SUMMARY:

Studies investigating causes of death in the feline species have grown and provide information for owners, veterinarians and companies in the veterinary field. Felines diseases were diagnosed in the states of Mato Grosso and Rio de Janeiro by necropsy performed by the Laboratory of Veterinary Pathology (LPV) of the Federal University of Mato Grosso (UFMT) and the Pathological Anatomy Sector (SAP) of the Federal Rural University of Rio de Janeiro (UFRuralRJ) between 2020 and 2021. All felines included in the study underwent molecular surveillance and immunohistochemistry to diagnose SARS-CoV-2 infection. During this period, 96 feline necropsies were performed in these institutions. Of these, 45% (43/96) were necropsy performed by the LPV/UFMT team, and 55% (53/96) were performed by the SAP/UFRuralRJ team. Conclusive diagnoses were 81% (35/43) at LPV/UFMT and 90% (48/53) at SAP/UFRuralRJ. The study presented 96 diagnoses, as some felines had more than one conclusive diagnosis, which points to the leading causes of death in cats in Mato Grosso and Rio de Janeiro. The leading cause of death in both states are inflammatory and parasitic diseases. One feline from Mato Grosso showed staining in the epithelial cells of the nasal concha, bronchi, and bronchioles in the lung and renal tubules at the immunohistochemical examination with anti-SARS-CoV nucleocapsid antibodies and anti-SARS-CoV-2 spike protein. The present study provides results of diseases affecting felines in two different regions of Brazil. We reinforce immunohistochemical examination as an auxiliary method in diagnosing cats infected by SARS-CoV-2.
