While manly affecting people with compromised immune systems the bacteria is usually always found in hospitals and is spread through physical contact. While its natural habitat has yet to be discovered, A.B is known to cause illnesses such as Pneumonia and Meningitis. Overtime A.B has developed a strong antibiotic resistance, while being able to survive in harsh conditions for extended periods of time. These traits make this deadly bacteria very tough to eradicate in patients.

Biologically, it is a rod-shaped, flagellate, facultative aerobic, Gram-negative bacterium and a species of the genus Salmonella. It is typically found in the intestinal tracts of animals and usually transferred to Homosapiens when they eat animal products contaminated with feces. The bacteria has allegedly caused illness for over 125 years and was discovered by American Scientist, Dr. Salmon. 
     Within 72 hours, those infected with Salmonella commonly experience diarrhea, fever, and abdominal cramps. While many recover without treatment, symptoms may become so grave that one may have to be hospitalized. I these severe cases, salmonella may spread to the bloodstream and result in fatality if not treated with antibiotics.

Salmonella are gram-negative, rod-shaped bacilli that can cause salmonellosis, a diarrheal illness in humans. Typhoid fever, food poisoning, gastroenteritis, enteric fever, and other illnesses are all types of Salmonella infection. There are over 2,300 subtypes of the Salmonella enterica bacterium.

It is a rod-shaped, Gram-negative soil bacterium. Symptoms are caused by the insertion of a small segment of DNA (known as the T-DNA, for 'transfer DNA', not to be confused with tRNA that transfers amino acids during protein synthesis, confusingly also called transfer RNA), from a plasmid, into the plant cells, which is incorporated at a semi-random location into the plant genome.

MRSA can be found when S. Aureus overly develops to form this often harmful bacteria. MRSA has the “super”  in its name because it is resistant to antibiotics such as methicillin, (hence “methicillin resistant”) and penicillin. However, most cases of MRSA infections and diseases can be treated by some type of antibiotic.

It is a gram-negative, lactose-fermenting, non-motile, encapsulated, faculative anaerobic, rod-shaped bacterium. It appears as a mucoid lactose fermenter on MacConkey Agar. Although it is found ubiquitously on the mouth, skin and intestines, it can cause significant damage only when inhaled, specifically in the lungs, resulting in a bloody sputum. Some strains are incredibly resistant to many antibiotics because of their plasmids, and so they can be very difficult to treat, especially with the weakened immune system of the individual being the primary cause of infection.]]> 2018-10-24 22:37:57 UTC https://padlet.com/dlerman/prokaryotes/wish/296709785 https://padlet.com/dlerman/prokaryotes/wish/296710770 Clostridium Botulinum is a Gram-positive, rod shaped, anaerobic bacterium that produces the neurotoxin botulinum.
