Afternoon all, could do with a nudge in the right direction with my biology report on microorganisms.
Basically, what could cocci (round) gram negative bacteria be?
We left a petri dish containing agar out in our classroom and then left it in the fridge for one week.
After gram staining and viewing with an oil immersion lens, one of my samples had hundres of cocci, gram positive bacteria - but there were also about 5 cocci, gram NEGATIVE bacteria in the section I was viewing. I cannot find out what these could be and would like to find out some possibilites to put in my report.
Can anyone gimme an idea, please? I have tried to find out myself, but can only find bacilli gram negative.
Thank yous, would really appreciate some help x
