Risk factors for community-acquired urinary tract infections caused by ESBL- producing Enterobacteriaceae — A case-control study in a low prevalence country. Data were initially analyzed by descriptive statistics through measures of central tendency and frequency distribution.

Timely identification of ESBL- producing Enterobacteriaceae strains is essential in the monitoring of the development of antimicrobial resistance and in the implementation of infection control measures for the protection of public health WHO, However, sincethe enzyme cefotaxime-munich CTX-M became one of the most frequent and ESBL-producing Eschericha coli emerged estenddo an important pathogen in the community Blanco et al.

It is also possible that the low occurrence of ESBLs in these farms is due to little use of oactamase and lacttamase since the selection pressure that drives ESBL evolution has usually been attributed to the intensive use of oxyimino-cephalosporins, mainly third-generation cephalosporins Gniadkowski, Journal of Antimicrobial Chemotherapy Estehdido resistance is expanding rapidly throughout the world and has become a problem in both human and veterinary medicine FDA, ; Reist et al.

Enterobacteriaceae isolates that are positive for CTX-M have been found in food-producing animals and their products Carattoli, ; Smet et al.

It is important to evaluate whether foods of animal origin constitute a reservoir of resistance genes. Pfaller MA, Segreti J. Bacteria suspicious of producing ESBL were isolated in 6.

A total of 14 antibiotics were evaluated and interpreted according to CLSI standards: The low frequency of ESBL-producing Enterobacteriaceae in bulk-tank milk could be a result of the high hygiene standards required by milk processing companies in Antioquia to purchase raw milk. Carbapenems are the most potent beta- lactam antibiotics because of their wide spectrum Bush,and these bacteria are still sensitive to this family of antibiotics, which makes a battery of effective antibiotics available for treating infections caused in humans and animals.
