- B. burgdorferi infects the skin after a tick attaches for at least 24 hours. From the skin, the spirochete spreads hematogenously or lymphatically to other organs. The human host mounts an adaptive and innate immune response resulting in macrophage, and antibody-mediated control and eradication of B. burgdorferi.

Jan 20, 2023 · Borrelia mayonii is rarely found in ticks and has only been detected in blacklegged ticks in the north-central United States. Blacklegged ticks have a 2-to-3-year life cycle. During this time, they go through four life stages: egg, larva, nymph, and adult.

B. burgdorferi life cycle. B. burgdorferi infects a wide range of vertebrate animals including small mammals, lizards, and birds [33–39]. Ticks of the genus Ixodes transmit B. burgdorferi between hosts and are the only natural agents through which humans have been shown to become infected [2, 40].

Abstract. The Lyme disease spirochete, Borrelia burgdorferi, exists in a zoonotic cycle involving an arthropod tick and mammalian host. Dissemination of the organism within and between these hosts depends upon the spirochete's ability to traverse through complex tissues.
Life cycle. B. burgdorferi circulates between Ixodes ticks and a vertebrate host in an enzootic cycle. B. burgdorferi living in a tick is mainly acquired through blood meals from an infected, competent vertebrate host, but rare cases of transovarial transmission exist.
