RESUMO

Clinical isolates of the Bacteroides fragilis group (n=29) were collected from patients attending a tertiary care hospital in Medellin, Colombia, during 2012 and were tested for susceptibility to four carbapenems using the Clinical and Laboratory Standards Institute (CLSI) Etest method. Overall rates of percent susceptibility were as follows: meropenem, 93.1%; imipenem, 100%; ertapenem, 96.6%; and doripenem, 93.1%. This is the first study to show rates of resistance of Bacteroides spp. to carbapenems in Colombia among a species formerly thought to be fully susceptible to this type of antimicrobial.

RESUMO

Objective. This study evaluates the bacterial contamination rate of items in the hospital setting that are in frequent contact with patients and/or physicians. By determining the bacterial species and the associated antibiotic resistance that patients are exposed to. Methods. Hospital-based cross-sectional surveillance study of potential bacterial reservoirs. Cultures from 30 computer keyboards, 32 curtains, 40 cell phones, 35 white coats, and 22 ties were obtained. Setting. The study was conducted an urban academic 650-bed teaching hospital providing tertiary care to the city of Medellin, Colombia. Results. In total, 235 bacterial isolates were obtained from 159 surfaces sampled. 98.7% of the surfaces grew positive bacterial cultures with some interesting resistance profiles. Conclusion. There are significant opportunities to reduce patient exposure to frequently pathogenic bacteria in the hospital setting; patients are likely exposed to many bacteria through direct contact with white coats, curtains, and ties. They may be exposed to additional bacterial reservoirs indirectly through the hands of clinicians, using computer keyboards and cell phones.
