Salmonella is frequently found in poultry and represent an important source for human gastrointestinal infections worldwide. The aim of this study was to investigate the prevalence, genotypes and antimicrobial resistance of Salmonella serotypes in broilers from Ecuador. Caeca content from 388 at random selected broiler batches were collected in 6 slaughterhouses during 1 year and analyzed by th...

Day-old chicks from 3 hatcheries were placed on bedding paper and brought to a commercial broiler farm between January and July 2016. Sixty-six samples of the paper, which were stained with meconium droppings of the chicks, were collected and examined for isolation of cephalosporin-resistant Enterobacteriaceae. Cefotaxime (CTX)-resistant Klebsiella pneumoniae (1 isolate) and Enterobacter cloaca...

objective(s) extended-spectrum beta-lactamase (esbl) producing bacteria have an important role in nosocomial infections. due to the limited availability of information about the molecular epidemiology of esbl producing bacteria in mashhad, we decided to investigate about tem, ctx and shv esbls among urinary escherichia coli isolates in mashhad, a city in northeast iran. materials and methods   ...

Background: CTX-M-type extended-spectrum β-lactamases (ESBLs) are the most prevalent ESBLs in bacterial members of Enterobacteriaceae family including Klebsiella pneumoniae. The global spread of CTX-M-producing K. pneumoniae is a major concern in most countries including Iran. The aim of this meta-analysis was to determine the relative frequency (RF) of blaCTX-M gene among ESBLs-producing K. pn...

To describe the prevalence and population structure of Staphylococcus aureus bacteria that colonize pigs at slaughterhouses in northeastern China, nose swabs were collected from pigs in two slaughterhouses in Harbin, Heilongjiang Province, China in 2009. S. aureus isolates were characterized by multilocus sequence typing (MLST), spa typing, SCCmec typing, antimicrobial susceptibility testing an...

Escherichia coli isolates harboring CTX-M -lactamases have rarely been obtained from children in the United States. Here we report eight such isolates from seven community-dwelling pediatric patients and their microbiological and clinical correlates. Pediatric E. coli isolates identified as extended-spectrum -lactamase (ESBL) positive by the New York Hospital Queens Clinical Microbiology Labora...

Escherichia coli is generally considered as a commensal inhabitant of gastrointestinal tract of humans and animals. The aim of this study was to gain insight on the distribution of phylotypes and presence of genes encoding integrons, extended β-lactamases and resistance to other antimicrobials in the commensal E. coli isolates from healthy adults in Chandigarh, India. PCR and DNA sequencing wer...

conclusions the rapid dissemination of non clonal multi-resistant ctx-m-1 producing e. coli isolates approved the need for further studies in our medical centers. results a total of 140(70%) non-duplicate esbl positive e. coli were determined. imipenem and amikacin were effective against 100% and 85% of all tested isolates respectively. co-resistance of esbl positive isolates to erythromycin, t...

Fluoroquinolone resistance in Salmonella has become increasingly prevalent in recent years. To probe the molecular basis of this phenomenon, the genetic and phenotypic features of fluoroquinolone resistant Salmonella strains isolated from food samples were characterized. Among the 82 Salmonella strains tested, resistance rate of the three front line antibiotics of ceftriaxone, ciprofloxacin and...
