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 ...
Classical swine fever virus is genetically stable in vitro and in vivo.
genetic stability on phylogenetic examinations, the Belgian field isolate Wingene’93 was passaged in pigs as well as in cell culture by various methods. Sequence analyses of viruses collected after various ...
Epidemiologic, pathogenic and molecular analysis of recent encephalomyocarditis outbreaks in Belgium.
offspring of a sow with reproductive failure. From August 1995 until December 1996, EMCV was diagnosed in 154 Belgian pig holdings in association with myocardial failure and sudden death in fatteners and ...
Identification of encephalomyocarditis virus in clinical samples by reverse transcription-PCR followed by genetic typing using sequence analysis.
epidemiology of encephalomyocarditis virus (EMCV) infections in pigs by applying molecular techniques. The diagnostic potential of a reverse transcription- PCR (RT- PCR) targeting 286 nucleotides at the 3’ end ...
High-level expression of Chlamydia psittaci major outer membrane protein in COS cells and in skeletal muscles of turkeys.
of the avian C. psittaci serovar D strain NJ1, 79.1 and 81.1% identical to that of the C. psittaci guinea pig inclusion conjunctivitis strain, 60.9 and 62.5% identical to that of the Chlamydia ...

Detection of foot-and-mouth disease by reverse transcription polymerase chain reaction and virus isolation in contact sheep without clinical signs of foot-and-mouth disease.
sentinel pigs. This indicates that serologically positive contact sheep without clinical signs may be considered as a danger for the transmission of FMDV. Health Topics: Animal health Category: A1 FOS ...
An experimental infection with classical swine fever virus in weaner pigs. I. Transmission of the virus, course of the disease, and antibody response.
isolated in the first CSF infected herd of the 1993-1994 Belgian epizootic, was examined in an isolation unit with three adjacent pens and 15 weaner pigs per pen. Virus was introduced through experimental ...
An experimental infection with a classical swine fever virus in weaner pigs. II. The use of serological data to estimate the day of virus introduction in natural outbreaks.
a companion paper a logistic regression model of seroprevalence over time was developed on the basis of data obtained during an experimental infection of weaner pigs with classical swine fever (CSF) virus. The ...
