Habitat Information

The location of the soil sample was collected behind an apartment complex inside of a ditch. Due to recent rain of approximately two days the soil was silty clay, with 1 to 3 percent slopes. The depth of digging was from the surface to 2 1/2".

Description and Significance

Pseudomonas aeruginosa is a gram negative opportunistic bacteria that can be found in soil, water, plants, animals, humans, hospitals and other places that contain moisture. Colony morphology is pale brown/metallic sheen color, flat, irregular, entire smooth appearance, sweet corn tortilla odor. The cellular shape of P. aeruginosa is gram negative bacilli rods, motile, obligate aerobes. P.aeruginosa is the very common cause of infections naturally resistant to a large range of antibiotics. Immunocompromised patients with cancer, HIV/AIDS, cystic fibrosis, hospitalized patients, and individuals in the burn unit at a hospital as well are at a bigger risk contracting this bacteria.

Genome Structure

P.aeruginosa has a genome size of 5.2 to 7 million base pairs(Mbp) with 65% Guanine and Cytosine content. It has a single and supercoiled circular chromosome in the cytoplasm and variable number of plasmids.

Cell Structure, Metabolism and Life Cycle

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

Physiology and Pathogenesis

Biochemical characteristics, enzymes made, other characteristics that may be used to identify the organism; contributions to environment (if any).
If relevant, how does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
