The prevalence of anti-Toxoplasma gondii antibodies in Ghanaian sheep and goats.
The enzyme-linked immunosorbent assay (ELISA) was used to detect anti-Toxoplasma gondii antibodies in 1258 small ruminants (732 sheep and 526 goats) sampled from 28 different locations in the three ecological zones of Ghana. The animals sampled had an overall seroprevalence of 30.5% (384 of the total). Sheep had a higher overall prevalence (33.2%) compared to the goats (26.8%). Animals sampled from the Coastal Savannah and the Forest zones had prevalences of 39.4% and 39.1%, respectively, which were significantly higher (P<0.01) than the prevalence recorded for the drier Guinea Savannah zone (20%). Prevalence of antibodies in female animals (35.8%) was significantly higher (P<0.01) than that for males (21.1%). Significant differences were also observed between breeds and age groups. The ELISA was found to be both highly sensitive (92%) and specific (91%) when compared to the IFAT, which was used as a reference test.
