Many tools used in small animal practice can be adapted for use with exotic mammals. For those veterinarians with a strong interest in exotic mammals, specific equipment and supply needs need to be taken under consideration. Initial investment need not be great to get started with special species, and as the practice develops more specialized equipment can be added. Starting with equipment that aids in patient husbandry, diagnostic sampling, and routine hospital medical and surgical care is very helpful in creating confidence and expertise with these species. As the practice case load grows more sophisticated, equipment can be added, allowing for better diagnostic workups, medical treatment, and surgical care. The right equipment for the right job makes for a more rewarding and efficient exotic mammal practice. The author describes equipment and products (Table 1) he routinely uses in his private practice, and has provided a list of available sources. Readers should keep in mind that this list is not all-inclusive, and that in many instances products discussed can be found from multiple veterinary distributors or vendors. The author does not promote or recommend one supplier or manufacturer over another. 相似文献

This article will introduce the reader to the necessary steps needed to build the foundation for an efficient special species emergency practice. With the incorporation of new species into a practice, a clinician must consider hospital preparation, as well as housing and food accommodations. The investment of new equipment and the alteration of existing equipment will help to make the integration of special species patients into a small animal practice a success. Many of the same principles and techniques used in small animal medicine can be applied to special species medicine with careful consideration of species-specific characteristics. The incorporation and success of treating special species patients will depend on the training of the entire hospital staff from restraint and handling to telephone triage. Finally, an emergency practice that is incorporating special species will also need to invest in some essential reference material to have on hand. 相似文献

Monocytes are important mediators of inflammatory processes and are in the focus of immunological studies. While the preparation of human monocytes is widely established, little is published on the isolation of porcine monocytes for experimental studies. The aim of this study is to establish a cost efficient method of preparing and culturing porcine monocytes of considerable purity and reasonable yield. In our method, we combined and modified different protocols of human monocyte preparation. The blood of a single pig is harvested and treated with EDTA to prevent coagulation. Peripheral blood mononuclear cells are obtained by a density gradient centrifugation using a Bicoll gradient and monocytes are harvested by culturing on serum-treated culture flasks, rinsing and tapping. A high yield is obtained by constant cooling of flasks and tubes. The purity of the culture is evaluated by the expression of CD14, using flow cytometry. Using this method, we reached a purity of 92.6 % (+/? 3.06 %). With this procedure, we established a reliable method to prepare and cultivate porcine monocytes which can be performed cost effectively and does not require special equipment. 相似文献

The main foundation to veterinary medicine is the availability of laboratory tests. These tests may be performed in-clinic or at diagnostic laboratories. In-clinic testing is advantageous in producing quick results, but demands sound technical ability, basic equipment,and access to some routine and special reagents. Laboratory-based testing can back up those routine techniques that mayor may not be available at the clinic level as well as provide specialized testing. The knowledge of commercially available diagnostic services is important as well as preparation and proper shipping of samples for accurate determinations. 相似文献

A variety of microorganisms, nutrients or toxins are generally intrude our body through mucosal tissues or skin, where equipment for both preventing their invasions and catching their information to activate internal immune systems for adapting surroundings is arranged. Among the equipment, cells in charge of innate immunity, particularly dendritic cells (DCs), having an excellent capacity for prompt recognition of invaded pathogens via toll-like receptors (TLRs) to alert B and T cells for establishing aquired/adaptive immunity by presenting their processed antigenic fragments, have been paid great attention. These TLR-activated, antigen captured DCs are divided into two groups; one is pathogen-retaining unit and the other is pathogen-controlling unit. The latter DCs present processed antigenic molecules from the pathogens to competent β T cells together with special containers, such as class I, class II MHC and CD1 to generate specific cellular immunity. The former two MHC molecules can present processed peptide antigens, whereas the last CD1 molecule can present glycolipid/lipid antigens. In contrast, B lymphocytes that captured antigens via their specific immunoglobulin (Ig) receptors present digested peptide fragments with their class II MHC to stimulate suitable CD4+ helper T cells which in turn secrete various cytokines to efficiently expand and maintain antibody production from that partner B cells to establish humoral immunity. These β T cells and antibodies, recognize either processed antigenic peptide or glycolipid fragments, and thus, identification of these epitopes enables us to generate artificial pathogen-specific vaccines. Based on the recent findings about precise mechanisms of antigen processing and presentation orchestrated at the surface compartment, future development of vaccines against various pathogens are discussed. 相似文献

In the present study, an immunochromatographic strip was developed for the serological detection of trichinellosis in swine. In the strip, the excretory-secretory (ES) antigens of Trichinella labelled with colloidal gold was used as the detector, and the staphylococcal protein A (SPA) and goat anti-ES antibody were blotted on the nitrocellulose membrane for the test and control lines, respectively. The evaluation of the strip was performed by comparing 60 clinical positive blood samples detected by the artificial digestion method with 46 serum samples from pigs infected with parasites other than Trichinella and 30 serum samples of parasite-free healthy pigs. The strip was shown to be of high specificity and sensitivity that were closely correlated with those of ELISA. Furthermore, the dipstick assay based on the strip is rapid (10 min) and easy to perform with no requirement of special skill, reagent or equipment. This suggests the immunochromatographic strip is an acceptable alternative to be used in clinical laboratories lacking specialized equipment as well as for field diagnosis. 相似文献

Hygienic and ecological risks connected with utilization of animal manures and biosolids in agriculture 总被引：2，自引：0，他引：2
In recent years the fate of human and animal pathogen microorganisms as a potential pollutant of the environment has been paid increased attention. Substantial quantities of these compounds and their metabolites are excreted, flushed down the drain, discarded as waste, or left over in animal feedlots. After passing to the sewer, several of these compounds are not adequately eliminated by the methods that are currently used in sewage treatment. Substantial quantities of biosolids and livestock manure end up on agricultural land. Effective sanitation of the environment, particularly of some of its special parts, which can be a source of spreading of diseases, plays an important role in prevention of infectious diseases. In this respect special attention should be paid to the disinfection of infected farm animal excrements. Sanitation of excrements should, on the one hand, ensure effective inhibition of infectious agents and, on the other hand, comply with the requirement of preserving the composition of the manure so it can be used in agricultural production. 相似文献

In this article, information is given on potential physical and health hazards in the steps of the silicone cold temperature method, often referred to as “S 10 Standard Method.” The main potential hazards related to plastination, as well as recommended measures to effectively avoid explosion and health hazards are discussed. Some specialty chemicals pose chronic health hazards. Exposure to these chemicals can be avoided by standard laboratory hygiene, that is wearing personal protective equipment like safety goggles and protective gloves. Inhalation hazard, for example when working at open dehydration containers or when opening a gas curing box, is preferentially avoided by the action of an appropriate ventilation system. Acetone is the standard solvent used for dehydration and defatting of the specimens to be plastinated. Like for other flammable liquids, explosion protection must be considered when handling acetone. The concentration of acetone vapour in the air must be kept below the lower explosion limit through appropriate room or workplace ventilation. Furthermore, all potential sources of ignition should be removed from the explosion hazard zone. If electrical devices need to be operated inside the explosion hazard zone, they need a special design and approval. The conditions covered by this approval can be found on the identification plate of the individual device. 相似文献

Operations for intestinal ischemia are frequently done by veterinarians. In equine surgery those conditions commonly producing ischemia are intussusception, volvulus, bowel obstructions, and incarcerated hernias. In an attempt to predict intraoperative bowel viability after the restoration of circulation, a variety of adjuvant methods have been investigated. There is little question that of the techniques currently available, sodium fluorescein injected intravenously approaches the ideal in predicting nonviability in humans and in most animal models. Furthermore, it is safe, takes little operating time, is inexpensive, and is ubiquitously available; in addition, the only special equipment needed is a long-wave ultraviolet lamp. Reliance on this method would seldom result in nonviable bowel being left in situ. Furthermore, the use of fluorescein would minimize the unnecessary resection of viable intestine and, thereby, minimize the postoperative nutritional problems that may occur, especially in equines. The report of Sullins et al questions the accuracy of the fluorescein technique in predicting viability and nonviability in horses and also raises the question as to whether the prediction of viability, after the restoration of intestinal blood flow, also predicts normal intestinal function. Further investigations will be needed to confirm or refute these observations. 相似文献
