Like many of the other epidemic diseases (such as parvovirus or calicivirus) found in serological studies of lions, there have been no consistent signs of clinical disease for FCoV. The life cycle within cats is similar to Babesia spp except the infectious sporozoites invade leucocytes as well as erythrocytes. It contains the carbohydrate-digesting enzyme, salivary amylase, which is responsible for the majority of starch digestion. Infected erythrocytes are then ingested by ticks where they undergo gamogony and fertilization within the midgut, then invade the salivary gland cells. Each pride has a well-defined territory consisting of a core area that is strictly defended against intruding lions and a fringe area where some overlap is tolerated. Historically, they lived across much of Europe, Asia, and Africa, but now they are mainly found in parts of Africa south of the Sahara.
