?

After entering the bird, sporozoites mature into merozoites within fibroblasts and macrophages. These merozoites are then released into the bloodstream and travel to organs like the brain, liver, spleen, kidney, and lungs, where they infect macrophages.

How does asexual reproduction of the parasite lead to the acute phase of infection?

Inside the bird's organs, the parasites undergo asexual reproduction, creating numerous copies of themselves. These new merozoites infect red blood cells, where they grow and reproduce further. Eventually, the infected red blood cells burst open, releasing more parasites and triggering the acute phase of the disease.

What are the primary symptoms observed during the acute phase of avian malaria?

The acute phase of avian malaria in susceptible birds is primarily characterized by anemia, resulting from the destruction of red blood cells. This is accompanied by general symptoms of illness, including weakness, depression, and loss of appetite. In severe cases, the infection can lead to coma and death.

How does *Plasmodium relictum* cause anemia in infected birds?

*Plasmodium relictum* reproduces within the bird's red blood cells. As the parasite load increases, a significant number of red blood cells are destroyed, leading to a condition known as anemia. Anemia occurs when the body lacks enough healthy red blood cells to carry adequate oxygen to tissues.

Which group of birds is most commonly affected by avian malaria, and what are some examples?

Avian malaria primarily affects passerines, which are perching birds. In Hawaii, this includes many native species like the Hawaiian honeycreepers and the Hawaiian crow. Susceptibility varies greatly between species.

How does susceptibility to avian malaria differ between native and introduced birds in Hawaii?

Native Hawaiian birds are generally more susceptible to avian malaria than introduced bird species. Consequently, they exhibit a higher mortality rate from the disease, which has severe implications for the conservation of native avian fauna.

What has been the impact of *P. relictum* on bird populations in Hawaii?

*Plasmodium relictum* is blamed for the restriction of geographical ranges and the extinction of numerous bird species in Hawaii. This impact is most pronounced in forest birds inhabiting low-land forest habitats, where the mosquito vector is most prevalent.

What factors have been found to influence *Plasmodium* infections in birds in California urban areas?

Recent studies in California have indicated that *Plasmodium* infections in birds, such as the Dark-eyed Junco, are more strongly influenced by rainfall patterns than by urbanization itself. Conversely, infections by more specialized parasites like *Haemoproteus* tend to decrease in highly urbanized environments.

How has the overall incidence of avian malaria changed globally in recent decades?

The incidence of avian malaria has nearly tripled globally over the past 70 years. This increase is often linked to rising global temperatures, which can expand the range and activity of vector mosquitoes.

What are the observed trends in malaria infection rates for specific European bird species?

Notable increases in malaria infection rates have been observed in several European species. For instance, house sparrows (*Passer domesticus*) saw infections rise from under 10% to nearly 30%, great tits (*Parus major*) from 3% to 15% since 1995, and Eurasian blackcaps (*Sylvia atricapilla*), once unaffected, showed 4% infection rates by 1999. Tawny owls in the UK experienced a dramatic rise from 2-3% to 60%.

What do studies suggest about the relative importance of speciation versus host switching in avian haemosporidians?

Studies suggest that host switching is a more common phenomenon among avian haemosporidians, including those causing avian malaria, than speciation events. Adaptation to locally available host populations appears to play a secondary role compared to the ability to switch hosts.

What is the primary strategy for controlling avian malaria?

The main approach to controlling avian malaria is through the management and control of mosquito populations, as they are the vectors responsible for transmitting the disease. Reducing mosquito numbers directly reduces the potential for disease spread.

How does managing feral pig populations contribute to mosquito control in areas like Hawaii?

Managing feral pig populations can help control mosquitoes because the wallows created by pigs, along with water collected in native fern logs, provide ideal breeding grounds for mosquitoes. Removing pigs reduces these sources of standing water where mosquito larvae develop.

What measures can be taken around human dwellings to reduce mosquito breeding sites?

Around houses, reducing the number of containers that can collect water is an effective measure to decrease potential breeding sites for mosquitoes. This includes emptying water from plant pots, old tires, and other receptacles.

Have mosquito control efforts in Hawaii been entirely successful in eliminating the threat of avian malaria?

No, attempts to control mosquitoes in Hawaii through methods like reducing larval habitats and using larvicides have not completely eliminated the threat of avian malaria. The disease continues to pose a significant risk to native bird populations.

What is a potential strategy involving breeding birds to combat avian malaria?

One strategy involves identifying and breeding birds that are naturally resistant to avian malaria. Collecting eggs from these resistant birds and raising young for re-introduction into affected areas could help bolster the population's overall resistance and give the species a better chance of survival.

What novel genetic technology has been proposed for mosquito control in Hawaii?

The use of CRISPR gene editing technology has been suggested as a potential method for extirpating invasive mosquito populations in Hawaii, thereby controlling the spread of avian malaria.

Overview

Parasitic Disease of Birds

Avian malaria is a parasitic disease affecting birds, caused by protozoan species within the genera Plasmodium and Haemoproteus. These parasites belong to the phylum Apicomplexa and the class Haemosporidia. The disease is transmitted by dipteran vectors: mosquitoes for Plasmodium and biting midges for Haemoproteus. The clinical presentation and impact vary widely, ranging from asymptomatic infections to severe population declines, notably observed in the Hawaiian honeycreepers.

Global Distribution and Complexity

The diversity of avian malaria parasites is immense, with estimates suggesting a number of parasite species comparable to the number of bird species. Historically, avian malaria served as a crucial model for studying human malaria parasites, particularly by researchers like Dr. Ross. Complex evolutionary processes, including co-speciation and host switching, have contributed to the broad host range and widespread global presence of these parasites, with Antarctica being the only continent free of avian malaria.

Research Significance

The study of avian malaria parasites has provided invaluable insights into host-parasite co-evolution and disease transmission dynamics. Molecular techniques, particularly the analysis of the cytochrome b gene, have become essential for classifying parasite lineages and understanding their phylogenetic relationships. Databases like MalAvi facilitate the sharing of sequence data, aiding researchers in mapping the complex web of avian haemosporidian diversity.

Cause

Primary Pathogens

The most frequently implicated parasite in avian malaria is Plasmodium relictum, a protist found globally, except in Antarctica. While many bird species have coevolved with these parasites, non-native populations, such as captive penguins, can be highly susceptible, sometimes leading to acute mortality. Other Plasmodium species, like P. anasum and P. gallinaceum, also infect birds, though they are generally of lesser significance except in specific contexts like the poultry industry.

Impact on Naive Populations

In regions where avian malaria is newly introduced, such as the Hawaiian Islands, the disease can have devastating effects on bird populations that lack evolved resistance. This is particularly true for species like the Mohoidae family. The absence of co-evolutionary history means these birds are highly vulnerable, leading to drastic population declines and contributing to numerous extinctions.

Parasite Species

Genera and Vectors

Avian malaria is caused by protozoa in the genera Plasmodium and Haemoproteus. These parasites undergo both asexual reproduction within avian hosts and sexual/asexual cycles within insect vectors. Known vectors include mosquitoes (family Culicidae), biting midges (family Ceratopogonidae), and louse flies (family Hippoboscidae). The sheer diversity of parasite lineages, coupled with their capacity for host switching, complicates the study of their evolutionary history and transmission patterns.

Evolutionary Dynamics

The classification of avian malaria parasites is complex, with traditional morphological characteristics often yielding ambiguous results. Molecular data, particularly DNA sequencing, has led to a phylogenetic approach, defining lineages based on genetic divergence. Extensive host switching and parasite sharing among different avian species are common, suggesting that adaptation to locally available hosts plays a significant role alongside co-speciation events in shaping parasite distribution.

Prevalence and Host Traits

Studies, such as one involving bird fauna in Malawi, indicate high infection rates with malaria or related alveolates. Certain host traits, like nesting behavior (e.g., closed-cup nesters), appear correlated with higher infection rates by specific parasite types. The dispersal capabilities of migratory birds further influence prevalence patterns and host-parasite adaptation processes across geographical scales.

Vector

Primary Mosquito Vector

In Hawaii, the primary vector for avian malaria is the mosquito Culex quinquefasciatus, introduced in 1826. This vector, along with the avipoxvirus, has been implicated in numerous extinctions and severe population declines of native Hawaiian birds. The mosquitoes are typically found at lower elevations, below 1,500 meters, due to temperature constraints on larval development. However, there is evidence suggesting their range may be expanding to higher altitudes, posing an increased risk to remaining endemic species.

Other Vectors and Limited Knowledge

While mosquitoes are the most prominent vectors, other dipteran insects like biting midges (Ceratopogonidae) and louse flies (Hippoboscidae) can also transmit avian malaria parasites. Despite the known vectors, the specific parasite-vector relationships remain relatively under-explored compared to the host-parasite interactions. The MalAvi database lists known vectors, but the list is considered incomplete.

Cycle

Initial Infection

The infection cycle begins when an infected female mosquito, carrying sporozoites in its saliva, bites a bird. These sporozoites may directly enter the bloodstream or penetrate the skin, invading fibroblasts and macrophages. Within these cells, they mature into merozoites.

Asexual Reproduction and Red Blood Cells

After approximately 36 to 48 hours, merozoites are released and travel to various organs, including the brain, liver, spleen, kidneys, and lungs. Here, they initiate asexual reproduction. The subsequent generations of merozoites infect red blood cells, where they multiply further, eventually causing the cells to rupture. This process leads to the acute phase of the disease.

Acute Phase Symptoms

The acute phase is characterized by anemia due to the loss of red blood cells. Affected birds exhibit symptoms such as weakness, depression, and loss of appetite. In severe cases, birds may become comatose and succumb to the infection. Susceptibility varies significantly among species; for instance, the ʻIʻiwi is highly susceptible, while the ʻApapane is comparatively more resistant.

Epidemiology

Increasing Incidence

The incidence of avian malaria has shown a notable increase, nearly tripling over the past 70 years. This trend is linked to rising global temperatures, which potentially expand suitable habitats for vectors. Species like house sparrows, great tits, and Eurasian blackcaps have experienced significant increases in infection rates. For example, malaria infection in house sparrows rose from less than 10% pre-1990 to nearly 30% in recent years.

Climate Change Influence

Climate change is recognized as a significant driver of increasing avian malaria risk. Warmer temperatures can facilitate vector survival and reproduction, potentially extending their range and the transmission season. Studies in California suggest rainfall patterns influence infection risk more than urbanization for some species, while Haemoproteus infections decrease in highly urbanized areas.

Impact on Island Ecosystems

Avian malaria poses a severe threat to island ecosystems with naive bird populations. In Hawaii, the introduction of Culex quinquefasciatus mosquitoes has led to widespread range restrictions and extinctions of native forest birds, particularly those inhabiting lower elevations. The potential upward expansion of mosquito ranges threatens the remaining populations, highlighting the vulnerability of isolated fauna.

Research

Historical Context: Ronald Ross

Sir Ronald Ross's pioneering work in the late 19th century laid the foundation for understanding malaria transmission. His research, initially focused on human malaria, utilized avian malaria models. In 1897, he proved the role of Anopheles mosquitoes in human malaria transmission. Subsequently, in 1898, he demonstrated that mosquitoes could serve as intermediate hosts for bird malaria parasites, observing their development and migration to salivary glands, enabling transmission to other birds. Ross was awarded the Nobel Prize in Medicine in 1902 for these discoveries.

Modern Methodologies

Contemporary research employs molecular tools, such as analyzing the mitochondrial cytochrome b gene, to classify parasite lineages and reconstruct phylogenies. This approach has revealed cryptic speciation and highlighted the prevalence of host switching events. The MalAvi database serves as a crucial resource for cataloging avian haemosporidian sequences, facilitating global comparative studies and advancing our understanding of parasite diversity and evolution.

Phylogeography and Adaptation

Phylogeographic studies using genetic markers like MSP1 (merozoite surface protein 1) have identified significant genetic differences between parasite lineages in the New and Old Worlds, suggesting distinct introduction events. Variation between European and African lineages further indicates differing transmission patterns in temperate versus tropical populations. Research also explores the balance between co-speciation and host switching, with evidence suggesting host switching is a common phenomenon in avian haemosporidians.

Control

Vector Management

The primary strategy for controlling avian malaria involves managing mosquito populations. In Hawaii, efforts include removing potential breeding sites like feral pig wallows and standing water containers. However, traditional methods such as larval habitat reduction and larvicide use have proven insufficient to eliminate the threat posed by vectors like Culex quinquefasciatus.

Conservation and Adaptation

Conservation efforts focus on preserving susceptible bird populations and their habitats. Reforestation of high-elevation areas can provide refuge zones. There is evidence of evolving resistance in some native Hawaiian species, such as the ʻAmakihi. Supporting these species and potentially reintroducing captive-bred birds may help populations adapt over time before climate change or further vector range expansion exacerbates the problem.

Innovative Approaches

Advanced techniques, such as using CRISPR gene editing to potentially control mosquito populations, have been proposed as future control strategies. Understanding the complex interplay between parasites, vectors, hosts, and environmental factors remains critical for developing effective, long-term management plans to protect avian biodiversity from the impacts of malaria.
