Description:This image depicts a Petri dish culture plate that had been stocked with Thayer-Martin medium, and inoculated with Neisseria gonorrhoeae bacteria. The bacterial organisms grew umbilicated,, i.e., concave in their center, colonies, which is an atypical morphologic characteristic for N. gonorrhoeae colonies. However, when these organisms were subcultured, which means regrown in another Petri dish, the organisms grew colonies of normal morphology.
Typically, N. gonorrhoeae organisms grows small, grayish white, convex (not concave or umbilicated), translucent, shiny colonies with either smooth or irregular margins. The atypical results of this test were of unknown significance.
