On this week I went ahead and streaked a Hektoen Enteric agar plate with a colony from the isolation plate of Salmonella enterica just to make sure that this plate in fact had ONLY Salmonella growing on it, since the colony growth on it was unfamiliar. The HE plate is a selective and differential agar primarily used to identify Salmonella from an unknown culture.To my surprise, the HE plate showed positive results, meaning that this colony is Salmonella. However, the results also indicated that this microbe didn't show indications of lactose fermentation or hydrogen sulfide production; so it remained its original green color.
I then went ahead and made Gram stains for B. subtilis, S. aureus, E. faecalis to take a look at the cell morphology of them. Unfortunately, I smeared too much bacteria for B. subtilis so could not really see much of the cell shape due to how much clumps were present on the slide.
I hope you figured out what the shape of your bacteria was, because we don't want a miss lead again, lol. The stains look really good though, mine didn’t even turn out like that when I did it, probably cause I did a really crappy job on doing the stain properly.
