It is recommended that you schedule your work as follows: Gram stain your broth and streak it out onto the following media: TSA -- general purpose medium 2.
Enterobacter Aerogenes Enterobacter aerogenes, part of the Enterobacteriaceae Family, is a rod-shaped bacteria that causes bacterial infections, and is usually acquired in a hospital or hospital-type atmospheres.
It usually causes opportunistic infections, meaning that it will usually only cause a disease in a person or host that has a compromised immune system.
Studies are now showing it causing increased alarm in community infections. It rarely is known to cause a disease in someone with a healthy immune system. Even though they can be extremely sensitive to antibiotics, these bacteria easily become unaffected by typical antibiotics due to their significant ability to become resistant through their adaptive capabilities.
It is Gram-negative and anaerobic. They are seen throughout nature, including fresh water, sewage plants, and vegetables.
Although it normally prefers and multiplies quickly in places with a small amount or no oxygen, it can grow and live in oxygen-abundant areas.
It is related to Enterobacter Coli and Salmonella. Its preferred temperature for growth is 37 degrees Celsius. In laboratories, it also grows quite quickly in milk nutrients, salts, and dyes.
Surgical procedures, intravenous catheter insertions, and some antibiotic treatments are ways that result in the infection of Enterobacter aerogenes.
The unknown gram-positive bacterium was confimed as being Bacillus cereus, and the gram-negative being Enterobacter aerogenes. Enterobacter aerogenes is commonly seen as being the cause of lower respiratory tract infections, skin and soft-tissue infections, urinary tract infections (UTIs), endocarditis, intra-abdominal infections, septic. Identification of Unknown Bacteria Identify unknown bacteria. Review microbiology core technical competencies. Introduction Identification of unknown bacteria will allow the student to review. ð•come to lab prepared to run tests Hand in a report of the testing performed (U nknown identification sheet), a journal of how Gram stain your unknown organism using the TSB broth culture. Note the shape, arrangement and Gram reaction of your organism. 7.
The gastrointestinal tract is usually where it is found in a human, and it is known to cause respiratory, urinary tract infections, osteomyelitis, and septic arthritis. They also cause burn, wound, and bloodstream infections. It has also been shown to cause meningitis and central nervous system infections.In order to identify which Gram negative bacteria was present, Klebsiella pneumonia or Enterobacter aerogenes, it was decided to perform Urea test, that finally confirmed that gram negative unknown was Enterobacter aerogenes.

Apr 29, · The unknown bacteria will be one of the following: Enterococcus faecalis, Staphylococcus saprophyticus, Escherichia coli, Enterobacter aerogenes, Proteus vulgaris, Salmonella [I assume typhimurium], or Shigella [either flexneri or sonnei, we used both in our lab .
Unknown Lab Report: Enterobacter cloacae Jessica Sainvil Professor Cupido Bio L1 Thu Due Date: 12/6/12 Unknown# Introduction The bacterium Enterobacter cloacae isolated from the given # was a Gram-negative Rod.
The purpose of this lab was to isolate and identify the genus and species of an unknown bacterium.
Unknown A had a positive result meaning that is was able to use citrate as a sole source of carbon, confirming that the Unknown A was Enterobacter aerogenes. Enterobacter aerogenes (E. aerogenes) is in the Enterobacteriaceae family (2).
