Spread of carbapenem-resistant Acinetobacter baumannii global clone 2 in Asia and AbaR-type resistance islands.
In this surveillance study, we identified the genotypes, carbapenem resistance determinants, and structural variations of AbaR-type resistance islands among carbapenem-resistant Acinetobacter baumannii (CRAB) isolates from nine Asian locales. Clonal complex 92 (CC92), corresponding to global clone 2 (GC2), was the most prevalent in most Asian locales (83/108 isolates; 76.9%). CC108, or GC1, was...
متن کاملFirst report of carbapenem-resistant Acinetobacter nosocomialis isolates harboring ISAba1-blaOXA-23 genes in Latin America.
In recent years, different resistance genes have been found in Acinetobacter spp., especially in the species A. baumannii. We describe two isolates of carbapenem-resistant A. nosocomialis harboring ISAba1-blaOXA-23 and blaOXA-51 found in patients from the city of Porto Alegre, southern Brazil. To the best of the authors' knowledge, this is the first report of carbapenem-resistant A. nosocomiali...
متن کاملDissemination of bla OXA - 23 in Acinetobacter spp . in China : main roles of 1 conjugative plasmid pAZJ 221 and transposon Tn 2009
15 Production of OXA-23 carbapenemase is the most common reason for the increasing 16 carbapenem resistance in Acinetobacter spp. This study was conducted to reveal the genetic 17 basis of the blaOXA-23 dissemination in Acinetobacter spp. in China. A total of sixty-three 18 carbapenem-resistant OXA-23-producing Acinetobacter spp. isolates, representing different 19 backgrounds, were selected fr...

A total of 63 carbapenem-resistant OXA-23-producing Acinetobacter sp. isolates, representing different backgrounds, were selected from 28 hospitals in 18 pro...
متن کاملCharacterization of a Novel Plasmid Type and Various Genetic Contexts of blaOXA-58 in Acinetobacter spp. from Multiple Cities in China
BACKGROUND/OBJECTIVE Several studies have described the epidemiological distribution of blaOXA-58-harboring Acinetobacter baumannii in China. However, there is limited data concerning the replicon types of blaOXA-58-carrying plasmids and the genetic context surrounding blaOXA-58 in Acinetobacter spp. in China. METHODOLOGY/PRINCIPAL FINDINGS Twelve non-duplicated blaOXA-58-harboring Acinetobac...
