Summary

603 ramdomized goats without clinical mastitis were studied to detect subclinical mastitis the month before dry period and after parturition. 1206 milk samples were analysed for bacteriology and somatic cell counts (SCC) were obtained using a Fossomatic counter.

Pathogens present in 17% of samples. Staphylococci was the more prevalent group of isolates (65%) and Corinebacteria was found in 27% of cases. We studied relationship between SCC and differents isolates to determine the pathogenic importance of each group.

SCC obtained before drying showed no statistically significant differences between infected and uninfected samples. They are statistically significatives differences (p<0,05) between CSS of samples infected with Staphylococci (μ=l.466.000 sc/ml) and bacteriological negative samples (μ= 1.119.000 sc/ml), but there are not differences between SCC of samples infected with Corinebacteria and bacteriological negative samples.

At the beginning of lactation, there are statistically significant differences (p<0,001) between infected samples (μ= 2.186.000 sc/ml) and uninfected (μ=1.235.000 sc/ml). There are statistically significant differences (p<0,001) between CSS of samples infected with Staphylococci (μ=2.248.000 sc/ml) and bacteriological negative samples, and they are not differences between SCC of samples infected with Corinebacteria and bacteriological negative samples.
