Identification of carbapenemase genes in Serratia spp

BMC Proceedings volume 8, Article number: P39 (2014) Cite this article

Background

Reports of nosocomial infection due to carbapenem resistant Serratia spp. have become significantly more common. This resistance may be due to production of distinct carbapenemases, such as KPC [1, 2]. This enzyme, initially described in Klebsiella pneumoniae isolates, has also been detected among other organisms, such as Serratia marcescens, emphasizing the global risk of interspecies spread of resistance genes [2, 3]. The aim of this study was to identify carbapenemase genes in Serratia spp. Isolated of nosocomial infection.

Methods

The samples were collected during May/2012 to May/2013. The strains were recovered from urinary tract, tracheal aspirate and blood culture from patients hospitalized Dourados/MS hospital. The identification of Serratia spp. and the sensitivity test was carried out using a Vitek (BioMérieux) automated system. All strains with reduced susceptibility to imipenem or meropenem were screened for carbapenemase production by the modified Hodge test as recommended by the Clinical and Laboratory Standards Institute [4]. The presence of KPC coding gene was assessed by PCR as described by Cuzon et al. (2010) [5].

Results and conclusions

From May/2012 to May/2013, fifty strains of Serratia spp. were isolated. The wards that had the highest incidence of Serratia spp. were the intensive care units (ICUs). The strains identified as producing carbapenemases were evaluated by PCR using primers specific for bla KPC gene. Fourteen Serratia spp. strains were positive in PCR. This work describes the first report of KPC gene in Serratia spp. isolates in Mato Grosso do Sul, Brazil and confirm the high level of resistance of Serratia spp. against carbapenemics. The clinical importance of detecting carbapenemases producing Serratia spp. is to contribute to hospital infection control, reducing the spread of multidrug-resistant microorganisms and providing results that help in choosing the most appropriate antimicrobial, prolonging patient survival.
