[Isolation of Listeria spp. and Aspergillus fumigatus--two case reports from mastitis diagnosis].

Two rare cases of a bovine listeria mastitis and a mould mastitis are being described and discussed. The L. monocytogenes strains isolated from milk as well as silage samples were further genotyped by means of Pulsed-Field Gel Electrophoresis (PFGE) and macrorestriction analysis (ApaI). Three strains from the silage and four strains from quarter milking showed an identical PFGE-pattern.
