L'agente patogeno Staphylococcus aureus rappresenta una minaccia per la detenzione di bestiame lattiero e la produzione casearia poiché causa elevate perdite finanziarie nell’ambito del bestiame da latte: il latte crudo trasformato in formaggi, infatti, può causare problemi di indigestione. Un nuovo test genetico sviluppato da Agroscope può rilevare in modo affidabile la presenza dell'agente patogeno nei campioni di latte. Il test genetico fornisce quindi la base per il risanamento di greggi in cui compare l'agente patogeno e contribuirà a ridurre l’utilizzo di antibiotici.
