Adherence of Lyme disease spirochetes to rat lymphocytes.
In the present work, the capacity of Lyme disease (LD) Spirochetes to spontaneously adhere to rat lymphocytes has been evaluated. Borrelia organisms adhere to thymus, spleen, Payer's patches and peripheral blood lymphocytes in a higher frequency than that observed with Salmonella minnesota R345 (Rb) used as reference strain. Employing enriched splenic T and B cell populations, Spirochete binding to B lymphocytes is more elevated than that obtained with Salmonella, while similar percentage of T cells forms rosettes with both microorganisms. Taken together, these findings provide evidence for a novel mode of interaction between LD Spirochetes and host immune system.
