OBJECTIVE To study the incidence of tick borne relapsing fever (TBRF) during the last 50 years, once like malaria an endemic disease in Sengerema, Tanzania. DESIGN By analyzing the annual reports, focusing on the number of admissions, maternal deaths, blood smears of patients with fever for Borrelia. SETTING Sengerema district, Tanzania. SUBJECT Admissions in Sengerema Hospital due to TBR...

background: a molecular survey was conducted to investigatethe presence of pathogenic borrelia persica species caus­ing the tick borne relapsing fever (tbrf) in takistan district qazvin province, western iran. methods: a number of 1021 s oft ticks were collected from 31 villages including previously reported infected and none-infected tbrf cases and individually examined for the presenceof b. p...

Relapsing fever is caused by the Borrelia species of spirochetes. Louse-borne epidemics of the disease may happen but the endemic disease is generally transmitted to humans by the bite of an infected tick (Ornithodorus). Clinical and laboratory findings of tick-borne relapsing fever in children in the north-west of Iran, Qazvin, were evaluated. This study was conducted from September 1992 to Se...

BACKGROUND The ongoing drought in sub-Saharan countries has led to the colonisation of west African Savanna by Ornithodoros sonrai; this tick acts as a vector for Borrelia crocidurae, which causes tick-borne relapsing fever (TBRF). Our aim was to ascertain the incidence of TBRF in west Africa. METHODS From 1990 to 2003, we monitored the incidence of TBRF in Dielmo, Senegal, by daily clinical ...

Tick-borne Relapsing Fever (TBRF) is a vector-borne disease of humans which causes serious illness, primarily for children under five years old and pregnant women. Understanding people's knowledge, attitude and practices on the disease is important in designing appropriate interventions. This study was conducted to explore community knowledge, attitudes and practices regarding TBRF transmission...

Tick-borne relapsing fever (TBRF), is caused by several species of Borrelia spirochetes, which are transmitted to humans through the bites of Ornithodoros spp. soft ticks. Wild rodents and insectivores are common reservoir hosts. TBRF is responsible for recurring fever associated with spirochetemia. The epidemiology of TBRF has not been well documented in South America where three endemic ticks...

Background: Tick-Borne Relapsing Fever (TBRF) was once a major world-wide epidemic disease and was an endemic disease like malaria in Sengerema district, close to Lake Victoria, Tanzania. Our aim was to study the incidence and fatality of TBRF over the past 60 years. Methods: From 1962 to 2015, we analyzed the annual reports, number of admissions, blood smears of patients with fever from Borrel...

Records from 182 cases of tick-borne relapsing fever (TBRF) were reviewed. In confirmed cases, there was febrile illness, and spirochetes were identified on peripheral blood preparations. In probable cases, there were clinical features of TBRF and either the same exposure as a confirmed case or serological (indirect fluorescent antibody test and western blotting [WB]) evidence of infection with...

Background and aims: Tick-Borne Relapsing Fever (TBRF) is a zoonotic disease involving many species of rodents and small mammals in widely distributed areas throughout the world. We describe the epidemiological and demographic characters of found cases of TBRF in the Bijar County, and briefly review it for preventing this illness in the year of 2007–2008. Methods: A confirmed patient was define...

West African tick-borne relapsing fever (TBRF) is difficult to diagnose due to the low number of spirochetes in the bloodstream of patients. Previously, the causative microorganism, Borrelia crocidurae, had never been cultured in vitro. TBRF was rapidly diagnosed for two patients returning from western Africa with fever of unknown origin by quantitative buffy coat (QBC) analysis. Diagnosis was ...
