As shown in Fig. 5, individual serum samples from eleven immunocompetent, ID-injected mice reacted on a line immunoblot (LIA) with the following antigens, which are indicative of infection with borreliae belonging to the Bb complex: a strong signal with VlsE mix (10/10); strong/moderate signals with OspC mix (8/10), BmpA (7/10) and p58 (5/10); and weak signals with DbpA mix (10/10) and p83 (8/10). This evidence concerns the gene YBX3 and infection.
