This survey was carried out to investigate the seroprevalence of antibodies to Neospora caninum in Korean indigenous cattle that was raised in central area province Gyeongnam, Korea. A total of 719 sera were tested for N. caninum antibodies using ELISA (Herdcheck anti-Neospora, IDEXX Laboratories Inc., Westbrook, Maine USA). Seroprevalence of individual and farm were 29.8%(214/719) and 53.2%(50/94). Regional seropositive rates of the samples were 61%(47/77), 23.3%(7/30), 13.8%(49/355), 37.6%(77/205), 65.4%(34/52) at Changwon, Jinhae, Gimhae, Miryang, Yangsan, respectively. It showed difference at the age and on the herd size of farms. A herd of cattle above the age of 5 was more infective than under 4 years. And in seroprevalence by herd size farms having under 30 heads was top(35.7%). Seropositive 214 herds of N. caninum antibidies were tested for brucellosis by test tube. Positive rate of double infection was 16.4%(35/214).
