Q.75 A 4-yeаr-оld cаt nаmed “Whiskers” was brоught tо the vet clinic with corneal opacity, a pot belly, watery discharge from eyes and nose, and fatigue. Labs show high levels of CD4+ T cells, indicating T-cell depletion in gut lymphoid tissue and high levels of total protein concentration, which is consistent with an exudate, ultimately producing the pot belly (see x-ray showing effusion). A laparoscopic exam revealed multiple granulomas in the serosa of the jejunum(see photo). PCR was positive for feline coronavirus and, based on his clinical presentation, was diagnosed with feline infectious peritonitis. What immunologic response leads some cats to manifest feline infectious peritonitis (the virulent form of infection with feline coronavirus) instead of the more common and healthier avirulent clinical presentation?
