All of body membranes have a micro flora and these bacterial micro floras have a serious role to prevention of others bacterial attack and occasionally they can invade to damaged membrane and they can make an infection. Vaginal micro flora is importance because these bacteria can able to migrate to other part of urogenital system. Many organisms find in the vagina and these organisms can not invade to intact membranes. Some of these organisms are pathogen but many of them are saprophyte.

In a young female dog that presented to Tabriz Islamic AZAD university pet clinic, after routine examination, the owner want to check estrus cycle. In the vaginal examination, there is no evidence of infection but membrane seems congested with no evidence of estrus. Vaginal cytology shown diestrus but we take a microbiologic specimen for routine culture. Specimen was send to laboratory by transport media and cultured in MacConkey agar, Blood agar, OF and oxidase and catalase test Media. Many organism isolated from this specimen. Moraxiella isolated from specimen. The female dogs not a clinical vaginitis but we treated with amoxicillin and gentamycin for ten days.

Because of natural position of vagina in the female dogs, many bacteria may be seen in the vaginal membrane and so that contamination of vulva or vagina with fecal or skin micro flora may be occurring. In all texts, E.coli is a commonest bacterium that isolate from vagina. This matter was shown contamination of vagina with fecal micro flora but isolation of moraxiella is a rare condition.
