1 寄生虫是如何侵入畜禽体内的? 当某一种或某几种寄生虫暂时或长久地寄生于畜禽体内或体表并引起相应的疾病,称为畜禽寄生虫病。寄生虫病是一种慢性侵袭性疾病,能使患病畜禽机体消瘦、代谢过程障碍、生产性能降低,最后因贫血或中毒或衰竭而死亡。那么,具有侵袭性的寄生虫或虫卵是如何侵入畜禽体内的呢?根据侵入的部 相似文献

Nematode parasites have been a major factor limiting sheep production in New Zealand for more than 100 years. Twenty-nine species of nematodes were unintentionally introduced with sheep into New Zealand, but it is principally species of Haemonchus, Ostertagia, Trichostrongylus, Nematodirus and Cooperia that are associated with production losses and clinical disease. The seasonal dynamics of nematode infection are the consequence of complex inter-relationships between the sheep, their husbandry and the prevailing climate. The patterns of pasture contamination by nematode eggs and then larvae, and the subsequent levels of infection in ewes and lambs are broadly similar throughout New Zealand. Numbers of infective larvae on pasture build up over summer to a peak in autumn/early winter with, in some years, a spring peak derived from the parturient rise in faecal nematode egg counts (FEC), expressed in eggs per gram of faeces (epg), in lactating ewes. The immune capability of lambs is initially low but increases with the magnitude and duration of exposure to infection. Once significant immunity has developed (usually by 10–12 months of age), sheep are capable of markedly restricting parasite infection, except during times of disease, malnutrition or stress. For the effective control of nematode parasites, farmers have come to rely almost exclusively on broad-spectrum anthelmintics. However, issues relating to resistance, residues and eco-toxicity increasingly threaten the sustainability of chemotherapy. In order to maintain present levels of parasite control and productivity in the long term, farmers need to integrate management practices aimed at minimising animal exposure to parasites with reduced reliance on anthelmintics. 相似文献

Biological control of parasitic nematodes of livestock is currently under development and represents another tool that may be integrated into helminth parasite control strategies. This paper presents a brief introduction to commercial sheep farming in South Africa and currently available nematode parasite control methods. These include the FAMACHA clinical assay, strategies of pasture management, dilution of resistant worm species by introduction of susceptible worms, breed resistant sheep and nutritional supplementation. The purpose of this paper is to outline the principles of biological control using nematophagous fungi and how it may be applied on sheep farms in South Africa. 相似文献

The faecal egg count reduction test (FECRT) was conducted on 39 sheep farms and 9 goat farms located in Peninsular Malaysia. The anthelmintic groups used in these tests were the benzimidazoles, levamisole, the benzimidazole/levamisole combination, macrocyclic lactones and closantel. Results indicated that the prevalence of resistance to the benzimidazole group was high, with approximately 50% of the sheep farms and 75% of the goat farms having resistant nematode parasite populations present. Resistance to levamisole, closantel and ivermectin was also detected. Differentiation of the infective larvae derived from faecal cultures indicated that by far the most predominant parasite species was Haemonchus contortus. 相似文献

Thirteen parasite species, three trematodes, five cestodes, one nematode, and four arthropods, have been reported in livestock in Asir, southwestern Saudi Arabia. The occurrence of Dicrocoelium dendriticum in imported sheep and Paramphistomum cervi in indigenous cattle is recorded for the first time in Saudi Arabia. 相似文献

为掌握青海省海北州藏羊群中牛病毒性腹泻病毒和羊边界病毒的感染情况,本研究采用RT-PCR方法分别对青海省海北州的161份健康藏羊血清样品和34份腹泻藏羊组织样品进行了BVDV和BDV的抗原核酸检测。结果显示:195份样品中BVDV和BDV总阳性率分别为29.74 %和14.36 %;161份健康藏羊血清样品中BVDV和BDV平均阳性率分别为26.71 %和11.80 %,BVDV/BDV混合感染率为4.35 %;34份腹泻藏羊组织样品中BVDV和BDV平均阳性率分别为44.12 %和26.47 %,BVDV/BDV混合感染率为17.65 %。本研究表明青海省海北州健康藏羊群和腹泻藏羊群中均存在BVDV、BDV的单独感染以及混合感染,且感染情况在个别养殖场(户)较为严重,本研究为青海藏羊的综合防控措施提供了指导依据,丰富了我国羊群中BVDV和BDV的流行病学资料。 相似文献

Nematodirus abnormalis is a common nematode parasite of sheep on several farms in the Caledon district of the south-western Cape and is the major species of Nematodirus on a farm in the Riviersonderend mountains of this region, yet it has never before been recorded from domestic animals in South Africa. 相似文献
