摘要
应用无菌笼具复合体,使雏鸡处于微生物群受控和严格隔离状态,把鸡白痢病垂直传播和水平传播截然分开,以便研究其传播特征。结果表明,19%的阳性鸡群后裔,可以从其体内分离到鸡伤寒-白痢沙门氏菌,而阴性鸡群为5%。两周龄内保护雏鸡免遭外界环境中沙门氏菌的感染,在本病的生态防制上颇为重要。
The germfree cage-complex was used to separate completely the vertical and horizon-tal infections in order to study the spreading characteristic of chick white scours(CWS).The resultsindicated that Salmonella gallinarum-pullorum(S_(gp))could be isolated by 19% in the offsprings from pos-itive reaction breeders by means of rapid whole-blood test and by 5%in the offsprings from nega-tive reaction breeders by the same test.It was considerable significance that protecting chick to avoidbeing infected by S_(gp) from environment during the first two-weeks of life for ecocontrolling ofCWS.
