Hydatidosis of Cattle with Secondary Bacterial Invaders

Abstract

Speciemens of hydatid cysts were collected from infected liver and lung of cattle , multilocullar cysts , different sizes , milky in coulor , some of them superficial while others embedded in the parenchyma of the organs . Bacteria were isolated from liver and lung infected with hydatid cysts in cattle slaughterd in Diwania slaughter house. S.aureus and C.Pyogenes were isolated from the liver , while Streptococcus spp and C. pyogenes were isolated from lung hydatid cysts . Bacterial colonies were identified by culturing on enriched and selective media with various biochemical tests . All bacterial species were sensitive to Ciprofloxacin and Genta- mycin While it is resistant to Carbencillin and Ampicillin. Histopathological study revealed the hydatid cysts in liver and the lung were surrounded by fibrous tissue . Coagulative necrosis were noticed in liver tissue while casouse necrosis was in lung tissue .
