畜禽寄生虫病的种类很多,分布广泛,常以隐蔽的方式危害动物的健康,不仅影响幼龄畜禽的生长发育,降低生产性能和产品质量,而且还可引起大批动物的死亡,造成巨大的经济损失,给畜牧业的发展带来严重危害。有很多家畜寄生虫病是人畜共患的疾病,其病原体往往也感染人,并引起人类发生严重的疾病,甚至造成死亡。因此,畜禽寄生虫病的防治,必须贯彻以"预防为主,防重于治"的方针,根据当地寄生虫病的流行情况及在当地寄生虫区系调查的基础上,制定出切实可行的防治措施,进行综合防制。针对当前畜禽寄生虫病现状,结合多年的实践工作经验,就寄生虫病的防治提出见解,对预防和控制畜禽寄生虫病具有临床指导意义。 相似文献

牛寄生虫病不仅可以降低牛的抗病能力,还会出现大范围传染现象,一旦饲养牛群中有牛只感染寄生虫将会对整个牛群产生不利影响。基于此,饲养人员需要适时对牛主要寄生虫病进行防治。笔者根据多年工作经验,对牛主要寄生虫病的病发机理以及对牛身体健康的影响进行总结,并从实际情况出发,论述了牛主要寄生虫病的防治措施。 相似文献

Among the representatives of the class aves, ocular lesions may be a particularly strong indicator of systemic disorders. A causative diagnosis of ocular lesions may be vital for the avian patient, not only as a basis for effective therapy of the primary disease, but also for saving the vision, as birds orientate themselves primarily by vision. The following paper presents a synopsis of important ocular disorders in avian patients that are either pathognomonic for certain disorders or, when considered in conjunction with other organic diseases, enable a specific diagnosis. Bacterial and parasitic infections were already described in part 1 of this paper. Part 2 gives outlines of possible viral etiologies and noninfectious diseases. 相似文献

Proliferative kidney disease (PKD) is an immunopathological condition of salmonid fish, caused by the hyperplastic response of their principal lymphoid tissues to infection with the spores of Tetracapsula bryosalmonae , a myxozoan parasite formerly designated proliferative kidney organism – unknown (PKX). In order to investigate the nature of cells involved in this host response and possible alterations of their functions during parasitic infection the course of PKD was studied by flow cytometry (FCM) techniques, using blood, pronephros and spleen leucocyte populations from rainbow trout infected by intraperitoneal (i.p.) injection with parasitic cells from infected donor fish. The parameters of the cellullar response studied were: cytogram of cell population, lymphoproliferation, phagocytosis, oxidative burst, and non-specific cytotoxicity. The modifications of cell population distribution and function in the PKD-infected fish mainly affected the pronephros cell populations and were coincident with the clinical phase of disease. During this phase, the lymphocytes constituted the major leucocyte cell population and underwent proliferation and were thus responsible for the renal tissue hyperplasia. Meanwhile, phagocytosis and oxidative burst were depressed. These data are in agreement with the patho-epidemiological background of PKD where the enhancement of the fish sensitivity to bacterial infections reflects the impairment of certain cellular defence mechanisms of innate immunity. 相似文献

Tuberculosis is still important as a disease of birds kept as pets and in zoos, and as a zoonosis. In living birds the diagnosis is difficult. In combination with the clinical and laboratory examination, radiology may help to lead to the diagnosis "generalised mycobacterial infection". Eight cases of tuberculosis seen in the clinic of our institute showed the different radiographic signs which may occur in the course of a mycobacterial infection. The specificity of the x-rays in combination with clinical and laboratory results is discussed. 相似文献

Abstract. Eleven wild-caught dolphin fish ( Coryphaena hippurus L.) from Florida waters and 16 of the same species from an experimental mariculture facility were examined for evidence of parasitic disease. Thirteen (48–1%) were found to be infected with parasites of the digestive tract. Adults of the digenean trematode Dinurus rornatus were present in the stomach and intestine. Invasive metacercarial stages of the same species were found encysted in the somatic musculature, pericardium and stomach wall. Metacercaria were associated with mild inflammatory cell infiltration of the musculature and gastric submucosa and, in one case, focal degeneration of the muscle fibres. In addition, invasive plerocercoidsof an unidentified cestode species occurred in the stomach and intestine of a moribund juvenile fish; the associated lesions included degeneration and ulceration of the gastric and intestinal mucosa, with haemorrhage and granuloma formation in submucosal tissues. These findings indicate that parasitic infection of the digestive tract can be a significant cause of disease in dolphin fish in Florida waters. 相似文献

In the Federal Republic of Germany the ownership of birds of prey and owls is subject to legal provisions for the conservation of nature and wildlife, as well as to the game law. Minimal requirements for housing and care of such birds result from regulations for animal welfare. According to these--arranged as to the pertinent paragraphs--recommendations are supplied for dealing with all aspects of animal welfare in the management and care of birds of prey and owls. 相似文献

Clinical diagnosis in companion birds consists of well established procedures such as case history, clinical observation, physical examination and further special investigations, e.g. radiology, endoscopy or clinical chemistry. Also some peculiarities of the numerous bird species have to be taken into consideration. These are, for example, certain characteristics of the different species, the varieties of husbandry and environment as single caged birds or flocks in zoos and aviaries and, especially, the lack of typical clinical symptoms in most cases. In regard to those aspects, case history concerning aspects such as age, sex, feeding or course of the disease and special investigations in the case of single caged birds and diagnostic dissections and etiological laboratory examinations, e.g. microbiology, parasitology and toxicology, in the case of flock problems are of major significance. Examples of differential diagnosis in single caged birds, e.g. abnormal behaviour ("feather plucking"), gout, intestinal foreign bodies, tumors or pneumomycosis, and flock health problems, e.g. acariasis, canary pox, coccidiosis or bacterial infections complete this paper. 相似文献
