Infectious Serotyping Time Factors Abstract: As a result of a BVDV infection in a herd consisting of 95 adult cattle 17 cows aborted their calves within a period of 3.5 months, one third got severe diarrhoea, ...
Evaluation of virulence of Mycoplasma hyopneumoniae field isolates.
different swine herds. Further studies are required to determine whether the 5000 bp fragment obtained in the RAPD analysis can be used as a virulence marker. Health Topics: Animal health Category: A1 FOS ...
Real-time PCR for simultaneous detection and genotyping of bovine viral diarrhea virus.
viruses (BVDV) occur in Belgian herds, their differentiation is important for disease surveillance. A quantitative real-time PCR assay was developed to detect and classify bovine viral diarrhea viruses in ...
Risk analysis of the spread of classical swine fever virus through "neighbourhood infections" for different regions in Belgium.
herds (P=0.055) [Interactive spatial data analysis. Pearson Education Limited, Harlow, Essex], i.e. the higher the kernel estimation, the higher the risk for the occurrence of neighbourhood infections. In ...
Salmonella on pig carcasses: positive pigs and cross contamination in the slaughterhouse36717
data was poor, because of recent Salmonella infections, a better correlation was found at the herd level on the moment of slaughtering. CONCLUSION: A high degree of carcass contamination is noticed after ...
Patterns of Mycoplasma hyopneumoniae infections in Belgian farrow-to-finish pig herds with diverging disease-course.
Abstract: Patterns of Mycoplasma hyopneumoniae (Mh) infections were investigated in five clinically infected herds and in five herds subclinically infected with Mh. In the clinically infected herds, housing ...
Descriptive epidemiology of a classical swine fever outbreak in the Limburg Province of Belgium in 1997.
eight herds, located in three different areas, were confirmed to be CSF-positive. CSF virus was transmitted from the primary infected herd of one area to another five herds in the same area and to one ...
Production of bovine herpesvirus type 1-seronegative latent carriers by administration of a live-attenuated vaccine in passively immunized calves.
BHV-1-free herds or countries. This study demonstrates that SNLC s can be easily obtained by inoculation with a live-attenuated BHV-1 under passive immunity and that latent carrier animals without any antibody ...
