“…Three of these patterns were composed of a single band of 884, 1,265, 650 bp and were designated RAPD patterns A, B, and C, respectively. One was composed of a clear band of 420 bp and three weak bands of 1,265, 918, and 444 bp, and it was designated RAPD pattern D. The RAPD pattern A was produced with DNAs extracted from the type strain of E. rhusiopathiae and from the reference strains of serovars 1a, 1b, 2, 4, 5,6,8,9,11,12,15,16,17,19, and 21 and type N, believed to be E. rhusiopathiae. The RAPD pattern B was produced with DNAs extracted from the type strain of E. tonsillarum and from the reference strains of serovars 3, 7, 10, 14, 20, 22, and 23, considered to be E. tonsillarum.…”
