Major surface protein 2 of Anaplasma phagocytophilum facilitates adherence to granulocytes.

abstract：:Borrelia burgdorferi, the Lyme disease pathogen, dramatically alters its protein profile when it is transmitted between ticks and mammals. Several differentially expressed proteins have been shown to be critical for the enzootic cycle of B. burgdorferi. In this study, we demonstrated that expression of the surface lip...
