Immunogenicity of recombinant Lactobacillus plantarum NC8 expressing goose parvovirus VP2 gene in BALB/c mice
Goose parvovirus (GPV) continues to be a threat to goose farms and has significant economic effects on the production of geese. Current commercially available vaccines only rarely prevent GPV infection. In our study, Lactobacillus (L.) plantarum NC8 was selected as a vector to express the VP2 gene of GPV, and recombinant L. plantarum pSIP409-VP2/NC8 was successfully constructed. The molecular w...
متن کاملOral Administration of Lactobacillus plantarum Strain AYA Enhances IgA Secretion and Provides Survival Protection against Influenza Virus Infection in Mice
The mucosal immune system provides the first line of defense against inhaled and ingested pathogenic microbacteria and viruses. This defense system, to a large extent, is mediated by the actions of secretory IgA. In this study, we screened 140 strains of lactic acid bacteria for induction of IgA production by murine Peyer's patch cells. We selected one strain and named it Lactobacillus plantaru...
متن کاملProtective immunity against influenza H5N1 virus challenge in chickens by oral administration of recombinant Lactococcus lactis expressing neuraminidase
BACKGROUND Highly pathogenic H5N1 avian influenza viruses pose a debilitating pandemic threat in poultry. Current influenza vaccines predominantly focus on hemagglutinin (HA) which anti-HA antibodies are often neutralizing, and are used routinely to assess vaccine immunogenicity. However, Neuraminidase (NA), the other major glycoprotein on the surface of the influenza virus, has historically se...
متن کاملProduction of monoclonal antibodies against recombinant nucleoprotein of avian influenza virus, serotype H9N2
Background: Avian influenza viruses (AIVs) including the subtype H9N2 cause considerable financial losses to poultry industries. Rapid and accurate diagnosis of avian influenza (AI) infection is important in control and eradication programs. OBJECTIVES: The aim of this study was to produce monoclonal antibodies (MAbs) specific for the nucleocapsid protein )NP (of AIV H9N2 subtype to improve dia...
متن کاملOral administration of heat-killed Lactobacillus plantarum strain b240 protected mice against Salmonella enterica Serovar Typhimurium.
The purpose of this study was to investigate the effects of heat-killed Lactobacillus plantarum strain b240 (b240) on systemic infection by Salmonella enterica serovar Typhimurium (S. Typhimurium) and to determine the mechanism by which b240 protects against infection. Mice were administered either b240 or saline orally for 3 weeks, and then inoculated with S. Typhimurium. The mice treated with...
