Numerical diagnoses of superinfection in chronic hepatitis B viral dynamics.

abstract：:We have analyzed viral DNA patterns, obtained following digestion of six different infectious bovine rhinotracheitis isolates, using a panel of restriction enzymes. Several differences in profiles were observed, particularly for a Canadian viral strain which presumably contained a genome that was larger than the other...
