Abstract

Recoveries of Clostridium difficile from stool specimens by using three media, cycloserine-mannitol agar (M-CMA), cycloserine-mannitol-blood agar (M-CMBA), and cycloserine-cefoxitin agar (M-CCA), were compared. Of 321 clinical specimens, 37 yielded C. difficile. Thirty-four were positive on M-CCA, 21 were positive on M-CMA, and 20 were positive on M-CMBA. M-CCA recovered significantly more C. difficile than did M-CMBA or M-CMA.

摘要

比较了使用三种培养基(环丝氨酸甘露醇琼脂(M-CMA)、环丝氨酸甘露醇血琼脂(M-CMBA)和环丝氨酸头孢西丁琼脂(M-CCA))从粪便标本中分离艰难梭菌的情况。在321份临床标本中,37份培养出艰难梭菌。34份在M-CCA上呈阳性,21份在M-CMA上呈阳性,20份在M-CMBA上呈阳性。M-CCA分离出的艰难梭菌显著多于M-CMBA或M-CMA。
