Beta-lactamase – Wikipedia, a enciclopedia libre

Journal of hospital infection Carbapenems are the most potent beta- lactam antibiotics because of their wide spectrum Bush,and these bacteria are still sensitive to this esteneido of antibiotics, which makes a battery of effective antibiotics available for treating infections caused in humans and animals. Occurrence of integron-associated resistance gene cassettes located on antibiotic resistance plasmids isolated from a wastewater treatment plant.

The excessive or inappropriate use of antibiotics in farm bea can generate adaptation of bacteria to antimicrobials FAO, ; thus, it has become a matter of great importance for health authorities WHO, ; EFSA, 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.
