Abstract

During the study of bacteria associated with bats affected by white-nose syndrome hibernating in caves in the Czech Republic, we isolated two facultatively anaerobic, Gram-stain-negative bacteria, designated strains 12(T) and 52(T). Strains 12(T) and 52(T) were motile, rod-like bacteria (0.5-0.6 µm in diameter; 1-1.3 µm long), with optimal growth at 20-35 °C and pH 6-8. On the basis of the almost complete sequence of their 16S rRNA genes they should be classified within the genus Serratia; the closest relatives to strains 12(T) and 52(T) were Serratia quinivorans DSM 4597(T) (99.5 % similarity in 16S rRNA gene sequences) and Serratia ficaria DSM 4569(T) (99.5% similarity in 16S rRNA gene sequences), respectively. DNA-DNA relatedness between strain 12(T) and S. quinivorans DSM 4597(T) was only 37.1% and between strain 52(T) and S. ficaria DSM 4569(T) was only 56.2%. Both values are far below the 70% threshold value for species delineation. In view of these data, we propose the inclusion of the two isolates in the genus Serratia as representatives of Serratia myotis sp. nov. (type strain 12(T) =CECT 8594(T) =DSM 28726(T)) and Serratia vespertilionis sp. nov. (type strain 52(T) =CECT 8595(T) =DSM 28727(T)).
