===Significance===
<p><i>P. aeruginosa<i> is considered one of the most common gram-negative infections in hospital settings, especially in settings consisting of weaker immune systems.

This bacteria can be found in water, which can lead to eye and ear infections by direct contact with this microorganism. It can also cause mild illnesses and rashes in both children and adults. Therefore, it is essential to maintain clean environments for patients and healthcare providers because <i>P. aeruginosa<i> can easily spread from patient to patient [3]. These infections are generally treatable with antibiotics, but are becoming more difficult to treat overtime due to antibiotic resistance.</p>

Description and Significance

  • Interesting features of cell structure; how it gains energy; what important molecules it produces.

Cell Structure, Metabolism, and Life Cycle

Pseudomonas aeruginosa is a Gram-negative and bacillus (rod-shaped) bacterium. Gram-negative indicates that it has an inner layer of peptidoglycan in its cell wall, as well as an outer layer of lipoprotein and lipopolysaccharides. Its colonial color is brown or metallic sheen, with a blue-green extracellular pigment.

P. Aeruginosa Master Plate

Its colonial morphology is small, entire, convex, and mucoid. P. aeruginosa has a blue-green appearance when cultured, which stems from the latin word "aeruginosa" meaning "copper rust". However, from our culture of patch number 5, this microorganism appeared cloudy white.

P. aeruginosa is a facultative anaerobe, which indicates that it can produce ATP by aerobic respiration in the presence of oxygen or by anaerobic respiration in absence of oxygen.

This microorganism has a tendency to form biofilms, which are substances that help organisms adhere to various surfaces. Once biofilms are formed, they are pretty difficult to destroy, which improves the efficiency of Pseudomonas Aeruginosa in pathogenic activity.

Significance

P. aeruginosa is considered one of the most common gram-negative infections in hospital settings, especially in settings consisting of weaker immune systems. [3] Exposure to this microorganism can be contracted all over the body, and result in multiple bodily effects, such as pneumonia in the respiratory tract and osteomyelitis in the bones and joints. This bacteria can be found in water, which can lead to eye and ear infections by direct contact with this microorganism. It can also cause mild illnesses and rashes in both children and adults. Therefore, it is essential to maintain clean environments for patients and healthcare providers because P. aeruginosa can easily spread from patient to patient [3]. These infections are generally treatable with antibiotics, but are becoming more difficult to treat overtime due to antibiotic resistance.

Genome Structure

We identified the organism using PCR and gene sequencing of its rRNA genes below.

This organism has one circular chromosome and divides by binary fission.

Physiology and Pathogenesis

P. aeruginosa is an opportunistic pathogenic microorganism. It is the most common cause of burn injuries and can spread through contaminants, especially in health care settings [2]. Within low phosphate levels, it can induce release of lethal toxins to the intestinal tract and cause severe damage to the host cells. This occurrence can be counteracted by exposing patients to an excessive level of phosphate.

Some laboratory tests were performed in order to lead to the correctly identified microorganism within the tested soil.

P. aeruginosa:

- Gram-negative: This means it has an inner layer of peptidoglycan in its cell wall as well as an outer layer of lipoprotein and lipopolysaccharides.

- Endospore negative: It does not form spores when the environment is unfavorable. Therefore, it does not produce spores that increase pathogenicity that make it harder to destroy in the body without also harming good cells.

- Produces the enzyme deaminase, which removes the amine group from the amino acid phenylalanine and releases it as ammonia, producing phenylpyruvic acid as a result. When 10% ferric chloride is added to this medium, the presence of phenylpyruvic acid causes the media to turn dark green, a positive test result for deaminase (see picture below)

- Causes 10-20% of nosocomial infections (e.g., urinary tract infections and respiratory pneumonia) and is especially pathogenic to immune-suppressed patients such as burn victims, organ transplants, cystic fibrosis patients, and those who have long stays in hospital settings. An infection can cause meningitis, endocarditis, septicemia and more. [1]

- Can be treated with aminoglycosides and penicillins. However, prompt attention is vital.
