''Clostridium cadaveris'' is an enteric, gas-forming, motile, strictly anaerobic gram-positive bacterium of the genus ''Clostridium''. First described by Klein in 1899, it was noted to be the most prominent bacteria during human decomposition; historically it was described as "putrefying flora". ''Clostridium cadaveris'' is usually considered non-pathogenic; unlike other species of ''Clostridium'', it does not produce toxins.''Clostridium cadaveris'' is found in soil, water, and is a normal component of the human intestinal tract. The genus ''Clostridium'' is large and phylogenetically diverse comprising over 150 species. Clostrida are extensively found in nature predominately as benign soil saprophytes.A number of ''Clostridium'' species are pathogenic to humans. Members including ''C.botulinium'', ''C. perfringens'', and ''C.septicum'' are spore forming and the cause of botulism and gas gangrene respectively. ''Clostridium cadaveris'' is closely related phylogenetically to ''Clostridium fallax'' and ''Clostridium intestinale''. Infections in humans due to ''C. cadaveris'' are rare and the organism is seldom found is clinical specimens. Most cases reported in medical literature document infections in immunocompromised patients, but isolated cases in immunocompetent hosts have been reported. ==Colony characteristics== Primary isolation media is blood agar incubated anaerobically at 35-37 degrees Celsius for 40–48 hours. Microscopic appearance shows gram positive rods with both smooth and rough colony types and further spore staining technique may be utilized to determine spore shape and position. Currently the standard to identify clostrida species such as ''C. cadaveris'' is via molecular techniques utilizing ribosomal RNA gene sequencing. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Clostridium cadaveris」の詳細全文を読む スポンサード リンク
