    The present study was conducted to investigate the prevalence of Eimeria infection in 1,300 slaughtered chickens from 130 farms in Gyeongnam, Jeonnam, Jeonbuk, Gyeongbuk and Chungnam during the period from October 2002 to August 2003. The results obtained are summarized as follows : 1. The prevalence of Eimeria infection in 130 chicken farms was 76.9% and Eimeria infection rates of Gyeongnam, Jeonbuk, Gyeongbuk, Jeonnam and Chungnam were 80%, 75%, 70%, 42.9% respectively. Tongyoung has the highest infection(94.4%) than others city in the Gyeongnam. 2. The prevalence of oocysts infection level in 1,300 slaughtered chickens from 5 districts was 33.4% and that of Jeonbuk has the highest rate(42%) and Gyeongbuk has the lowest rate(20%). Prevalence of OPG level of slaughtered chicken in Tongyoung has the highest rate(42.8%) and other cities has the lowest rate(22.9%) in Gyeongnam. 3. Mixed infection rates of over 2 types were 79% and triple infection has the highest infection(33%) among the infection types. 4. Kind of E. spp. were E. acerulina, E. mivati, E. necatrix, E. maxima, and E. tenella and E. tenella has the highest infection rate(78%) and E. necatrix has the lowest infection rate(36%) among the Eimeria spp. 5. The monthly prevalence of Eimeria infection was shown higher in July(94.4%) compared with others month and Jun was shown lower(57.9%). But, level of OPG infection was shown higher in summer season(July, August ; over 40%) than that of winter season(January, February ; 23.1%, 16%). 6. The prevalence of Eimeria infection by drug administration for treatment and prevention or non-administration was shown 71.4%, 82.6% and 72.3%, respectively, and so infection rate of chicken farms was similar independent on drug administration or not. 7. The prevalence of Oocysts infection level of chicken farms by administrated drug for treatment was shown lower(25.3%) than for prevention(35.4%) and non-treatment(36.2%). 8. The prevalence of Oocysts infection level by drug administration under 2 days for treatment was shown higher infection rate(32.2%) than over 3 days(20%) and also under 2 days for prevention has similar tendency of that of treatment and so, it was conclusion that administration of drug over 3 days has the effect for treatment and prevention of Eimeria infection. 9. The prevalence of oocysts infection level by Age for prevention has various level from 48.8% to 22.9% but on 22∼25 days was shown the most higher ratio(48.8%) and on 19∼21 days was shown the lowest rate(22.9%) among the all age groups.
