Write a paragraph for when you once have Neisseria gonorrhoea bacteria in its pure form, what methods can you use to confirm the identity of this bacterium as N. gonorrhoeae? Mention what is the principle of those methods.

You have several different media onto which you inoculated eight strains of yeast (A-H). The media include a rich medium, an unsupplemented minimal medium, and minimal media each supplemented with one vitamin. Of the yeast strains, one is a prototroph and seven are auxotrophs for a vitamin. After overnight incubation, the following results were observed (tan patches represent growth): D plate 1 (A) B DE F GH plate 5 plate 4 plate 6 Which plate contains an unsupplemented minimal medium? [Select] Which plate contains a rich medium? [Select] plate 2 Which strain is a prototroph? [Select] Strain E is an auxotroph for niacin. Which plate reveals this specific auxotrophy? [ Select] plate 3 plate 7 One strain is an auxotroph for both choline and pantothenic acid. Which one is this most likely to be? [Select]

Can your draw it out and explain it to me please

Features of bacteria that aid _________ research aremonoploidy, which facilitates mutant identification,and rapid exponential growth, which allows recoveryof rare mutants.

You are given a mix culture of S. aureus,E. coli and P. aeruginosa. Besides the streak plate method what other methods could you use to separate the bacteria? Please state what method(s) you would use, the result you would be looking for to help identify each bacterium and the interpretation of the result.

What is the purpose of fixing a smear? Mark all that apply: 1. To attach the bacteria to the slide  2. To cause the cells to shrink and become distorted 3. To kill the bacteria so they aren't harmed by the staining method 4. To break down the cell wall in order to make the cells accept stain 5. To kill the bacteria to make the slide safer to handle

I need help answering this question to my professor:   The topic for the discussion was this one:   Some potentially pathogenic bacteria and fungi, including strains of Enterococcus, Staphylococcus, Candida, and Aspergillus, can survive for one to three months on a variety of materials found in hospitals, including scrub suits, lab coats, plastic aprons, and computer keyboards. What can hospital personnel do to reduce the spread of these pathogens?   My answer was this one:   To reduce the spread of these pathogens an infection control protocol should be followed. Some ways in which this could be reduced is by using desinfectants, sterilization, hand washing, and disposing techniques. In addition, I currently work as a dental assistant at Jackson Main and the protocol we use is hand washing our hands for at least 20 seconds before and after seeing every patient. We use CaviWipes to disinfect every surface and autoclave every single instrument after every use. Also, we make sure to…

What is the correct genus and species of your unknown Gram (+) bacterium?

You mixed up the numbers on the tubes when you inoculated the mannitol salt agar (MSA) plate. You do not know if you grew staph epidermis or E. coli. You found that the organism growing on the mannitol salt agar remained red after incubation. It is most likely that the organism is E.coli.  a) True b) False
