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...

AIM The aim of this work was to detect antibiotic resistance in Gram-negative bacteria isolated from subclinical mastitis in cattle in West Bengal. MATERIALS AND METHODS The milk samples were collected from the cattle suffering with subclinical mastitis in West Bengal. The milk samples were inoculated into the nutrient broth and incubated at 37°C. On the next day, the growth was transferred i...

AIM To assess the prevalence of antimicrobial resistance producing extended-spectrum β-lactamases (ESBL) (blaTEM, blaSHV, and blaCTX-M) genes in Escherichia coli isolated from chicken meat, chevon meat, raw milk, and human urine and stool samples collected from tribal districts of Chhattisgarh, viz., Jagdalpur, Dantewada, Kondagaon, and Kanker. MATERIALS AND METHODS A total of 330 samples, co...

Objective(s) Different types of extended spectrum beta-lactamases (ESBLs) are encountered in the clinical settings worldwide. There are a few studies regarding the prevalence of ESBL genes among Klebsiella pneumoniae isolates at Tehran especially those of blaPER and blaCTX. The aim of this study was to determine the prevalence of blaSHV, blaTEM ,blaPER and blaCTX genes among clinical K. pneumon...

BACKGROUND The aim of this study was to assess the prevalence of multidrug-resistant Escherichia coli and extended-spectrum â-lactamases (ESBL) pathogens isolated from asymptomatic bacteriuria and urinary tract infections (UTIs), and the relationship between the phylogeny, antimicrobial resistance, and virulence among isolates in residents of 3 long-term care facilities (LTCF) in Krakow, Poland...

Increasing frequency of infections caused by antibiotic resistant Escherichia coli strains producing extended-spectrum β-lactamase (ESBL) needs to be addressed by continuous surveillance and accurate detection of specific ESBLs genes for more effective treatment. A total of 71 β-lactam drug resistant isolates (26 phenotypically ESBL-producing and 45 non-ESBLproducing) were observed to carry app...

OBJECTIVE To determine the molecular characterization of extended-spectrum beta-lactamases (ESBL) isolates from a tertiary center in Saudi Arabia using multiplex polymerase chain reaction (PCR) technique and assess their antibiotic susceptibility pattern. METHODS Prospective study conducted at the Saudi Aramco Dhahran Health Center, Dhahran, Saudi Arabia between April-December 2006. Extended-...
