Tag: Cytauxzoon felis

Limited genetic variability of Cytauxzoon felis apical membrane antigen-1 (ama1) from domestic cats and bobcats

BACKGROUND: Cytauxzoon felis is a tick-transmitted apicomplexan that causes cytauxzoonosis in domestic cats (Felis catus). Even with intensive care, the mortality rate of acute cytauxzoonosis approaches 40% in domestic cats, while bobcats (Lynx rufus), the natural intermediate host of C. felis, remain clinically asymptomatic. However, multiple reports of domestic cats surviving acute disease without any …

Genetic conservation of Cytauxzoon felis antigens and mRNA expression in the schizont life-stage

Abstract Cytauxzoonosis is a highly fatal disease of domestic cats caused by the apicomplexan protozoan Cytauxzoon felis, which is most closely related to Theileria spp. The growing prevalence, high morbidity and mortality, and treatment cost of cytauxzoonosis emphasize the need for vaccine development. Traditional approaches for vaccine development, however, have been hindered by the inability to culture C. felis …
