I know that S. aureus and most gram-negative rods are facultative anaerobes. In terms of number of species, are most human pathogen-associated bacteria facultative anaerobes?

  • $\begingroup$ Most bacteria are facultative anaerobes. There are very few, if any, obligately aerobic bacteria. Wikipedia lists Mycobacterium tuberculosis as obligate aerobe but it can survive in anaerobic conditions. $\endgroup$ – WYSIWYG Sep 11 at 8:23
  • $\begingroup$ Thanks. Yes, there are only a few as you mentioned. Moraxella catarrhalis, Legionella pneumophila, and Pseudomonas aeurginosa are some examples. $\endgroup$ – Rome Sep 11 at 11:38
  • $\begingroup$ P.aeruginosa can survive in anaerobic conditions. $\endgroup$ – WYSIWYG Sep 11 at 19:33
  • $\begingroup$ In the presence of arginine or nitrate, yes. However, in general terms it is considered aerobic. $\endgroup$ – Rome Sep 11 at 21:09
