查询词典 disease-producing

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.
