Longitudinal monitoring of Culicoides in Belgium between 2007 and 2011: local variation in population dynamics parameters warrant cautious use of monitoring data.
abundance parameters, no specific sites could however be identified where monitoring consistently showed shorter or longer vector-free periods. CONCLUSIONS: In conclusion, our results show that the selection ...
Differential Viral Fitness Between H1N1 and H3N8 Avian Influenza Viruses Isolated from Mallards (Anas platyrhynchos).
reinfection under controlled experimental conditions. The H1N1 virus had a delayed peak of excretion of 4 days compared to the H3N8, but the virus shedding was more limited, earlier, and shorter after each ...
Impact of a novel inactivated PRRS virus vaccine on virus replication and virus-induced pathology in fetal implantation sites and fetuses upon challenge.
starting from 3 to 7 days postchallenge (1.0 to 5.0 log2). In contrast, the unvaccinated gilts remained negative for VN antibodies after challenge. The vaccinated gilts had shorter viremia than the control ...
Development of a foot-and-mouth disease infection model in severe combined immunodeficient mice for the preliminary evaluation of antiviral drugs.
virus-induced morbidity (including respiratory problems and weight loss) with subsequent mortality. Inoculations with strain A₂₂ Iraq resulted in a reproducible mean time of death of 6 dpi (this was shorter for ...
The positive adjuvant effect of chitosan on antigen-specific cell-mediated immunity after chickens vaccination with live Newcastle disease vaccine.
cellular immune response in digestive tract as shorter when chitosan was used as adjuvant. On the other hand, the chitosan had no effect on the systemic, lachrymal and digestive antibody-mediated immunity. ...
Evaluation of different serologic markers for the early detection of avian influenza infection in chickens.
M2 e antibodies was quite different. Indeed, it was rather shorter and disappeared more rapidly (approximately 35 days postinfection) compared to the kinetics of the other antibodies. Therefore, the ...
Epidemiological characteristics of an outbreak of classical swine fever in an area of high pig density.
the reports of suspect herds generally coincided with increased mortality. The interval between the first occurrence of clinical signs and the report of a suspect herd was shorter when the disease was ...
Experimental transmission of enzootic bovine leukosis to cattle, sheep and goats: infectious doses of blood and incubation period of the disease.
A given inoculum can be infectious in sheep and, at the same time, harmless in cattle. The incubation periods, apparently shorter in sheep, were generally in the range from 2 to 5 weeks for the three ...
Genetic immunisation of cattle against bovine herpesvirus 1: glycoprotein gD confers higher protection than glycoprotein gC or tegument protein VP8.
excretion after challenge. Those calves also excreted virus for significantly (p < 0.05) shorter periods (1.5 days) than the non-vaccinated controls. The other constructs encoding gC and VP8 antigens ...
