The present study was conducted to investigate the prevalence, biochemical properties and plasmid profiles of Salmonella organisms isolated from wild birds in Daegu area during the period from May, 1999 to August, 2000. Twenty strains of Salmonella were identified from 192 samples of heron feces and 86 samples of pigeon feces. Among Salmonella isolates, S. montevideo were the most frequent serotype (16 strains), 3 strains of them were S. typhimurium and the other one was untypable. The biochemical properties of 20 strains of Salmonella isolated were in accordance with the traditional characteristics of Salmonella spp. in the majority of biochemical test such as IMViC, carbohydrate fermentation and amino acid decarboxylation. The majority of isolates were highly susceptible to amikacin, ampicillin, amoxicillin, carbenicillin, cephalothin, ciprofloxacine, chloramphenicol, enrofloxacin, furazolidone, gentamicin, kanamycin, nalidixic acid, polymixin B and sulfamethoxazole, while they were moderately susceptible to streptomycin and tetracyclin. However, the majority of them were highly resistant to nitrofurantoin. In plasmid profile, 21.1 kilobase (Kb), 20 Kb and 13.2 Kb fractions were common to three S. tvphimurium and one untypable strains, and no fraction was shown in all strains of S. montevideo.

Five hundred and nine strains of Esherichia coli isolated from domestic animals and 23 strains of Salmonella isolated from 237 pigs were tested for drug resistance and distribution of R plasmids. Seventy two per cent of E. coli strains isolated from domestic animals fed with antibiotics-containing feeds were resistant to tetracycline(TC), streptomycin(SM), chloramphenicol(CM), ampicillin(AM) and kanamycin(KM), alone or in combination thereof, but about 2% of E. coli strains isolated from domestic animals received no antitiotics were resistant to TC and SM. Among resistant strains, 45.4% were found to be singly resistant to TC, SM or KM, whereas 54.6% were resistant to two or more antibiotics. The most common resistance pattern was double resistant to TC and SM(33.7%) and followed by triple ones to TC, SM and AM(4.9%). About 67% of resistant E. coli carried R factors which were transferable to the recipients by conjugation. Seventy eight per cent of Salmonella strains isolated from pigs were resistant to TC, SM, AM, and KM, alone or in combination thereof, and the most common resistance pattern was resistant to TC and SM(38.9%) slimilary to E. coli and about one half of resistant Salmonella carried R factors. There was no difference in numbers of TC-resistant Coliform for 6 weeks after stopping administration of antibiotics, but they were decreased to one seventh at the 13th week.
