MELGAREJO-T, Nancy et al. First isolation of Salmonella Javiana with KPC-2 in Paraguay. Rev. salud publica Parag. [online]. 2017, vol.7, n.2, pp.51-56. ISSN 2307-3349.  https://doi.org/10.18004/rspp.2017.diciembre.51-56.

At the global level have emerged over the years, microorganisms resistant to various antimicrobial agents that have been incorporated to the therapeutic arsenal. Several mechanisms of resistance have emerged in recent years, highlighting the emergence of carbapenemases in enterobacterias, entity which Klebsiella pneumoniae carbapenemasa (KPC), being one of the most important, originally identified in the United States in 1996.

In Paraguay, the first isolates of KPC carbapenemasecarrying strains were obtained in september 2009, from which the presence of several Enterobacteria species was confirmed, with Klebsiella pneumoniae being the most prevalent among them.

According to data from the reference center, Salmonella enterica serotype Typhimurium is the most common serovar identified in stool samples to date, and the Javiana serotype the fourth.

This report describes the first KPC-2 carbapenemase isolate in Salmonella enterica serovar Javiana isolated in February 2015 from a fecal sample. In addition, in samples from the same patient, Klebsiella pneumoniae species resistant to carbapenems were isolated by the presence of the same enzyme (KPC-2) in orotracheal secretion and vancomycin-resistant Enterococcus faecalis in fecal samples.

Keywords : Salmonella; KPC; carbapenemases; enterobacterias.
