One thing I forgot to mention is that its more difficult to engineer
a negative strand virus than a positive strand one. If its +ve, you
can make a cDNA clone & transfect it in cells & recover progeny virus.
Works for alphaviruses (eg. Sindbis) picornaviruses (e.g. polio),
retroviruses (e.g. HIV). Recovering -ve strand virus from transfected
DNA has not been done reproducibly, as far as I know. Is there a
confirmed example I'm missing?

Cheers, Jon
