Suppose you spilled two cultures of Salmonella typhimur-ium (each containing 100,000 cells) on your lab bench. You im-mediately applied the same disinfectant to both cultures at thesame time. One culture had been freshly grown for 36 hours andthe other culture is 2 weeks old. If the kill ing rate of the disin-fectant is 90% per minute, do you think that microbes in bothcultures will be completely killed after 6 minutes? Why or whynot?

What is one situation where Koch’s postulates are impossible to complete? In other words, what factors about a microbe or factors about a disease make it impossible for Koch's postulate to be performed with that microbe or disease?
select a microbe that has proven to be either environmentally or socially beneficial to human beings. You are not restricted to bacteria, but the organism chosen must be considered a microbe. In your post, include an explanation of the microbe's discovery, its use (either environmentally or socially), and its normal habitat. You should cite your research

In a campus-wide screen for microbes, you find DNA from the bacterial species that causes the bubonic plague, Yersinia pestis. You take the sample back to the lab, and try to grow (very carefully), but can't culture the organism. Provide two possible explanations for why you can't grow this sample in the lab.
