Full-Genome Sequencing of Four Bluetongue Virus Serotype 11 Viruses.

Serogroup Sheep Vaccination Viral Vaccines Abstract: Recently, a contamination incident was described in which the challenge inoculum used in a bluetongue virus serotype 8 (BTV-8) vaccination trial was ...

Pyrrolizidine alkaloids in food and feed on the Belgian market.

Furthermore, we detected PA s in 4 of 63 commercial milk samples. A high incidence rate of PA s in lucerne (alfalfa)-based horse feed and in rabbit feed was detected, while bird feed samples were less ...

Prediction of respiratory disease and diarrhea in veal calves based on immunoglobulin levels and the serostatus for respiratory pathogens measured at arrival.

with average daily gain (ADG) in the study period. The study population consisted of 150 rosé veal calves housed in a single air-space. The study period ended at day 18 post arrival, when BRD incidence ...

Trends in genotype frequency resulting from breeding for resistance to classical scrapie in Belgium (2006 ˜ 2011).

implemented a breeding program that promotes selection of the ARR haplotype while reducing the incidence of VRQ. From 2006 to 2011 in Belgium, frequency for the ARR / ARR genotypes increased from 38.3% to 63.8% ...

Spatiotemporal dynamics of Puumala hantavirus in suburban reservoir rodent populations.

incidence of human infections during years of large vole populations. This study aimed to better understand the link between virus prevalence in the vector, vole demography, habitat quality, and human ...

Susceptibility of in vitro produced hatched bovine blastocysts to infection with bluetongue virus serotype 8.

an increased incidence of abortion and other reproductive problems. For these reasons, and also because BTV-8 is threatening to spread to other parts of the world, there is a need for more information ...

Bluetongue in Belgium: episode II.

data were analysed. Overall cumulative incidence at herd level was estimated at 11.5 (11.2-11.8) and 7.5 (7.3-7.8) per cent in cattle and sheep populations respectively. The findings went in favour of ...

Impact of human interventions on the spread of bluetongue virus serotype 8 during the 2006 epidemic in north-western Europe.

adopted by the national authorities in Belgium, France, Germany, and The Netherlands. The impact of the control measures on the BTV-incidence in time and space was explored. Data on ruminant transports ...

Possible routes of introduction of bluetongue virus serotype 8 into the epicentre of the 2006 epidemic in north-western Europe.

obtained. Imports originating from countries with a known or suspected history of BTV-incidence of any serotype were identified. The list of countries with a reported history of BTV incidence was obtained ...

Transplacental infection and apparently immunotolerance induced by a wild-type bluetongue virus serotype 8 natural infection.

the use of modified live virus strains. During the 2007 BT epidemic in Belgium, a significant increase in the incidence of abortions was reported. A study including 1348 foetuses, newborns and young ...
