Determination of antibiotic resistance pattern in Escherichia coli strains isolated from animal faeces in a farm house
The present study aimed to evaluate the antibiotic resistance pattern of Escherichia coli strains isolatedfrom animals to ascertain the levels of antibiotic resistance pervasiveness. A total of 28 E. coli strains wereisolated from faecal samples and the antibiotic resistance pattern of E. coli strains was determined by meansof disc diffusion assay. The resistance pattern determined for all stra...
متن کاملMolecular characterization and antibiotic resistance of enterotoxigenic and entero-aggregative Escherichia coli isolated from raw milk and unpasteurized cheeses
The aim of this study was to determine the occurrence of enterotoxigenic and enteroaggregative Escherichia coli strains and antibiotic resistance of the isolates in raw milk and unpasteurized cheese. Out of 200 samples of raw milk and 50 samples of unpasteurized cheeses, 96 and 24 strains of E. coli were isolated, respectively. Polymerase chain reaction (PCR) was used to detec...
متن کاملEvaluation of aminoglycoside resistance ant(2'')-Ia and ant(4')-IIa genes in Escherichia coli strains isolated from urinary tract infection
Background & aim: About 40% of women and 12% of men experience a urinary tract infection at least once in their lifetime. Aminoglycosides are very effective antimicrobial agents. The emergence and spread of antibiotic resistance in Escherichia coli (E. coli) is becoming a global public health concern. The aim of this study was to determine the presence of ant(2'')-Ia and ant(4')-IIa genes in E....
متن کاملMultidrug Resistance in Infants and Children
Bacterial infections may cause disease and death. Infants and children are often subject to bacterial infections. Antimicrobials kill bacteria protecting the infected patients andreducing the risk of morbidity and mortality caused by bacteria. The antibiotics may lose their antibacterial activity when they become resistant to a bacteria. The resistance to different antibiotics in a bacteria is ...
متن کاملDetection of verotoxin (Shiga-like toxin)-producing and eae harboring Escherichia coli in some wild captive and domestic Equidae and Canidae
The aim of this study was to investigate the prevalence of STEC and EPEC strains and E. coli O157 serogroup in some Equidae and Canidae. The fecal samples of 79 animals from 6 different species were evaluated for presence of these strains. All the Isolates were tested for virulence genes using multiplex-PCR. Non-sorbitol fermenting (NSF) Escherichia coli isolates and positive strains for virule...
