Probiotics (Nonpathogenic Bacteria) and Their Role in Infertility and Modulating Sperm Quality in Poultry

Probiotics are promising alternatives for the antibiotics used in poultry industry.Probiotics are live microorganisms and nonpathogenic that has a beneficial effect on the growth or physiology of the host when administered in adequate amounts.Infertility has become a common problem in recent decades in poultry industry.The pathogenesis of infertility is variable, but microbiological factors account for a large proportion of it.Pathogenic and nonpathogenic bacteria are ubiquitous and more specifically are naturally occurring in poultry semen. Pathogenic bacteria such as Salmonella, E. coli, Campylobacter, and Clostridium are all of concern when it comes to bird health. Pathogenic bacteria such as E. coli and Campylobacter spp. have a negative effect on mammalian sperm motility as well as rooster sperm. Pathogenic bacteria can cause harmful effects to birds. Nonpathogenic bacteria, Lactobacilli spp. and Bifidobacterium spp., are not known to cause harm to the bird when ingested as a feed supplement, but it has been reported that they may affect male fertility. Dysbiosis of vaginal microbiota is reportedly associated with female infertility, but the influence of normal vaginal microbiota on infertility is unclear. The purpose of this research noteis the physiological characteristics of the vaginal tract and vaginal microbial flora and vaginal Lactobacillus species. Also analyze the possible effects of administration of probiotics on vaginal microbiota and male and female fertility.
