With the increasing of stress and incensitive rearing, change of rearing method and high rearing density, Mycoplasma Gallisepticum infection have already been a major problem that affects the poultry industry through its increased morbidity. MG infection can be easily triggered under such environment as poor ventilation , a sudden air temperature change and excessive ammonia and dusts ,even after vaccinating the live vaccine such as Newcastle disease, Infectious bronchitis and Infectious Laryngotracheitis can also triggered this disease.

随着养鸡集约化程度的提高，饲养方式的改变以及饲养密度的提高，在通风不良、空气中氨和灰尘增加或气温骤变等环境中极易诱发本病；甚至接种鸡新城疫、传染性支气管炎和传染性喉气管炎等活疫苗后也都可能诱发本病。

The protocol for the detections of all the AIV isolates, the H5-subtype and the optimization of reactions were studied with a H5-subtype reference isolate BSG1. A 229bp-band of AIV specific and a 380bp-band of H5 subtype specific were amplified individually with the designed primers of AIV specific and H5-subtype specific respectively by the developed RT-PCR technique from isolate BSG1. A double-PCR was also developed which can detect all the AIVs and identify the H5-subtype AIVs. The results of specificity experiment showed that there was no specific band could be amplified with the samples of Newcastle disease virus, infectious bronchitis virus, infectious laryngotracheitis virus, egg drop syndrome virus and infectious bursal disease virus.

结果应用通用引物可从BSG1毒株扩增到与预计大小相符的229bp AIV特异性片段，应用H5亚型鉴定引物则可从BSG1毒株扩增到与预计大小相符的380bp H5亚型特异性片段；在此基础上建立了可检测所有AIV毒株以及可同时进行H5亚型毒株鉴定的二重RT-PCR方法；检测方法的特异性试验结果表明，该方法对新城疫病毒、传染性支气管炎病毒、传染性喉气管炎病毒、产蛋下降综合症、传染性法氏囊病毒无交叉反应；检测方法的敏感性试验结果表明，通用引物扩增、H5亚型特异性引物扩增以及二重PCR扩增反应的组织样品总RNA的最低检出量分别为0.0217μg、0.0217μg和2.17μg；对20份临床样品检测中，有10份为AIV阳性，其中有5份为H5亚型病毒阳性。

In order to fully know the alteration of microbial community in chick, the influence of different kinds of pathogenic microorganism on chick, and the difference of intestinal flora, in this paper analysed the structure of intestinal flora of pullorum disease group, newcastle disease group and healthy group by ERIC-PCR based fingerprint on Molecular Ecology.

中文摘要：为了全面掌握鸡肠道微生物群落结构变化，人工感染病原微生物对雏鸡肠道菌群结构的影响以及不同类型病原微生物对菌群的影响是否存在差异，本文应用ERIC-PCR指纹图谱技术，对鸡白痢、新城疫感染雏鸡以及健康鸡的肠道菌群结构特征进行了分子生态学研究。

In clean diluent condition, the median lethal concentration (MLC50) of CIO2 against bacteria and yeast was 9.4 and 8.4 ppm, respectively. In dirty diluent condition, the MLC50 of CIO2 against bacteria and yeasts was 39.9 and 24.3 ppm, respectively. The virucidal activity of CIO2 against 100 median embryo lethal dose (100 ELD50) of Newcastle disease virus, avian influenza virus, infectious bronchitis virus and infectious bursal disease virus was 1.2, 1.2, 2.5 and 1.2 ppm, respectively.

发现CIO2在乾净稀释液中对细菌和酵母菌的中间致死浓度(MLC50)分别为9.4和8.4ppm，CIO2在污浊稀释液中对细菌和酵母菌的MLC50分别为39.9和24.3ppm，CIO2之杀灭新城病病毒、H6N1型家禽流行性感冒病毒、传染性支气管炎病毒和传染性华氏囊炎病毒的浓度分别为1.2、1.2、2.5和1.2ppm。
