RAMIREZ, M. S. et al. Tn7::In2-8 dispersion in multidrug resistant isolates of Acinetobacter baumannii from Chile. Rev. argent. microbiol. [online]. 2010, vol.42, n.2, pp. 138-140. ISSN 1851-7617.

Acinetobacter baumannii is considered an important pathogen in our hospital environment having a well-known capacity to acquire different mechanisms of antibiotic resistance. Previous studies in our laboratory had exposed the high dispersion of class 2 integrons in this species. In the present study, we analyzed 7 multiresistant intI2 positive A. baumannii isolates, 6 of which were found to harbour the Tn7::In2-8 element. Our results demonstrate the unusually high distribution of Tn7::In2-8 among different A. baumannii clones from Chile, suggesting a particular behavior of these elements at geographical level.
