[Studies on new adenovirus types of subgenus D causing conjunctivitis--antigenic and restriction endonuclease analysis of adenovirus types 19 and 37].

Neutralization test and DNA restriction endonuclease analysis were performed in strains of adenovirus types 19 (Ad-19) and 37 (Ad-37) isolated from patients with acute conjunctivitis in Sapporo, Kao-Hsiung (Taiwan) and Pusan (Korea) in the period of 1979 and 1984. Although Ad-19 and Ad-37 were differentiated, they were related to each other in neutralization test. There was no difference between prototype strain and isolates in Ad-19 and Ad-37 strains. By DNA restriction endonuclease analysis Ad-19 isolates were clearly distinct from Ad-19 prototype strain (AV-587) and Ad-37 strains. And it was suggested that these Ad-19 isolates from East Asia were as same as isolates from Europe named Ad-19a. Ad-37 isolated strains were as same as Ad-37 prototype strain (GW) by SmaI, SacI, SalI, BamHI, EcoRI, XhoI, HindIII restriction analysis. But some strains were distinct from prototype strain by only HindIII restriction analysis, and they were new subtype of Ad-37 which had never been reported.
