Abstract
Tick-borne lymphadenopathy (TIBOLA), also called Dermacentor-borne necrosis erythema and lymphadenopathy (DEBONEL), is defined as the association of a tick bite, an inoculation eschar on the scalp, and cervical adenopathies. We identified the etiologic agent for 65% of 86 patients with TIBOLA/DEBONEL as either Rickettsia slovaca (49/86, 57%) or R. raoultii (7/86, 8%).

Tick-borne lymphadenopathy (TIBOLA), called Dermacentor-borne necrosis erythema and lymphadenopathy (DEBONEL), is defined as the association of a tick bite, an inoculation eschar on the scalp, and cervical adenopathies
In 2002, R. raoultii DNA was detected in a D. marginatus tick taken from the scalp of a patient in whom TIBOLA/DEBONEL developed in France [4]
We describe several cases caused by the emerging pathogen R. raoultii [4], including patients with indirect molecular evidence of infection because the pathogen was detected in the ticks that had bitten them
Summary
Tick-borne lymphadenopathy (TIBOLA), called Dermacentor-borne necrosis erythema and lymphadenopathy (DEBONEL), is defined as the association of a tick bite, an inoculation eschar on the scalp, and cervical adenopathies. We identified the etiologic agent for 65% of 86 patients with TIBOLA/DEBONEL as either Rickettsia slovaca (49/86, 57%) or R. raoultii (7/86, 8%). In 1997, R. slovaca was described as a human pathogen and an agent of tick-borne lymphadenopathy (TIBOLA) [2] This syndrome, called Dermacentor-borne necrosis erythema and lymphadenopathy (DEBONEL), is defined as the association of a tick bite, an inoculation eschar on the scalp, and cervical lymphadenopathies [3]. The goal of this study was to identify the rickettsial agents in patients with TIBOLA/DEBONEL symptoms and in those who had an isolated tick bite on the scalp
