Distinction between persistent and transient infection in a bovine viral diarrhoea (BVD) control programme: appropriate interpretation of real-time RT-PCR and antigen-ELISA test results.
to assess the performances of diagnostic assays used in the testing scheme for BVD as proposed by the two Belgian regional laboratories. Individual blood samples were collected from 4972 animals, and ...
Towards a typing strategy for Arcobacter species isolated from humans and animals and assessment of the in vitro genomic stability.
or strategy has been proposed. Therefore, after the validation of PFGE, those commonly applied typing methods were compared for the characterization of six human- and animal-associated Arcobacter ...
Association between variables used in the field substitution and post-stratification adjustment in the Belgian health interview survey and non-response.
Young adult Abstract: OBJECTIVES: Field substitution and post-stratification adjustment have been proposed to reduce non-response bias in population surveys. We investigated if variables involved in those ...
Human papillomavirus prevalence and type-distribution, cervical cancer screening practices and current status of vaccination implementation in Central and Eastern Europe.
