− | The normally '''sterile''' uterus is '''contaminated by environmental microorganisms during parturition''' or '''immediately postpartum'''. The main bacteria involved in endometritis is '''''Actinobacillus pyogenes''''', however, numerous [[:Category:Gram Negative Anaerobic Bacteria|'''gram-negative anaerobes''']] may also be involved. The presence of this opportunist bacteria can '''delay return to service''' and '''cyclical activity''', '''prevent fertilisation''' and cause '''early embryonic death''' by producing a hostile uterine environment. It is also reported that it increases incidence of '''ovarian cysts'''. | + | The normally '''sterile''' uterus is '''contaminated by environmental microorganisms during parturition''' or '''immediately postpartum'''.
