Hepatozoon is a tick-associated protozoan parasite, transmitted not by tick bite but by ingestion of infected ticks, that commonly infects wild felids including lions. This overview surveys the biolog…

Many of the most important felid diseases, from distemper to leukemia virus to Toxoplasma, originate at the interface of domestic animals, wildlife and people, making them quintessential One Health pr…

Following the Bronx Zoo tigers, SARS-CoV-2 infections were confirmed in big cats at zoos and sanctuaries across multiple countries, including additional tigers, lions, snow leopards, pumas and others.…

Sarcocystis parasites cycle between predator definitive hosts and prey intermediate hosts, with felids shedding infective stages after eating cysts in muscle. This overview surveys the role of wild ca…

Spirometra tapeworms use felids and other carnivores as definitive hosts, while their larval stages, known as spargana, infect a wide range of intermediate and paratenic hosts, including amphibians, r…

Toxocara cati and related ascarid roundworms are among the most common parasites of cats, with wild felids shedding eggs that contribute to environmental contamination and pose a zoonotic risk to peop…

Serosurveys consistently reveal high Toxoplasma exposure in wild felids, reflecting their role as both definitive hosts and predators of infected prey. This overview synthesizes prevalence patterns ac…

African lions and other wild felids can be infected with Trypanosoma, tsetse-transmitted protozoan parasites better known for causing sleeping sickness in humans and nagana in livestock. This overview…

Anthrax, caused by the spore-forming bacterium Bacillus anthracis, periodically kills wildlife in African ecosystems, and lions and other scavenging felids become exposed by feeding on infected herbiv…

Babesia are tick-transmitted protozoa that infect red blood cells and can cause anemia, and they have featured prominently in felid disease, most dramatically in the drought-linked mortality of Sereng…

African carnivores, including lions, leopards and cheetahs, host a rich diversity of blood-borne parasites that molecular surveys continue to uncover. This overview surveys the diversity of hemoparasi…

In ecosystems like Kruger, African buffalo serve as the maintenance host for bovine tuberculosis, and lions acquire infection chiefly by feeding on diseased buffalo. This overview surveys the transmis…

Canine distemper virus (CDV) is a morbillivirus closely related to measles and rinderpest that has expanded its host range far beyond dogs to infect lions, tigers, leopards, hyenas, seals and many oth…

Long-term studies that radio-collar wild felids provide rare opportunities to determine causes of death, including disease, with precision. This overview surveys how telemetry-based monitoring quantif…

Climate change is reshaping the distribution and intensity of wildlife disease, with implications for felids through effects on vectors, reservoirs and host stress. This overview surveys how warming a…

Wild felids rarely carry a single pathogen, and interactions among co-infecting agents can determine whether infection is benign or deadly. This overview surveys the concept of co-infection synergy in…

Understanding why some felids tolerate pathogens that sicken others requires comparing immune function across wild and domestic cats. This overview surveys comparative felid immunology, examining diff…

Feline immunodeficiency virus causes an AIDS-like syndrome in domestic cats yet has long been assumed benign in its wild hosts. This overview examines the evidence for and against that assumption, com…

Demodex mites live in the skin of many mammals, usually harmlessly, but can proliferate to cause demodectic mange when host immunity falters. This overview surveys reports of demodicosis in wild and c…

Beyond individual illness, bovine tuberculosis may reshape lion populations and social behavior over time. This overview synthesizes research and modeling on how chronic TB reduces survival and reprod…

Detecting Mycobacterium bovis and related mycobacteria in wild carnivores is notoriously difficult, complicating both research and management. This overview surveys the diagnostic toolkit applied to f…

Captive felids in zoos and sanctuaries require systematic disease surveillance both for their own health and as sentinels for emerging threats. This overview surveys health monitoring in captive cat c…

Lions are unusually social among cats, and their pride structure shapes how pathogens spread through populations. This overview surveys the interplay between lion social organization and disease trans…

Because domestic dogs often act as the reservoir feeding canine distemper into wild carnivores, vaccinating dogs around protected areas has become a key conservation tool. This overview surveys the lo…

African lions carry their own feline immunodeficiency virus, FIV-Ple, which exists as several deeply divergent lineages that often co-circulate within and among populations. This overview synthesizes…

Surveys of the gut parasites of wild cats, typically based on fecal examination, provide a window into felid health, diet and environmental exposure. This overview surveys the common gastrointestinal…

Wild cats host a diverse array of helminths, including roundworms such as Toxocara and Toxascaris, tapeworms like Spirometra and Taenia, hookworms and lungworms, acquired largely through their prey. T…

Hemotropic mycoplasmas, formerly called Haemobartonella, attach to red blood cells and can cause infectious anemia in felids, with wild cats carrying these bacteria across many populations. This overv…
