Unfortunately, the more co-infections that are present, the more severe the illness and the longer the recovery period. Treatments for infections are also often different than those used for Borrelia. For example, doxycycline, an effective treatment for Borrelia, is also effective for Ehrlichia but not Babesia, a malarial-like parasitic organism. Similarly, Bartonella and Mycoplasma must be treated with different antibiotics. Bartonella may be the most common of all tick-borne pathogens. In addition to ticks, Bartonella can be transmitted by fleas, lice, sand flies, cat scratches and possibly other insects. The strain of Bartonella that is transmitted by ticks seems to be different than the strain that results in cat scratch disease. One indication of this is the fact that usual Bartonella medications do not work for the tick-borne strain.
