The epidemiology and geographic distribution of relapsing fever borreliosis in West and North Africa, with a review of the Ornithodoros erraticus complex (Acari: Ixodida). [PDF]

PLoS ONE, 2013
BACKGROUND: Relapsing fever is the most frequent bacterial disease in Africa. Four main vector / pathogen complexes are classically recognized, with the louse Pediculus humanus acting as vector for B. recurrentis and the soft ticks Ornithodoros sonrai, O.

Knowledge, Attitude, and Practice of Pediculus Capitis Prevention and Control and Their Predictors among Schoolchildren in Woreta Town, Northwest Ethiopia, 2018: A School‐Based Cross‐Sectional Study

International Journal of Pediatrics, Volume 2020, Issue 1, 2020., 2020
Background. Pediculus capitis is a human head lice infestation, a major public health issue that is most prevalent in resource‐limited countries globally. The current study aimed to assess the knowledge, attitude, and practice of pediculus capitis prevention and control and their predictors among schoolchildren in North West Ethiopia. Methods.

Phylogenetic origins of Borrelia recurrentis

International Journal of Medical Microbiology, 2008
Abstract Intragenic spacer (IGS, between 16S–23S genes) provides resolution among Lyme-borreliosis-associated spirochaetes and some relapsing fever Borrelia. When applied to East African relapsing fever borreliae, two and four types were found, respectively, among B. recurrentis and B. duttonii.

Multiplex real-time PCR diagnostic of relapsing fevers in Africa.

PLoS Neglected Tropical Diseases, 2013
BackgroundIn Africa, relapsing fever borreliae are neglected arthropod-borne pathogens causing mild to deadly septicemia and miscarriage. The closely related Borrelia crocidurae, Borrelia duttonii, Borrelia recurrentis and Borrelia hispanica are rarely ...

Population Structure of East African Relapsing Fever Borrelia spp.

Emerging Infectious Diseases, 2010
Differentiation of endemic East African tick-borne relapsing fever Borrelia duttonii spirochetes from epidemic louse-borne relapsing fever (LBRF) B. recurrentis spirochetes into different species has been questioned.

Characterisation of silent and active genes for a variable large protein of Borrelia recurrentis [PDF]

BMC Infectious Diseases, 2002
We report the characterisation of the variable large protein (vlp) gene expressed by clinical isolate A1 of Borrelia recurrentis; the agent of the life-threatening disease louse-borne relapsing fever.The major vlp protein of this isolate was characterised and a DNA probe created.

Novel approaches for the serodiagnosis of louse-borne relapsing fever

Frontiers in Cellular and Infection Microbiology, 2022
Louse-borne relapsing fever (LBRF) caused by B. recurrentis is a poverty-related and neglected infectious disease with an endemic focus in the Horn of Africa.

Phagocytosis of Borrelia recurrentis by blood polymorphonuclear leukocytes is enhanced by antibiotic treatment [PDF]

Infection and Immunity, 1980
The removal of Borrelia spirochetes from the blood in relapsing fever was studied by examining patients' blood phagocytic cells with the Dieterle silver stain. Polymorphonuclear leukocytes ingested Borrelia at increased rates for several hours after antibiotic treatment, during which time the total numbers of circulating plasma spirochetes were ...

Laboratory diagnosis of tick-borne African relapsing fevers: latest developments

Frontiers in Public Health, 2015
In Africa, relapsing fevers caused by ectoparasite-borne Borrelia species are transmitted by ticks, with the exception of Borrelia recurrentis, which is a louse-borne spirochete.
