Reproduction is authorised provided the source is acknowledged. Introduction On 6 February 2019, the European Commission sent a request to the European Medicines Agency (EMA) for a report on the criteria for the designation of antimicrobials to be reserved for the treatment of certain infections in humans in order to preserve the efficacy of those antimicrobials. The Agency was requested to provide a report by 31 October 2019 containing recommendations to the Commission as to which criteria should be used to determine those antimicrobials to be reserved for treatment of certain infections in humans (this is also referred to as ‘criteria for designating antimicrobials for human use’, ‘restricting antimicrobials to human use’, or ‘reserved for human use only’). The Committee for Medicinal Products for Veterinary Use (CVMP) formed an expert group to prepare the scientific report. The group was composed of seven experts selected from the European network of experts, on the basis of recommendations from the national competent authorities, one expert nominated from European Food Safety Authority (EFSA), one expert nominated by European Centre for Disease Prevention and Control (ECDC), one expert with expertise on human infectious diseases, and two Agency staff members with expertise on development of antimicrobial resistance . -

Effects of Chlortetracycline and Copper Supplementation on Levels of Antimicrobial Resistance in the Feces of Weaned Pigs
EFFECTS OF CHLORTETRACYCLINE AND COPPER SUPPLEMENTATION ON LEVELS OF ANTIMICROBIAL RESISTANCE IN THE FECES OF WEANED PIGS by GETAHUN EJETA AGGA DVM, Addis Ababa University, 2003 MSc, Utrecht University, 2008 AN ABSTRACT OF A DISSERTATION submitted in partial fulfillment of the requirements for the degree DOCTOR OF PHILOSOPHY Department of Diagnostic Medicine/Pathobiology College of Veterinary Medicine KANSAS STATE UNIVERSITY Manhattan, Kansas 2013 Abstract The use of antibiotics in food animals is of major concern as a purported cause of antimicrobial resistance (AMR) in human pathogens; as a result, alternatives to in-feed antibiotics such as heavy metals have been proposed. The effect of copper and CTC supplementation in weaned pigs on AMR in the gut microbiota was evaluated. Four treatment groups: control, copper, chlortetracycline (CTC), and copper plus CTC were randomly allocated to 32 pens with five pigs per pen. Fecal samples (n = 576) were collected weekly from three pigs per pen over six weeks and two Escherichia coli isolates per sample were tested phenotypically for antimicrobial and copper susceptibilities and genotypically for the presence of tetracycline (tet), copper (pcoD) and ceftiofur (blaCMY-2) resistance genes. CTC-supplementation significantly increased tetracycline resistance and susceptibility to copper when compared with the control group. Copper supplementation decreased resistance to most of the antibiotics, including cephalosporins, over all treatment periods. However, copper supplementation did not affect minimum inhibitory concentrations of copper or detection of pcoD. While tetA and blaCMY-2 genes were associated with a higher multi-drug resistance (MDR), tetB and pcoD were associated with lower MDR. Supplementations of CTC or copper alone were associated with increased tetB prevalence; however, their combination was paradoxically associated with reduced prevalence. -

Statistical Analysis Plan / Data Specifications the Risk of Acute Liver Injury Associated with the Use of Antibiotics. a Replica
WP6 validation on methods involving an extended audience Statistical analysis plan / data specifications The risk of acute liver injury associated with the use of antibiotics. A replication study in the Utrecht Patient Oriented Database Version: July 11, 2013 Authors: Renate Udo, Marie L De Bruin Reviewers: Work package 6 members (David Irvine, Stephany Tcherny-Lessenot) 1 1. Context The study described in this protocol is performed within the framework of PROTECT (Pharmacoepidemiological Research on Outcomes of Therapeutics by a European ConsorTium). The overall objective of PROTECT is to strengthen the monitoring of the benefit-risk of medicines in Europe. Work package 6 “validation on methods involving an extended audience” aims to test the transferability/feasibility of methods developed in other WPs (in particular WP2 and WP5) in a range of data sources owned or managed by Consortium Partners or members of the Extended Audience. The specific aims of this study within WP6 are: to evaluate the external validity of the study protocol on the risk of acute liver injury associated with the use of antibiotics by replicating the study protocol in another database, to study the impact of case validation on the effect estimate for the association between antibiotic exposure and acute liver injury. Of the selected drug-adverse event pairs selected in PROTECT, this study will concentrate on the association between antibiotic use and acute liver injury. On this topic, two sub-studies are performed: a descriptive/outcome validation study and an association study. The descriptive/outcome validation study has been conducted within the Utrecht Patient Oriented Database (UPOD). -
