Mutations in gyrA and parC genes in nalidixic acid-resistant Escherichia coli strains from food products, humans and animals.
Mutations in quinolone targets were analysed in 80 unrelated nalidixic acid-resistant (NALR) Escherichia coli strains whose nalidixic acid and ciprofloxacin MICs ranged from 32 to >256 mg/L and 0.03-64 mg/L, respectively. These strains were isolated from food products (23) and faecal samples from humans (15) and healthy animals (42). Thirteen nalidixic acid-susceptible (NALS) E. coli strains we...
متن کاملPhylogenetic analysis of multidrug-resistant Escherichia coli clones isolated from humans and poultry.
Chicken products represent a source for multidrug-resistant Escherichia coli causing extraintestinal infections (ExPEC) in humans. We applied phylogenetic analysis to a collection of E. coli strains from both hosts (poultry/humans) to improve our understanding of the origin and spread of ExPEC in humans. The dataset consisted of 58 sequences among 172 E. coli strains from human extraintestinal ...
متن کاملCharacterization of multidrug-resistant Escherichia coli isolates from animals presenting at a university veterinary hospital.
In this study, we examined molecular mechanisms associated with multidrug resistance (MDR) in a collection of Escherichia coli isolates recovered from hospitalized animals in Ireland. PCR and DNA sequencing were used to identify genes associated with resistance. Class 1 integrons were prevalent (94.6%) and contained gene cassettes recognized previously and implicated mainly in resistance to ami...
متن کاملThe ability of uropathogenic Escherichia coli isolates in biofilm formation on urinary catheter and association with bcsA and draE genes
The product biofilm by E.coli strain can cause serious problem for human health. Catheter is considered to be s suitable place for colonization of microorganisms, so that in %5-10 of patients who used catheter for only one day and also in all patients who used it for over 28 days, this colonization of bacteria is observed on catheter. This study is come out in order to compare biofilm formation...
متن کاملNucleotide sequences of 16 transmissible plasmids identified in nine multidrug-resistant Escherichia coli isolates expressing an ESBL phenotype isolated from food-producing animals and healthy humans.
OBJECTIVES Nine extended-spectrum β-lactamase (ESBL)-producing Escherichia coli isolated from healthy humans and food-producing animals were found to transfer their cefotaxime resistance marker at high frequency in laboratory conjugation experiments. The objective of this study was to completely characterize 16 transmissible plasmids that were detected in these bacterial isolates. METHODS The...
