Summary
The aim of this pilot prevalence study was to investigate the Oxacillin resistance of 73
Staphylococcus (S.) strains from 29 organic dairy farms in Lower Saxony. The strains
were isolated from nasal mucosa and hand skin of milkers, herd bulk milk and mastitis
milk samples. After strain identification, the Oxacillin resistance was measured by Etest.
23 strains were identified as S. aureus, four as S. hyicus, 15 as S. xylosus and 31
as other coagulase negative staphylococci. Because of their minimum inhibition concentration
(mic) between 0.5 and 1 mg/mL four S. aureus isolates were assigned to
borderline Oxacillin resistant S. aureus. Nine coagulase negative isolates had this
property too. In total 19 staphylococci isolates had a mic > 1 mg/L and were classified
as Oxacillin resistant according to DIN 58940-4 Bbl 1:2004-02. Three of the resistant
four S. aureus strains were isolated from nasal mucosa and one from hand skin. To
confirm the results the Oxacillin resistance status need to be analysed in a greater
number of organic farms.
