conclusions our study indicated a high frequency of cotrimoxazole resistance gene in e. coli isolates from ilam and tehran (milad) hospitals, and sul genes had a major role in cotrimoxazole resistance of these isolates. materials and methods one-hundred and forty-four e. coli isolates were identified during march 2007 to april 2012 at ilam hospitals and milad (tehran) hospital. antibiotic susce...
Dissemination of Class 1 Integron among Different Multidrug Resistant Pseudomonas aeruginosa Strains
ABSTRACT Background and objectives: The present study was conducted to detect class 1 integrons and evaluate antibiotic susceptibility patterns among clinical isolates of P. aeruginosa. Methods: Sixty clinical samples from blood, tracheal wounds, burns and uri...
In 200 sulfonamide-resistant Portuguese Salmonella isolates, 152 sul1, 74 sul2, and 14 sul3 genes were detected. Class 1 integrons were always associated with sul genes, including sul3 alone in some isolates. The sul3 gene has been identified in isolates from different sources and serotypes, which also carried a class 1 integron with aadA and dfrA gene cassettes.
BACKGROUND Sulfonamide resistance is very common in Escherichia coli. The aim of this study was to characterize plasmids carrying sulfonamide resistance genes (sul1, sul2 and sul3) in E. coli isolated from pigs and humans with a specific objective to assess the genetic diversity of plasmids involved in the mobility of sul genes. METHODS A total of 501 E. coli isolates from pig feces, pig carc...
BACKGROUND Acute infectious diarrhea is one of the most important causes of morbidity and mortality worldwide. OBJECTIVES The objective of this study was to characterize antimicrobial resistant diarrheagenic Escherichia coli strains isolated from diarrheic children in Tehran, IR Iran. PATIENTS AND METHODS In total, 550 stool samples from diarrheic pediatric patients, aged less than 60 month...
Antimicrobial resistance was studied in Escherichia coli strains isolated from urine samples of 457 patients suffering from urinary tract infection. High prevalence of class 1 integrons (43.56%), sulfamethoxazole resistance genes sul1 (45.54%) and sul2 (51.48%) along with occurrence of quinolone resistance genes was detected in multi drug resistance isolates.
We report the draft genomes of twoSphingopyxissp. strains isolated from a chloraminated drinking water distribution system simulator. Both strains are ubiquitous residents and early colonizers of water distribution systems. Genomic annotation identified a class 1 integron (intI1) gene associated with sulfonamide (sul1) and puromycin (pac) antibiotic resistance genes.
Sulfonamide-trimethoprim-resistant Aeromonas salmonicida and motile Aeromonas spp. from diseased fish of the GERM-Vet study carried the sul1 gene together with mostly cassette-borne trimethoprim resistance genes, including the novel gene dfrA28. The seven dfrA and dfrB genes identified were located mostly in class 1 integrons which commonly harbored other gene cassettes.
The occurrence and removal of 49 antibiotics 11 selected antibiotic resistance genes (ARGs) were investigated in 2 vertical subsurface flow (VF) constructed wetlands (1.5 m2 each): an unsaturated (UVF) unit a partially saturated (SVF) (0.35 m out 0.8 m) operating parallel treating urban wastewater. Thirteen detected influent wastewater, 6 which present all samples. SVF showed statistical signif...
To assess the presence and distribution of the sul genes (sul1, sul2, and sul3) and plasmids in human-mediated environments of north Vietnam, we examined a total of 127 sulfonamide-resistant (SR) bacterial isolates from four shrimp ponds (HNAQs), a city canal (HNCs) and three fish ponds that received wastewater directly from swine farms (HNPs). Results from the SR isolates revealed that sul gen...
