Objective: In addition to assessing the phenotypic development of biofilms and beta-lactamases, in current study, Pseudomonas aeruginosa isolates from intensive care units (ICU) patients with prevalent drug resistance are being evaluated. Methods: Standard CLSI recommended protocols were utilized detect beta-lactamases such as extended-spectrum β-lactamases (ESBL), metallo beta-lactamase (MBL),...

Respiratory isolates of Klebsiella pneumoniae in Korea during 2002-2003 were studied to determine the prevalence and types of extended-spectrum beta-lactamases (ESBLs) and plasmid-mediated AmpC beta-lactamases (PABLs). ESBL-production was tested by double-disk synergy, and genotypes of beta-lactamases were determined by PCR and sequencing. ESBLs were detected in 28.4% of 373 isolates, and the m...

The main objective is to study the genotypic and characterization of plasmid deoxyribonucleic acid content resistant isolates in Erbil city. A total 39 Acinetobacter baumannii were isolated from 102 diabetic foot ulcer patients, whose ages ranged 37 88 y, attending various medical wards hospitals city, Iraq, between May 2020 March 2021. Isolates tested for presence extended-spectrum beta-lactam...

BACKGROUND Ventilator-Associated Pneumonia (VAP) is the most frequent intensive-care-unit (ICU)-acquired infection. The aetiology of VAP varies with different patient populations and types of ICUs. METHODOLOGY A prospective study was performed over a period of 15 months in a tertiary care hospital to determine the various aetiological agents causing VAP and the prevalence of multidrug resista...

background extended-spectrum β-lactamase (esbl)-producing klebsiella pneumonia has become widespread in hospitals and is increasing in community settings. most of k. pneumonia that harbor these enzymes, display resistance to other unrelated antimicrobial agents and thus, often pose a therapeutic dilemma. objectives this study was conducted to determine the prevalence of esbl-producing k. pneumo...

conclusions the high prevalence of quinolone resistance genes, which indicates antibiotic resistance, in the imam reza hospital of mashhad is a major concern. hence, the antibiotics prescription policy should be revised, and infection control measures should be improved. results eighty-six (43%) isolates were ciprofloxacin-resistant. the pct identified 85 (42.5%) of 200 e. coli isolates as esbl...

Despite the recent global spread of CTX-M beta-lactamases in Escherichia coli isolates from community-acquired urinary tract infections (CA-UTIs), their dissemination has been little studied in developing countries. In a 2-year prospective study, we documented the prevalence of extended-spectrum beta-lactamases (ESBLs) in E. coli that were responsible for CA-UTIs in Phnom-Penh, Cambodia. Ninety...

Despite the discovery of novel beta-lactamases such as extended-spectrum beta-lactamases (ESBLs), imported AmpC, and carbapenem-hydrolyzing beta-lactamases at least a decade ago, there remains a low level of awareness of their importance and how to detect them. There is a need to increase the levels of awareness of clinical laboratories about the detection of newer beta-lactamases. Therefore, a...

Twelve Salmonella typhimurium strains resistant to broad-spectrum cephalosporins were isolated from cases of gastroenteritis during 1996 to 1998 in Russia, Hungary, and Greece. Resistance was due to the production of CTX-M-type extended-spectrum beta-lactamases encoded by similar 12-kb plasmids. By pulsed-field gel electrophoresis, all strains shared the same chromosomal type. These data sugges...
