Comparative Analysis of Tick-Borne Relapsing Fever Spirochaetes from Ethiopia and Nigeria

Pathogens, 2023
Despite increasing reports of tick-borne diseases in Africa, remarkably, reports of tick-borne relapsing fever (TBRF) in Nigeria are lacking. Ornithodoros savignyi from Nigeria have been reported with the relapsing fever Candidatus Borrelia kalaharica ...

Typing African Relapsing Fever Spirochetes

Emerging Infectious Diseases, 2005
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.

Emerging bacterial infectious diseases/pathogens vectored by human lice

Travel Medicine and Infectious Disease, 2023
Human lice have always been a major public health concern due to their vector capacity for louse-borne infectious diseases, like trench fever, louse-borne relapsing fever, and epidemic fever, which are caused by Bartonella quintana, Borrelia recurrentis,

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.

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.

Human Pathogens in Body and Head Lice

Emerging Infectious Diseases, 2002
Using polymerase chain reaction and sequencing, we investigated the prevalence of Rickettsia prowazekii, Bartonella quintana, and Borrelia recurrentis in 841 body lice collected from various countries. We detected R.

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.

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 ...

Identification and Structural Characterisation of Novel Outer Membrane Proteins in the genus Borrelia [PDF]

Although considered Gram-negative the outer membrane (OM) of Borrelia is unique, consisting of a variety of glycolipids, a significant number of surface exposed lipoproteins and a smaller number of integral membrane-spanning β-barrels.
