A hex mutant of Haemophilus influenzae.

Abstract

A mutant of Haemophilus influenzae which does not discriminate between low efficiency (LE) and high efficiency (HE) markers has been isolated. The mutant does not differ wild type in its sensitivity to ultraviolet radiation, methyl methanesulfonate (MMS) mitomycin C, and nitrous acid. Spontaneous mutation frequencies for three loci studied are 10- to 30-fold higher in the mutant than in the wild type strain. Low- and high-efficiency transforming markers are equally UV-resistant when assayed on this mutant. This mutant is thus similar to the hex mutant of Streptococcus pneumoniae.
