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?
Step by step
Solved in 2 steps
- What culture medium can be used for the acclimatization of Bacillus and Pseudimonas to degrade phenol? It must be a nutrient-poor growing medium.Why is a block of agar inoculated rather than streaking the fungal culture on a plate?Why are the streak plates incubated at 7°C when selecting for psychrotrophic bacteria?
- How can you use the unique characteristics to produce a growth medium that is both selective and differential that can aid in the isolation of Listeria monocytogenes?how does increasing the incubation temperature at which a plate containing psychrotrophic bacteria might influence the quantitative dilution and plating of the smaple?• Which bacterium produced a yellow halo, and how do you interpret this result? • If you grew Staphylococcus epidermidis on MSA, what result would you expect?
- How do you isolate cryptosporidium from sewages and the best technique used?What is the main advantage of using the slide culture technique for identifying molds?what is the physical characteristics of this streak plate? Look at a single colony on a streak plate and look for special physical characteristics such as: motility, possible presence of endospores and/or capsule, culture color?
- Is staphylococcus a parasite or saprophyte?Gardnerella vaginalis is a gram variable rod. What type of media should be used when culturing for it? Describe the appearance of the colonies.What was the purpose of leaving the cover on one set of agar plates? How did the growth on these plates differ from the growth on the uncovered plates that were exposed to UV light for the same amount of time?
