  Toxoplasmosis is an infectious disease caused by the protozoan parasite Toxoplasma gondii that infects a wide range of animals, including man and birds. The objective of the study was to isolate T. gondii in pigs slaughtered at the Addis Ababa abattoir. A total of 290 sera were examined for T. gondii antibodies (IgG) using the Direct Agglutination Test (DAT) of which 111 pigs (38.28%; 95% confidence interval [CI]: 32.65%-44.14%) were seropositive. Hearts of fifty seropositive pigs and two pooled pig heart samples (portion of 4 pig hearts per pool) were used for the study. For the isolation of T. gondii, 50 g heart tissue was ground, digested with acid-pepsin and inoculated intraperitoneally into mice (5 mice/sample). Viable T. gondii was isolated from hearts of 24 of 50 (48%; 95% CI: 33.7%-62.6%) seropositive pigs and from the two pooled seronegative pig hearts. All isolates were asym.. Read More»
