FIG. 3.

RFLP analysis of the 150-kb plasmid isolated from V. cholerae O1 strains isolated during cholera outbreaks in Guinea-Bissau. The explanations of the lanes include the strain designation and RFLP type unless stated otherwise. Lanes: a, HindIII-digested phage lambda DNA (weight marker); b, reference strain 1075/25; c, F2189, type E; d, F2196, type F; e, 9862, type A; f, 9868, type D; g, C230, type D; h, C231, type D; i, C233, type D; j, C235, type D; k, C236, type D; 1, C240, type D; m, HindIII-digested phage lambda DNA (weight marker).
