Contaminación bacteriana y resistencia antibiótica en celulares de médicos del Hospital Vicente Corral Moscoso. Cuenca-2012

Abstract

Background: The use of electronic devices like cell phones in health units, especially in hospitals is very common. These are widely available items without any restriction neither caution to disinfect them and its use is more often. It may be a source of contamination for nosocomial infections. Studies show bacterial contamination above 90% in mobile medical staff found pathogenic bacteria such Staphylococcus aureus sensitive, methicillin-resistant staphylococci, Enterococcus, Corynebacterium, Klebsiella, Clostridium, Enterobacter, Acinetobacter, Serratia, Escherichia coli, Pseudomonas, Proteus. Aims: To determine the bacterial contamination and antibiotic resistance in the cell of "Vicente Corral Moscoso" hospital medical staff.

Methods: In this study, a surface culture of 276 cell phones was done, physicians´ property, In senior physicians, medical residents and interns of the “Vicente Corral Moscoso” hospital. We used a swab from the surface to collect the sample and cultured on blood agar and EMB agar, to isolate and identify bacteria with biochemical tests and then susceptibility testing with the Kirby-Bauer technique.

Results: The 93.84% of the mobile devices are contaminated. The treating physician’s cells showed a intense level of contamination (p = 0.001), mainly by Staphylococcus aureus (p = 0.022), Staphylococcus epidermidis (p = 0.012), Enterobacter aerogenes (p = 0.019). Male staff shows more intense contamination by Enterobacter aerogenes (p = 0.024). Oxacillin resistance in Staphylococcus aureus is 40.7% in the isolated. Enterobacteriaceae found a high degree of resistance to third generation cephalosporin suggesting the presence of ESBL strains.
