International audience. The cultural diagnosis of the causal agent of contagious equine metritis (Taylorella equigenitalis) using transport swabs is challenging. Swabs must be placed in Amies charcoal medium, refrigerated during transport, and plated out at the laboratory no later than 48 h after sampling. In this study, the viability of T. equigenitalis strain CIP 79.7T in 11 commercial swab transport systems was initially compared at 1 day and 2 days of storage at ambient (20 ± 3 °C) or refrigerated (5 ± 3 °C) temperature. The four best swab transport systems, systems B, E, F (used as the reference) and K, were then compared at 0, 2, 3, 4, 7 and 10 days at refrigerated temperatures. Statistically significant differences were observed after 10 days only for system K compared to the reference, with approximately 95% viable T. equigenitalis recovered in system K compared to approximately 77% in system F. System K is thus promising for preservation and transport of viable T. equigenitalis for culture.
