Transduction of staphylococcal enterotoxin B synthesis: establishment of the toxin gene in a recombination-deficient mutant.

Cotransduction of enterotoxin B synthesis into a recombination deficient mutant only occurred when the donor contained the pEntB plasmid. Enterotoxin B from chromosomal genotypes could not be established in such hosts. These data suggest that the entB gene is not capable of high-frequency translocation.
