    Evaluation of in-vitro antibiotic susceptibility of different morphological forms of Borrelia burgdorferi

    ByCanLyme Team December 4, 2012April 21, 2023

    Background: Lyme disease is a tick-borne illness caused by the spirochete Borrelia burgdorferi. Although antibiotic therapy is usually effective early in the disease, relapse may occur when administration of antibiotics is discontinued. Studies have suggested that resistance and recurrence of Lyme disease might be due to formation of different morphological forms of B. burgdorferi, namely…

    Updates on Borrelia burgdorferi sensu lato complex with respect to public health

    ByCanLyme Team December 3, 2012April 21, 2023

    Summary Borrelia burgdorferi sensu lato (s.l.) complex is a diverse group of worldwide distributed bacteria that includes 18 named spirochete species and a still not named group proposed as genomospecies 2 (Postic et al., 2007). Descriptions of new species and variants continue to be recognized, so the current number of described species is probably not…
