International audience | Udder infections were recorded in 3 herds throughout a lactation period with bacteriologic examination being done at 3-week intervals. New infection rates and levels of infection at calving differed significantly (P less than 0.001) between herds, but persistence of infection did not. Of the 324 infections, 80.5% lasted up to drying off. Of quarters infected with major pathogens, 16.8% eliminated their infection (63% became reinfected); 20.8% of quarters infected with minor pathogens eliminated their infection (43% became reinfected). Significant differences in persistence of infections, quarter clearing rate (defined as the rate at which infected quarters become and remain noninfected) and ability to give way to and to take place of a preexistent infection, did not occur between Corynebacterium bovis and major pathogens. Though 66% of coagulase-negative staphylococci infections persisted up to drying off, they disappeared more frequently (P less than 0.01).

International audience | The herd factor did not significantly affect distributions of somatic cell counts of 6,560 milk samples (collected in 3 herds) within an infection status. Minor-infections distribution for a herd was closer to that of healthy quarters than that of major infections. About 35% of the quarters infected by major pathogens had counts less than 400,000 cells/ml. Statistical analysis by conditional probability indicated that herd major-infection level should be taken into account to predict the probability of quarter infection by major pathogens. Discrimination with a good reliability between presence and absence of pathogens, as estimated by a single somatic cell count, is possible only in herds with high major-infection level.
