Bacteriocin Typing of Vibrio cholerae.
Bacteriocins of Vibrio cholerae have been demonstrated against enterobacterial and vibrio indicator organisms by conventional techniques. Abundant bacteriocin production took place on casein hydrolysate-yeast extract, tryptic soy, digest broth, proteose-peptone, and neopeptone agars. Essential factors were a citrate-phosphate buffer concentration of 0.5 to 0.7%, at pH 7.5 to 7.6, and cold shock...
متن کاملO antigen is the receptor of Vibrio cholerae serogroup O1 El Tor typing phage VP4.
Bacteriophage VP4 is a lytic phage of the Vibrio cholerae serogroup O1, and it is used in phage subtyping of V. cholerae biotype El Tor. Studies of phage infection mechanisms will promote the understanding of the basis of phage subtyping as well as the genetic differences between sensitive and resistant strains. In this study, we investigated the receptor that phage VP4 uses to bind to El Tor s...
متن کاملDevelopment and evaluation of a phage typing scheme for Vibrio cholerae O139.
The scenario of cholera that existed previously changed in 1992 and 1993 with the emergence of toxigenic Vibrio cholerae O139 in India. The genesis of the new serogroup formed the impetus to search for O139 phages in and around the country. A total of five newly isolated phages lytic to V. cholerae O139 strains were used for the development of this phage typing scheme. These phages differed fro...
متن کاملThe Resistance of Vibrio cholerae O1 El Tor Strains to the Typing Phage 919TP, a Member of K139 Phage Family
Bacteriophage 919TP is a temperate phage of Vibrio cholerae serogroup O1 El Tor and is used as a subtyping phage in the phage-biotyping scheme in cholera surveillance in China. In this study, sequencing of the 919TP genome showed that it belonged to the Vibrio phage K139 family. The mechanisms conferring resistance to 919TP infection of El Tor strains were explored to help understand the subtyp...
متن کاملVibrio cholerae typing phage N4: genome sequence and its relatedness to T7 viral supergroup.
OBJECTIVES In countries where cholera is endemic, Vibrio cholerae O1 bacteriophages have been detected in sewage water. These have been used to serve not only as strain markers, but also for the typing of V. cholerae strains. Vibriophage N4 (ATCC 51352-B1) occupies a unique position in the new phage-typing scheme and can infect a larger number of V. cholerae O1 biotype El Tor strains. Here we c...
