초록

Toxoplasma gondii is a species of parasitic protozoa in the genus Toxoplasma. The definitive host of T. gondii is the cat, but the parasite can be carried by the vast majority of warm-blooded animals, including humans. It is often found in the tissues of food animals including pigs and sheep. To determine the regional prevalence of infection with T. gondii, bloods (n=300) from domestic pigs and tissues (n=200) from slaughter pigs in Gyeongnam province were tested using an enzyme-linked immunosorbent assay (ELISA) and a polymerase chain reaction (PCR) for detection of antibody and antigen. A total of 115 sero-positive pigs were identified for a prevalence rate of 38.3%. Of the 50 herds from domestic pigs tested, 34 had at least one sero-positive pig for a herd prevalence rate of 68.0%. Sero-positive rates of pigs in fattening farm were higher than that of pigs in breeding company. Sero-positive rates of sows were higher than that of growing pigs. Seasonally, sero-positive rates of pigs were highest in winter (80.0%) and lowest in spring (23.8%). According to farm size, sero-positive rates of pigs were higher in small size farms (${\leq}$2,000) than that of big size farms (>2,000). However, none of the bloods (n=300) from domestic pigs and tissues (n=200) from slaughter pigs were positive for T. gondii specific DNA by PCR.
