Summary<\/span>
The aim of a cross-sectional survey performed between November 2005 and April 2006 was to obtain actual information on the occurrence of Neospora (N.) caninum<\/span> infection in dairy cows of Schleswig-Holstein. It was planned to examine tank-milk of about 35% of the approximately 6,000 dairy herds in Schleswig-Holstein for N. caninum<\/span>-specific antibodies using a p38-tank-milk ELISA. This test is able to detect a within-herd N. caninum<\/span>-seroprevalence of gt; 10%. Only 20 (1.0%) out of 1,950 tank-milk samples from Schleswig-Holstein reacted N. caninum<\/span>-positive. A significantly higher proportion of positive herds came from districts with a human population density gt; 125 per km2 (P = 0.022, Fisher exact test). These districts were located close to the city of Hamburg. A prior survey in Rhineland- Palatinate performed with the same ELISA had revealed a proportion of 7.9 % of tank-milk-positive herds. The results of the present survey therefore confirm prior assumptions that N. caninum <\/span>infections are variably distributed in different German federal states. Similar to the results obtained in Rhineland-Palatinate, the observation of positive herds in the present study was associated with an elevated population density.

Ziel einer von November 2005 bis April 2006 durchgef\u00fchrten Querschnittstudie war es, aktuelle Informationen \u00fcber das Vorkommen von Neospora (N.) caninum<\/span>- Infektionen bei Milchk\u00fchen in Schleswig-Holstein zu erhalten. Es wurde angestrebt, Tankmilchproben von etwa 35 % der ca. 6000 Milchkuhbetriebe in Schleswig-Holstein mittels eines p38-Tankmilch-ELISA auf N. caninum-<\/span>spezifische Antik\u00f6rper zu untersuchen. Dieser ELISA ist zum Nachweis von Herden mit einer N. caninum-Seropr\u00e4valenz von gt; 10 % geeignet.
