Benign Vibrio cholerae becomes pathogenic by all of the following steps except

Question

Quizplus · Accepted Answer

The option E is incorrect because bacteriophages do not specifically bind only to benign Vibrio cholerae without pili. The correct statement is that the bacteriophage CTXφ specifically infects Vibrio cholerae bacteria that are capable of producing pili, which is an essential requirement for the bacteria to become pathogenic. The bacteriophage integrates its DNA, including the cholera toxin gene, into the host chromosome, which leads to the production of the cholera toxin and the transformation of the benign host into a disease-causing agent. Therefore, options A, B, C, and D are correct steps involved in the transformation of benign Vibrio cholerae into pathogenic Vibrio cholerae by the bacteriophage CTXφ.
