Non-typable Haemophilus influenzae from a single hospital: epidemiological markers.
A total of 51 strains of non-typable Haemophilus influenzae isolated from a single hospital were subjected to analysis of biochemical traits, outer membrane protein (OMP) profiles, lipopolysaccharide (LPS) electrophoresis and antibiotic susceptibility determination in order to establish a method for bacterial typing. Results proved that none of the methods tested were useful for typing purposes, although the data showed that (1) OMP profiles were extremely variable; (2) LPS profiles were uniform; (3) the multiresistant strains manifested different resistance patterns; and (4) biochemically, all strains were closely related.
