We report a case of CTX-M-55-type extended-spectrum β-lactamase (ESBL)-producing Shigella sonnei infection in a 27-year-old Korean woman who had traveled to China. The patient was admitted to the hospital due to abdominal pain, watery diarrhea, and fever (39.3℃). S. sonnei was isolated from her stool specimens, and the pathogen was found to be resistant to cefotaxime due to CTX-M-55-type ESBL. ...
From a total of 320 bacterial samples from wound swab and urine 169 (53%) gram-negative bacteria were isolated, of which 42 (25%) extended-spectrum beta-lactamase (ESBL) producers were detected by double-disk synergy test. ESBL producers were significantly more resistant against amoxiclav, Co-trimoxazole, ciprofloxacin, amikacin and gentamicin than non-ESBL producers. Among the 42 ESBL producer...
coli and Salmonella spp. Out of 200 samples collected from retail markets Durg, Raipur, Rajnandgaon Balod districts Chhattisgarh State, 76 (38) 46 (23%) were found contaminated with E. spp., respectively. Multiple antibiotic resistant (MAR) index varied between 0.00 to 0.88 0.11 for isolates, The isolates screened phenotypically ESBL production multiplex PCR targeting blaTEM, blaSHV, andblaCTX-...
Pseudomonas aeruginosa is one of the most common opportunistic pathogens that cause infections. The drug resistance in may relate to production broad spectrum beta lactamase enzymes. This study aimed detect multidrug resistant, extensively resistant and pan isolates determine frequency extended lactamases enzymes by using a reliable test for detection blaCTX-M1, blaCTX-M2 blaCTX-M3 genes aerugi...

Background and Aims: The rate of urinary tract infection caused by the extended-spectrum-β-lactamase- (ESBL) producing Escherichia coli (E. coli) is increasing worldwide. This study aimed to assess the frequency of blaCTX-M genes in the E. coli isolated from urinary tract infection (UTI) in outpatients. Methods: 240 E. coli bacteria were isolated from the outpatients’ urine samples in the Kerma...
We aimed to analyze the antimicrobial resistance phenotypes and to elucidate the molecular mechanisms underlying resistance to cephalosporins, ciprofloxacin, and azithromycin in Salmonella enterica serovar Typhimurium isolates identified from patients with diarrhea in Shanghai. The isolates showed high rates of resistance to traditional antimicrobials, and 20.6, 12.7, and 5.5% of them exhibited...
This study investigated the resistance of various Salmonella strains to beta-lactam antibiotics. Salmonella Minnesota (36 strains) and Salmonella Heidelberg (24 strains) were isolated from broiler chickens and carcasses by the Disk Diffusion Test and resistance genes blaCTX-M-8, blaACC-1 and blaCMY-2 were detected by PCR. Of the 60 strains tested, 80% were resistant to at least one antibiotic. ...
Escherichia coli sequence type 131 (ST131) is the most frequent antimicrobial-resistant lineage of E. coli, propagating extended-spectrum β-lactamases (ESBL) worldwide. Recently, an alarming rate of increase in isolates of the sublineage C1/H30R-blaCTX-M-27 of ST131 in geographically distant countries was reported. Here, we present the complete genome sequence of the ST131 sublineage C1/H30R E....
infections. The spread of CTXM–positive bacteria considerably changes the way we think about treating community-acquired infections and limits the oral antibiotics that may be administered. This finding has major implications for treating children, who should not be given fluoroquinolones and tetracyclines. The observation that different blaCTX-M alleles, located on plasmids of different sizes,...
