Perspectives

MICROBIOLOGY:
Chitin, Cholera, and Competence

Douglas H. Bartlett and Farooq Azam

Vibrio cholerae, a human pathogen, inhabits aquatic environments and is often associated with chitin-containing organisms. In their Perspective, Bartlett and Azam discuss the findings of Meibom et al. in the same issue of chitin-mediated natural DNA transformation in V. cholerae. This finding opens a new window for understanding conditions that influence the evolution of this bacterium in aquatic habitats.
