Tracability in meat processing: The genetic markers212
frequent, stable, randomly scattered and generally biallelic. Their detection is performed either by hybridization on biochips or by mass spectrometry or by other easily automatable technics. This automation ...
Epidemiological support for a multifactorial aetiology of Kashin-Beck disease in Tibet36703
fungal contamination of stored grain and the organic matter content of drinking water. Multivariate analysis was performed using logistic regression and population attributable fractions were computed to ...
First evidence of Johne's disease in farmed red deer (Cervus elaphus) in Belgium.
negative. Direct and indirect tests were performed on 24 hinds and stags (yearlings, 2- and 4-year-old animals). The indirect tests performed were serology (Mycobacterium paratuberculosis antibody ELISA, ...
Cervical cancer screening in Belgium.
performed at yearly intervals. A programme for organised screening — promoting one cervical smear every 3 years for women aged between 25 and 64 years — is being set up in the Flemish Region alone. Important ...
Production of antibodies against chicken interferon-gamma: demonstration of neutralizing activity and development of a quantitative ELISA.
addition to being more rapid and easier to perform than classical cell-mediated immunity tests, this ELISA has excellent sensitivity and improved specificity. The use of a specific rabbit polyclonal serum as ...
Classical swine fever virus: a ring test to evaluate RT-PCR detection methods.
false positive results. Several of the PCR tests appear suitable in terms of specificity and sensitivity. Further trials are necessary to compare results when the same test is performed by different ...
Long-term protection against bovine leukaemia virus replication in cattle and sheep.
viruses and naked DNA injections are able to delay BLV infection, although complete protection cannot be achieved. In addition, our data cast light onto the need to perform long-term vaccination trials ...
Immunogenicity and protective efficacy of DNA vaccines encoding secreted and non-secreted forms of Mycobacterium tuberculosis Ag85A.
