Epidemiological and microbiological characteristics of Streptococcus uberis as mastitis pathogen in Swiss dairy herds

Although Streptococcus uberis is a common cause of bovine mastitis, the epidemiology still is not fully understood and increasing rates of treatment failures are reported. To get a general idea about the situation in Switzerland 4 farms with S. uberis mastitis problems were examined by sampling all cows in lactation on two or three occasions. The microbiological analysis of the quarter foremilk samples were performed using standard procedures and a newly developed agar plate to identified S. uberis .
