[Analysis of Borrelia burgdorferi genostrains among patients with Lyme disease]

Abstract

Background: Lyme borreliosis is a zoonose which can be transmitted to the humans during Ixodes tick bite to the skin. The disease is caused by bacteria--spirochetes of the Borrelia species, classified as Borrelia burgdorferi strain. In Poland Lyme borreliosis is caused by Borrelia garinii, Borrelia afzelii and Borrelia burgdorferi sensu stricto. The presence of Borrelia spielmani was recently reported.

Material and methods: The study included 249 patients diagnozed in University Hospital in Krakow due to suspicion of Lyme borreliosis in 2005-2008. Results of serologic tests against borreliosis were analized using Elisa tests (Mikrogen), positive tests were confirmed using Western blot tests (Biomedica).

Results: It was found the high percentage of the antibodies in class IgM, which are important in acute phase of borreliosis, typical for Borrelia garinii, whereas in class IgG it was found the prevalence of protein typical for Borrelia afzellii and Borrelia burgdorferi sensu stricto. It was found the high prevalence of the presence VIsE reacting with IgG antibodies. It was noted the presence of Borrelia spielmani genostrain in Poland.
