Occurrence of CR E. coli was extremely variable among farms. Pigs were more likely to be positive at slaughter if they were positive as piglets. Shedding of CR E. coli increased with the treatment and decreased with the age. Abstract. CRESA_CAT 17/08/16 The use of antibiotics in pig farms may endanger public health? Study of the emergence of resistance. One of the negative consequences of the extensive use of antimicrobials in human and veterinary medicine is the appearance of bacteria resistant to antimicrobials.
In those cases of severe infections, or when the patient suffers immune depression, the presence of antimicrobial resistant bacteria can increase the morbidity or mortality of the patient. For this reason, the World Health Organization (WHO) has classified some antimicrobial drugs as critically important in human medicine, since they are the last option to treat some infectious diseases. Third generation cephalosporin and macrolides are some of these antimicrobials. Additionally, the majority of the antimicrobials used in veterinary medicine are structurally similar to those used to treat human infections. Therefore, the emergence of antimicrobial resistant bacteria in livestock may pose a risk to human health if resistant bacteria reaches the consumer via the food chain.
Journal of Antimicrobial Chemotherapy Advance Access published June 7, 2014 Characterization of extended-spectrum b-lactamase (ESBL)-producing Escherichia coli obtained from Danish pigs, pig farmers and their families from farms with high or no consumptio. IRTA 10/06/15 Transitory emergence of cephalosporin resistant E. coli is associated with beta-lactams treatments in pigs. A recently published study describes that the treatment of pigs with ceftiofur and amoxicillin are associated with the emergence of cephalosporin resistant (CR) E. coli during the course of the treatment.
This collaborative study was carried out by researchers of CReSA (IRTA-UAB), Universidad Complutense de Madrid and Universitat de Lleida. Dr. Migura, researcher of CReSA, briefly explains: “The study showed that both treatments generate an increase in the prevalence of CR E. coli during the treatment period, but resistance diminished after treatment and by the time of finishing, CR E. coli bacteria was not recovered from the animals”. The study was designed as follows. One hundred 7-day-old piglets were divided into two groups, a control group and a group parenterally treated with ceftiofur. The results suggest that the use of ceftiofur and amoxicillin at different stages of the rearing cycle are independent risk factors for the selection of CR E. coli.
PIG PROGRESS 12/08/11 Cephalosporin antibiotics: Control or ban? The Panel of Biological Hazards (BIOHAZ) of EFSA has just published an opinion on the public health risks of bacterial strains (primarily E. coli and Salmonella species) producing extended-spectrum beta-lactamase (ESBL) enzymes or AmpC beta lactamases in food producing animals and food.
These enzymes cause resistance to 3rd and 4th generation cephalosporins, such as ceftiofur and cefquinome and are thought to be associated with their use in veterinary medicine. Similar antibiotics are of critical importance in human medicine, hence the concern of the spread of the resistance genes that produce these enzymes from animals to man. They are looking at possible control options i.e. to stop all uses of cephalosporins, systemically active cephalosporins (not those used for mastitis control), or systemically active 3rd and 4th generation cephalosporins only or to severely restrict their use.

Abstract Introduction Fecal Escherichia coli isolates showing a phenotype of reduced susceptibility or resistance to extended-spectrum cephalosporins are common among pigs in Spain.
The aim of this study was to describe the main beta-lactam resistance mechanisms carried by these strains and their distribution at farm-level. Materials and methods.

ALLIANCE PORCI D'OC 28/04/11 Antibiorésistance: moratoire sur les Céphalosporines en élevages de porcs.
Mardi 26 avril 2011 2 26 / 04 / Avr / 2011 18:12 Les représentants de la filière porcine (Coop de France, FNP, INAPORC) ont décidé la mise en oeuvre d'un moratoire (suspension volontaire et provisoire de l'utilisation d'un produit vétérinaire) sur l'utilisation des antibiotiques de type céphalosporine de 3è et 4è génération (C3-4G : ceftiofur, cefquinome) en élevage de porcs. Ce moratoire s'appliquera à compter du 1er mai 2011 pour une durée de 2 ans.
La mise en place de ce dispositif s'appuiera notamment sur le suivi de l'évolution des consommations des céphalosporines et des pratiques d'élevage. Ces actions seront conduites en partenariat et en totale harmonie avec les organisations vétérinaires (AVPO, AFMVP, SNGTV). La mise en oeuvre de ce moratoire fait suite à plusieurs constats: Nécessité de préserver l'efficacité en santé humaine des derniers antibiotiques au point dont font partie les C3-4G,
