Sampling of the environment was undertaken in two distinct phases. During phase 1, 38 shower drains and 38 toilet bowls, defined as the wet environment, were sampled using swabs. Phase 2 consisted in sampling adjacent dry surfaces, using wipes in rooms that had tested positive during phase 1. Samples were plated on a selective medium (chromID®CARBASMART, bioMérieux).
