- Why is a block of agar inoculated rather than streaking the fungal culture on a plate?If you notice on your agar plate that there are more than one color of colonies-- What does this mean? What should you do? Can you use this plate for the identification of an unknown bateria?Gardnerella vaginalis is a gram variable rod. What type of media should be used when culturing for it? Describe the appearance of the colonies.
- Why is it important to use a sterilized loop between streaks when preparing a streakplate? Observation of a streakplate culture shows more growth in Quadrant 4 than in Quadrant 3. Account for this observation. Describe the way in which you can isolate an individual colony from a spreadplate or a streakplate that holds multiple colonies. Outline the differences between a streak plate and a spread plate.what is the form, elevation, margin and colony color of this streak plate result?What is the laboratory's policy in decontaminating the plates? Since the growth of H. pylori was accidentally discovered, what can you conclude about it?
- Why is staining of stool samples very important in identifying parasites?1) would you describe the contents of the soil-inoculated broth as being a “pure culture”? Why or why not? 2) How did the uninoculated broth differ in appearance from the broths inoculated with E. Coli and M. Luteus? And then how could you tell if a supposedly sterile, uninoculated broth was contaminated? Please explain in detail and highlight the important parts cuz I am confused and need help! ThanksAfter the original specimen has been plated and a reported gram-negative rod was seen on the initial gram stain, what is your initial assumption of the organism causing this disease?
- how could you determine if there is any contamination on your agar?During the preparation of a smear leading into simple staining of the bacterial culture S. epidermidis you forgot to heat fix the slide. What would you see on this slide as compared to a slide that was properly prepared? Please explain.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
