Crosses between P + V. cholerae eltor and P-classical strain of V. cholerae did not give rise to genetic recombinants under normal conditions. Chromosomal mobilization could be induced in P + el tor cells by exposure to 44.degree.-48.degree. C prior to mating. Kinetic study on recombinant formation revealed that efficiency of conjugation induced by heat was a function of temperature and time of incubation. The highest number of recombinants were observed at 46.degree. C, pre-incubated for 20 min.
