Pathogenesis of encephalomyocarditis experimental infection in young piglets: a potential animal model to study viral myocarditis.
as negative controls and were euthanised at hour 0. The remaining 24 were euthanised every 6 h up to 78-h post infection (hpi). Virus isolation, histological examination and EMCV immunodetection were ...
Transmission of encephalomyocarditis virus in pigs estimated from field data in Belgium by means of R0.
twice and their serum was tested in a virus neutralisation test. Seroprevalence at the first and second sampling was 41 and 43% respectively, with a cut off value of 1:40. R0 was estimated for ...
Association of Streptococcus gallolyticus strains of high and low virulence with the intestinal tract of pigeons.
and ligatures were placed at the beginning of duodenum, jejunum, ileum, and colon. The obtained intestinal loops of the birds of the first and second group were injected with S. gallolyticus strains STR ...
Resistance mechanism against fluoroquinolones in Mycoplasma hyopneumoniae field isolates.
In all five resistant isolates, one point mutation (C-→ A) in parC was found, resulting in an amino acid change from serine to tyrosine at position 80 (Escherichia coli numbering). For four of these ...
Sensitivity of avian Eimeria spp. to seven chemical and five ionophore anticoccidials in five Belgian integrated broiler operations.
of three Ross chicks. Medication started at 8 days of age, and each inoculated bird received 50,000 sporulated oocysts at 10 days. Results were related to the anticoccidial program that had been in ...
Dietary silver nanoparticles can disturb the gut microbiota in mice.
microbiota in mice at doses relevant for currently estimated human intake. METHODS: Mice were orally exposed to food (pellets) supplemented with increasing doses of Ag NP (0, 46, 460 or 4600 ppb) during 28 d. ...
Comparative Analysis of Different Serological and Molecular Tests for the Detection of Small Ruminant Lentiviruses (SRLVs) in Belgian Sheep and Goats.
infection before seroconversion at two weeks post infection and showed a specificity of 100%. Sensitivity however remained suboptimal at 85%. These results allow to propose a faster and cheaper diagnostic ...

virus (CBPV) and deformed wing virus A (DWV-A) were prevalent to a lower extent (between 18 and 29%). Most viruses were only present at low or moderate viral loads. Nevertheless, about 50% of the colonies ...
Replicative fitness recuperation of a recombinant murine norovirus- reciprocity of genetic shift and drift.
fitness recuperation and genetic characteristics of RecMNV progenies at early and late stages of an adaptation experiment were evaluated. Replicative fitness regain of the recombinant was demonstrated via ...
Transmission of Bluetongue Virus Serotype 8 by Artificial Insemination with Frozen-Thawed Semen from Naturally Infected Bulls.
negative heifers were hormonally synchronized and artificially inseminated at oestrus. In total, six groups of three heifers received semen from four batches derived from three bulls naturally infected with ...
