Bacterias multirresistentes en Centros de Cuidado de niños

Abstract

Purpose:To describe the antibiotic resistance of isolated bacteria on the surfaces of child care centers. Methods:Swabs were used to sample the surfaces in 266 child care centers in Bogotá (Colombia). Bacterial characterization and susceptibility patterns were verified using a computerized system. Results:A total of 151 different bacteria were obtained, primarily in the kitchens (36%). Staphylococcuswas a frequent find, especially: S. hominis, S. saprophyticusand S. epidermidis;2.7% were resistant to methicillin. Klebsiella oxytocawas the most isolated bacteria in kitchens, with high resistance to antibiotics. Conclusion:This investigation shows the importance of identifying the bacteria present in different environments to which children are exposed to continuously supervise hygiene habits in child day care centers.

“…Ampicillin control antibiotics shown considerable inhibition of Enterobacteri aerogens as well as other Staphylococcus species, such as S. saprophyticus and S. epidermidis. Since plasmid-coded beta-lactamases are produced by most S. aureus strains, especially hospital strains (like MRSA, or methicillin-resistant S. aureus), they are resistant to penicillin [41,42,43] which may explain why most of the isolates were resistant to ampicillin control disc. Because of the selective character of the media or the rigorous growth needs of the bacteria (for example, strong anaerobic microorganisms cannot thrive under aerobic conditions), no growth of bacterial isolates may occur [44] thus the 19% no growth may have been due to strict conditions required for growth of microbes.…”
