人兽共患病(Zoonosos)是指人和脊椎动物由共同的病原体引起的,并在人与动物之间相互传播的一类疾病,曾译为人兽共患病、人畜共患病、人畜互通病等,但有人认为将Zoonosos一词译为人兽互传病更为恰当。目前全世界已证实的人兽共患病约250多种,其中100多种是公共卫生上的重要疾病,严重威胁着人畜健康,它对社会的发展,国家的富强,民族的兴衰均有一定影响。1985年世界卫生组织(WHO)公布人兽共患病90多种,其中猪病25种,禽病24种,牛、羊病26种,马病13种。人兽共患病在全球都有发生,尤其在文化、经济落后的国家和地区发生更为严重。我国现属发展中… 相似文献

一、人兽共患病形势严峻人兽共患病定义。在1959年,世界卫生组织(WHO)和粮农组织(FAO)专家委员会对人兽共患病下的定义是"在脊椎动物与人之间自然传播的疾病或感染"。1.人兽共患病的发生与流行。家养动物与野生动物的疾病传染给暴露人群,人群感染后,有些可能发生人传染人,导致发病或死亡,有些人群的感染发病还会再传染给动物,形成循环发病。2.世界形势引人注目。目前有1415种人类疾病的病 相似文献

猪囊虫病又名猪囊尾蚴病(俗称米星肉)，是由有钩绦虫的幼虫所引起的一种人兽共患寄生虫病。对人、猪危害极大，成为严重的公共卫生问题，所以囊虫病是我国肉品检验的重点之一。本病在永平县流行多年，且少数地方近年呈上升趋势，直接威胁着我县人民的身体健康和养猪业的发展。为了解我县猪囊虫病分布情况，进一步为该病的防治提供科学依据， 相似文献

人兽共患病是指脊椎动物与人类之间自然传播和感染的疾病。它是由病毒、细菌、立克次体、衣原体、支原体、螺旋体、真菌、原虫和蠕虫等病原体所引起的各种疾病的总称。目前,全世界已证实的人兽共患传染病和寄生病共有250多种,其中较为重为严重的有89种,我国已证实的人兽共患病约有90种。人兽共患病的分类方式,世界各国不尽相同,目前尚无统一的分类方法。从其病原、宿主、流行病学或病原的生活史等角度而有多种分类方法。人与动物共患的疾病,主要是传染病和寄生虫病这两大类。传染病是由病毒和细菌等病原体引起。当前最重要的人兽共患人兽传染病有狂犬病、炭疽病、布氏杆菌病、结核病、鼻疽、钩端螺旋体病、土拉杆菌病、沙门氏菌病、鹦鹉热、日本血吸虫病、日本乙型脑炎和流行性感冒等。人兽共患寄生虫病主要有囊虫病、旋毛虫病和肝片吸虫病等。 相似文献

应用电感耦合等离子-质谱技术(ICP-MS),建立饲料中钠、镁、铬、锰、铁、铜、锌、砷、硒、镉和铅等元素的测定方法。对饲料样品的前处理方法、仪器工作参数和11种元素标准曲线进行优化;并以加标回收、分析方法比对和重复测试说明方法的准确性和精密性。方法在0～1 000 ng/ml范围内线性良好,仪器检出限为0.557 7～5.072 ng/ml,具有良好的精密度,其回收率在88.1%～104.4%之间,相对标准偏差小于5.0%。同时与原子吸收和原子荧光方法进行比对,测定结果相近。所建立的方法简单、快速,可替代原子吸收和原子荧光方法测定饲料中的11种金属元素,为饲料的质量控制提供理想的元素分析方法。 相似文献

In experiment 1, 6 pregnant mares received a concentrate that contained a trace mineral premix that provided 14.3 mg Cu, 40 mg Zn, 28 mg Fe, 28 mg Mn, 0.08 mg Co, 0.16 mg I, and 0.16 mg Se/kg concentrate (group A). Seven mares received the same concentrate plus 502 mg Zn and 127 mg Cu once daily (group B). No differences (P > .05) in foal growth data, or Cu, Zn, and Fe concentrations of mare milk, mare serum, or foal serum were observed. In experiment 2, 6 pregnant mares received the same concentrate as group A (group C), and 8 mares received the same concentrate fortified with 4× the trace mineral premix (group D). Group C mares had higher serum Zn concentration at 1 day (P < 0.01) and 56 days (P < 0.04). Group C mares had higher milk Fe concentration at 28 days (P < .01), and group D mares had higher milk Cu concentration at 56 days (P < .01). Group C foals had higher serum Cu concentration at 14 days (P < .03). The results from this study provide no evidence to indicate that supplementing late gestating and lactating mares with higher dietary trace mineral levels than those recommended currently by NRC has any influence on foal growth and development, or on the Cu, Zn, and Fe concentrations of the mare milk, mare serum, or foal serum. 相似文献

Breed differences for weight (CW), height (CH), and condition score (CS) were estimated from records (n = 12,188) of 2- to 6-yr-old cows (n = 744) from Cycle IV of the U.S. Meat Animal Research Center's Germplasm Evaluation (GPE) Program. Cows were produced from mating Angus and Hereford dams to Angus, Hereford, Charolais, Shorthorn, Galloway, Longhorn, Nellore, Piedmontese, and Salers sires. Samples of Angus and Hereford sires were 1) reference sires born from 1962 through 1970 and 2) 1980s sires born in 1980 through 1987. The mixed model included cow age, season of measurement and their interactions, year of birth, pregnancy-lactation code (PL), and breedgroup as fixed effects for CW and CS. Analyses of weight adjusted for condition score included CS as a linear covariate. The model for CH excluded PL. Random effects were additive genetic and permanent environmental effects associated with the cow. Differences among breed groups were significant (P < 0.05) for all traits and were maintained through maturity with few interchanges in ranking. The order of F1 cows for weight was as follows: Charolais (506 to 635 kg for different ages), Shorthorn and Salers, reciprocal Hereford-Angus (HA) with 1980s sires, Nellore, HA with reference sires, Galloway, Piedmontese, and Longhorn (412 to 525 kg for different ages). Order for height was as follows: Nellore (136 to 140 cm), Charolais, Shorthorn, Salers, HA with 1980s sires, Piedmontese, Longhorn, Galloway and HA with reference sires (126 to 128 cm). Hereford and Angus cows with reference sires were generally lighter than those with 1980s sires. In general, breed differences for height followed those for weight except that F1 Nellore cows were tallest, which may in part be due to Bos taurus-Bos indicus heterosis for size. 相似文献
