Vibrio cholerae haemolysin: genetic constitution and biotype
voltage-gated K channels in other cell types [Ba 2 mM; Cs 5 mM; TEA (tetraethylammonium) 20 mM; EGTA 1 mM) (Lew & Ferreira, 1978; Egan et ul., 1987) did not, however, alter ouabainand bumetanide-insensitive K uptake. The substitution of CH,SO, for CI in the incubation medium reduced the residual K uptake by about 18%, suggesting that a Cldependent K transport pathway similar to that observed in...
متن کاملImmune response genes modulate serologic responses to Vibrio cholerae TcpA pilin peptides.
Cholera is an enteric disease caused by Vibrio cholerae. Toxin-coregulated pilus (TCP), a type 4 pilus expressed by V. cholerae, is a cholera virulence factor that is required for host colonization. The TCP polymer is composed of subunits of TcpA pilin. Antibodies directed against TcpA are protective in animal models of cholera. While natural or recombinant forms of TcpA are difficult to purify...

متن کاملIdentity of hemolysins produced by Vibrio cholerae non-O1 and V. cholerae O1, biotype El Tor.
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. The purified hemolysins gave single bands with an identical mobility on conventional po...
