[Haemophilus influenzae biovars in patients with acute and chronic inflammatory lung diseases].
In the study of the biological properties of 175 H. influenzae strains isolated from patients with acute and chronic inflammatory lung diseases (ILD) and from donors, a wide spread of biovars I, II and III (according to Kilian) was revealed; these biovars constituted 80% of the cultures under study. In donors, H. influenzae strains were characterized by a wide spectrum of biovars, but biovars I, II and VI constituted more than a half (64.2%) of the strains obtained in the course of these investigations. In acute ILD, only H. influenzae biovars I, II and III were isolated with the prevalence of biovar II (56.4%). In chronic ILD, all H. influenzae biovars were represented, but biovars II and III prevailed (58.7%). The four-fold difference in the occurrence of H. influenzae strains belonging to undetermined biovars was established in donors in comparison with ILD patients (46.7 +/- 9.8% and 12.0 +/- 2.5%; p less than 0.001).
