title: Coccidia in sheep in South Australia.
abstract: Faecal samples from 136 sheep from four different locations in South Australia were examined to determine the types and numbers of Eimeria spp. present. Coccidian oocysts were detected in 80% of the sheep and 11 different species of Eimeria were identified. The species detected (and their prevalence) were E. crandallis/E. weybridgensis (76%), E. ovina (55%), E. ovinoidalis (54%), E. granulosa (49%), E. parva/E. pallida (44%), E. intricata (37%), E. ahsata (31%), E. faurei (24%), and E. punctata (1%). No major differences were observed in the patterns of infection between the four locations examined. Faecal samples were also collected each month for a year from 48 lambs at two of the locations and oocyst counts were found to decrease markedly in all lambs after 6 months of age but to persist at low levels until the end of sampling at 17 months of age.
