  snippet: Campylobacter jejuni, the leading cause of human bacterial gastroenteritis,
    requires low environmental oxygen and high carbon dioxide for optimum growth
  notes: Al-Haideri et al. support elevated carbon dioxide as a growth condition required
    by capnophilic Campylobacter jejuni.

  snippet: Taken together, our data suggest CanB is a major contributor to the capnophilic
    growth phenotype of C. jejuni.
  notes: Al-Haideri et al. describe the elevated-CO2 requirement as a capnophilic
    growth phenotype and identify CanB as a major contributor in C. jejuni NCTC 11168.
