Testing the Competence of Cimex lectularius Bed Bugs for the Transmission of Borrelia recurrentis, the Agent of Relapsing Fever. [PDF]

Am J Trop Med Hyg, 2019
In recent years, bed bugs have reappeared in greater numbers, more frequently, and are biting humans in many new geographic areas. Infestations by these hematophagous insects are rapidly increasing worldwide. Borrelia recurrentis, a spirochete bacterium, is the etiologic agent of louse-borne relapsing fever.

Background to new treatments for COVID‐19, including its chronicity, through altering elements of the cytokine storm

Reviews in Medical Virology, Volume 31, Issue 5, Page 1-13, September 2021., 2021
Summary Anti‐tumour necrosis factor (TNF) biologicals, Dexamethasone and rIL‐7 are of considerable interest in treating COVID‐19 patients who are in danger of, or have become, seriously ill. Yet reducing sepsis mortality by lowering circulating levels of TNF lost favour when positive endpoints in earlier simplistic models could not be reproduced in ...

Age‐Based Variations in the Gut Microbiome of the Shennongjia (Hubei) Golden Snub‐Nosed Monkey (Rhinopithecus roxellana hubeiensis)

BioMed Research International, Volume 2021, Issue 1, 2021., 2021
The gut microbiota represents a source of genetic and metabolic diversity of a complex polymicrobial ecosystem within its host. To investigate age‐based variations of the gut microbiota among Shennongjia golden snub‐nosed monkeys (Rhinopithecus roxellana hubeiensis), we characterized the microbial species in fecal samples from 18 Shennongjia golden ...

Whole-genome sequences of six <i>Borrelia recurrentis</i> strains obtained via PacBio sequencing. [PDF]

Microbiol Resour Announc
ABSTRACT Provided are whole-genome sequences of six Borrelia recurrentis strains that had been earlier isolated from louse-borne relapsing fever patients. The sequences of each genome presented here included one linear chromosome and 5 linear plasmids, whose average size was

Culture of Ethiopian Strains of Borrelia recurrentis [PDF]

Applied Microbiology, 1973
A number of standard bacteriological media with supplements were tested for their ability to support in vitro growth of Ethiopian strains of Borrelia recurrentis . Propagation of 18 out of 21 strains occurred in Trypticase soy yeast broth to which bovine albumin (fraction V),

Multispacer sequence typing relapsing fever Borreliae in Africa.

PLoS Neglected Tropical Diseases, 2012
BackgroundIn Africa, relapsing fevers are neglected arthropod-borne infections caused by closely related Borrelia species. They cause mild to deadly undifferentiated fever particularly severe in pregnant women.

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 ...

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,

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.

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.
