厭氧芽胞桿菌MH21,細(xì)胞呈直桿狀,0.5~2.5μm×1.2~10μm,常以成對(duì)或鏈狀排列,具圓端或方端。細(xì)胞染色大多數(shù)在幼齡培養(yǎng)時(shí)呈現(xiàn)革蘭氏陽(yáng)性,以周生鞭毛運(yùn)動(dòng)。芽孢橢圓、卵圓、柱狀、圓形,能抗許多不良環(huán)境。每個(gè)細(xì)胞產(chǎn)一個(gè)芽孢,生孢不被氧所抑制。好氧或兼性厭氧,具有對(duì)熱、pH和鹽各種多樣性的生理特性。化能異養(yǎng)菌,具發(fā)酵或呼吸代謝類型。通常接觸酶陽(yáng)性。發(fā)現(xiàn)于不同的生境,少數(shù)種對(duì)脊椎動(dòng)物和非脊椎動(dòng)物致病。厭氧芽胞桿菌MH21只有一個(gè)屬,稱梭狀芽胞桿菌屬(clostridium),簡(jiǎn)稱梭菌屬,革蘭氏染色陽(yáng)性,都能產(chǎn)生芽胞,芽胞直徑大多比菌體寬,使菌體膨大成梭形,故得名。芽胞的形狀和位置在鑒別上有意義。大多數(shù)須在嚴(yán)格厭氧條件下才能生長(zhǎng),少數(shù)可在微氧環(huán)境中繁殖。
