dc.description	The consumption of pork and beef has been directly related to reports of human cases caused by C. coli and C. jejuni, with a 47% association of this bacterium in pork and 35% in beef. Beef and pork are natural hosts and an essential source of contamination in humans. Gonzalez et al. (2019) states that several studies on the behavior of Campylobacter spp. to different antimicrobials have represented an interest of many researchers in some South American countries, which have evidenced strains of animal and human origin, with sensitivity to erythromycin, tetracycline, gentamicin, ampicillin, ciprofloxacin and quinolones, reaching rates above 90 %. The objective of this bibliographical study is to investigate the determination of antimicrobial susceptibility in C. jejuni and C. coli strains isolated from beef cattle and pork, through a review of scientific literature. At present, based on the evidence found in the bibliographical study of this document, it is emphasized that there are strains of C. jejuni and C. coli isolated from beef cattle and pigs that are sensitive to various antimicrobials such as: erythromycin, tetracycline, ampicillin, ciprofloxacin and quinolones. The use of fluoroquinolones and macrolides in animal production has a wide potential to select sensitive strains of Campylobacter spp. which allows the detection of new strains or clones. The sensitivity of Campylobacter spp. to aminoglycoside antimicrobials is high, especially in strains isolated from cattle and pigs. In cattle and swine production, gentamicin is indicated for the treatment of extraintestinal diseases due to Campylobacter spp. strains. The low levels of resistance of Campylobacter spp. strains isolated from beef cattle and swine is due to the way antimicrobials are used in animal production.	es_ES

dc.description.abstract	El consumo de carne de cerdo y ganado bovino, se ha relacionado directamente con reportes en casos humanos provocados por C. coli y C. jejuni, existiendo un 47 % de asociación de esta bacteria en carne de cerdo y en carne de vacuno un 35 %. La carne de bovino y carne de cerdo, son huéspedes naturales y una fuente esencial de contaminación en los seres humanos. González et al (2019) manifiesta que diversos estudios sobre el comportamiento de Campylobacter spp., a diferentes antimicrobianos ha representado un interés de muchos investigadores en algunos países sudamericanos, lo mismos que han puesto en evidencia cepas de origen animal y humano, con sensibilidad a eritromicina, tetraciclina, gentamicina, ampicilina, ciprofloxacino y quinolonas, alcanzando tasas superiores al 90 %. El objetivo de este estudio bibliográfico es investigar sobre la determinación de la sensibilidad antimicrobiana en cepas de C. jejuni y C. coli aisladas de bovinos de carne y cerdo, por medio de una revisión de literatura científica. En la actualidad con base a las evidencias encontradas en el estudio bibliográfico del presente documento recalca que existen cepas de C. jejuni y C. coli aisladas de bovinos de carne y cerdos sensibles a diversos antimicrobianos tales como: eritromicina, tetraciclina, ampicilina, ciprofloxacina y quinolonas. La utilización de fluoroquinolonas y macrólidos en la producción animal presentan un potencial amplio para seleccionar cepas sensibles de Campylobacter spp. lo que permite detectar nuevas cepas o clones. La sensibilidad de Campylobacter spp., a los antimicrobianos aminoglucósidos es alta, especialmente en cepas aisladas desde bovinos y cerdos. En la producción de ganado bovino y cerdos la gentamicina está indicada para el tratamiento de enfermedades extraintestinales debido a cepas de Campylobacter spp. Los bajos niveles de resistencia de cepas de Campylobacter spp., aisladas desde bovinos de carne y cerdos se debe a la forma de utilización de antimicrobianos en la producción animal.	es_ES
