In 1982,Borrelia burgdorferi sensu stricto(ss) was identified as the aetiological agent of Lyme disease. Since then an increasing number ofBorrelia burgdorferi sensu lato(sl) species have been isolated in the United States. To date, many of these species remain understudied despite mounting evidence associating them with human illness.Borrelia bissettiiis a spirochaete closely related toB. burgdorferithat has been loosely associated with human illness. Using an experimental murine infection model, we compared the infectivity and humoral immune response with a North American isolate ofB. bissettiiandB. burgdorferiusing culture, molecular and serological methods. The originalB. bissettiicultures were unable to infect immunocompetent mice, but were confirmed to be infectious after adaptation in immunodeficient animals.B. bissettiiinfection resulted in spirochaete burdens similar toB. burgdorferiin skin, heart and bladder whereas significantly lower burdens were observed in the joint tissues.B. bissettiiinduced an antibody response similar toB. burgdorferias measured by both immunoblotting and the C6 ELISA. Additionally, this isolate ofB. bissettiiwas sequenced on the Ion Torrent PGM, which successfully identified many genes orthologous to mammalian virulence factors described inB. burgdorferi. Similarities seen between both infections in this well-characterized murine model contribute to our understanding of the potential pathogenic nature ofB. bissettii. Infection dynamics ofB. bissettii,and especially the induced humoral response, are similar toB. burgdorferi, suggesting this species may contribute to the epidemiology of human borreliosis.
