猪传染性胃肠炎的中草药治疗

猪传染性胃肠炎是一种由传染性胃肠炎病毒侵染猪只肠道所引起的高接触性传染性疾病。该病临床表征以患畜腹泻、呕吐、脱水等为主。临床治疗实践表明,中草药对猪传染性胃肠炎具有良好疗效。对此,文章主要探讨猪传染性胃肠炎的中草药治疗方法,希望对猪传染性胃肠炎的防治提供一些有效借鉴。     

复方中草药对猪传染性胃肠炎的治疗研究

研究复方中草药对猪传染性胃肠炎的临床疗效,对复方中草药防治猪传染性胃肠炎的方法进行完善。选用复方中草药方剂"乌梅散"、"胃苓汤"、"白龙散"、"白头翁汤"分别对自然感染且具有明显猪传染性胃肠炎临床症状的患猪进行治疗,同时比较四种复方中草药预防猪传染性胃肠炎病的效果。发现"乌梅散"、"胃苓汤"、"白龙散"及"白头翁汤"经口服治疗治愈率分别为77.50%、62.50%、75.00%、50.00%;经口服预防未发病率为80.00%、70.00%、90.00%、40.00%,这表明复方中草药对于防治猪传染性胃肠炎有效,其中"乌梅散"的治疗效果较理想,"白龙散"的预防效果较好。复方中草药具有抗猪传染性胃肠炎的效果可以对该病进行防治,但临床预防效果高于治疗效果。

Inner structures of some coronaviruses.

When treated with formaldehyde, Tween 80, sodium oleate and Nonidet P-40, avian infectious bronchitis virus, porcine transmissible gastroenteritis virus, neonatal calf diarrhea coronavirus, porcine hemagglutinating encephalomyelitis virus as well as the human coronavirus show similar inner structures by negative staining. The first one is an inner membranous bag. This structure could be evaginated following treatments used and does not show the characteristic projections of coronaviruses. Subsequently, the inner fold could be separated from the outer membrane at the point of junction between these two membranes. Each virus does not react in the same way to the action of the different products. The transmissible gastroenteritis virus appears more sensitive to treatments than other viruses. On the other hand, the hemagglutinating encephalomyelitis virus is the most resistant. The variable sensitivities of these viruses are not related to the type of host-cells. Also, a second internal structure, which is more dense than the viral particle, encircles partially the aperture of the internal tongue-shaped structure and seems to emerge from the viral particle through the aperture of the inner bag.     

The interferon sensitivity of selected porcine viruses.

The objective of this study was to compare the sensitivity of 11 porcine viruses to the antiviral effects of porcine interferon-alpha in serum from piglets which had been infected 19 h previously with transmissible gastroenteritis virus, and of porcine interferon-beta prepared in PK-15 cells by induction with polyinosinic:polycytidylic acid, in yield reduction assays in pig kidney cells which were treated with interferon before virus challenge, and both before and after virus challenge. The most sensitive virus to both types of interferon was vesicular stomatitis. A porcine isolate of bovine herpesvirus type 1, hemagglutinating encephalomyelitis virus and porcine enterovirus types 1 and 2 were also highly sensitive to interferon-alpha. There was little reduction in the yield of porcine parvovirus or porcine rotavirus, while swinepox, swine influenza and transmissible gastroenteritis viruses were intermediate in their sensitivity to interferon-alpha. In addition to vesicular stomatitis virus, porcine adenovirus type 3, swine influenza, hemagglutinating encephalomyelitis and porcine rotavirus were highly sensitive to interferon-beta, while swinepox, bovine herpesvirus type 1, porcine parvovirus, transmissible gastroenteritis and porcine enteroviruses were less sensitive than the above viruses to interferon-beta, although all showed significant reductions in virus yield.     

Chicken egg yolk antibodies(IgY) as non-antibiotic production enhancers for use in swine production:a review

In recent years,the use of in-feed antibiotics for growth and disease prevention in livestock production has been under severe scrutiny.The use and misuse of in-feed antibiotics has led to problems with drug residues in animal products and increased bacterial resistance.Chicken egg yolk antibodies(IgY) have attracted considerable attention as an alternative to antibiotics to maintain swine health and performance.Oral administration of IgY possesses many advantages over mammalian IgG such as cost-effectiveness,convenience and high yield.This review presents an overview of the potential to use IgY immunotherapy for the prevention and treatment of swine diarrhea diseases and speculates on the future of IgY technology.Included are a review of the potential applications of IgY in the control of enteric infections of either bacterial or viral origin such as enterotoxigenic Escherichia coli,Salmonella spp.,rotavirus,porcine transmissible gastroenteritis virus,and porcine epidemic diarrhea virus.Some potential obstacles to the adoption of IgY technology are also discussed.
