Abstract

In the present study, we carried out a seropositive survey of Neospora (N) caninum and Toxoplasma (T) gondii in cattle at northern area of Gyeongnam province, Korea. Serum sample was obtained from Holstein cattle (n=248, 44 farms in 5 counties) and Korean indigenous cattle (n=120, 23 farms in 4 counties). All 368 sera were tested for antibodies to N. caninum and T. gondii by an enzyme-linked immunosorbent assay (ELISA). Seropositive of N. caninum at farm and heads were 41.8% (28/67) and 12.8% (47/368), respectively. Twenty-five cattle (6.8%) were seropositive to T. gondii, and eighteen (26.9%) of 67 studied farms had cows seropositive to T. gondii. The seroprevalence of Holstein cattle was much higher than that of Korean indigenous cattle. There was no apparent association of T. gondii seropositivity with age, while the seropositivity for N. caninum was associated with cattle age. The farm of cattle above the age of 5 years (16.8%) was more infective than less than 4 years (9.3%). This is the first report on seroprevalence of N. canium and T. gondii in Holstein and Korean indigenous cattle in Gyeongnam, Korea.
