The present paper describes Felis catus papillomavirus (FcaPV) type 5-associated cutaneous mass in a Domestic Shorthair cat. Histological examination revealed multicentric epidermal acanthosis with papillomavirus-associated cytopathic changes, which progressed to a tumor lobule with intact basement membrane. An association between FcaPV-5 and the cutaneous lesions was confirmed by detection of virus antigen and genes using immunohistochemistry, polymerase chain reaction (PCR), sequencing analysis, and in situ hybridization. Based on these findings, the lesions were diagnosed as FcaPV-5-associated viral plaques and Bowenoid in situ carcinoma (BISC). To date, this is the first reported case of FcaPV-5 infection in a cat in Japan, and the second case reported worldwide. For the first time this papillomavirus type is associated with BISC development.

A Japanese black feedlot steer suddenly died after exhibiting astasia and cramping of the extremities. Necropsy of the animal revealed that the right kidney was enlarged and pale with severe nephrolithiasis. The urinary bladder displayed mucosal hemorrhage. Upon bacteriological investigation, Proteus mirabilis was isolated from the liver, spleen, right kidney, lungs and urine. Histopathological examination revealed necrotizing suppurative nephritis with the presence of numerous gram-negative bacilli and fibrinous suppurative cystitis with no bacilli. Immunohistochemical analysis revealed that the bacteria and cytoplasm of the macrophages stained positively with P. mirabilis antiserum. Electron microscopy revealed the presence of numerous bacteria in the renal tubules. To our knowledge, this is the first report describing the histopathological aspects of nephritis caused by P. mirabilis in cattle.
