Abstract :

Coccidiosis is one of the most important causess of enteritis in lambs and kids and can beresponsible for diarrhea, weight loss and even death. In this study a total number of 7 kids nativefrom a flock with range ages between 3 to 4 weeks old with history of depression, loss of appetite,dehydration, emaciation and bloody diarrhea were referred for diagnosis of the disease to clinic ofFaculty of Veterinary Medicine, Islamic Azad University of Shahrekord. Haematological changesincluded decrease in RBCs (3.5 ×106 /mm3), Hb content (5.5 ± 0.3 g/dl) also reduction PCV% (21 ±1.85 %) and leukocytosis (21.35±0.95 × 103 /mm3) with neutrophilia (69±4 %), lymphocytopenia(24±3 % ). At necropsy, gross lesion were observed mostly in the ileum, cecum and proximal colon.This lesions containing cerebriform pattern on the serosal surface of the intestine, severe and diffusea lot of small whitish non- pedunculated nodules on the mucosal surface of jejunum and middleileum with hemorrhage and severe hemorrhage on the mucosa of the cecum and proximal colon.Microscopical study of ileum nodules revealed increased length of crypts, papillary hyperplasias ofthe mucosal epithelium, mild inflammatory reaction and presence of developmental stages of theEimeria in the hyperplastic enterocytes. Microscopic examination of the intestine is required in orderto determine how much damage has occurred, particularly in the areas between the white nodules. Inconclusion Coccidiosis control Programme major importance in domestic animals.
