In a nutshell: Spirochaetes are a type of bacteria. The biological category of Spirochaetes includes Borrelia, the microbes which cause Lyme Disease and Relapsing Fever, Treponema, which cause oral infections and Syphilis (syphilis can result in dementia in its final stages if untreated), and Leptospirosis, a serious disease spread by rodent urine. The spirochaetes which have been linked with Alzheimer’s Disease by researchers are Borrelia and oral spirochaetes.
