CTXφ Bacteriophage : ウィキペディア英語版 | CTXφ Bacteriophage The CTXφ bacteriophage is a filamentous bacteriophage that contains the genetic material needed by the ''Vibrio cholerae'' bacterium for the production of cholera toxin, or CT. CTXφ is a positive virus with single-stranded DNA (ssDNA). ==Genetic Material== CTXφ is generally present as an integrated section of the genome of the V. cholerae bacterium, and more rarely in a virion form outside the bacterium. While integrated into the bacterial genome, the CTX prophages are found on each of the two chromosomes (O1 serogroup of ''V. cholerae'') or arranged tandemly on the larger chromosome of bacterium (El Tor biotype of V. cholerae). The genome of CTXφ is 6.9 kb long and consists of two regions. The core region contains genes that code for the CT toxin itself as well as some proteins that are presumed to form the outside coat of the virus. The RS2 region contains the genes that control the replication, regulation, and integration of CTXφ.〔
