On August 16, 2012, the Colorado Department of Public Health and Environment was notified of two patients at an acute-care hospital in Denver with carbapenem-resistant Enterobacteriaceae (CRE), specifically Klebsiella pneumoniae (CRKP), isolated from respiratory specimens during July-August. Both isolates produced

Microbial populations in wastewater treatment plants (WWTPs) are increasingly being recognized as environmental reservoirs of antibiotic resistance genes. PCR amplicons for plasmid-mediated quinolone resistance determinants qnrA, qnrB, and qnrS were recorded in samples from a WWTP in Vancouver, British Columbia.

The co-existence of carbapenemase, 16S rRNA methylase and mutated quinolone resistance-determining regions (QRDRs) can cause serious difficulty in treating infections with multidrug-resistant Acinetobacter baumannii. In this study, we aimed to determine the mechanisms of imipenem, amikacin and ciprofloxacin resistance in

Extended-spectrum beta-lactamase (ESBL) producing organisms cause wide spectrum of diseases including urinary tract infection, cholangitis, intra-abdominal abscess or pneumonia but rarely meningitis. The present report a successful nonsurgical, medical treatment in a child with Escherichia coli ESBL meningitis with acute
