Abstract:		"The vaginal microbiota has been studied in animal reproduction and fertility, in particular little information of vaginal microbes in reference to bovine reproduction and pheromone production is known. The vaginal mucosa in healthy cow is colonized by an equilibrated and dynamic composition of aerobic, facultative anaerobic and obligate anaerobic microbes. Cervico-vaginal mucus (CVM) composition, viscosity and volume vary with the cyclicity and health status of the reproductive tract. In addition, CVM contains pheromones, volatile compounds, and proteins that attract males for coitus. Commensal microbiota plays a key role in protection of the genital tract from pathogenic microbes by competition effect. In the bovine species, the microbial composition, its abundance and diversity in the female gut, vagina, urine, saliva, and feces, and the associated chemical communication remains poorly documented. The impact of microbes in the reproductive tract of cow, buffalo and certain mammals are discussed in this review. Since the microbial population diversity of CVM is modified during estrus phase it presumes that it may have a role for pheromone production in conspecific. Herein, we would like to critically discuss the current state of knowledge on microbially produced signals in animals and the role of genital and CVM microbiota in estrous cycle and pregnancy"
