Lean tuna meat suspensions (LEAN), with a fat content of 0.006%, and fatty tuna meat suspension (FATTY), with a fat content of 3.0% were inoculated with four strains of Vibrio parahaemolyticus and wasabi (Wasabia japonica Matsumura) or allyl isothiocyanate (AIT) was added before incubation at 37 degrees C. During the incubation, viable Vibrio counts were(More)
Here, we report the enhancing effects of nitric oxide (NO) on an IgE antibody response in mice. Anti-trinitrophenyl (TNP) IgE production induced in vitro in TNP keyhole limpet hemocyanin (KLH)-primed spleen cells was inhibited by approximately 70% when an NO synthase (NOS) inhibitor, L-N(G)-monomethyl-L-arginine, was added at 10(-7)-10(-6) M to the(More)
A soil bacterium, Klebsiella oxytoca TNM3, was found to produce a polysaccharide named AZ9 with immunosuppressive activities. The culture of K. oxytoca in a jar fermentor resulted in an extreme increase in the viscosity of the culture broth (>10,000 mPa.s) due to accumulation of the polysaccharide with a high molecular weight. The molecular weight of AZ9(More)
Baculovirus display systems have been utilized for cell-specific gene transfer, regenerative medicine, and as vaccine vectors. In particular, baculovirus particles displaying surface antigens have been used as vaccines against some parasites and viruses. In this study, Bombyx mori nucleopolyhedrovirus (BmNPV) particles displaying Neospora caninum antigens(More)
Three antigens (NcSAG1, NcSRS2 and NcMIC3) from Neospora caninum were expressed using the BmNPV bacmid system in silkworm larvae and purified from the hemolymph. From 20 silkworm larvae, 1.5, 1.2 and 1.4 mg of purified recombinant NcSAG1, NcSRS2 and NcMIC3 were obtained, respectively. When each purified recombinant antigen was immunized with Freund's(More)
