(Continued from p. 364) 3 discussions pullorum Salmonella pullorum from chickens caused by acute infectious disease characterized by acute diarrhea, loose stools white paste, was sepsis, in particular, the mortality rate of chickens infected with up to 4O ~ 8O, to the poultry industry by causing a significant loss of pay, how to prevent pullorum poultry industry has become the focus of attention. Zhengchangsheng Bacillus licheniformis 20386 as a new eco-agents have been used in clinical treatment of a variety of causes diarrhea and intestinal flora imbalance, its mechanism is the growth of bacteria into the intestinal tract can produce a variety of metabolic processes in the anti-vaccine active substance, for Staphylococcus aureus, Candida albicans strains with strong antagonistic effect on E. coli a role in promoting growth, while a large number of bacteria into the intestine, the consumption of free oxygen within the intestinal tract, resulting in environmental hypoxia, the physiological intestinal create the conditions for growth of anaerobic bacteria, anaerobic bacteria to adjust the intestinal group of the environment in which to restore the normal function of the intestinal tract. We process applications in the development of chicken pullorum Zhengchangsheng experimental model to prevent observation of a strong, results suggest that: the service Zhengchangsheng prevention case, copy the door first with pullorum attacks, the prevention group was significantly higher survival rate, but also higher than the natural diet group, indicating that the experimental infection of chickens Zhengchangsheng pullorum have a preventive role. with a copy pullorum bacteria attack the door, the chicken pullorum appears typical symptoms of stasis taking Zhengchangsheng given different doses of treatment, the mortality rate 075 million and 050 million two groups was significantly lower than the control group, the effect is better than chloramphenicol tangled, showing Zhengchangsheng have therapeutic effect of chicken pullorum. Preparation of the experimental group through the fecal flora survey chickens, dead chickens and pathogenic bacteria isolated dissection confirmed the above results. Zhengchangsheng with non-toxic, inexpensive, easy to preserve, and convenient, easy to promote and so on. ● Covent ■: [ ,],[of [M]. in the head in the Journal of the microbial .1990.2 (2). 1-13
