A warning signal from the system which indicates high EC or EC ratio of a dairy cow is used to inform the milker to pay attention to the suspected cow. The detection thresholds of EC and ECR to determine whether a quarter or a dairy cow is infected with mastitis correspond with the criterion of SCC = 500×103 cells/ml for quarter foremilk of a dairy cow. The performance of online system for mastitis detection in dairy cows is evaluated with several methods, such as the detection thresholds, running analysis and discrimination analysis.

以分房乳 SCC 500 × 103 cells/ml 作为乳房炎感染与否的门槛值，由牛旁采样分房乳样的检测与分析，探讨影响牛乳 EC 大小的相关因素及其关系，如分房乳中的氯离子浓度、挤乳时间、挤乳前后及乳成份，利用变异数分析探究未感染与感染乳房炎的分房乳之间，其 EC 及 ECR 物理性质，SCC、乳酸去氢酵素及 pH 化学性质及乳脂率、蛋白质及乳糖等乳成份的差异，进而利用统计鉴别分析探讨 EC 相关参数结合乳成份参数对乳房炎检测的准确度。

Recombinant plasmid pSVH 7 DNA of avian influenza virus H7 subtype heamagglutinin gene was encapsulated with DC-chol/DOPE liposomes and PC/chol/SA liposomes separately. Two-week old SPF chickens were intramuscularly inoculated with 50 μ g/0.2ml of the liposome entrapped PSVH 7 DNA. Four-weeks later, each chicken was challenged with 0.1ml 〓 AIV . One week after the challenge, the secretion of the cloacas was collected and transfected to chicken embryos to isolate the virus. The virus was isolated from 6/6 of the control group, 1/6 of the naked DNA group, 1/6 of the PC/chol/SA entrapped DNA group and 0/6 of the DC-chol/DOPE liposome entrapped group. The HI antibody titers (log2) of the four groups were 6. 83±0.98, 7. 0±1. 26, 7. 83±1. 17 and 8. 00±0.89 respectively 1-week after challenge, and 8. 5±0.55, 8. 17±0.82, 8. 68±0.45 and 9. 33±0.54 respectively 2-week after challenge. The results showed that inoculation of liposome entrapped DNA significantly enhanced resistance to virosis in animals.

将含禽流感病毒H7亚型血凝素基因的重组质粒pSVH7用DC-chol阳离子脂质体和胆固醇／卵磷脂／十八胺脂质体包裹，免疫2周龄SPF鸡，4周后用同型禽流感病毒进行人工感染，1周后采集泄殖腔分泌物分离病毒，结果未免疫组6／6分离到病毒，裸质粒DNA免疫组1／6分离到病毒胆固醇／卵磷脂／十八胺脂质体包裹DNA免疫组1／6分离到病毒，DC-chol脂质体DNA免疫组没有分离到病毒（0／6）：人工感染后1周各组的HI抗体（Log2）分别为6.38±0.98，7.00±1.26，7.83±1.17，8.00±0.89，2周后为8.50±0.55，8.67±0.82，8.68±0.45，9.33±0.52，脂质体包裹组在同期均高于未免疫组和裸DNA免疫组，表明脂质体包裹质粒DNA免疫动物后，能增加动物对病毒感染的抵抗力和反应能力。

RESULTS: Only one virus, A/Whooper swan/Mongolia/244/05, was able to infect mice after intragastric inoculation in liquid, whereas no evidence of infection was observed in ferrets after intragastric inoculation.

结果： 只有一种病毒(A/Whooper swan/244/05)在胃内液体接种后能感染小鼠，然而在雪貂胃内接种后未观测到感染的迹象。

The samples inhibited the binding of biotinylated lectins (from Canavalia ensiformis, Artocarpus integrifolia and Erythrina corallodendron, respectively) to microtitre plates with covalently bound carbohydrates (mannopyranoside, galactopyranoside and lactose, respectively).

将感染或未感染三代虫Gyrodactylus derjavini的虹鳟皮肤粘膜样品与甘露糖、半乳糖和乳糖反应以检测是否存在凝集素。

The four-week twice immunized hamsters acquired anti-MP in-fection capacity in local respiratory tract,as a result that swab culuturepositise was belove that of unimmunization group,and that only onehumster's lavage fluid culture was positive in immunization group.How-ever,unimmunization group positive rate of swabs and lavage fluid cul-ture was very high.This hinted that local respiratory tract's anti-MPinfection capacity was weak at the primary infection and the ability de-veloped gradually.4.The sIgA change in broncheal-lung lavage fluid.

而未免疫组咽拭子和支气管肺泡灌洗液MP分离培养的阳性均很高，说明在初次感染时，呼吸道局部防御清除MP的作用差，但随着时间的推移，其灌洗液培养的周次阳性率有下降趋势，MP培养的滴度亦随之降低，说明在感染以后随着时间的推移，呼吸道局部逐渐产生了防御、清除MP感染的作用。

The number of CD〓 and CD〓 lymphocytes subpopulation and IgA, IgM, IgG antibody-producing cells, the ratios of CD〓 and CD〓 T-cell in the cecal tonsils and Harderian glands, the content of IgA, IgM, IgG in tear, tracheal fluid, intestinal fluid and bile of CIAV-infected chicks vaccinated with ND vaccine were significantly decreased compared with vaccinated control chicks 7～28 days PV.

CIAV感染雏鸡ND免疫后28天内，哈德尔腺、盲肠扁桃体以及泪液、气管液、肠液、胆汁的上述各项免疫学指标，均不同程度的明显低于未感染CIAV的ND免疫雏鸡，表明CIAV感染雏鸡呼吸道和消化道局部粘膜对ND疫苗的细胞和体液免疫应答机能下降。

The RT-nPCR can be used to differentiate pigs infected with wild-type CSFV from those vaccinated with the C-strain vaccine. It thus minimizes the possibility of miss-killed vaccinates during outbreaks.
