They are nonmotile, nonencapsulated, and nonsporing; they grow aerobically or microaerophilically but do not grow anaerobically. Brucella abortus, Brucella suis, Brucella melitensis, Brucella ovis, Brucella canis, and Brucella neotomae are the species of Brucella and their natural reservoirs.

Is Brucella aerobic or anaerobic?

Brucella spp. are small, nonmotile, nonsporing, noncapsulate GNCB. They are aerobic, but some strains require 5–10% carbon dioxide for primary isolation. Growth in vitro is slow and primary isolation may require 4 weeks incubation.

Is brucellosis anaerobic?

This bacteria is heterotrophic and can either carry out aerobic or anaerobic respiration because it is a facultative bacterium. In order to grow Brucella abortus, a very complex media is required, because it is a fastidious bacteria that requires most essential nutrients to be imported into the cell from the host.
