Fecal non-aureus Staphylococci are a potential cause of bovine intramammary infection

¹Cows were assigned an arbitrary upper case letter, independently of the other dendrograms.
²RAPD types were assigned an arbitrary lower case letter based on the clustering.
³Cow F (RF quarter) had 2 clinical mastitis cases with an interval of 32 days. Staphylococcus chromogenes RAPD type a was isolated from the first clinical mastitis case and S. chromogenes RAPD type b and d were isolated from the second clinical mastitis case.
^HQuarter milk samples with a SCC ≤ 50 000 cells/mL milk (healthy).
^SQuarter milk samples with a SCC > 50 000 cells/mL milk (subclinical mastitis).
^CQuarter milk samples from a quarter with clinical signs of mastitis (clinical mastitis).
