==Elimination of Bacterial Contamination of the Reproductive Tract==
 +
Generally, parturition in domestic animals occurs in a non-sterile environment.  As a result, bacterial contamination of the reproductive tract, especially the [[Uterus - Anatomy & Physiology|uterus]], is an inevitable sequela to parturition.
 +
 +
* The postpartum tract containing lochia is an ideal environment for the growth of bacteria.
 +
* Even though myometrial contractions remove the large volume of lochia, bacterial growth can continue.
 +
* Bacterial contamination is not always associated with pathology.
 +
* Normal post-partum events eliminate the bacterial flora within a reasonable time.
 +
* Elevated oestrodiol promotes leukosis in the uterus and elsewhere in the tract.
 +
 +
 +
* In some cases, high numbers of bacteria can overwhelm the natural defence mechanisms, resulting in [[Healing and Repair - Pathology#Female|postpartum uterine infection]].
 +
* Conditions that predispose the uterus to infection are:
 +
** Retained foetal membranes
 +
** [[Dystocia]]
 +
** Delay in lochial expulsion due to weak myometrial contractions.
