Abstract

The multitest V. cholerae medium (VC medium) for rapid presumptive identification of Vibrio cholerae was evaluated. On the basis of reactions in the VC medium, 379 strains recovered during a yearlong ecological study in Calcutta were presumptively identified as V. cholerae. Further phenotypic characterization of these strains revealed that the reactions of 371 (97.9%) isolates were consistent with that of V. cholerae. False-positive reactions were exhibited by eight (2.1%) strains, three of which were identified as Vibrio fluvialis biotype 1. By slightly varying the basic formulation of the VC medium, we could eliminate some false-positive reactions. On the basis of the present evaluation, we recommend the routine use of the VC medium.

摘要

对用于快速初步鉴定霍乱弧菌的多测试霍乱弧菌培养基(VC 培养基)进行了评估。根据在 VC 培养基中的反应,在加尔各答为期一年的生态学研究中回收的 379 株菌株被初步鉴定为霍乱弧菌。对这些菌株的进一步表型特征分析表明,371 株(97.9%)分离株的反应与霍乱弧菌一致。8 株(2.1%)菌株出现假阳性反应,其中 3 株被鉴定为河流弧菌生物型 1。通过略微改变 VC 培养基的基本配方,我们可以消除一些假阳性反应。基于目前的评估,我们建议常规使用 VC 培养基。
