beta-Lactams are among the most clinically important antimicrobials in both human and veterinary medicine. Bacterial resistance to beta-lactams has been increasingly observed in bacteria, including those of animal origin. The mechanisms of beta-lactam resistance include inaccessibility of the drugs to their target, target alterations and/or inactivation of the drugs by beta-lactamases. The latter contributes predominantly to beta-lactam resistance in Gram-negative bacteria. A variety of beta-lactamases have been identified in bacteria derived from food-producing and companion animals and may further serve as a reservoir for beta-lactamase-producing bacteria in humans. While this review mainly describes beta-lactamases from animal-derived Escherichia coli and Salmonella spp., beta-lactamases from animal-derived Campylobacter spp., Enterococcus spp., Staphylococcus spp. and other pathogens are also discussed. Of particular concern are the increasingly-isolated plasmid-encoded AmpC-type CMY and extended-spectrum CTX-M beta-lactamases, which mediate acquired resistance to extended-spectrum beta-lactams. The genes encoding these enzymes often coexist with other antimicrobial resistance determinants and can also be associated with transposons/integrons, increasing the potential enrichment of multidrug resistant bacteria by multiple antimicrobial agents as well as dissemination of the resistance determinants among bacterial species. Characterization of beta-lactam-resistant animal-derived bacteria warrants further investigation of the type and distribution of beta-lactamases in bacteria of animal origin and their potential impact on human medicine. 相似文献

Salmonella is a member of the Salmonella family of Enterobacteriaceae and has about 2 600 different serotypes. As a widely distributed conditional pathogen,it has a serious impact on animal health, public safety and food safety.Pathogenic Salmonella can cause paratyphoid fever, pullorosis, avian typhoid and avian paratyphoid, non-pathogenic Salmonella may cause the contamination of animal-derived food. With the rapid development of aquaculture in recent years, the adverse effects of Salmonella to livestock and poultry breeding industry is more and more terrible.Antibiotic resistance of Salmonella resulting from abuse of antimicrobial agents is becoming more serious,thereby increasing the difficulty of Salmonella control. In this paper, Salmonella clinical diagnosis, laboratory diagnosis, the problems of prevention and treatment were reviewed in order to provide a reference for the improvement of salmonellosis prevention and control of livestock and poultry. 相似文献

沙门氏菌为肠杆菌科沙门氏菌属成员,具有约2 600种血清型,其在自然界中十分普遍,是一种条件致病菌,对畜禽健康、人类公共安全、食品安全都有严重的影响。近年来,随着养殖业的迅速发展,沙门氏菌对畜禽养殖业的影响越来越严重。实际生产中的抗生素滥用导致沙门氏菌的耐药状况愈发严重,致病性沙门氏菌可引起猪副伤寒、鸡白痢、禽伤寒、禽副伤寒等畜禽疾病,非致病性沙门氏菌可能造成动物源性食品的污染,加大了防制的难度。作者主要从沙门氏菌临床诊断、实验室诊断及预防和治疗中存在的问题进行了综述,以期为畜禽沙门氏菌病防制措施的改进提供参考依据。 相似文献

The application of antimicrobial agents has proved to be the main risk factor for development, selection and spread of antimicrobial resistance. This link applies to the use of antimicrobial agents in human and in veterinary medicine. Furthermore, antimicrobial-resistant bacteria and resistant genes can be transmitted from animals to humans either by direct contact or via the food chain. In this context, risk management has to be discussed regarding prevention and control of the already existing antimicrobial resistance. One of the primary risk management measures in order to control the development and spread of antimicrobial resistances is by regulating the use of antimicrobial agents and subjecting their use to guidelines. Thereby, the occurrence of antimicrobial resistant bacteria in the human and veterinary habitat can be controlled to a certain degree. There is little information about past attempts to prevent the development of resistances or to control them, and even less is known about the effectiveness or the cost intensiveness of such efforts. Most of the strategies focus on preventing and controlling antimicrobial resistance by means of the reduction or limitation of the use of antimicrobial agents in food-producing animals. 相似文献

The vast literature on antimicrobial drug use in animals has expanded considerably recently as the antimicrobial resistance (AMR) crisis in human medicine leads to questions about all usage of antimicrobial drugs, including long-term usage in intensively managed food animals for growth promotion and disease prevention. Attention is also increasingly focusing on antimicrobial use and on bacterial resistance in companion animals, which are in intimate contact with the human population. They may share resistant bacteria with their owners, amplify resistant bacteria acquired from their owners, and act as a reservoir for human infection. Considerable effort is being made to describe the basis of AMR in bacterial pathogens of animals. Documentation of many aspects of use of antimicrobials in animals is, however, generally less developed and only a few countries can describe quantities of drugs used in animals to kg levels annually. In recent years, many national veterinary associations have produced 'prudent use guidelines' to try to improve antimicrobial drug use and decrease resistance, but the impact of guidelines is unknown. Within the evolving global movement for 'antimicrobial stewardship', there is considerable scope to improve many aspects of antimicrobial use in animals, including infection control and reduction of use, with a view to reducing resistance and its spread, and to preserving antimicrobial drugs for the future. 相似文献
