title: [Investigations on the behavior of C-reactive protein, cell count, lactose content as well as electric conductivity in quarter milk samples of subclinically diseased quarters of the udders in relation to bacteriologic results].
abstract: Inflammations of the udder influence the amount of somatic cells and lactose as well as electrical conductivity in milk. They are often caused by bacterial agents. Similar reactions are to be seen in relation to C-reactive protein (CRP). The amount of CRP in milk depends on concentration and characteristics of the agents and the phase of inflammation. We found a significant increase of CRP in milk samples with Streptococcus (Sc.) uberis. There was no significant difference in CRP concentrations in samples with coagulase positive Staphylococcus spp. (CPS) and bacteriological negative samples and such with Corynebacterium (C.) bovis, Micrococcus spp. and Staphylococcus (S.) epidermidis. We only found high correlations to the amount of somatic sells and lactose as well as electrical conductivity in samples with Sc. uberis. The results of our investigations show that CRP may be a parameter for better understanding subclinical inflammations of udder.
