DOI:10.30954/2277-940X.06.2019.12
Abstract:
Coccidiosis in poultry is still considered as one of the main diseases affecting performance of poultry reared under intensive production systems. Coccidiosis was diagnosed in Rajasri birds upon routine postmortem examination conducted at Department of Veterinary Pathology, College of Veterinary Science, Hyderabad. PM examination of 423 birds conducted during a period of one month, out of which 136 birds were diagnosed with intestinal coccidiosis (32.15%) and 120 birds with caecal coccidiosis (28.36%). Clinically birds showed weakness, somnolence, ruffled feathers, pale comb, mucoid bloody diarrhea and death. Coccidiosis was initially diagnosed on the basis of faecal smear examination and histopathological alterations in intestines. Gross examination of birds showed pale muscle, dehydrated and emaciated carcass. Extremely ballooned intestine and caeca and haemorrhages in intestinal mucosa were seen. Upon opening of the small intestines and caeca, watery ingesta mixed with mucus and blood was observed. Faecal smears made from duodenum, jejunum, ileum and caecum revealed coccidial oocysts. Histopathological examination of intestine and caecum revealed coccidia lifecycle stages with destruction of different layers of the intestine and caecum with infiltration of heterophils and mononuclear cells (MNC).
