Backdrop of the Study

Placenta is definitely an appendage characteristic of any true mammal during pregnancy, getting started with mother and offspring, offering endocrine release and selective exchange of soluble, but not particulate, blood vessels borne substances through an opposition of uterine and trophoblastic vascularized parts. Although many bacteria may cause the problem of the parias, the most common patient associated with this kind of septicity contains Staphylococcus aureus, Escherichia coli and Bacteroides.

Staphylococcus aureus and Escherichia coli can easily grow over a wide range of multimedia. Primary seclusion can be produced on a Nutrient Agar, Apple pc Conkey Agar agar or Bloodstream Agar Plate.

On Chemical Agar, Staphylococcus aureus generates round, convex, well identified colonies, and measuring 2-4 mm in diameter. The colonies show a buttery consistency using a smooth glistening surface. Staphylococcus aureus makes golden yellow colonies as a result of production of staphyloxanthin. In respect to Burgess et approach, of the Walt and Eliza Hali Start of Medical Research: " Human placental conditioned moderate is able to stimulate human bone fragments marrow cellular material to form neutrophilic granulocyte-monocyte colonies and eosinophil colonies in agar cultures. ”

The question in everybody's mind is definitely: Is it possible to expand a gram negative and a gram positive bacterias on an agar supplemented by simply Placenta.


I. Organizing the Placenta

a. Boiling of Parias (25g, 50g, 100g) in a 500 cubic centimeters distilled drinking water b. Pressure to get the broth

II. Prep of Placental Agar

c. Mix the broth from a 25 g placenta to 1 tsp of agar powder. Do the same for the broth with 50 g and 75 g placenta respectively deb....
