Hospitalization of sick animals tremendously increases their risk of acquiring infections as this congregates animals that are most likely to be shedding infectious agents with animals that often have enhanced susceptibility. In order to provide the best veterinary care possible, veterinarians have an underlying responsibility to minimize the risk of additional harm that might unintentionally befall a patient because of their interventions. This includes minimizing the risk of exposing patients to infectious agents. It is therefore incumbent upon veterinarians to actively manage the risk of nosocomial infections. Nosocomial infections in veterinary hospitals are not solely a patient-care concern; the spread of infectious agents can also significantly impact normal hospital operations, revenue, client confidence, public image, and can even affect the morale of hospital personnel. In some cases nosocomial agents can also be zoonotic. This paper discusses the need for biosecurity programs in veterinary practices, and describes a practical approach for developing biosecurity practices that are tailored to individual facilities.  相似文献

Because nosocomial and zoonotic diseases are inherent and ever-present risks in veterinary hospitals, proactive policies should be in place to reduce the risk of sporadic cases and outbreaks. Policies should ideally be put in place before disease issues arise, and policies should be effectively conveyed to all relevant personnel. Written policies are required for practical and liability reasons and should be reviewed regularly. Although no infection control program can eliminate disease concerns, proper implementation of barrier precautions and isolation can reduce the exposure of hospitalized animals and hospital personnel to infectious agents. Appropriate personal hygiene, particularly hand hygiene, can assist in the prevention of disease transmission when pathogens bypass barriers and are able to contact personnel. Veterinary hospitals have moral, professional, and legal requirements to provide a safe workplace and to reduce the risks to hospitalized patients. Based on experience in the human medical field and on the continual emergence of new infectious diseases, infection control challenges can only be expected to increase in the future. Regular reassessment of protocols based on ongoing research and clinical experiences is required.  相似文献

Veterinary practices are unique environments that bring humans into close contact with many different species of animals; therefore, the risk of exposure to infectious pathogens is inherently different in veterinary medicine than in human medicine. In contrast to the risk of exposure to blood in human medicine, infections from zoonotic diseases in veterinary personnel are primarily related to exposure to animal faeces, infected skin, wounds, droplets and puncture wounds. Infection-control measures in veterinary practices are often insufficient to prevent zoonotic disease transmission. The Veterinary Standard Precautions (VSP) Compendium is designed to help prevent transmission of zoonotic pathogens from animal patients to veterinary personnel in private practice.  相似文献

This study evaluated specific infection control practices in community veterinary practices in southern Ontario. Environmental disinfection, management of infectious patients and antimicrobial use in clean surgical procedures were investigated. Community companion animal veterinary practices (n = 101) in Southern Ontario were recruited, and a questionnaire was administered to one veterinarian and one veterinary technician from each practice. The veterinarian questionnaire gathered data on clinic demographics, management of infectious patients, infectious diseases of concern, environmental disinfection and antimicrobial use in surgical procedures. The veterinary technician questionnaire gathered data on environmental disinfection. None of the veterinary practices had a formal infection control programme. Sixty‐five per cent (n = 66) of the veterinary practices did not have an isolation area and 61% (n = 40) of these practices did not employ any specific infection control measures for infectious cases. The products most frequently used for environmental disinfection were hydrogen peroxide based or quaternary ammonium compounds. Bleach was the agent most commonly used for environmental disinfection of infectious body fluids; however 60% of the veterinarians and 40% of the veterinary technicians did not identify a product for environmental disinfection of infectious body fluids. Twenty‐four per cent of the veterinarians reported using antimicrobials in animals undergoing elective sterilization surgeries and 60% reported using antimicrobials in other clean surgical procedures. There is a need for community veterinary practices to develop infection control programmes specific to their individual practice. In addition, veterinarians should discontinue the common use of antimicrobials for clean elective sterilization surgical procedures.  相似文献

Mycobacterial infections in equids are relatively rare but the case report (Charlesworth 2017) detailed in this issue highlights that Mycobacterium bovis infections may still result in clinical signs in this incidental host and have zoonotic potential. Most reported cases of M. bovis in horses have a protracted disease course, with features including pyrexia, weight loss and oedema with a nonspecific inflammatory profile. As such, the clinical features of disease overlap with conditions such as neoplasia, peritonitis, protein‐losing enteropathies and bacterial infections including Rhodococcus equi and Lawsonia intracellularis. In this clinical satellite article, mycobacterial infections in equids are considered in terms of incidence and mode of transmission, key clinical features and perhaps most importantly, in terms of the diagnostic techniques that can be used in order to reach a definitive (ante mortem) diagnosis. The major zoonotic risk to veterinary personnel is likely to occur at the time of post‐mortem examination of infected horses, and awareness of these potential risks remains of the utmost importance.  相似文献

Nosocomial infections and antimicrobial resistance are topics that have been intensely studied in human medicine because of their significant impact on human health. In recent years, concerns have been raised that the use of antibiotics in veterinary medicine, animal husbandry, and agriculture may be contributing to the development of resistance in common bacterial species affecting human beings. Although there is inadequate proof at this time that the resistance is transmitted from animals to people, if antibiotics continue to be used indiscriminately in veterinary medicine, veterinarians may find themselves facing regulations restricting the use of some antibiotics. Nosocomial infections have been reported in veterinary medicine and are likely to increase in prevalence with the increase in intensive care practices in many hospitals. Prolonged hospitalization and the use of invasive devices and procedures increase the risk of nosocomial disease. As in human medicine, organisms isolated in the nosocomial infections reported in veterinary patients have an increasingly broad spectrum of antimicrobial resistance. Despite these findings, the use of empiric and prophylactic antibiotic therapy is still widespread in veterinary medicine. Nosocomial infections and antimicrobial resistance may have a serious impact on the future of [table: see text] veterinary medicine, because the cost and ability to treat our patients may be affected by the loss of access to or effectiveness of antimicrobial drugs. Despite the millions of dollars spent on research to reduce the incidence of nosocomial infections in human patients, the strategies that have consistently proven successful are simple and inexpensive to implement. The most important factor in preventing nosocomial infections is improving the hygiene practices of health care providers. Hand-washing or the use of disposable gloves can dramatically reduce the transmission of bacteria between patients. Aseptic technique should be used in the placement and management of all invasive devices. All staff members should be educated on the risks and symptoms associated with nosocomial infections so that cases can be detected early and treated appropriately. We in the veterinary profession have the opportunity to learn from the experiences of the human medical profession and can take steps to prevent the escalation of nosocomial infections and their impact on our profession.  相似文献

From the point of view of disease risk, the movement of livestock by embryo transfer is undoubtedly much safer for trading than the movement of live animals or semen. Nevertheless, strict governmental control by veterinary certification of health of embryos is still vital. In cattle, sheep and pigs, unlike laboratory species such as the mouse, infectious agents do not appear to pass through the zona pellucida (ZP) into the embryo proper. Some agents do, however, adhere firmly to the outer surface of the ZP, especially onto those of the pig. Disease risks associated with the inadvertent transmission of infectious agents when embryos are moved are, therefore, intimately connected with the nature and properties of the ZP. This article reviews current knowledge on the physical and adhesive properties of the ZP and discusses how risks associated with the possible presence of infection on its surface can be minimized. Further research is urgently needed so that realistic but safe veterinary certification of the health of embryos for international trade can be devised.  相似文献

Mycobacterium tuberculosis is the main cause of human tuberculosis. Infection in companion animals is mainly acquired from close contact to a diseased human patient and hence rarely diagnosed in countries with low tuberculosis incidence rates. Therefore the general awareness of the disease might be low. Here we report the potential risk of infection for veterinary personnel with M. tuberculosis during the clinical and pathological examination of a dog with unexpected disseminated tuberculosis. The dog had presented with symptoms of a central nervous system disease; rapid deterioration prevented a complete clinical workup, however. Post-mortem examination revealed systemic mycobacteriosis, and M. tuberculosis was identified by PCR amplification of DNA extracts from paraffin-embedded tissue sections and spoligotyping. Contact investigations among the owners and veterinary personnel using an IFN-γ release assay indicated that the index dog did not infect humans during its lifetime. Serological and IFN-γ release assay results of one of two cats in direct contact with the index dog, however, suggested that transmission of M. tuberculosis might have occurred. Importantly, all three pathologists performing the necropsy on the dog tested positive. Accidental infection was most likely due to inhalation of M. tuberculosis containing aerosols created by using an electric saw to open the brain cavity. As a consequence routine necropsy procedures have been adapted and a disease surveillance program, including tuberculosis, has been initiated. Our results highlight the importance of disease awareness and timely diagnosis of zoonotic infectious agents in optimizing work safety for veterinary personnel.  相似文献

Recent advances in molecular biology, genetics, and immunochemistry have provided the basis for a new generation of vaccines, diagnostic tools, and prophylactic substances for the prevention of infectious diseases in cattle. This article describes how these new technologies are being applied to veterinary medicine and their potential in bovine respiratory diseases caused by infectious agents.  相似文献
