Lacunae were produced in lawns of non-O1 V. cholerae indicator strains under the same assay conditions as those where lacunae were produced by the well characterized P fertility plasmid of V. cholerae O1 and the V fertility factor found in a non-cholera vibrio strain. The origin of the lacunae produced by strains habouring the V and L factors was examined. No vibriocin or phage activity was found in culture supernates or in lacunae produced by the strains, suggesting that, as in the case of the P plasmid, the lacunae probably represent sites of active mating. Unlike the P plasmid, neither the Vn or L factor could be detected or isolated by conventional plasmid techniques. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-132-4-1027
