Plaque morphology of different vibriophages on lawns of susceptible V. cholerae strains. Description of phages and host strains are as follows: JSF1 phage plated on a V. cholerae O1 clinical strain isolated from the recent epidemic (A), JSF2 phage isolated from water (B) and from a lysogenic non-O1/non-O139 strain (G) plated on an epidemic V. cholerae O1 strain, JSF3 phage plated on a V. cholerae O139 clinical strain (C), JSF6 phage plated on a V. cholerae O1 strain (F) and an environmental non-O1/non-O139 strain (H), JSF6 phage produced from an environmental non-O1/non-O139 strain and plated on a clinical V. cholerae O1 strain (E), and JSF4 phage plated on a V. cholerae O1 strain (D).
