Susceptibility testing of Escherichia coli isolates from urines: are we at risk of reporting false antibiotic resistance to co-amoxiclav?
Sir, The BSAC recently published a change to the recommended inhibition zone diameter breakpoint for testing susceptibility of Enterobacteriaceae to amoxicillin/clavulanate (co-amoxiclav), whereby the maximum zone diameter for inferring resistance was increased from 14 to 20 mm. There was no change to the MIC breakpoint, which remains at 8 mg/L. This change resulted in a significant increase in...
متن کاملComparison of Disc Diffusion, Broth Microdilution and Modified Hodge Test Susceptibility Testing Of Escherichia coli Isolates to Beta-Lactam Antibiotics
ABSTRACT Background and Objective: One of the main tasks of clinical microbiology laboratories is to determine antibiotic resistance profiles in common pathogens and ensure the selection of effective antibiotics for certain infections. The aim of this study was to compare the methods of disk diffusion, broth microdilution and modified Hodge test i...
متن کاملMolecular characterization and antibiotic susceptibility pattern of caprine Shiga toxin producing-Escherichia coli (STEC) isolates from India
The present study was conducted to detect the occurrence, serotype, genotype, phylogenetic relationship and antimicrobial resistance pattern of STEC from healthy goats of West Bengal, India. From the 125 faecal samples collected from healthy goats, 245 isolates were identified as Escherichia coli. The E. coli harbouring any gene for Shiga toxins (stx1/stx2) was detected in 36 (14.7%) of the 245...
متن کاملDetection of TEM, SHV and CTX-M Antibiotic Resistance Genes in Escherichia coli Isolates from Infected Wounds
ABSTRACT Background and Objective: Escherichia coli is one of the most common causes of hospital-acquired infections. Extended-spectrum β-lactamase (ESBL)-producing E. coli strains are resistant to third-generation cephalosporins. The three main genes involved in ESBL production are TEM, SHV and CTX-M. Detection of ESBL-producing E. coli is of importan...
متن کاملPhenotypic and Genotypic Study of Antibiotic Resistance among Escherichia coli Isolates from Human Urinary Infection Cases in Bojnord Province
Background and Objective: Bacterial agents are the most common causes of urinary infection with Escherichia coli as the major causative organism. Accordingly, the current study aimed to determine the antibiotic resistance among Escherichia coli isolates from human urinary infection cases. Materials and Methods: The current experimental study was carried out on 50 specimens of positive cultures...
