Treatment. Patients diagnosed with infection due to B. mayonii have been successfully treated with a 2-4 week course of doxycycline. Amoxicillin, ceftriaxone, and cefuroxime have also been used.
Is Borrelia burgdorferi anaerobic?
Bb is an anaerobic bacteria, which can survive in areas where there are low levels of oxygen.
Does Borrelia burgdorferi require oxygen?
burgdorferi. Preliminary studies have shown that B. burgdorferi consumes O2 and grows in a microaerophilic atmosphere of 4% O2 but not in strictly aerobic or anaerobic environments. The spirochete produces a soluble hemolysin that is activated by a reducing agent such as cysteine.
Does Borrelia burgdorferi have endospores?
Some bacteria (Bacillus and Clostridia species) form protective heat-resistant structures called spores; however, Borrelia burgdorferi does not make spores.
