The presence of bluetongue virus serotype 8 RNA in Belgian cattle since 2008.
period and the circulation of bluetongue virus in cattle populations in Belgium since the introduction of vaccination programmes. Overall, the results presented here show evidence for the long-term ...
Effect of coated and non-coated fatty acid supplementation on broiler chickens experimentally infected with Campylobacter jejuni.
period (1-42 days), the chickens were fed a diet supplemented with 0.25% caprylic and capric acid (1:1), coated or non-coated. At the age of 14 and 28 days, chickens were orally challenged with C. jejuni. ...
Susceptibility of pigeons to clade 1 and 2.2 high pathogenicity avian influenza H5N1 virus.
collected, and sera were tested using hemagglutination inhibition (HI) test and blocking enzyme-linked immunosorbent assay (bELISA). During the observation period all pigeons remained clinically healthy, and ...
Persistence of free-living protozoan communities across rearing cycles in commercial poultry houses.
broiler houses across consecutive rearing cycles. Various free-living protozoa (flagellates, ciliates, and amoebae), including known vectors of bacterial pathogens, were observed during the down periods in ...
The impact of naturally-occurring, trans-placental bluetongue virus serotype-8 infection on reproductive performance in sheep.
and 26 aborted fetuses from 300 ewes, lambing at four distinct time periods, were investigated between November 2007 and May 2008. The following evidence suggested that BTV-8 infection occurred in ...
Haemorrhagic diathesis in neonatal calves: an emerging syndrome in Europe.
Flanders, 84 cases of neonatal HD in 30 herds were reported in this period. The disease typically affects calves younger than 1 month old from different breed and gender. Prominent clinical signs are ...
H5N1 high pathogenicity avian influenza virus survival in different types of water.
twice a week over a 60-day trial period by microtiter endpoint titration. The persistence of the virus varied considerably depending on its concentration and also on physico-chemical parameters of the ...
Proof of concept for the reduction of classical swine fever infection in pigs by a novel viral polymerase inhibitor.
piglets. The compound, administered in feed, was readily bioavailable and was well tolerated. Eight specific-pathogen-free pigs received a daily dose of 75 mg kg(-1) (mixed in feed) for a period of 15 ...
Bioaugmentation of microbial communities in laboratory and pilot scale sequencing batch biofilm reactors using the TOL plasmid.
transconjugant cells were detected in the laboratory scale reactor where the ratio of transconjugants to donors fluctuated between 1.9 x 10(-1) and 8.9 x 10(-1) during an experimental period of 32 days. BA ...
Diversity and habitat specificity of free-living protozoa in commercial poultry houses.
(denaturing gradient gel electrophoresis [DGGE]) on natural samples, we show that, despite strict hygiene management, free-living protozoa are common and widespread throughout a 6-week rearing period in both ...
