An aerotolerant anaerobe is a microbe which will survive but will not grow in the presence of oxygen.…
Bacteria: These are tiny microorganisms, they cannot be seen with the naked eye. They exist on virtually every living thing or object in the environment i.e. dirt, water, caves, trees, dead animals, and within everybody living on earth. Its nutrition is from its surroundings. We carry bacteria in the body, mainly in the intestines, on the genitalia or on the skin. Bacteria can be good or bad. It can help our immune system but there are bad bacteria which make you become ill. Meningitis is a bacterial infection, this can be life threating to a young baby and is most common in young children. It is an infection of the membranes covering the brain and/or spinal cord, this is a reason it can be life-threatening. MRSA is another big bacteria illness, this commonly affect hospitals and is due to lack of hygiene. Food poisoning is a common cause of illness caused by bacteria. This is because bacteria lives on food. If cooked and food has not reached a high enough temperature to kill off bacteria then it can cause the bacteria to rapidly grow and cause sickness to a person. The types of food poisoning are; salmonella, E. coli, norovirus, campylobacter, listeria, clostridium perfringens. These are also linked with viruses too. Also most sexual transmitted diseases are a bacterial infection i.e. syphilis, gonorrhea. Also Lyme disease, this is spread by the bite of a deer ticks most common around wooded, rural areas. If untreated it causes an arthritis-like condition that can last for months.…
We identified that K. pneumoniae is a facultative anaerobe. When inoculated onto an agar slant, K. pneumoniae took the shape of echinulate. When inoculated onto a nutrient agar plate, we identified that the growth of K. pneumoniae was round and smooth with a convex elevation.…
E.coli was found facultative anaerobe because the growth was seen throughout the middle but was not near the…

It is useless for living specimens of bacteria, and inferior for non-photosynthetic protists or metazoans, or unstained cell suspensions or tissue sections. Here is a not-so-complete list of specimens that might be observed using bright-field microscopy, and appropriate magnifications (preferred final magnifications are emphasized). Prepared slides, stained - bacteria (1000x), thick tissue sections (100x, 400x), thin sections with condensed chromosomes or specially stained organelles (1000x), large protists (100x). Smears, stained - blood (400x, 1000x), living preparations (wet mounts, unstained) - pond water (40x, 100x, 400x), living protists (40x, 100x, 400x occasionally), algae and other microscopic plant material (40x, 100x,…
Viruses. These micro-organisms are very tiny. They invade living normal cells and use these cells to multiply and produce other viruses like themselves. Eventually this kills off the normal cell and can make you ill.…

Amebicides work by killing off all the bacteria that act as nutrition for amoeba, leading to its indirect destruction.…
Sixteen-year old Sebastian DeLeon is the fourth person in 50 years to recover from a brain-eating amoeba. According to the ABC News article, published on August 23rd, 2016, Naegleria fowleri inhabits fresh water lakes and ponds. The amoeba travels up the nasal passage infecting the brain tissue and causing death in 97% cases. DeLeon was transported to the hospital after suffering from severe headaches and experiencing signs of early meningitis. After conducting spinal fluid tests, doctors were able to identify the amoeba and treat DeLeon with miletfosine, a medication shown to have promising results in eradicating Naegleria fowleri. After several days in an induced coma, DeLeon is now on his way to a full recovery.…
Although the unknown tested positive for growth in 7.5% NaCl, it grows fine without it. This narrows any following tests to be performed to those that would differentiate between Genus Micrococcus and Genus Deinococcus. The following is a list of species to be considered among Deinococcus and Micrococcus, collectively:…

For how wide spread of a sampling of bacteria we obtained, the actual colony observations didn't differ drastically. All samples, including the control, were in and around the same color spectrum in lightish brown coloring. The control, stair railing and neath of the fingernail were all circular in form and the margin for those three was also entire and all elevations were convex. The diameter of the actual colonies was where the most diverse observations occurred. The percentage varied from one to fifty percent and the millimetre size also varied from less than 2mm to about 5mm.…
Colonies of S. warneri are usually tan, yellow and about 2-4mm in diameter after 48…
