Resumen:
The aim of this work was ®rst, to determine the predominant groups capable
of colonizing the vagina and maintaining high numbers with time. The normal microbial
¯ora of the cow's vagina and its evolution from weaning to service was then studied using
standard microbiological methods. The results show that the most dominant bacteria belong
to the streptococci, followed by the staphylococci, with similar levels during the whole
study period. Enterobacteriaceae and lactobacilli were present at very low levels, the latter
increasing during the cow's growth, suggesting some kind of hormonal in¯uence. The
results will allow the selection of micro-organisms with probiotic characteristics, classified as
GRAS (Generally Regarded as Safe), to be used in the prevention of infections in the
vaginal tract of cows, such as metritis, which produces delayed periods between partum and
conception, and consequent economic losses.
