opportunistic pathogen


Pseudomonas aeruginosa

Pseudomonas aeruginosa is a nonfermentative gram-negative bacillus. This bacterium is ubiquitous in soil and water, and on surfaces in contact with soil or water. Pseudomonas aeruginosa is an opportunistic pathogen, meaning that it exploits some break in the host defenses to initiate an infection. It causes urinary tract infections, respiratory system infections, dermatitis, soft tissue infections, bacteremia, bone and joint infections, gastrointestinal infections and a variety of systemic infections, particularly in patients with severe burns and in cancer and AIDS patients who are immunosuppressed.

Key characteristics: Gram(-), catalase(+), oxidase(+), motility(+), aerobic, produces pigments (green and blue), grows at 42°C.


1. Vogesella indigofera, obtained from a pond brimming with highly toxic waste.

2. Pseudomonas aeruginosa, an opportunistic pathogen that can also be used in the bioremediation of oil spills.

3. A battle between Serratia marcescens (red) and the common soil bacterium, Bacillus mycoides (white). The Serratia seems to produce an antibiotic to protect itself from the invading Bacillus strain. 

Samus' Journey: The Argument

The small human child slept, finally, face still slick with tears, in the quiet chamber of the Zebes Facility. Down a long hallway made of slick stone, dimly lit by old and broken glowpanels, a raspy pained voice could be heard, speaking in the Chozo trade language. The only language left to the slowly dying species, as they consolidated their aging cultures for their overall survival in the wake of reproductive loss.

“Are your scans conclusive?”

The second voice, cold, barely perceptible inflection flaws and a slight flanging marking it as artificial responded.

“My scans are always conclusive. The human will not survive here.”

Two hooded figures stood before a floating sphere, with a bright red eye in the center. Vines filled the wide open space of the rocky facility, old architecture at odds with the advanced technology of the computer systems contained within.

“What about the additional data?” the taller figure asked.

“The human possesses Genetic Containment Locus 23.2 and Small Gamete Creation ability, along with seeding ability. This is typically used in Dominant Federation Cultures to apply a sociocultural label of Man or Male to a human,” the sphere’s red eye flickered, “however, she is insistent on being spoken of with indirect object referral phrases that typically are used to describe Female Or Woman labeled humans in Federation cultures. My Database contains several references on this phenomenon in the human species. She may seek bodily modification as a result.”

“Grey Voice, what if we simply incorporated some of the changes she may desire in with the modification process,” the shorter hooded figure said, taloned hands clasped before him, “with consultation to the hatchling of course.”

“This is pretending for a moment that she even would consent to having her entire genetic structure modified, Old Bird,” Grey Voice said with bitterness, “or that the process would even be successful. The rate is discouraging to say the least.”

“The human is lacking in brain development due to age. Decision making processes will be impacted.” The sphere said, even as it floated up wards towards the machinery attached to the back of the wall.

“Her very survival depends on it. And perhaps, ours as well,” Old Bird said, “she will not live long on Zebes, the very atmosphere is difficult for her body to process. Her emotional distress from the trauma of losing her entire family and colony to Space Pirate violence is certainly not helping her immune system or overall health. I am amazed that she has not caught an opportunistic pathogen already”

“I am more than a little disturbed at the morally questionable nature of putting the fate of our species on a human hatchling’s back, while she is not competent to consent to it,” Grey Voice said with vehemence.

“You would rather she died on this planet, before we can transport her to a safer place or the Federation?” Old Bird said.

Grey Voice remained silent, clicking a single talon against another on his hand.

“A decision must be made,” the sphere floated back down, “I require your authorization to continue. Her probability of survival reduces by a factor of 10 every microcycle we delay.”

Grey Voice made a noise in the back of his throat and clicked his beak together.

“Very well,” he said grinding his talons together with agitation, “you are correct, we have no choice.”

He looked up at the sphere.

“Mother Brain, make your preparations. If Samus consents, she will be made as one of us and human both.”
