How long is the parvovirus contagious in humans? Is leishmaniasis found in the blood? How long does it take to grow bacteria on a Petri dish with Agar? How long can an amoeba survive in a completely dry environment inside a cyst?
Sterilize any tools that come into contact with the mushrooms, mushroom spoor or potting soil. Bacteria that can form on the tools can kill morel mushrooms. One of the best methods to sterilize the tools is to heat them over an open flame....
Bacteria require a warm, moist environment between 70 to 95 degrees Fahrenheit for optimal growth. An enclosed environment that minimizes temperature fluctuation and exposure to the external environment is also important. A glass aquarium provides a satisfactory container to use as an incubator. Since ...
The slimy coating on unbrushed teeth is biofilm, and the beneficial microbes on your skin and gut often grow collectively. They were killing each other like crazy. —Bonnie Bassler, Princeton University Biofilms form when groups of bacteria cover themselves in a sticky mixture of sugars, ...
Over the course of many millions of years, the processes of mutation and natural selection have created every species of life that we see in the world today, from the simplest bacteria to humans and everything in between. Billions of years ago, according to the theory of evolution, chemi...
The bacteria are classified as microaerobic bacteria. But like Mucoccus mutans and Flexorbacter columnaris, it must exist in oxygen to grow and reproduce. This kind of bacteria can be classified as aerobic bacteria, so it is impossible to find Flexorbacter columnaris in the intestine. Infection ...
(grow them in a nutrient-rich solution) in a Petri dish in the laboratory. The stem cells divide several times and scientists divide the population into other dishes. After several months, there are millions of stem cells. If the cells continue to grow without differentiating, then the ...
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 ...
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...
