摘要
[Objective] The aim of this study is to quantitatively analyze the Fusarium concentration and distribution in air and the surrounding substrates(feed,feces,dust,soil)in the chicken house to provide a scientific basis for the control and early warning of Fusarium infection in poultry and practitioners.[Method]Air samples collected by a 6-stage Anderson air microorganism sampler and exposed culture plates as well as substrate samples gathered by aseptic bags were cultured,counted and purified in the lab.[Result]717 strains of Fusarium isolates were obtained and the dust had the highest Fusarium concentration among the samples(2.8×105-1.5×106 CFU/g with an average of 8.8×105 CFU/g).[Conclusion]The Fusarium distribution in the air was in high correlation with those in soil and dust.
