Antibodies Against Staphylococcus Aureus Nuclease in Bulk Milk As An Indicator of Mastitis in Dairy Herds
Antistoffer mot Staphylococcus aureus-nuklease i leverandørmelk som indikator på mastitt i storfebesetninger.
Acta Veterinaria Scandinavica volume 21, pages 96–107 (1980)
Abstract
Titres of staphylococcal antinucleases and cell counts in bulk milk samples were compared as indicative criteria of the mastitis situation in dairy herds. The correlation coefficients between the prevalence rate of mastitis and the antinuclease titre and cell count, respectively, were of the same order of magnitude. The incidence of clinical mastitis showed a better correlation to the antinuclease titre than to the cell count. When cell counts and antinuclease titres were combined a more reliable selection of herds with a possible mastitis problem was achieved. The antinuclease test is consequently recommended as a supplement to cell counting when screening bulk milk.
Sammendrag
Titeret av antistoffer mot Staphylococcus aureus-nuklease og innholdet av celler i leverandørmelkprøver er sammenlignet som kriterier for mastitt i storfebesetninger. Korrelasjonskoeffisienten mellom forekomsten av mastitt og henholdsvis antinukleasetiteret og celletallet var av samme størrelsesorden. Frekvensen av klinisk mastitt var bedre korrelert til antinukleasetiteret enn til celleinnholdet.
Ved å kombinere celletallet og antinukleasetiteret oppnås en mer pålitelig utvelgelse av besetninger med et mulig mastittproblem, og antinukleasetesten er derfor anbefalt som et tillegg til celletelling av leveråndørmelk.
