Answer

The body louse can be the vector of R prowazeki, which causes typhus; B quintana, which causes trench fever; and B recurrentis, which causes relapsing fever. Evidence shows that some infectious organisms are altered by their arthropod vector and that disease manifestations may be vector-specific. For example, bartonellosis spread by a louse has different manifestations from bartonellosis spread by a flea or biting fly. [12]
