Abstract
The presence of a temperate phage was demonstrated in a strain of Vibr io cholerae O139 isolated from a patient. Spontaneous variants with tr anslucent colonies had lost this phage. The loss of the Phage was asso ciated with increased hydrophobicity, indicating the loss of the capsu le. These clones were sensitive to serum bactericidal activity, showed decreased expression of such presumed virulence factors as proteases, motility and mannose-sensitive pill. Furthermore, excision of the pha ge made the strain dependent on purines for growth.
