How much Agar do you need to grow bacteria on a Petri dish? How long does it take to culture Mycobacterium tuberculosis? What is doubling time in bacterial growth? How long does the lytic cycle usually take? Wha
coli cell can duplicate its DNA strand and split into two new cells in 20 minutes. Now, imagine that someone pours an antibiotic into the petri dish. Many antibiotics kill bacteria by gumming up one of the enzymes that the bacteria needs to live. For example, one common antibiotic gums ...
How long does it take to grow bacteria on a Petri dish with Agar? How long does leprosy last? How long does the rabies virus live in a dead animal? How long does adenovirus last on surfaces? How fast do bacteria become resistant to antibiotics?
Deadly outbreaks have plagued societies for centuries. But they can lead to medical breakthroughs—if we learn the right lessons from them.
in the laboratory, bacteria of the same species may need several days to double in especially harsh environments. Most pathogens grow rapidly, likeE. coli, but there are exceptions. For example,Mycobacterium tuberculosis, the causative agent of tuberculosis, has a generation time of between 15 and...

This is also the fate that awaits bacteria growing in a Petri dish, as you might remember from your high school biology course. Imagine a Petri dish with enough nutrients to support a growing bacteria culture until the dish is completely full of them. One bacterium is placed i...
In mycology, culture techniques are used to grow and study various characteristics of a fungus. Although it is relatively easy to culture fungi, a lot of care is required in such fields as medical mycology. This is due to the fact contamination can easily occur affecting the quality of ...
Tufenkji's group found that cranberry powder in a petri dish limited the growth of flagella and rendered the colony nearly motionless. Moreover, increased cranberry concentrations reduced the bacterium's production of an enzyme called urease, which contributes to the virulence, or severity, of infect...
There were two tubes used in this process: the tube that contained the primary culture and the tube that contained the nutrient agar where the unknown bacteria would grow. First, the inoculating loop was flamed. After removing the caps of both the test tubes, they were flamed to prevent cont...
