Summary. Coagulase-negative staphylococci are a
frequent cause of bovine intramammary infections in
modern dairy herds. They have become the most common bacteria isolated from
milk samples in many countries. Because of high prevalence of these intramammary infections it has a
great impact on bulk tank somatic cell count. The objective of the study was to
analyze the impact of coagulase-negative
staphylococci intramammary infection on cows somatic
cell count and on the potential of these infections to have a major impact on
the bulk milk somatic cell count. The study was conducted
on two dairy farms with high milk production and increased number of somatic
cells in bulk tank milk. Bacteriological examination of milk samples from cows
positive on CMT test pointed high prevalence of coagulase-negative staphylococci in cows with secretion
disorder in both herds, up to 81.8%. Somatic cell count in these milk samples
was also very high and counted over 1 million per milliliter. The highest
number of somatic cells was in milk samples from cows with Staphylococcus
aureus, but prevalence of these infections was very low.
Keywords: coagulase-negative staphylococci, intramammary
infection, somatic cells
