A modification of an existing selective medium for Clostridium difficile is described. Inclusion in the medium of DL nor-leucine and p-hydroxyphenylacetic acid enables identification of C difficile to be made directly from primary isolation plates by gas chromatographic detection of caproic acid and p-cresol. Plugs of agar withdrawn from the selective medium also allow the detection of cytotoxin production in vitro.
本文描述了一种对现有艰难梭菌选择性培养基的改良方法。在培养基中加入DL-正亮氨酸和对羟基苯乙酸,通过气相色谱法检测己酸和对甲酚,能够直接从初次分离平板上鉴定出艰难梭菌。从选择性培养基中取出的琼脂块也可用于体外检测细胞毒素的产生。
