The genus Acinetobacter comprises several groups of closely related species, including the Acinetobacter calcoaceticus-Acinetobacter baumannii complex (1) and a number of hemolytic species (2). Currently, the A. calcoaceticus-A. baumannii complex comprises five validly named species, including A. calcoaceticus, A. baumannii, A. pittii, and A. nosocomialis (3); the recently named species A. seif...

Introduction: Infections caused by carbapenem-resistant Acinetobacter baumannii(CRAB) is a health problem due to the limited therapeutic options available. This study was carried out evaluate main mechanisms of resistance carbapenems in CRAB last 10 years Brazil and describe susceptibility profile tigecycline polymyxins these isolates. Material methods: A systematic review according Prisma PUBM...

The main objective is to study the genotypic and characterization of plasmid deoxyribonucleic acid content resistant isolates in Erbil city. A total 39 Acinetobacter baumannii were isolated from 102 diabetic foot ulcer patients, whose ages ranged 37 88 y, attending various medical wards hospitals city, Iraq, between May 2020 March 2021. Isolates tested for presence extended-spectrum beta-lactam...

BACKGROUND The emergence of carbapenem-resistant Acinetobacter baumannii (CRAB) was observed in a Kenyan hospital from 2009 to 2010. Further investigation of the dissemination of CRAB isolates and the molecular characterization of associated resistance determinants were therefore performed. METHODS Antibiotic susceptibilities were determined by broth microdilution and Etest. Metallo-β-lactama...

INTRODUCTION blaOXA-48, blaNDM-1 and blaCTX-M-3 are clinically relevant resistance genes, frequently associated with the broad-host range plasmids of the IncL/M group. The L and M plasmids belong to two compatible groups, which were incorrectly classified together by molecular methods. In order to understand their evolution, we fully sequenced four IncL/M plasmids, including the reference plasm...

Within the ESBL family the most common genes are temoneira (blaTEM) and sulfhydryl variable (blaSHV) with increasing reports of cefotaximase (blaCTX-M) [4]. The blaSHV and the blaTEM subgroups arise from mutational changes due to point mutations in the genes resulting in subtypes. Examples include blaSHV which differs from blaSHV-1 due to a single mutation of an amino acid from glycine to serin...

the emergence of multidrug resistance (mdr) and extensively drug resistance (xdr) in acinetobacter baumannii has made an important challenge in the treatment of infections caused by this organism. the ability of carbapenemase production is one of the main mechanisms for the emergence of mdr and/or xdr in a. baumannii. the aim of this study was to detect carbapenemase producer a. baumannii. in t...
