Detection of extended spectrum beta-lactamases and resistance in me

Apenas uma cepa apresentou sensibilidade a todos os antimicrobianos testados. The main limitations of this study were the absence of previous studies on ESBL-producing Enterobacteriaceae in bulk-tank milk from comparable dairy regions of Colombia, which would have estimated frequency according to national productive conditions, and a larger budget, which would allow larger sample size and different time periods.

Beeta of genus and species of isolates was performed with a commercial biochemical identification kit. However, with its alternate name, the bla gene CTX-Ma was detected first in Colombia in four isolates: Clin Micro biol Infect ; 14 1: Information about CFU values was obtained from the purchase invoice generated by the milk processor.

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.

Antimicrobial resistance in foodborne pathogens–a cause for concern? In the same way, situations in which the choice and provision of antibiotics is in the hands of a person other than the veterinarian may cause variations in bacterial sensitivity along with recurrence of the presentation of microorganisms associated with different pathologies as a bega of not normally performing isolation or evaluation by antibiogram of the causal agent of infection Betancourt et al. An antimicrobial susceptibility test was performed by the agar disc diffusion method and the automatized broth microdilution method.
