The literature on immunoprophylaxis as control method for ringworm in cattle is reviewed. Scientific papers on immune response to dermatophyte antigens and vaccination against ringworm were obtained from personal files and computerized search in 4 relevant databases. Vaccines with antigens of Trichophyton verrucosum stimulate a humoral and cellular immune response. In animals vaccinated with inactivated vaccines, some protection is observed after challenge. However, the protective immunity is inadequate in most cases. Vaccination with live vaccines elicits an immune response that prevents the development of clinical disease. The protective immunity is based mainly on the cellular branch of the immune system. The efficacy and safety of live dermatophyte vaccines have been demonstrated in both challenge experiments and field trials from different countries. Effective control of ringworm in cattle has been achieved in regions implementing systematic vaccination. 相似文献

An account is given of the present international position in immunoprophylactic control of Marek's disease. An assessment is made of the method used for immunisation in the GDR. In that context, reference is made to problems for which solutions will have to be found in the long run. 相似文献

Neoplasms arising from vascular endothelial cells include benign haemangioma and malignant haemangiosarcoma, both of which are rare in the horse. Haemangiosarcoma can arise as a solitary mass, typically involving the eye or skin, or as disseminated tumours throughout multiple organs. There is no sex, breed or age predilection but most cases are found in middle aged horses. Clinical presentations of haemangiosarcoma in the horse include the presence of a visible mass or reflect dysfunction of the organ involved, thus making it difficult to differentiate from other neoplasms. Ante mortem diagnosis through clinicopathological findings, cytological findings of body cavity effusions or fine needle aspirates are often unrewarding. Biopsy or mass submission for histopathological examination may aid in diagnosis of haemangiosarcoma. A majority of cases are diagnosed post mortem; however, if the mass is poorly differentiated additional diagnostics such as immunohistochemical staining may be needed. Unfortunately, treatment of haemangiosarcoma is often unrewarding and limited based on the location of the mass and the aggressive nature of this neoplasm. 相似文献

Monorchidism in the horse 总被引:1,自引:0,他引:1
Six horses with monorchidism, identified at surgery for cryptorchidectomy, are reported. All six presented with a single scrotal testis. Following surgical removal of one testis, they were either hormonally, anatomically or behaviourally determined to be geldings. Three other horses reported in the literature are reviewed. Of these nine cases of monorchidism, eight were thought to be caused by testicular degeneration and one by testicular agenesis. The vaginal process was present in all of the former and absent in the latter. The left side was involved in five of these eight horses. In seven, the epididymis was absent and, in the remaining two, only the epididymal tail was present. The condition was thought to be congenital in the six horses in this series. A surgical approach to identify accurately monorchid horses is described. 相似文献
