Abstract

The present study was conducted to investigate the phage types(PT) of Salmonella enteritidis(SE) isolated from animals and human patients in Korea during the period 1993-1999. SE were isolated from chickens including the layer and broiler, duck, rat, swine and human patients in nationwide scale. A total of 231 non-human and 14 human SE strains were phage typed and 80.4%(197/245) of SE isolates tested could discriminate as a ten SEPTs including the RDNC by the 10 standard phages, which were brought from the Central Public Health Laboratory in England. In analysing of phage types both animal and human SE isolates, SEPT 4(55.4%) was the most prevalent in domestic animals including the layer(39.3%) and broiler(64.5%), duck(55.5%), and swine(75.0%) since 1993. About 57% of the S enteritidis from human was SEPT 4. Along with SEPT 4, SEPT 1, SEPT 6a, SEPT 7 and SEPT 7a var, SEPT 9b, SEPT 15, SEPT 21b and SEPT 22 were also found from animal and human SE isolates. SEPT 4(40.0%) was isolated from frozen chicken meats imported from China along with SEPT 7 and 7a var strains in this study. In conclusion, SEPT 4 was the most predominant SEPT in our country regardless of animal or human hosts including the Che-Ju island and almost exclusively found in domestic poultry(layer and broiler). During the review period, SEPT 4 has already been spreading continually among the animal hosts since 1993.
