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…

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…

Sylvatic plague, caused by the bacterium Yersinia pestis, circulates among rodents in the American West, and mountain lions become exposed by preying on infected rodents and lagomorphs. This overview…

Some Toxoplasma infections in southern sea otters involve unusual atypical genotypes, including a so-called Type X strain rarely seen in domestic cats. This overview surveys research suggesting that w…

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…

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…

As conservation efforts seek to rewild felids and support natural range expansion, disease becomes a critical consideration. This overview surveys the disease dimensions of rewilding and range recover…

Cats, both domestic and wild, are the only definitive hosts in which Toxoplasma gondii completes sexual reproduction and sheds environmentally resistant oocysts. This overview surveys the ecology of t…

Beyond the pathogenic FIV and FeLV, felids carry feline foamy virus, a generally apathogenic retrovirus that nonetheless offers a useful marker of contact and transmission. This overview surveys felin…

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…

High-throughput sequencing has opened a new era of virus discovery, allowing researchers to catalog the viromes of wild felids without prior knowledge of which pathogens to seek. This overview surveys…

Molecular tools have revolutionized the study of how pathogens spread among carnivores, including felids, by reading the genetic signatures of viruses and parasites. This overview surveys the use of m…

Careful necropsy and pathological examination underpin much of what is known about causes of death and disease in wild felids. This overview surveys the role of standardized post-mortem investigation…

Capturing and sampling wild felids is costly and risky, so researchers increasingly turn to non-invasive methods, especially analysis of feces, to detect pathogens and parasites. This overview surveys…

A felid’s diet largely determines its parasite burden, as many worms and protozoa are acquired by eating infected prey. This overview surveys how prey-mediated transmission shapes the parasitic fauna…

Vaccines against feline immunodeficiency virus exist for domestic cats but raise complex questions when considered for wild felids harboring their own endemic lentiviruses. This overview surveys the i…

Interpreting antibody tests in wild felids is complicated by cross-reactivity, where antibodies to one pathogen react with tests for a related agent, blurring diagnoses. This overview surveys the diag…

Serological surveys, which detect antibodies as evidence of past or present infection, are a workhorse of wildlife disease epidemiology. This overview surveys how serosurveys reveal pathogen exposure…

Beyond domestic cats, wild felids such as bobcats and pumas sustain natural sylvatic cycles of Toxoplasma, shedding oocysts that infect wild prey and contribute to environmental contamination. This ov…

Toxoplasma is maintained in both domestic cycles centered on house cats and sylvatic cycles driven by wild felids, and the two intersect in complex ways. This overview surveys how domestic and wild tr…

This comprehensive study screened thousands of samples from many felid species plus hyenas for feline immunodeficiency virus and sequenced isolates to map viral diversity. The authors confirmed that F…
