Biochemical reaction test
According to previously published methods (Devriese et al., 2005; Sasaki et al., 2007), the isolated pathogenic bacterial was inoculated into many micro-biochemical reaction tubes with the culture medium of sucrose, urea, arginine dihydrolase, xylose, lactose, mannose, wood alcohol, maltose, trehalose, mannitol, N-acetyl glucosamine, nitrate, VP-MR, fructose, melibiose, sorbitol, respectively, and then cultured at 37 ℃ for 24-36h. The results of these reactions were recorded and comparatively analyzed with the clinical microbiological diagnosis map for determining the genus of bacteria.
