Methodological choices in brucellosis burden of disease assessments: A systematic review

Most studies retrieved brucellosis epidemiological data from administrative registries. Incidence data were often estimated on the basis of laboratory-confirmed tests. Not all studies included mortality ...

Welfare-Adjusted Life Years (WALY): A novel metric of animal welfare that combines the impacts of impaired welfare and abbreviated lifespan.

animal welfare, the probability of an incident case developing and impaired welfare weights, representing the degree of impaired welfare. The years of life lost are calculated using the standard expected ...

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 ...

Vers un monitoring des facteurs de risque d'émergence des maladies animales?

the geographical expansion of the pathogen, the asymptomatic carriage, the increase in incidence of the disease in other countries and epidemiological role of wildlife. These seven risk factors had also ...

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.

associated with 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 ...

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 ...
