2. Introduction

Pseudomonas oryzihabitans is a rod-shaped, Gram-negative bacterium known to cause infections in humans, in both immunocompromised and non-immunocompromised individuals. Some infections that P. oryzihabitans can cause include nosocomial (hospital-acquired) sepsis, bacteremia, endophthalmitis, and peritonitis (1). In other unique cases, P. oryzihabitans has been documented to cause urinary tract infections and green nail syndrome (2, 3). P. oryzihabitans is commonly found in hospital settings, on respiratory equipment and unsterilized medical tools (1). In nature, P. oryzihabitans can be found in moist environments, like soil, rice paddies, running or standing water, and groundwater (4,5). In these environments, P. oryzihabitans has potential to promote root growth via suppressing parasitic nematode populations, making it easier to grow and maintain certain crops (6). Additionally, P. oryzihabitans has a positive growth effect on members of the cucurbit family affected by Bacterial Fruit Blotch disease (BFB) (7). P. oryzihabitans also negatively impacts the growth of Muskmelon by causing stem and leaf rot (8). Overall, in this paper we discuss how P. oryzihabitans is a multifaceted organism that plays various roles ecologically, agriculturally, and medically that has not been compiled previously.

3. Genome structure

Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence?

4. Cell structure

Interesting features of cell structure. Can be combined with “metabolic processes”

5. Metabolic processes

Describe important sources of energy, electrons, and carbon (i.e. trophy) for the organism/organisms you are focusing on, as well as important molecules it/they synthesize(s).

6. Ecology

Habitat; symbiosis; contributions to the environment.

7. Pathology

How does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
