Abstract: Monoclonal antibodies and antibody fragments that selectively bind to invariant region 4 or 6 (IR4, IR6) of a VlsE (variable major protein-like sequence, expressed) protein. The VlsE protein is found on the surface of multiple variants of spirochete bacteria that cause Lyme disease. The protein is abundantly and continuously expressed throughout the bacteria's time in its vertebrate host and thus detection over the entire infection is enabled. A label may be attached to enable imaging of the bacteria.

Abstract: A method for switching traffic during real time stream transmission depends on a network side device to identify the start and end of the stream transmission, and to perform a switching between Best Effect traffic and the streaming traffic. The network side device can be a stream media content server, a Serving General Packet Radio Service (GPRS) Support Node (SGSN) or a Gateway General Packet Radio Service Supporting Node (GGSN) of a Core Network (CN). A system for switching traffic during a real time stream transmission, a content server for real time stream transmission, a GGSN for real time stream transmission, an SGSN for real time stream transmission are also disclosed.
