I thought Lyme’s could be one or more of like 6 or 9 different things the tick can carry?
The term "Lyme disease" specifically refers to an infectious disease caused by bacteria of the genus Borrelia, primarily Borrelia burgdorferi in the United States, transmitted through the bite of infected blacklegged ticks (e.g., Ixodes scapularis or Ixodes pacificus).
It’s not a label for multiple distinct diseases but rather a single condition with a range of manifestations and stages—early localized, early disseminated, and late disseminated—that can affect various systems (skin, joints, heart, nervous system).
BUT...Co-Infections: Blacklegged ticks can carry other pathogens besides Borrelia, leading to diseases that might occur alongside Lyme or be mistaken for it. Examples include:
| Anaplasmosis | Anaplasma phagocytophilum |
| Babesiosis | Babesia microti |
| Powassan virus disease | |
| Ehrlichiosis | Ehrlichia species |
| Borrelia miyamotoi disease | a relapsing fever-like illness, distinct from Lyme |
| Tularemia | Francisella tularensis, less common |
| Rocky Mountain spotted fever | Rickettsia rickettsii, rare via Ixodes ticks |

while various ticks are vectors for various bacterial [and viral and parasitic] infectious diseases, each tick-borne infection type and disease are distinct and each have a distinct name .. Lyme disease is one such disease and is caused only by infection with Borrelia burgdorferi ...
