[Utilization of a micromethod for the differentiation of Haemophilus biotypes. Relations with serotypes and antibiotypes (author's transl)].
A micromethod utilizing paper discs impregnated with different substrates (Minitek-system) permits differentiation of Haemophilus and their biotypes. Differentiation of biotypes presents an assured advantage: it is the only technic for an exact study of non typable H. influenzae strains and NAD-dependent Haemophilus strains. It is also a complement for study of capsulated H. influenzae. In an epidemiological aspect, this differentiation shows a evident predominance of biotypes I and II for H. influenzae and H. para-influenzae. Except that biotype I includes the larger number of serotypable strains, different serotypes are distributed in the five biotypes of H. influenzae. Likewise none relation has been found between biotypes and antibiotypes.
