Other spirochetes

NetworkSection III Other helixes 1, regression helixes regression to the thermal helix (Borrelia recurrentis) causes regression heat, which is transmitted by arthropods as a medium. Regressive fever is an acute infectious disease characterized by periodic recurrents. The helix is a dredging helix genus, which causes two kinds of human diseases. First, for the return of the thermal helix, lice as the medium of transmission, causing the epidemic of regression fever, the domestic epidemic is mainly the return of this kind of heat. Second, the Dutton helix, with radon as the medium of transmission, causing local regression fever, rare in China.II, Endeavour's helixEndeavour's helix (Borrelia Vincenti) belongs to the dredging helix, living in the human mouth, generally does not cause disease, when the body's resistance is reduced, often with Thyrobacter pyrethrosis in the mouth in collaboration with Endeavour pharyngitis, gingivitis and so on.Lyme disease helixLyme disease spirochete is a type of hydrolytic helix that causes skin lesions mainly caused by erythema papules. It is a natural epidemic-borne disease that is mediated by radon and hosted by wild animals. The helix is a new species isolated from the 1970s and belongs to the longest (20 to 30um) and thinnest (0.2 to 0.3um) of the dredging helix.Hu Jun
