Did each handwashing treatment result in similar types of organisms growing on the plates? (look at the colonies and gram types) Explain why or why not?

Why is nigrosin-water- bacteria puddle need to be mixed in a Simple/Negative staining

For the picture below, answer the following questions: A. What is the shape of the bacteria? B. What is the arrangement of the bacteria? C. If this slide shows a Gram stain, what is the Gram stain reaction? If this slide does not show a Gram stain, please state that as your answer. ASM MicrobeLibrary.org Smith

You perform several tests on an unidentified bacterial species and get the results below. Based on the test results and the bacterial table, you narrow down the identity to two possible bacteria. Which test should you now do with these bacteria to narrow down the possibilities to just one bacterial species from the bacterial table? (In other words: knowing the results from which test would let you identify these bacteria?) Gram reaction result: Citrate Test (Tube B): O Nitrate reduction test Motility test MSA plate O Glucose fermentation test E
