Coccidia oocysts in the faeces of farmed ostrich (Struthio camelus) chicks in Botswana

Coccidia oocysts were demonstrated in the faeces of 53 (about 34%) of 156 apparently healthy ostrich chicks. Young chicks had the highest proportion of infestation while those more than 9 weeks old had no oocysts at all in their faeces. These coccidia may be considered no pathogenic since the infected chicks grew normally without any evidence of diarrhoea.
