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 .
