Some properties of sialic-acid binding systems in Tritrichomonas suis and Tritrichomonas foetus.
Hemagglutination of normal and enzyme-treated red blood cells and its inhibition, in vitro adherence to porcine caecal mucus and kinetic properties of neuraminidase were carried out with Tritrichomonas suis and T. foetus. All tested strains adhered extensively to porcine caecal mucus in vitro and agglutinated human (A1, A2, B and O), rabbit, porcine and hen red blood cells. Different inhibitors were efficacious in hemagglutination activity (HA) tests using neuraminidase treated and untreated red blood cells. The Scatchard plot showed an independent type of cooperativity in porcine strain 41, while in bovine strain KVC-1, a positive type of cooperativity was observed.
