rabbit farm in Tirupati in the month of August. All the rabbits were regularly feed with carrots and green grass. Post mortem examinations of the rabbits were done and primary gross patho-logic changes were noticed in the intestines. Intestines were re-moved along with their contents and they were subjected to exam-ination for Eimeria infection. Faecal samples were examined for the presence of parasitic oocysts by direct microscopic examina-tion, sedimentation technique. Positive samples were subjected to floatation technique using saturated salt solution (Long et al., 1976) to collect and concentrate the oocysts. The collected oocysts were transferred into 2.5% aqueous potassium dichromate solution (w/v) and incubated at 25–28ºC to allow the oocysts to sporulate and examined periodically to determine the sporulation time. A modified McMaster technique was used to determine oocysts counts per gram of faeces (OPG) in samples.
