7 of total 14 antimicrobial agents. In comparison with isolates in 1998, resistance to antimicrobialswas more frequent among the isolates in 2002. Presence of class 1 integrons was investigated through amplification of the gene with PCR, and could be classified 8 groups by pattern of 4 different amplicons. Class 1 integrons were observed in 67 strains (64.2%)of E. coli from swine in Korea. One and 1.6 kbp of amplicons were revealed to contain aadA1 and aadB-aadA1 gene cassettes respectively. Two... -

11주가 dhfrX-orfF-aadA2 integron gene cassette를, 1주가 aadA2 integron을 보유하였다. 그러나 35주 모두가 class 2 integron gene cassette와 class 3 integron gene cassette는 보유하지 않은 것으로 나타났다. 35주의 PEGE 유형은 5가지로 분류되었으며, 31주가 pulsotype A로 나머지 4주는 pulsotype B, C, D, E형으로 각각 나뉘어졌다. 이러한 결과로 볼 때 경북지역에서 사람과 돼지에서의 S. enterica serovar Typhimurium에 의한 살모넬라중은 몇 종류 유행주의 전파에 의한 것임을 보여줄다. dhfrX-orfF-aadA2 integron gene... -

많았고, ampicillinampicillin/sulbactam-tetracycline형이 14.5%, ampicillin-streptomycin-chloramphenicol-tetracycline형이 10.8%였다. Integron에 대한 연구 결과 integron 보유율은 19%로 20주에서 class 1 integron을 가지고 있었고 gene cassette는 20%만 확인이 되었다. 확인된 gene cassette는 aadA2, blaP1과 dfrA12-aadA2, dfr17-aadA5, aadA7이였다. 연도별 분리균의 유연관계를 확인 하고자 가장 분리율이 높은 S. Enteritidis 50주에 대해서 PFGE를 수행한 결과 3가지 Pulsotype으로 나눠어졌다. 3주를 제외한 모든 균주는... -

광범위한 내성을 나타내었고, 한국에서는 드문 IMP-1형 metallo-${eta}$-lactamase (MBL)를 생성하는 균주임이 확인되었다. A. baumannii 1625는 약 2.5 kb 크기의 class 1 integron을 갖고 있었으며, 이 integron내에 aminoglycoside계열 내성 유전자인 accA4, carbapenem 계열 내성 유전자인 $bla_{IMP-1}$, 광범위한 ${eta}$-lactam 내성 유전자인 $bla_{OXA-2}$ 유전자 cassette들이 차례대로 위치해 있음을 확인하였는데, 이것은 IMP-1형과 OXA-2형 ${eta}$-lactamase의 유전자를 같은 integron내에 동시에 갖는 새로운 배열 및... -

of the isolates were multidrug resistant. The dog isolates (12.3%) harbored class 1 integrons, of which the dfrA12-aadA2 cassette was most frequent (66.7%). The only class integron in serovar Albany was located on a conjugative plasmid. Two ESBL-producing isolates (i.e., a serovar Krefeld and a serovar Enteritridis) carried blaTEM and blaCTX-M, and the blaTEM gene in both was horizontally transferred. Of the plasmid-mediated quinolone resistance genes tested, only qnrS (4.9%) was detected. Most... -

to their antimicrobial resistance phenotypes. Four of the AR E. coli carried class 1 integrase gene (intI1), a gene associated with multi-drug resistance. Pulsed-field gel electrophoretic analysis showed no genetic relatedness among AR E. coli isolated from different facilities; however, cross-transmissions between horses or horses and environments were detected in two facilities. Although cross-transmission of AR E. coli in horses and their environments was generally low, our study suggests a... -

16 Aeromonas (A.) salmonicida strains isolated from diseased fish and environmental samples in Korea from 2006 to 2009 were investigated in this study. Tetracycline or quinolone resistance was observed in eight and 16 of the isolates, respectively, based on the measured minimal inhibitory concentrations. Among the tetracycline-resistant strains, seven of the isolates harbored tetA gene and one isolate harbored tetE gene. Additionally, quinolone-resistance determining regions (QRDRs) consisting... -

Among the phenicols, resistance was approximately 79% and 29% for chloramphenicol and florfenicol, respectively. Molecular detection revealed that the incidence rates of the floR, cmlA, cat1, cat2 and cat3 were 29, 31, 16, 13, and 0%, respectively. Additionally, 10% of the isolates were positive for both floR and cmlA. As these antimicrobial agents may potentially induce cross-resistance between animal and human bacterial pathogens, their prudent use in veterinary medicine is highly recommended. -
