Judul: Kajian Histopatologi Hati Kucing yang Terpapar Feline Infectious Peritonitis (FIP)
Abstrak: This study was aimed to know the histopathological aspect of Feline Infectious Peritonitis (FIP) that was focused on its liver. In this study three cats, from October 2009 until June 2010, that were diagnose suffering FIP were used as case samples. An observation on gross lesion and histopathology were done based on the regular protocol of Pathology Laboratory of Faculty of Veterinary Medicine, Bogor Agricultural University. The histopathological change of liver was evaluated with paraffin method and stained with Haematoxilin-Eosin dyes. The histopathological changes were observed under light microscope. The results showed that all evaluated livers were found in general congestion, inflammation multifocal, degeneration, necroses, inflamed cell infiltration. One of cases was found existing a secondary infection which appearing bacteria colonies in central vein lumen of lobules. In addition it also notes that pathological evaluation finding gave a general change of FIP on other organs such as hydropascites, icterus, perihepatitis, pancreatitis, gastroenteritis, and inflammation granulomatus in some organs.

Abstrak: This study was aimed to clarify the morphophatological aspect of Feline Infectious Peritonitis (FIP) that was focused on its kidney. In this study three cats that were diagnoses suffering of FIP were used as case samples. The morphophatological observation was done based on the regular protocol of Laboratory Pathology, Faculty of Veterinary Medicine, Bogor Agricultural University. The morphophatological changes of kidneys were evaluated by performing necroption and the histopathological changes were observed under light microscope after stained with Haematoxilin-Eosin dyes method. The results of gross findings showed that all evaluated kidneys have congestion and granulomatous nephritis. Histopathologically, these changes demonstrated general congestion, degeneration and necrosis of epithelial tubules, dilatation of tubules and infiltration of inflammatory cells (macrophages, lymphocytes and plasma cells) in the interstitial spaces with mild fibrosis. It could be conclude that interstitial granulomatous nephritis and congestion are the main morphophatological findings of the cat kidney which suffering of FIP.
