Blattella germánica (Blattodea: Blattellidae) como potencial vector mecánico de infecciones asociadas a la atención en salud (IAAS) en un centro hospitalario de Villavicencio (Meta-Colombia)

Objective. Identify the species of cockroaches and bacteria associated with their exoskeleton in a hospital in Villavicencio (Meta, Colombia). Methods. The cockroaches were captured manually in kitchen, emergency room, intermediate intensive care unit, outpatient service and newborn nursery. The collected individuals were subjected to a primary isolation in BHI broth, then move on to solid media (blood and MacConkey). Identification and sensitivity testing was performed by automated method. Results. 24 nymphs and adults of Blattella germanica were collected. It was isolated and identified Klebsiella pneumoniae with intermediate susceptibility to meropenem (MIC 4) and resistance to cephalosporins (cefepime and cefuroxime) (> 16), Proteus vulgaris with cephalosporin resistance (Ceftriaxone, Cefuroxime) (MIC > 16), Enterobacter cloacae resistant to cephalosporins (cefoxitin, cefuroxime, ceftriaxone) (MIC > 16). Enterococcus faecium, Enterococcus rafinosus, Staphylococcus xylosus and Enterococcus faecalis. 80% of the isolated bacteria showed some degree of resistance to antibiotics. Results. These insects could play an important role in the transmission of health care associated infections (HCAI). Due to the presence of cockroaches in hospitals and the report of HCAI and bacterial resistance in several health centers in the Department of Meta, it is necessary to establish the relationship of these insects with these events.
