Abstract:
A cross-sectional serological survey was conducted in order to evaluate, irrespective of abortion, the Toxoplasma gondii infection in pastured sheep from the Campania region of southern Italy. A geographical information system was used in order to uniformly sample the ovine farms (n=117) throughout the entire region. Blood and milk samples were collected from 10 adult sheep (>18 months) on each farm (total number=1170 sheep). Serum samples were tested for the presence of IgG antibodies to T. gondii using a commercial indirect fluorescent antibody test. For each farm, the 10 milk samples collected were pooled in order to obtain a single milk sample per farm (total number=117 milk samples). The 77.8% (91/117) of the farms and the 28.5% (333/11,170) of the sheep resulted positive by serology. In addition, the presence of T. gondii DNA was detected by PCR in 4 milk samples out of the 117 examined (3.4%).
