Enterobacter+aerogenes+number+4

//__**Enterobacter aerogenes**__// //Alexa Rakusin Muna.//

The shape of E. aerogenes is rod-shaped (bacillus) yet short and almost rounded or spherical (coccus).
 * Shape** -

E. aerogenes grows best at 30 degrees Celsius, or about 86 degrees Fahrenheit.
 * Temperature** - //30 degrees Celsius//

This means that the E. aerogenes have a two-layer cell wall, composed of lipids and carbohydrates. The gram stain turned the bacteria pink, indicating that the crystal purple couldn't penetrate the second outer layer, while the Safranin could.Gram Negative Stain
 * Gram** **Stain** - //Gram negative stain//

The E. aerogenes tested Methyl Red Negative, because after being incubated in glucose broth and being added with methyl red, the substance turned bright orange. This indicated that when the bacteria digests glucose, it produces a neutral waste
 * Methyl Red** - //Negative//

The E. aerogenes tested to be motile. This was discovered using a procedure, where the bacteria culture was stabbed into a tube of motility test agar on the tip of an inoculating needle. We determined whether they were motile or not based on whether the bacteria spread from the stab-line, or whether it only grew within the stab-line.
 * Motility** - //Positive//

The E. aerogenes tested to have Gamma hemolysis. This means that the bacteria doesn't digest Hemoglobin.
 * Hemolysis** - //Gamma//

E. aerogenes

E. aerogenes is facultative, meaning that it is both aerobic and anaerobic (it can thrive in oxygenated environments and deoxygenated environments). This was tested by placing a sample of the bacteria in a glass jar. Then a candle was burned inside the jar, ridding it of the oxygen. Other sample were left outside of the jar, where oxygen was available. Observations were made to determine whether it was or was not aerobic.
 * Aerobic** - //Facultative//

With a Bauer-Kirby test, we discovered that out of Tetracycline, Penicillin, Streptomycin, and hand santizer, Tertracycline is the most effective at killing E. aerogenes. The Tetracycline had the largest zone of inhibition, 15 mm in diameter, while Streptomycin came in second, with a 10mm ZOI in diameter. The Penicillin and hand sanitizer both had a 0mm ZOl. Tetracycline was the most effective because this antibiotic is often used to cure infections in the genital or urinary tract, and E. aerogenes is a gastrointestinal tract infection. Streptomycin is a general bactericidal antibiotic, so that is why it did work on the E. aerogenes, but not as well as the Tetracycline. Penicillin was not very effective in killing the bacteria, because it typically works best on Gram positive bacteria, and E. aerogenes is Gram negative. Hand sanitizer was not very effective either, because often hand sanitizers are antiseptics, used for the prevention of pathogens, instead of previous infection.
 * Antibiotic Testing** - //Tetracycline//

Enterobacter aerogenes is most often found in the gastrointestinal tract of the human. This bacteria does not actively infect until prompted by environment causes, such as: various antibiotics,venous catheter insertions, or surgical procedures. Some places in the gastrointestinal tract that could inhibit infectious Enterobacter aerogenes could include: stomach, small intestine, colon, cecum, apendix, rectum, or anus. Other places this bacteria has been found were: different waste products, hygene chemicals, and soil.
 * Environment** - //Human Gastrointestinal Tract//

E. aerogenes does not typically infect people with healthy immune systems. It is pathogenetic and nosocomial (caused by treatment in hospital). Most of the bacteria infections are due to careless transfers of bacteria from surgery or consistant treatment in hospitals for patients who use venous or urethral catheters. E. aerogenes is often drug-resistant, and cannot be cured with drugs. Antiseptic surgery and watchful waiting is often necessary to cure. Septic shock and organ dysfunctions can be symptoms of an E. aerogenes infection. Enterobacter aerogenes, Gram Negative Stain [] [] []
