Transmission of encephalomyocarditis virus (EMCV) among pigs experimentally quantified.
transmission experiments were performed to estimate the basic reproduction ratio R(0), indicating the level of encephalomyocarditis virus (EMCV) transmission among pigs. In a first experimental set-up with nine ...
Patterns of Mycoplasma hyopneumoniae infections in Belgian farrow-to-finish pig herds with diverging disease-course.
and management conditions were good whereas these conditions were poor in the subclinically infected herds. In each herd, serum antibodies against Mh were detected in pigs of different ages and nasal ...
Descriptive epidemiology of a classical swine fever outbreak in the Limburg Province of Belgium in 1997.
a rapid elimination of the CSF virus. A total of 46,561 pigs were slaughtered to control the spread of the infection. Another 27,579 pigs were slaughtered in the framework of the market support. The total ...
Classical swine fever virus: a second ring test to evaluate RT-PCR detection methods.
CSFV-infected pigs. Each laboratory tested the samples using PCR / RT- PCR according to a set of standardised protocols that specified the exact conditions and requirements for inclusion of control samples. Two ...
An experimental infection with classical swine fever in E2 sub-unit marker-vaccine vaccinated and in non-vaccinated pigs.
protection induced by an E2 sub-unit marker-vaccine against Classical Swine Fever (CSF) was examined during an experimental infection in vaccinated and non-vaccinated pigs. Forty-five pigs were equally ...
Classical swine fever virus: a ring test to evaluate RT-PCR detection methods.
viral RNA representative of seven different genetic subtypes of CSFV. The other set comprised 40 clinical samples containing tonsil, spleen, whole blood or serum from a pig that had been experimentally ...
Effects of inhalation of dust and endotoxin on respiratory tracts of pigs.
of inhalation of feed flour dust and dustborne endotoxin on respiratory tracts of pigs. ANIMALS: 29 healthy Belgian Landrace pigs. PROCEDURE: Pigs housed in an environmental chamber were exposed for ...
Experimental infection of slaughter pigs with classical swine fever virus: transmission of the virus, course of the disease and antibody response.
fever virus was investigated in an isolation unit containing four pens, each containing six slaughter pigs. One pig in the middle pen of three adjacent pens was inoculated intramuscularly and intranasally ...
Prevalence of herds with young sows seropositive to pseudorabies (Aujeszky's disease) in northern Belgium.
a true PRV within-herd prevalence of 43%, the overall true PRV herd prevalence was estimated to be 35%. A logistic multiple-regression revealed that the presence of finishing pigs was associated with ...
Phylogenetic analysis of European encephalomyocarditis viruses: comparison of two genomic regions.
The phylogenetic relationships of encephalomyocarditis (EMC) viruses isolated from pigs and rodents in Europe were determined by comparison of nucleotide sequences from two different regions of the ...
