A. Dekker et C. Terpstra, SAMPLE COLLECTION IN A SVD SURVEILLANCE P ROGRAM - AN EPIDEMIOLOGIC VIEW, Tijdschrift voor diergeneeskunde, 121(12), 1996, pp. 347-349
Periodic (4-monthly) surveillance of pig herds for antibodies against
swine vesicular disease (SVD) is obligatory in the Netherlands since 1
993. Samples should be collected 'at random' in as many compartments a
s possible, with a maximum of one pig per pen. This prerequisite for a
sensitive surveillance will be elucidated using four examples of SVD
outbreaks in the Netherlands.
