Absence of viral envelope proteins in equine herpesvirus 1-infected blood mononuclear cells during cell-associated viremia.
before, were inoculated with EHV-1. PBMC were collected at different time points up to 28 days post inoculation. Ninety-eight percent of the infected PBMC did not show viral envelope proteins on their ...
Vaccination of chicken embryos with escape mutants of La Sota Newcastle disease virus induces a protective immune response.
ovo vaccination. Because antibody responses and protection of in ovo vaccinated chicks were similar to controls vaccinated at hatch with the La Sota strain, immunoselection appears a valuable technique ...
AggA is required for aggregation and increased biofilm formation of a hyper-aggregating mutant of Shewanella oneidensis MR-1.
mutation with the vector pCM62, expressing the aggA gene, this effect could be nullified and biofilm formation was restored to at least the level of the MR-1 wild-type. Health Topics: Animal health ...
Ochratoxin A and citrinin loads in stored wheat grains: impact of grain dust and possible prediction using ergosterol measurement.
content as a general marker of fungal biomass. Present results suggest that this predictive tool would only be valid for predicting the contamination level of CIT and OTA at reasonable moisture content ...
A novel, highly selective inhibitor of pestivirus replication that targets the viral RNA-dependent RNA polymerase.
approximately 2,000. BPIP was inactive against the hepatitis C virus subgenomic replicon and yellow fever virus but demonstrated weak activity against GB virus. Drug-resistant mutants were at least 300-fold less ...
Estimating the probability of freedom of classical swine fever virus of the East-Belgium wild-boar population.
programmes for classical swine fever (CSF) infection in a wild-boar population, based on the assumption that one would detect at least 5% prevalence in a CSF-infected wild-boar population. This assumption, ...
Ultrastructural changes of the tracheal epithelium after vaccination of day-old chickens with the La Sota strain of Newcastle disease virus.
formation of excess mucus. Activation of goblet cells peaked within 4 days postvaccination. Afterward, the activation levels gradually decreased. At the level of the ciliated cells, a marked increase in the ...
Binding and entry characteristics of porcine circovirus 2 in cells of the porcine monocytic line 3D4/31.
Bound PCV2 VLP s were internalized in 47+/-5.0 % of cells. Internalization was continuous, with 70.5+/-9.7 % of bound PCV2 VLP s internalized at 360 min post-incubation. Internalizing PCV2 VLP ...
Virulence-associated traits in avian Escherichia coli: comparison between isolates from colibacillosis-affected and clinically healthy layer flocks.
characteristics of avian pathogenic Escherichia coli associated with the occurrence of colibacillosis outbreaks at flock level. Forty E. coli strains originating from layers from healthy flocks (‘control ...
Arcobacter cibarius sp. nov., isolated from broiler carcasses.
catalase, oxidase and urease activities; reduction of nitrate; growth at 25 and 37 degrees C under aerobic conditions; growth on 2-4 % (w/v) NaCl media; and susceptibility to cephalothin. These data ...
