Abstract

The antigenic characteristics of the lipooligosaccharide (LOS) of Haemophilus influenzae type b (Hib) were examined in strains obtained over an extended period of time. These Hib strains were isolated from patients with systemic Hib disease in Dallas, Tex., over a 20-year period and in New York City between 1941 and 1956. The antigenic characteristics of the LOS of these Hib strains were examined by using a set of four murine monoclonal antibodies directed against epitopes present in the oligosaccharide portion of the LOS molecule. The same basic set of LOS antigenic determinants that is expressed by recent Hib isolates was also found to be present in this collection of Hib strains spanning a 40-year period. Some variation with time was detected in the distribution of the systemic disease isolates among four Hib LOS antigenic groups; however, only 2 of 188 Hib isolates failed to react with a set of two LOS-specific monoclonal antibodies. Therefore, little variation has occurred among Hib strains with regard to the LOS epitopes defined by these monoclonal antibodies over a considerable period of time.
