Validation of two real-time RT-PCR methods for foot-and-mouth disease diagnosis: RNA-extraction, matrix effect, uncertainty of measurement and precision.
not performed or reported generally. In this study, different RNA-extraction procedures were compared for two FMDV rRT- PCR s. The NucleoSpin columns available commercially combined high extraction ...

Epidemiological study of bovine norovirus infection by RT-PCR and a VLP-based antibody ELISA.
diarrhoeic calves screened by RT- PCR. Nucleotide sequencing performed on the polymerase region classified all the norovirus amplicons in the bovine norovirus genotype 2. Rather surprisingly, some rotavirus ...
Analysis of 13 million individual patient records pertaining to Pap smears, colposcopies, biopsies and surgery on the uterine cervix (Belgium, 1996-2000).
cervical biopsies and surgery, performed in Belgium between 1996 and 2000. Cervical cancer screening coverage was defined as the proportion of the target population (women of 25-64 years) that has had a Pap ...
