Quote- "One sample from a mite of genus Haemogamasus was successfully isolated, and the specimen was confirmed as B. afzelii by using PCR-RFLP and by gradient SDS-PAGE. This suggests the possible participation of gamasid mites in borrelial circulation in nature and also points to the utility of further such studies to identify potential vectors (other than ticks) of the spirochete."
