[ survey on prevalence of different Eimeria species in goats in Shiraz suburbs]

ABSTRACT

To identify different Eimeria species in domestic goats [Ca pra hircus]. Cross-sectional study. One hundred and fifty domestic goats [75 goats below one year age and 75 above one year] in some rural areas around Shiraz. Fecal sampling, counting the oocysts [OPG] in fecal samples were done by Clayton- Lane floatation method. In this respect, oocysts were collected, maintained in 2.5% potassium dichromate at 28[degree sign] C and, identified on the basis of morphological and biological characteristics of sporulated oocysts. One hundred and ten goats out of 150 [73.3%] were identified as infected with at least one species. Seven Eimeria species including Eimeria arloingi, E.parva, E.ninakohlyakimovae, E. pallida, E.faurei, E.christenseni and E.granulosa were diagnosed in a decreasing Prevalence rate. No significant difference was evident between mean OPG in <1 and >1 year -old goats. Except for 17 goats [15.45%] the other animals were infected with more than one species. This study revealed occurance of some highly pathogenic Eimeria species [such as E. arloingi in Shiraz area which cause acute coccidiosis, particularly in kids
