Vibrio virus CTXphi

The CTXφ bacteriophage is a filamentous bacteriophage. It is a positive-strand DNA virus with single-stranded DNA (ssDNA).

CTXφ infects some strains of Vibrio cholerae, the bacterium that causes cholera. It carries the genes for cholera toxin (CTX), which makes cholera especially virulent. It can carry genes from one V. cholerae strain to another.
