Spatial patterns in surveillance data during control of Salmonella Dublin in bovine dairy herds in Jutland, Denmark 2003-2009.

摘要: Salmonella Dublin is the most commonly isolated serotype in Danish cattle and leads to economic welfare losses infected herds. Furthermore, it high mortality human cases. A national surveillance program for was initiated Denmark October 2002. This study aimed at modelling progress spatial patterns during control of dairy herds Jutland peninsula Denmark, especially differences between regions years. total 6331 were included 2003-2009. Antibody measurements bulk-tank milk samples used testing herd-level status these Risk maps estimated as prevalence intensity maps. Spatial clustering analysed using scan statistics SMR estimated. In 2003, test-positive 24%. It decreased 12% 2009. Prevalence showed large reduction The number clusters reduced period. However, throughout period two remained significant. Differences seen over implementation effectiveness different regions. vary not only regions, but also time influencing infection dynamics. Thus, recommendations regionally targeted efforts campaigns are needed.
