Two alternative inocula to reproduce bluetongue virus serotype 8 disease in calves.
between days 7 and 31 PI. Humoral immune response developed earlier in calves infected with low cell-passaged virus, while in both groups a massive antibody production was confirmed by the immune balance ...
Intranasal DNA vaccination induces potent mucosal and systemic immune responses and cross-protective immunity against influenza viruses.
induction of potent virus-specific immune responses at mucosal surfaces where virus transmission occurs is a major challenge for vaccination strategies. In the case of influenza vaccination, this has been ...
Epidemiology of Pestivirus infection in wild ungulates of the French South Alps.
strains), rather than BDV-4, a strain responsible for Pyrenean-chamois epizooties. Virus neutralization tests confirm a BDV circulation in wild ungulates in the French South Alps. However, no Pestivirus RNA ...
Classical swine fever: comparison of oronasal immunisation with CP7E2alf marker and C-strain vaccines in domestic pigs.
antibody ELISA and virus neutralisation tests, seroconversion first occurred at 11dpv in the C-strain vaccinated group and between 11 and 15dpv in the CP7E2 alf vaccinated group. The serological response was ...
The positive adjuvant effect of chitosan on antigen-specific cell-mediated immunity after chickens vaccination with live Newcastle disease vaccine.
Newcastle Disease Newcastle disease virus Spleen Viral Vaccines Abstract: The development of safe, novel strong adjuvants is necessary to maximize the efficacy of and the immune response induced by new and/or ...
Development of specific enzyme-linked immunosorbent assays to evaluate the duck immune response after experimental infection with H5N1 and H7N1 low pathogenic avian influenza viruses.
wild ducks as vectors of avian influenza viruses (AIV s) is well known but the immune response induced by AIV has different patterns according to the species of duck. The local antibody produced on the ...
Evaluation of different serologic markers for the early detection of avian influenza infection in chickens.
evaluation of the degree of adaptation and the timing of infection. Therefore, several experimental infections of specific-pathogen-free chickens were conducted to follow the kinetics of antibody responses ...
Improved vaccination against Newcastle disease by an in ovo recombinant HVT-ND combined with an adjuvanted live vaccine at day-old.
live ND vaccine co-administrated or not with chitosan by oculo-nasal route. The induced vaccinal immune responses and conferred protection against a challenge with a circulating NDV velogenic ...
Induction of Mx and PKR failed to protect chickens from H5N1 infection.
response in chickens after hpH5N1 infection, or how the virus is evolving to modify and evade host protective responses. Therefore, to better understand the chicken immune response following hpH5N1 ...
Prior infection with an H1N1 swine influenza virus partially protects pigs against a low pathogenic H5N1 avian influenza virus.
s), but cross-reactive neuraminidase inhibition (NI) antibodies and cell-mediated immune (CMI) responses are common. These immune responses result largely from infections with seasonal human H1N1 ...
