Persistent West Nile virus associated with a neurological sequela in hamsters identified by motor unit number estimation.

abstract：:Retroviruses use RNA as their genetic material within viral particles and DNA (provirus) as their genetic material within cells. The rate of recombination during reverse transcription between two identical sequences within the same RNA molecule is very high. In this study, we have developed a sensitive system to study...
