- Abstract
Background: The spreading of resistant and multiresistent bacterias have involved both water and different foods, becoming a serius problem in public health in Latino American countries. Objectives: To study the antimicrobial suscepbility profiles of bacterias isolated from six (taps) houses of different distribution webs and five water bottles of natural sources and or minerals. Classical biochemical test and Kirby-Bauer method were used and the antimicrobial susceptibility was studied by well diffusion method and NCCLS (Nacional Committe for Clinical Laboratory Standards) tables, the limits and de diameters of the inhibition zones for Standard strains were verified. Results: Over the eleven wáter samples analized, 26 isolated were obtained, in which 13 pure strains were identified, seven were negatives rods, identified as Pseudomonas spp. (42,86%), Burkholderia cepacia, Ralstonia piketti (14,29%) and Brevundimonas diminuta 28,57%. From the Gram negative strains 100% presented resistence to Ampiciline 10 μg, 5 were resistant too to Gentamicine 10μg and Streptomicine 300μg (71,43%),one strain was resistant to Minocicline 30μg y Meropenem 10μg (14,29%). It was posibble to isolate 6 colonies of Gram positives cocus, identified as Staphylococcus spp. (66,67%), Enterococcus y Micrococcus (16,67%) with a 100% of resistence to Meticiline 5μg. Conclusions: Bacterias form drinking water in the Riobamaba city can contribute to the global dissemination of antibiotic resistance, for which is necessary to extend the surveillance network to water and soil contaminants.
