[Cell content and bacteriological findings in individual cow's milk samples].

Hundred thirty seven milk samples were investigated by the mastitis test "Sofia" after the "Breed" method for the assessment of cell content and by inoculation on 5% blood agar for bacteriological findings. A certain correlation between reaction degree and number of cell elements was established. The better expressed the test reaction the larger was the number of cell elements, but not always a full coverage was evident. A correlation existed between the number of cell elements and the bacteriological findings also. The stronger the reaction resp. the larger the number of cells, the more samples had positive bacteriological findings. The percentage of samples with positive bacteriological findings having a cell number of 500 thousand to 5 million cells per 1 cm3 of milk ranged within 70.83 to 96.30%, while for samples having a cell content above 5 million it was 100%. In the samples with positive reaction the bacteriological investigations established 38.48% staphylococci, 52.28% streptococci, and 10.74% various other microorganisms.
