From C.S. Gowans, University of Missouri, March 1983, his strain C 22-4
This mutant, which is resistant to neamine, was isolated in cells grown on 2-amino-3-phenylbutanoic acid (and is probably resistant to that compound also) prior to plating on neamine. It shows Mendelian inheritance (i.e. is in a gene encoded in nuclear DNA).

This motility mutant was isolated and described by Lewin. Both mating types can mate with other strains, but + and – strains both carrying this mutation do not mate well with each other. Flagella are slow to regenearte after deflagellation. This mutant is also in the collection as CC-957 and CC-2522.
