RODRIGUEZ, Carlos H  and  GRUPO COLABORATIVO ACINETOBACTER ARGENTINA et al. Molecular epidemiology of carbapenem-resistant isolates of Acinetobacter baumannii in Argentina. Rev. argent. microbiol. [online]. 2019, vol.51, n.3, pp.247-250. ISSN 0325-7541.

One hundred sequential, epidemiologically unrelated carbapenem-resistant- Acinetobacter baumannii isolates from 11 hospitals in 10 Argentine provinces were collected between January and August 2016. Genes coding for Ambler class D and B carbapenemases were investigated by PCR using specific primers. All isolates were typed using the 3-locus sequence typing and b/aOXA-51-like sequence-based typing techniques. The blaOXA-23 gene was recovered in all isolates studied. The population of carbapenem-resistant- A. baumannii in Argentina was principally associated with ST1 (45%), ST25 (34%) and ST79 (15%). ST25 was recovered in all the regions studied and CC2 was not detected.

Keywords : Acinetobacter baumannii; CC1; CC25; Carbapenem-resistance.
