SASd wird als wirtsassoziiert mit geringer Virulenz betrachtet. Ziel\n                    der Studie war es, den Zeitpunkt des ersten SASd-Nachweises bei L\u00e4mmern\n                    nach der Geburt sowie eine dabei bestehende Abh\u00e4ngigkeit vom\n                    Infektionsstatus des Mutterschafes zu ermitteln.<\/jats:p>\n                  <jats:p>Material und Methoden  Kottupfer und Nasentupfer von 88 Mutterschafen aus\n                    einer Herde mit bekanntem SASd-Status jedoch unbekannter\n                    Intraherdenpr\u00e4valenz wurden 6 Wochen vor Beginn der Ablammperiode auf\n                    SASd untersucht. Von je einem weiblichen Lamm dieser Mutterschafe wurden\n                    ebenfalls Kottupfer und Nasentupfer an 4\u20136 Zeitpunkten zwischen dem 4.\n                    und 50. Lebenstag (LT) sowie im Alter von 7, 30 und 40 Monaten auf SASd\n                    untersucht.<\/jats:p>\n                  <jats:p>Ergebnisse  In den ersten beiden Wochen nach der Geburt wiesen deutlich\n                    mehr L\u00e4mmer einen positiven Befund im Nasentupfer als im Kottupfer auf,\n                    wobei vor allem bei L\u00e4mmern von Muttern mit positivem Nasentupfer\n                    ebenfalls SASd auf der Nasenschleimhaut nachgewiesen wurde. 43 L\u00e4mmer\n                    blieben bis zum 50. Tag SASd-negativ, es bestand keine Abh\u00e4ngigkeit vom\n                    Infektionsstatus des Muttertiers. Mit 7 Lebensmonaten erh\u00f6hte sich die\n                    Zahl der Tiere mit einem positiven Nachweis von SASd deutlich. Aus 32%\n                    der untersuchten Nasentupfer und 62% der Kotproben konnte SASd isoliert\n                    werden.<\/jats:p>\n                  <jats:p>Schlussfolgerungen  Es erfolgt keine schnelle und intensive\n                    \u00dcbertragung von SASd von Mutterschafen auf deren Nachkommen. Die\n                    Infektion beginnt mit hoher Wahrscheinlichkeit durch die Kolonisierung der\n                    Nasenschleimhaut der L\u00e4mmer und verursacht keine klinische\n
