[Supplement No. XXVII (1983) to the Kauffmann-White scheme].

In this supplement are given the characters of 52 new Salmonella serovars recognized in 1983 by the WHO collaborating Centre for Reference and Research on Salmonella. With regard to new taxonomic knowledge, the traditional classification of 4 Salmonella subgenera was replaced by the concept of 5 subspecies, designated I, II, IIa (monophasic Arizona), IIIb (diphasic Arizona), IV and V. Furthermore, names of serovars belonging to subspecies I are no longer printed in italics, indicating their infrasubspecific rank. Twenty serovars belong to subspecies I, 26 to II, 1 to subspecies IIIa, 3 to subspecies IIIb, 1 to subspecies IV and 1 to subspecies V.
