Prevalence and molecular analysis of multidrug-resistant Acinetobacter baumannii in the extra-hospital environment in Mthatha, South Africa BJID
Anane A,Yaw; Apalata,Teke; Vasaikar,Sandeep; Okuthe,Grace Emily; Songca,Sandile.
ABSTRACT Introduction: The presence of Acinetobacter baumannii outside hospitals remains unclear. This study aimed to determine the prevalence of multidrug-resistance (MDR) A. baumannii in the extra-hospital environment in Mthatha, South Africa and to investigate the frequency of carbapenemase-encoding genes. Material and Methods: From August 2016 to July 2017 a total of 598 abattoir samples and 689 aquatic samples were collected and analyzed presumptively by cultural methods for the presence of A. baumannii using CHROMagar™ Acinetobacter medium. Species identification was performed by autoSCAN-4 (Dade Behring Inc., IL) and confirmed by the detection of their intrinsic blaOXA-51 gene. Confirmed MDR A. baumannii isolates were screened for the presence of...

Gusatti,Carolina de Souza; Bertholdo,Lauren Martins; Otton,Letícia Muner; Marchetti,Desirée Padilha; Ferreira,Alessandra Einsfeld; Corção,Gertrudes.
This is the first report of an Acinetobacter baumannii from clinical origin carrying the blaOXA-58 gene in Brazil. The isolate included in this study was from a patient during an outbreak in Porto Alegre, RS, Southern Brazil, in 2007. It was resistant to most of the beta-lactams tested, it has also the blaOXA-65 gene and the ISAba1 sequence located upstream to both blaOXA genes detected and it has a MIC of imipenem of 64 μg/mL.
Tipo: Info:eu-repo/semantics/article Palavras-chave: BlaOXA-58; ISAba1; BlaOXA-65; Carbapenemases; Acinetobacter baumannii.
