Borrelia recurrentis is a species of Borrelia, a spirochaete bacterium associated with relapsing fever. [1] [2] B. recurrentis is usually transmitted from person to person by the human body louse. [3] Since the 1800s, the body louse has been known as its only known vector. [4]
Relapsing fever is a vector-borne disease caused by infection with certain bacteria in the genus Borrelia, [1] which is transmitted through the bites of lice, soft-bodied ticks (genus Ornithodoros), or hard-bodied ticks (Genus Ixodes).
It is one of the relapsing fever spirochaetes, which are globally distributed yet understudied agents of tick-borne relapsing fever. [2] The tick vector Ornithodoros turicata transmits B. turicatae, which causes relapsing fever, an arthropod-borne infection of humans and other mammals caused by different Borrelia species.
Relapsing fever (RF) borreliosis often occurs with severe bacteremia. [24] Twenty-five species of Borrelia are known to cause relapsing fever. [25] While most species use the soft tick family Argasidae as their vector, some outliers live in hard ticks or lice. [25] Relapsing fever can be spread epidemically through lice or endemically through ...
Borrelia miyamotoi is a bacterium of the spirochete phylum in the genus Borrelia.A zoonotic organism, B. miyamotoi can infect humans through the bite of several species of hard-shell Ixodes ticks, the same kind of ticks that spread B. burgdorferi, the causative bacterium of Lyme disease.
Treatment: Antibiotics – amoxicillin in pregnant adults and children, doxycycline in other adults [30] Relapsing fever (tick-borne relapsing fever, different from Lyme disease due to different Borrelia species and ticks) Organisms: Borrelia species such as B. hermsii, B. parkeri, B. duttoni, B. miyamotoi; Vector: Ornithodoros species
It is the endemic causative agent of tick-borne relapsing fever in parts of sub-Saharan Africa, and Madagascar. It is transmitted by the soft-bodied tick Ornithodoros moubata which sheds the pathogen in its saliva and coxal fluid. Vertical transmission occurs in ticks which thus appear to represent the major reservoir of this pathogen.
Tick-borne relapsing fever is transmitted through the bites of lice or soft-bodied ticks (genus Ornithodoros). [10] Each species of Borrelia is typically associated with a single tick species, with Borrelia duttoni being transmitted by O. moubata , and being responsible for the relapsing fever found in central, eastern, and southern Africa.
