[Vibrio eltor mutants with altered hemolysin production: their isolation and characteristics].

Hemolysin hyper- hypoproductive Vibrio eltor mutants and hemolytically inactive clones were isolated using tetracycline (Tn10) and chloramphenicol (Tn9) resistance transposons. Chromosomal localization was demonstrated for hml gene(s) involved in hemolysin production. Mutations responsible for an altered hemolysin production are likely to be situated closely to pur ura arg met chromosomal markers.
