The chapter describes some of the essential features of existing monitoring and surveillance programs in various countries around the world. It shows how these programs have been useful in improving understanding of resistance and its relation to antimicrobial use and other factors, guiding public policy, and measuring the impact of interventions on antimicrobial resistance in bacteria from animals, food, and humans. The major methodological considerations for the monitoring program include the types of samples to be collected, sampling strategies, species of bacteria, antimicrobials for susceptibility testing, data collection and analysis, and reporting of results. Comprehensive monitoring of antimicrobial resistance in animals in the context of animal and human health covers the entire farm-to-fork continuum. The Food and Drug Administration (FDA) Center for Veterinary Medicine (CVM) has been active in developing new approaches for the preapproval assessment of antimicrobial resistance risks from antimicrobials used in animals. The Japanese Veterinary Antimicrobial Resistance Monitoring (JVARM) program examines the susceptibility of bacteria from food-producing animals to antimicrobial agents. Most programs focus on pathogenic bacteria or Salmonella, but some also report data on resistance in indicator bacteria isolated from healthy animals. Knowledge about antimicrobial resistance should be combined with knowledge regarding the usage of antimicrobial agents for different food animal species, which also should be performed on an internationally comparable basis.","PeriodicalId":367474,"journal":{"name":"Antimicrobial Resistance in Bacteria of Animal Origin","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124817294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aminoglycosides exhibit rapid and significant bactericidal effects in vitro and should initially be included for the treatment of Campylobacter bacteremia in patients who appear very ill. The only mechanism of chloramphenicol resistance identified in Campylobacter occurs through modification of chloramphenicol by chloramphenicol acetyltransferase, which prevents its binding to the ribosome. The majority of contacts between Tet(O) and the ribosome are mediated by the rRNA, and one interaction with ribosomal protein S12. Most of the antimicrobials used in veterinary medicine are tetracyclines and macrolides, which result in high and continuous selective pressure for the animal-colonizing bacteria, ultimately resulting in the acquisition of antimicrobial resistance genes. Investigation into the mechanisms of action of antimicrobials, as well as the transfer of resistance determinants, is necessary to gain effective control of antimicrobial resistance. Epidemiological and microbiological studies show that poultry is the most important source for quinolone-susceptible and quinolone-resistant Campylobacter infections in humans. Trends over time for macrolide resistance show stable low rates in most countries, and macrolides should remain the drug class of choice for C. jejuni and C. coli enteritis.","PeriodicalId":367474,"journal":{"name":"Antimicrobial Resistance in Bacteria of Animal Origin","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114972904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most of the available data on specific antimicrobial resistance relate to Clostridium perfringens type A, causing necrotic enteritis in broiler chickens, and to Brachyspira hyodysenteriae, causing swine dysentery. Some Clostridium species are essentially nonpathogenic; others, such as C. perfringens, may act as opportunistic pathogens, occasionally causing disease; and others are classified as major pathogens. Recently, in vitro development of resistance to coumermycin A1 in B. hyodysenteriae was reported. The resistance was associated with single-nucleotide mutations in the gyr(B) gene. Coumarins are not used for treatment of infections with Brachyspira spp. and this study was performed to evaluate this resistance as a selective marker for genetic studies. Recently, three different mutations in the ribosomal protein L3 gene and six mutations in the 23S rRNA gene that are associated with tiamulin resistance in B. hyodysenteriae and B. pilosicoli were described. Early studies on the in vitro susceptibility of 18 U.S. strains of D. nodosus indicated that penicillin was the most effective antimicrobial, followed by cefamandole, clindamycin, tetracycline, chloramphenicol, erythromycin, cefoxitin, tylosin, nitrofurazone, tinidazole, and dihydrostreptomycin.","PeriodicalId":367474,"journal":{"name":"Antimicrobial Resistance in Bacteria of Animal Origin","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116326968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this report, the devastating effect of acquired sulfonamide resistance in the treatment of furunculosis was demonstrated in clinical trials. A. salmonicida strains from Norway, including 10 isolates of sulfonamide-resistant atypical strains representing the various groups of a typical A. salmonicida isolated in Norway, were screened for occurrence of class 1 integrons and sulfonamide resistance genes. In this study A. salmonicida isolates from Switzerland, Finland, France, Japan, Scotland, and the United States were also studied. The study also characterized a third R plasmid of about 70 kb found in two A. hydrophila isolates in 1974 in the United States. It is also of particular interest that one of the R plasmids of E. tarda is very similar to the R plasmids of P. damselae subsp. piscicida. Infections with multiple-drug-resistant V. anguillarum occurred in farmed ayu in Japan in 1973. Several studies demonstrate transfer of R plasmids from fish pathogens to E. coli recipients. In many ways, fish pathogens represent possible intermediate vectors for shipping antibiotic resistance genes between the environment and human beings for further recombination.","PeriodicalId":367474,"journal":{"name":"Antimicrobial Resistance in Bacteria of Animal Origin","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115360911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
