Borrelia recurrentis

Borrelia recurrentis causes a relapsing fever in humans. Borrelia vincenti is the cause of Vincent s angina in humans, an ulcerative condition of the mouth and gums. Borrelia burgdorferi is the causal organism of the tick-borne Lyme disease.

Other Infections Actinomycosis, although most responsive to peniciUin G, may be successfully treated with a tetracychne. Minocychne is an alternative for the treatment of nocardiosis, but a sulfonamide should be used concurrently. Tetracychnes are useful in the acute treatment and for prophylaxis of leptospirosis. Borrelia spp., including B. recurrentis (relapsing fever) and B. burgdorferi (Lyme disease), respond to tetracychnes. The tetracychnes have been used to treat susceptible atypical mycobacteria. 

Relapsing fever Disease caused by various species of Borrelia, most commonly by B recurrentis-, transmitted by lice.
