Reduced Susceptibility to Extended-Spectrum β-Lactams in Vibrio cholerae Isolated in Bangladesh
β-lactams are antibiotic molecules able to inhibit cell wall biosynthesis. Among other mechanisms, resistance in Gram-negative bacteria is mostly associated with production of β-lactamase enzymes able to bind and hydrolyze the β-lactam ring. Extended-spectrum β-lactamases extend this ability also to third- and fourth-generation cephalosporins, as well as to carbapenems and monobactams. Vibrio c...
متن کاملSalmonella enterica: Serotyping, Drug Resistance & Extended Spectrum of β-Lactamase (ESBLs)
Background & Objective: Genus Salmonella has more than 2400 serotypes. The two major groups are S.enterica and S.bongori. Important serotypes are situated in S.enterica group. Antibiotic therapy in salmonellosis is restricted to typhoid fever and acute infections. After the first reporting of resistance in S.Typhimurium DT 104, nowadays, developing of resistance in Salmonella, specially, ESBL p...
متن کاملRelation between Resistance to Antipseudomonal β-Lactams and ampC and mexC Genes of Pseudomonas aeruginosa
Background: In order to select a better antibiotic choice for treatment of Pseudomonas aeruginosa infections, this study was conducted to determine the frequency of resistance to some antipseudomonal β-lactams in P. aeruginosa isolates from patients in Tehran, Iran. In addition, the relation between presence of genes known to be responsible for resist...
متن کاملAssociation of Transferable Quinolone Resistance Determinant qnrB19 with Extended-Spectrum β-Lactamases in Salmonella Give and Salmonella Heidelberg in Venezuela
Four nontyphoidal Salmonella strains with resistance to extended-spectrum cephalosporins and nonclassical quinolone resistance phenotype were studied. Two S. Give were isolated from pediatric patients with acute gastroenteritis, and two S. Heidelberg were recovered from raw chicken meat. Phenotypic characterization included antimicrobial susceptibility testing and detection of extended-spectrum...
متن کاملResistance to Extended-Spectrum β-Lactamases in Salmonella from a Broiler Supply Chain
The prevalence of extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae varies worldwide, however, the incidence of ESBL-producing environmental Salmonella isolates is increasing. Salmonella is still one of the most important pathogens that occur in the poultry supply chain. Therefore, this study analyzed the susceptibility of Salmonella isolates collected from a poultry supply chai...
