ABSTRACT

Objetivo. Identificar las especies de cucarachas y bacterias asociadas a su exoesqueleto en un centro hospitalario de la ciudad de Villavicencio (Meta, Colombia). Métodos. Se realizaron capturas manuales de cucarachas en cocina, urgencias, UCI intermedia, consulta externa y neonatos. Los individuos colectados fueron sometidos a un aislamiento primario en caldo BHI, para luego pasar a medios sólidos (sangre y MacConkey). Se realizó identificación y antibiograma por método automatizado. Resultados. Se colectaron 24 ninfas y adultos de Blattella germánica. Se aisló e identificó Klebsiella pneumoniae con sensibilidad intermedia a meropenem (CMI 4) y resistencia a cefalosporinas (cefepima y cefuroxima) (>16), Proteus vulgaris con resistencia a cefalosporinas (ceftriaxona, cefuroxima) (CMI >16), Enterobacter cloacae con resistencia a cefalosporinas (cefoxitina, cefuroxima, ceftriaxona) (CMI > 16), Enterococcus faecium, Enterococcus rafinosus, Staphylococcus xylosus y Enterococcus faecalis. El 80% de las bacterias aisladas presentaron algún grado de resistencia a antibióticos. Conclusiones. Estos insectos podrían jugar un papel importante en la transmisión de las Infecciones asociadas a la atención en salud (IAAS). Debido a su presencia en hospitales y el reporte de IAAS y resistencia bacteriana en varios centros asistenciales en el Departamento del Meta, se hace necesario establecer la relación de estos insectos con estos eventos.


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 ofBlattella germanica were collected. It was isolated and identified Klebsiellapneumoniae 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.
