摘要
Fecal samples from 277 goats on eleven farms in Florida were examined to determine the prevalence and intensity of the multiple species of Eimeria that infect goats in this region. The number of oocysts per gram of feces (OPG) was determined by the modified McMaster technique. Species identification was done following sporulation. Eimeria oocysts were found in 97% of the fecal samples. Goats less than one year of age shed significantly more oocysts than goats greater than one year of age (P < 0.01). Goats of the Nubian breed had the highest OPG counts when compared to Boer, Boer-Spanish crosses, and Saanen breeds. Nine Eimeria spp. were identified. Eimeria arloingi (91%), E. ninakohlyakimovae (82%) and E. alijevi (79%) were the most prevalent species. Other species present were E. caprina (60%), E. christenseni (60%), E. hirci (46%), E. caprovina (29%), E. aspheronica (15%), and E. jolchijevi (9%).
