More importantly, they carry diseases as the primary hosts of pathogens such as spirochaetes, and without their agency, the organisms could not reach their secondary hosts.

He traveled to Africa to try to confirm his findings; and he wanted to test the hypothesis that yellow fever was caused by spirochaete bacteria instead of a virus.
33.
With the support of his assistant Sahachiro Hata Ehrlich discovered in 1909 that Compound 606, Arsphenamine effectively combatted " spirillum " spirochaetes bacteria, one of whose subspecies causes syphilis.
34.
In 1913 all doubt about the syphilitic nature of paresis was finally eliminated when Hideyo Noguchi and J . W . Moore demonstrated the syphilitic spirochaetes in the brains of paretics.
35.
Given that the CSI is exclusively shared by members within this phylum, it has been postulated that it may be related to the characteristic flagellar properties observed among Spirochaetes species.
36.
Bacterial examples, in particular in the Caribbean and parts of South America, include the transmission of " Treponema pallidum pertenue ", the spirochaete that causes yaws.
37.
The symptoms of syphilis have become less severe over the 19th and 20th centuries, in part due to widespread availability of effective treatment and partly due to virulence of the spirochaete.
38.
The PilZ domain is also implicated in the bacterial pathogenicity of the Lyme disease spirochaete, " Borrelia burgdorferi ", through its binding partner c-di-GMP.
39.
One of the keys of the success of " I . scapularis " as a " Borrelia " vector relies on its ability to limit the proliferation of the spirochaete.
40.
Relapsing fever spirochaetes have a unique process of DNA rearrangement that allows them to periodically change the expression of the VMPs in their outer membrane, which results in the generation of multiple serotypes.
