Comparison of two media for the isolation of thermophilic Campylobacters from waste waters of different quality.

Counts of thermophilic campylobacters from 31 different waste water samples were parallel estimated with two different cultivation media. The resulting increased isolation sale obtained with an modified Charcoal-Cefoperazone-Deoxycholat-Medium (MCCD-Medium), was statistically significant. An 15.8 fold increased isolation rate, compared with the standard medium, could be estimated with the help of the geometric mean.
