Question

100%

If some cells in your Gram stain are red/pink rods and some are purple cocci, __________.

your smear was not made from a pure culture

your unknown bacterium is a pleomorphic species

the bacteria ferment sucrose

your unknown is a species of Escherichia

you should inoculate an EMB agar plate

Definition Definition Technique that uses crystal violet or methylene blue as primary staining colors to distinguish gram-positive from gram-negative organisms. Under a microscope, the gram-positive organisms appear purple-brown, retaining the primary color. Gram-negative organisms appear pink or red as they do not acquire the color of the primary stain.

I'm having trouble identifying the type of bacteria I have cultured. I know that it is gram-negative and cocci in shape, it grows wonderfully on the MSA plate but did not grow so well on the EMB plate, and it is non-motile. It has a yellow color but I'm just not sure what it is. It was obtained from a public area. Any ideas?
