I did a gram stain and I can't figure out the arrangement of my unknown bacteria. I see a lot of diplococci, but I'm getting confused because I see 1 or 2 streptococci and a couple of staphylococci and several single cocci as well. Why are there so many different types of arrangement in my specimen? It's supposed to only be one type of bacteria, and yet there's so many different arrangements.
Been a long time since I did a gram stain, but I remember them being very prone to contamination. You sure this is not the case in this instance?
first you have identify the bacteria with gram stain kit
if color is blue its means Positive bacteria and if color is Red then its means negative bacteria in which other tissues are remain yellow
