P. Brouqui et al., EUKARYOTIC CELLS PROTECT BORRELIA-BURGDORFERI FROM THE ACTION OF PENICILLIN AND CEFTRIAXONE BUT NOT FROM THE ACTION OF DOXYCYCLINE AND ERYTHROMYCIN, Antimicrobial agents and chemotherapy, 40(6), 1996, pp. 1552-1554
Despite appropriate antibiotic treatment, Lyme disease patients may ha
ve relapses or may develop chronic manifestations. The intracellular l
ocation of Borrelia burgdorferi suggests that antibiotics that penetra
te cells will have greater efficiency. Doxycycline or erythromycin was
more effective than penicillin or ceftriaxone in killing B. burgdorfe
ri when the organism was groan in the presence of eucaryotic cells.
