BACKGROUND In this study a large random collection (n=2188) of facultative oligotrophic bacteria, from 90 water samples gathered in three consecutive years (2007-2009) from three different sampling sites of River Mahananda in Siliguri, West Bengal, India, were investigated for the presence of class 1 integrons and sequences of the amplification products. METHODOLOGY/PRINCIPAL FINDINGS Replica...

Four streptomycin-resistant isolates of Xanthomonas oryzae pv. oryzae (YNA7-1, YNA10-2, YNA11-2, and YNA12-2) were examined via PCR amplification for the presence of class 1, class 2, and class 3 integrons and aadA1 and aadA2 genes, which confer resistance to streptomycin and spectinomycin. The class 1 integrase gene intI1 and the aminoglycoside adenylyltransferase gene aadA1 were identified in...

b ackg r oun d : pseudomonas aeruginosa is one of the most important oppor- tunistic pathogens responsible for various types of infections. children suffer significant morbidity and mortality due to nosocomial infections. the aim of this study was to investigate the presence of class1 integron, blabel, blaper, blakpc, blavim, blaimp and blaoxagroup-1  genes among p. aeruginosa isolates at child...

conclusions the population structure of the a. baumannii isolates in our hospitals was genetically diverse. a significant association between xdr pattern and presence of class 1 integron (p < 0.001) was found indicating that many antibiotic resistance determinants are involved in development of xdr strains. materials and methods during a three-year study, clinical isolates of a. baumannii were ...

Objectives: Dissemination of antimicrobial resistance (AMR) is a global issue that requires the adoption of a "One-Health" approach promoting integration of human and animal health. Besides culture-dependent techniques frequently used for AMR surveillance, cultivation-independent methods can give additional insights into the diversity and reservoir of AMR genetic determinants. Integrons are mol...

Class 2 integrons (Tn7) were found in all randomly selected epidemic (n = 27) and preepidemic (n = 13) strains of multiresistant Shigella sonnei biotype g. A class 1 integron was also found in two epidemic strains. Gene cassettes within these integrons account for resistance to commonly used therapeutic agents.

Background and Aim: The increasing prevalence of resistance (MDR) Enterobacteriaceae in Indonesia has caused concern regarding human health. Citrobacter freundii reportedly targets the gastrointestinal tract animals is a common cause foodborne diseases associated with diarrhea, peritonitis, meningitis, brain abscess, bacteremia, urinary infection. This study aimed to estimate MDR presence Class...

BACKGROUND Integrons are the major reasons of multidrug resistance (MDR) among enteropathogenic bacteria. Occurrence of horizontal gene transfer between integron-carrying microorganisms and other enteric bacteria may increase the rate of emergence of integron-associated antibiotic resistance. OBJECTIVES The objective of this study was to investigate class 1 integrons among members of enteropa...

OBJECTIVES To date, little is known about the molecular basis of antimicrobial resistance in Bordetella bronchiseptica, an important respiratory tract pathogen in pigs, dogs and cats. The aim of this study was to identify genes coding for trimethoprim resistance present in porcine B. bronchiseptica and to determine their localization, transferability and association with other resistance genes....
