Isolation and culture taking 3.2 diseased blood glucose agar was inoculated, and with the anaerobic culture method for bacterial isolation and culture, 37 ~ C cultured 24h, blood agar plates in the formation of small round, central uplift, white, opaque colonies around the hemolytic colonies. Pick a single colony staining,ghd deutschland, and saw a shape above the Gram-positive bacteria. 3.3 pathogenicity test animals with severe inflammation of the intestine to the contents, add 1 to 3 times diluted with normal saline, centrifuge 3000r/min Received: September 7, 2007 centrifuge 5min, the supernatant, and then by season's filter filtration, the filtrate obtained venous inoculation in mice 5, 0.2mL / only,UGG ブーツ, and the other with 5 as the control mice, intravenous injection of saline.
