致病性

Ten 10-day-old artificially-reared coccidian-free goslings were inoculated orally with 2.0×105-6.5×105 of sporulated oocysts of Eimeria stigmosa,respectively, and killed at intervals from 48th h to 180th h post-inoculation.

给10只10日龄雏鹅分别经口接种2.0×105~6.5×105个多斑艾美球虫孢子化卵囊，在接种后48~180h分期剖杀，对多斑艾美球虫的生活史和致病性进行了动态观察。

So the above-mentioned methods can be used to detect and screen pathogenic Vibrios rapidly,especially when the sample size is big or epidemic outbreaks.

因此，上述检测方法可用于重要致病性弧菌的快速检测及筛查，尤其是当样本量很大或者爆发疫情时。

This study will help us to identify the role of vhh/tlh haemolysin gene in the pathogenicity of vibrios.

对vhh/tlh溶血素基因在弧菌中的分布研究，将有助于进一步确定这类溶血素基因在病原弧菌致病性中的作用。

For five Enterobacteriaceaes tested for ESBLs by double-disk method, two primers were designed and synthetized: TEM-1and SHV-1, ESBLs gene type was amplified, sequenced and analyzed by PCR; the minimal inhibitory concentrations of Cetiofur combined BLI-Tazobactam to the five Enterobacteriaceae according to different proportions were carried out with two fold dilution method.

对产生ESBLs的5株致病性大肠埃希氏菌，设计并合成TEM-1和是SHV-12对引物，用PCR方法进行了ESBLs的DNA扩增、测序和基因型分析；用试管二倍稀释法测定头孢噻呋与BLI-他唑巴坦钠以不同配比对产生ESBLs大肠埃希氏菌的最小抑菌浓度。
