The spirochetal disease relapsing fever is caused by different Borrelia species. Relapsing fever is well recognized as an infection of the blood, but little is known about its predilection for the nervous system and the eyes. To investigate neurological and ocular involvement during relapsing fever, we reviewed the clinical manifestations, pathology, and treatment of relapsing fever of humans a...

BACKGROUND Tick-borne relapsing fever spirochetes are maintained in endemic foci that involve a diversity of small mammals and argasid ticks in the genus Ornithodoros. Most epidemiological studies of tick-borne relapsing fever in West Africa caused by Borrelia crocidurae have been conducted in Senegal. The risk for humans to acquire relapsing fever in Mali is uncertain, as only a few human case...

Relapsing fever Borrelia infections have attracted little attention in recent years; however, where endemic, these infections still result in considerable illness and death. Despite the marked antimicrobial drug susceptibility of these organisms, therapy is often delayed through lack of clinical suspicion. With increasing travel, infections may be imported, through exotic relapsing fever infect...

Relapsing fever Borrelia spp. challenge microbiologic typing because they possess segmented genomes that maintain essential genes on large linear plasmids. Antigenic variation further complicates typing. Intergenic spacer (IGS, between 16S-23S genes) heterogeneity provides resolution among Lyme disease-associated and some relapsing fever spirochetes. We used an IGS fragment for typing East Afri...

We are living with a lot of diseases related to fevers different names like Chikungunya fever, West Nile rheumatic Relapsing Rat-bite fever (sodoku), Haver hill Dengue Typhoid Scarlet Viral hemorrhagic etc.

tick-borne relapsing fever is an endemic disease in some parts of iran. borellia persica , the most common cause of this disease in iran, has a wide geographic distribution and is present in alborz and zagros mountain chains. here we report a 16–year-old male patient who presented with two episodes of fever within 15 days. he had a history of few overnight stays in a cave of mountainous area in...
