✦ Synopsis

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.

A strain of Haemophilus influenzae, called hpm- inhibits the growth of phage HP1c1 but not S2. This inhibition is overcome by HP1c1ph mutants. Phage HP1c1 adsorbs normally to hpm- cells but only a small fraction of infected cells produce phage with a normal burst size or become lysogenic. When hpm-

Vegtative recombination of temperature-sensitive mutants of Haemophilus influezae bacteriophage N3 was measured in wild-type H. influenzae strain Rd9 and in recombination-defective mutants of the Rd strain. Recombinants are formed with low but equal frequency in wild-type cells and recombination-def
