In the Northeast and upper Midwest of the United States, Babesia microti and Borrelia burgdorferi use Ixodes scapularis ticks as vector and Peromyscus leucopus mice as major reservoir host. We previously established, in a 5-year field trial, that a reservoir-targeted outer surface protein A vaccine reduces the prevalence of B. burgdorferi-infected ticks. We accessed ticks and mouse blood samples collected during the trial, extracted total DNA, and amplified the B. microti 18S rRNA gene. Vaccine deployment reduced the prevalence of ticks coinfected with B. microti and that of mice infected with B. microti. Breaking the enzootic cycle of B. burgdorferi may reduce the incidence of babesiosis.

As per published literature, the tick is the primary Lyme disease vector in British Columbia (BC), while the tick species is the dominant vector on the East Coast of Canada, with no . presence seen in BC. However, a recent publication reported presence of in BC which initiated this study to determine the accuracy of the microscopic identification of ticks received in the BC Centre for Disease Control (BCCDC) Public Health Laboratory and compare morphologic methods to molecular methods.

Background: Lyme disease is the most common tick-borne illness in the United States, and cases of Lyme disease have nearly doubled since the early 2000s. Symptoms and presentation vary based on severity of illness, with more serious complications of disease consisting of neurologic and cardiac dysfunction. Testing is often unreliable, which can lead to delayed diagnosis and management.

A novel panel of peptide for serological identification of Borrelia burgdoferi sensu stricto, Borrelia garinii and Borrelia afzelii was developed and assessed in this study. The diagnostic algorithm of the novel test was initially trained testing 10 US human sera including 3 early-stage and 3 late-stage Lyme disease positive sera, 2 sera positive for Babesia and 2 sera positive for Syphilis, all purchased from a private biorepository. Findings were then corroborated testing (a) 33 additional EU follow-up positive sera from seroconverted patients bitten by ticks that tested positive for B.

Host-pathogen interactions represent a dynamic evolutionary process, wherein both hosts and pathogens continuously develop complex mechanisms to outmaneuver each other. Borrelia burgdorferi, the Lyme disease pathogen, has evolved an intricate antigenic variation mechanism to evade the host immune response, enabling its dissemination, persistence, and pathogenicity. Despite the discovery of this mechanism over two decades ago, the precise processes, genetic elements, and proteins involved in this system remain largely unknown.

Skin biopsies from tick bite sites are frequently collected and tested for the presence of spirochetes ( spp.), which remain elusive.
