The occurrence of Nm A was the main prevalence strain.

To study the genetic diversity and genotype of the native prevailing strains,a 28S rDNA group I intron marker-based genetic analysis was performed on 40 fungal strains representing the native population of Beauveria bassiana in Huangshan Mountain region.

Objective To study the epidemic isolates and antibiotic resistance of Vibrio cholera in Maoming Area,and provide the references for prevention and control of cholera.

The paper had three statistics about separating pathogenic bacteria in germ room between September 2007 and September 2008 as follows:the statistics of primary epidemic bacteria of the various samples based on sample source,the statistics of drug sensitive-ness of various common bacteria based on bacteria,viewing the variation of the antibacterial spectrum of the various antibacterials.
