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...
Abstract Aim and Background: Actually Acinetobacter baumanii is the most common cause of nosocomial infection. Recent studies detected some classes of integrons in A. baumannii multi-Drug resistance (MDR) isolates. Integron classes introduced the most important pathway for the dissemination resistance genes and the emergence of MDRs species in Acinetobacter. The aims of t...
BACKGROUND/AIM Pseudomonas aeruginosa is the cause of 10% of hospital-acquired infections. The organisms are often multidrug- resistant, mediated mostly by antibiotic-resistant integrons. The aim of this research was to study integron carriage and its association with multidrug resistance in burn and nonburn clinical isolates of P. aeruginosa. MATERIALS AND METHODS A total of 112 P. aeruginos...
We examined the distribution of class I integrons and SXT elements in Vibrio cholerae O1 El Tor strains, isolated in Calcutta, India, before and after the V. cholerae O139 outbreak in 1992. Class I integrons, with aadA1 gene cassette, were detected primarily in the pre-O139 strains; the SXT element was found mainly in the post-O139 strains.
Background: Acinetobacter baumannii is an important opportunistic pathogen which causes complications in hospitalized patients, especially those in ICU. The aim of this study was to determine the frequency of class 1 and 2 integrons in multi-drug resistance A. baumannii and to investigate the association between the presence of integrons and antibiotic resistance patterns. Methods: A total of...
The relationship between the presence and types of integrons and the antimicrobial susceptibility patterns of Acinetobacter baumannii was investigated. A total of 134 non-duplicated A. baumannii isolates, 54.5% (n=73) of which were subsequently found to carry class 1 integrons, were collected from a regional hospital in Taiwan between March and September 2007. Only two types of gene cassette ar...
BACKGROUND AND OBJECTIVES Antibiotic resistance of Pseudomonas aeruginosa remains a major problem in burn patients. The main objective of this study was to determine the antibiotic resistance pattern and frequency of class 1 integrons among P. aeruginosa strains isolated from patients with burn wound infections in a new Burn Centre in Guilan, Iran. MATERIALS AND METHODS The bacterial isolates...
