In the study 224 lactating cows in their middle lactation, producing milk with a somatic cell count (SCC) less than 400 000/ml were involved. Quarter and individual composite milk samples were subjected, respecitvely to California Mastitis Test (CMT) and somatic cell counting (Fossomatic method). 41 udder quarters of 34 cows showed a positive CMT reaction greater then "+", which means 15,18% of the total cows. In the SCC groups <100 000/ml and 100 000-400 000/ml respectively 7,63% and 23,58% of the cows had at least one inflammed quarter. The authors propose that all of the lactating cows should be involved in the screening tests of the infected udder quarters.
