This study was perfomed to examine the distribution of causative agent of piglets diarrhea in eastern Chonnam province from February 1994 to March 1995. The causative agents of diarrhea were examined by bacterial culture test, parasitological test and serological test against PED, TGE and Rota. The 35 isolated E. coli were tested for antibiotic sensitivity. The results obtained were as follows. 1. The incidence of 81 piglets with diarrhea was most prevalent as 39.5% in the age of 2 to 4 weeks, compare to 34.6% in the age of 5 to 8 weeks and 16.0% under 1 weeks and 9.9 % in the age of 9 to 11 weeks after birth. 2. The incidence of 81 piglets diarrhea showed bacterial diarrhea(75.3%), viral diarrhea (35.8%) and parasitological diarrhea(18.5%). When compared the isolation frequency of each etiological agent, enteropathogenic E. coli was most prevalent as 55.5% in bacterial diarrhea, rotavlrus enteritis as 18.5% in viral diarrhea and trichuriasis as 13.6% in parasitological diarrhea. 3. The complicated infection of piglets was most prevalent as 41.7% in rotavirus enteritis with enteropathogenic E coli in 24 complicated piglets diarrhea. 4. In antibiotic sensitivity test, isolates showed moderatly resistance to Tobramycin, Amikacin, Imipenem, Trimethoprim/Sulfamethoxazole, Gentamicin, Ampicillin but sensitivty to Ticarcillin/K. The 30 E. coli isolate showed multiple drug resistances in 3 different antibiotics.
