Sir.—Although I found your recent editorial helpful, there was a discrepancy between your editorial1 and the statements contained in the articles by Baumgartner et al2 and Enzenauer and Bass.3 In the articles, there is no mention of the type or types of Hemophilus influenzae observed, while you state that both groups found H influenzae type b. Perhaps this discrepancy was the result of copy editing, but it seems more likely that there was another reason for the omission of H influenzae type b from the articles.
It has previously been noted in reports of neonatal sepsis caused by H influenzae that type b is infrequently implicated.4,5 This has implications not only for early diagnosis using countercurrent immunoelectrophoresis or latex particle agglutination (since only antiserum to type b is available) but also for treatment, since it is not at all clear what percentage of nontype b
