Caecal coccidiosis was diagnosed in Rajasri birds of nineteen weeks age presented for routine postmortem examination at Department of Veterinary Pathology, College of Veterinary Science, Hyderabad. Clinically birds showed inappetence, depression, ruffled feathers, bloody diarrhea, anemia and mortality of about 21 birds out of 65 birds () for a period of two weeks. Grossly, extremely ballooned caeca, white necrotic foci visible from outside of caeca, haemorrhagic enteritis, watery ingesta mixed with mucus and blood were observed. Upon opening of the caeca, semi liquid bloody mass was observed and liver was pale. Faecal smear examination revealed coccidial oocyst. Histopathological examination of caecum revealed coccidian lifecycle stages with destruction of different layers of the caecum. | 2019 8 9 577-580 EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 8 Number 09 2019 Journal homepage http Original Research Article https Incidence of Caecal Coccidiosis in Adult Layer Chicken M.
