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.

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
