HAdV3 genome types as identified by restriction enzyme analysis with Bam HI. The gel patterns reveal that most of the HAdV3 genome types found were in the HAdV3a genome cluster save for HAdV3p1 (lane p1). Lane designations: M1 and M2 are Bio-Rad EZ Load 100 bp (3 kb range) and 1 kb molecular rulers, respectively (Hercules, CA). Lane 3p=prototype HAdV3p virus (strain GB, US, 1953); lane 3a2=reference HAdV3a2 virus (CDC, 2005). HAdV3 REA patterns from study specimens: p1=HAdV3p1; a=HAdV3a; a2=HAdV3a2; a17=HAdV3a17; a50=HAdV3a50; a51=HAdV3a51.
