Environmental prevalence of toxigenic Vibrio cholerae O1 in Bangladesh coincides with V. cholerae non-O1 non-O139 genetic variants which overproduce autoinducer-2.

PLoS ONE, 2021
Prevalence of toxigenic Vibrio cholerae O1 in aquatic reservoirs in Bangladesh apparently increases coinciding with the occurrence of seasonal cholera epidemics.

Rapid tests as a practical alternative to slide agglutination for the confirmation of <i>V. cholerae</i> O1. [PDF]

J Clin Microbiol
ABSTRACT Slide agglutination for serogroup and/or serotype identification is a crucial step for confirming cholera by culture. Rapid diagnostic tests (RDTs) are typically used directly on stool but are not considered sufficient for cholera confirmation. However, they may provide a practical alternative

Bivalent oral cholera vaccination induces a memory B cell response to the V. cholerae O1-polysaccharide antigen in Haitian adults. [PDF]

PLoS Negl Trop Dis, 2019
The bivalent killed whole-cell oral cholera vaccine (BivWC) is being increasingly used to prevent cholera. The presence of O-antigen-specific memory B cells (MBC) has been associated with protective immunity against cholera, yet MBC responses have not been evaluated after BivWC vaccination. To address this knowledge gap, we measured V.

Vibrio cholerae serotype impacts pathogenicity [PDF]

Nature Communications
The O1 serogroup of Vibrio cholerae has caused all cholera pandemics and for over a century V. cholerae O1 outbreak strains have been characterized by their serotype. The two V.

Quorum Sensing Regulation of the Two hcp Alleles in Vibrio cholerae O1 Strains [PDF]

PLoS ONE, 2009
BACKGROUND:The type VI secretion system (T6SS) has emerged as a protein secretion system important to several gram-negative bacterial species. One of the common components of the system is Hcp, initially described as a hemolysin co-regulated protein in a

Identity of hemolysins produced by Vibrio cholerae non-O1 and V. cholerae O1, biotype El Tor [PDF]

Infection and Immunity, 1986
Hemolysins purified from non-O1 Vibrio cholerae (non-O1 hemolysin) and a Vibrio cholerae O1, biotype El Tor (El Tor hemolysin) were investigated for their homology. The hemolysins were isolated from the culture supernatant fluids by ammonium sulfate precipitation and gel filtration on Sephadex G-100 columns.
