Acinetobacter baumannii is an emerging nosocomial pathogen with also emerging resistance to different antibiotics. Multidrug and pan drug-resistant clinical isolates were reported worldwide. Here we report the first evidence of pan drug-resistant environmental isolate of A. baumannii. The isolate was recovered from the effluent of secondary treated municipal wastewater of the City of Zagreb, Cr...

Introduction: Enterobacter cloacae strains have been isolated from Eastern Cape hospitalised patients. Methodology: We have molecularly characterised blaOXA-48-, blaIMPand blaVIM-expressing E. cloacae isolates demonstrating resistance to carbapenems from five hospitals by multilocus sequence typing. Organism identification and antimicrobial susceptibility testing was done using automated system...

This study aimed to evaluate the prevalence of carbapenemase-producing Enterobacteriaceae in Luanda, Angola. A total of 157 rectal samples were collected from children visiting a pediatric hospital in Luanda in March 2015. Fifty-seven imipenem-nonsusceptible enterobacterial isolates were recovered, most of which were non-clonally related. The blaOXA-181 (50/57) and blaNDM-1 (7/57) carbapenemase...

Acinetobacter sp isolates deserve special attention once they have emerged globally in healthcare institutions because they display numerous intrinsic and acquired drug-resistance mechanisms. This study assessed the antibiotic susceptibility profile, the presence of the genetic marker blaOXA-23, and the clonal relationship among 34 nosocomial isolates of Acinetobacter spp obtained at a hospital...

Mosquitoes transmit serious human diseases, causing millions of deaths every year. Use of synthetic insecticides to control vector mosquitoes has caused physiological resistance and adverse environmental effects in addition to high operational cost. Insecticides of botanical origin may serve as suitable alternative biocontrol techniques in the future. The present investigations were made to eva...

Sir, Worldwide, resistance to carbapenems, imipenem and meropenem is widespread among Acinetobacter causing infections and most resistant isolates are also resistant to many other antibiotic classes. Several class D b-lactamases can hydrolyse carbapenems, conferring resistance. The blaOXA-23 gene was the first to be found and was originally identified in a conjugative plasmid from a clinical Ac...
