The oocysts in the feces naturally infected and artificially inoculated with porcine coccidia were observed for the nation-wide survey and for the study of the patho-ecology of the porcine coccidiosis in Korea, respectibly. The results obtained were summarized as follows: 1. The overall infection rate of porcine coccidia was as high as 25.1 % consisting ‘of the regional prevalence rates as in Ho-Nam(33.2%), in Yeong-Nam(25.1%), in the Centural area(22.7%) and in Cheju(10.3%). 2. It was revealed that the infection rate in young piglets (29.5%) was higher than in those growers (21.8%) and the sows(21%). 3. The sporulation time of the oocysts collected was recognized as 3~8 days variable along to the species. Meanwhile, the prepatent period was around 8 days in the artificial infection experiment. The piglets inoculated with sporulated oocysts showed the diarrhea first, then the oocysts were excreted afterwards. 4. Among the species isolated, two types of coccidia (E. perminuta 29.3% and E. cerdonis 20.2%) were predominant, and the others (Isospora suis 4.4% and E. scabra 4.4%) were seen with minor importance. 5. In this survey, E. cerdonis, E. porci and E. suis were firstly identified to occur in swine in Korea. 6. In the aspect of the infection types, the single- (52.9%) or 2-species mixed infection (26.5%) were most prevalent.
