| Abstract: | "Mammals have microbes resident in their reproductive tract, some of which can be pathogenic while others may play a role in protecting the tract from infection. Volatile compounds play a role as sex pheromones that attract males for coitus during female estrus or heat. It is likely that these compounds themselves are secondary metabolites of bacterial flora resident in the vagina. In order to substantiate this hypothesis, bacteria were isolated from cervico-vaginal mucus (CVM) of buffalo during various phases of the estrous cycle and identified, using morphological, biochemical and molecular characteristics, as Bacillus during preestrus and diestrus, and as Staphylococcus during all three phases of the estrous cycle. Populations of Staphylococcus differed between different phases of the estrous cycle, the predominant forms being S. warneri (BCVMPE1_1) during preestrus, S. pastueri (BCVME2) during estrus and S. epidermis (BCVMDE3) during diestrus. Mice were used as chemosensors to differentiate the estrus-specific S. pasteuri (BCVME2) from the others. Chemical analysis showed that S. pasteuri (BCVME2) produced acetic, propanoic, isobutyric, butyric, isovaleric and valeric acids. In addition, it was shown that S. pasteuri (BCVME2) volatiles influenced the sexual behaviors, flehmen and mounting, of the bull. Thus, S. pasteuri (BCVME2) is a potential source of vaginal pheromone(s) during estrus in buffalo" |
