    Study Notes

    Listeria monocytogenes - CryoCrawler

    • Powers: Thrives in cold environments, avoids enemies at room temperature but slows down in warmer conditions.
    • Nemesis: Pasteurization, high heat eliminates
    • Mission: Targets vulnerable populations (pregnant women, newborns, immunocompromised).

    Corynebacterium diphtheriae - Gray Shroud

    • Powers: Creates a thick, leathery membrane to weaken defenses; produces toxic energy blasts.
    • Weakness: Antitoxins and vaccines are effective.
    • Mission: Targets vital systems like the heart and nerves.

    Corynebacterium jeikeium - Skin Sentinel

    • Powers: Hides in skin flora; attacks weakened barriers (prosthetic devices); targets heart and bloodstream.
    • Nemesis: Sterile Shield (keeps infections at bay)
    • Mission: Seizes opportunities in compromised systems.

    Gardnerella vaginalis - Clue Commander

    • Powers: Disrupts environments with bacterial vaginosis (green, frothy); uses imbalance as signals.
    • Nemesis: pH Balancer (restoration of harmony)
    • Mission: Operates in stealth mode, leaving behind "Clue cells".

    Bacillus spp. - Sporeshifter

    • Powers: Survives extreme conditions, uses environment-resistant spores; contaminates labs.
    • Weakness: Sanitation Squad's cleaning efforts.
    • Mission: Blends in, strikes in unexpected moments.

    Bacillus anthracis - Black Plague

    • Powers: Tri-form attack (pulmonary, cutaneous, GI) using spores as deadly ammunition.
    • Nemesis: Vaccine Vindicator and Antibiotic Avenger
    • Mission: Inflicts devastation on human and animal populations.

    Bacillus cereus - Spore Chef

    • Powers: Causes food poisoning by planting spores in rice/other meals; survives high heat.
    • Weakness: Cold Storage Guardian (proper refrigeration).
    • Mission: Strikes at the dinner table.

    Clostridium spp. - Anaerobe Alliance

    • Powers: Thrives in oxygen-free environments; creates chaos in bowel, soil, vegetation.
    • Nemesis: Oxygen Overlord and Hygiene Hero
    • Mission: Remains hidden until ideal opportunity arises.

    Clostridium perfringens - Gas Wraith

    • Powers: Causes tissue necrosis through gas-producing exotoxins; overwhelms opponents quickly.
    • Weakness: Surgical removal of infected tissues, antibiotic forcefields.
    • Mission: Invades wounds, causing gangrenous devastation.

    Clostridioides difficile - Biome Breaker

    • Powers: Lurks until gut microbiome is disrupted; causes bloody diarrhea and pseudomembranous colitis.
    • Nemesis: Probiotic defender (restoring balance)
    • Mission: Exploits weakened ecosystems.

    Clostridium tetani - Lockjaw

    • Powers: Produces neurotoxin that locks muscles in contraction/relaxation after a wound infiltration.
    • Weakness: Vaccines and neutralizing agents
    • Mission: Causes chaos through spasms.

    Clostridium botulinum - NeuroToxinator

    • Powers: Releases neurotoxin (paralyzes) through improperly processed foods
    • Weakness: Proper cooking and botulinum antitoxin
    • Mission: Silently contaminates canned goods.

    Neisseria gonorrhoeae - The Pathogen Prince

    • Powers: Highly infectious, acute pyogenic (pus-producing) infection of skin mucosa (endocervix/urethra). Evokes Pelvic Inflammatory Disease (PID).
    • Weakness: Ceftaroline paired with Azithromycin, sensitivity to drying and temperature changes.
    • Mission: Infects mucosal surfaces.

    • Weakness: Decongestant shields, targeted antibiotics
    • Mission: Infects respiratory tracts, targeting vulnerable hosts.

    • Powers: Emerges from soil/water; brings danger.
    • ...(details needed for this organism to be clarified)

    Streptococcus spp. - The Chain Guardian

    • Powers: Defends upper resp. and intestinal tracts as normal flora, Gram-positive cocci in chains.
    • Weakness: Often blamed for diseases caused by more aggressive family members.
    • Mission: Maintains balance of microbiome.

    Enterococcus spp. - The Intestinal Ally

    • Powers: Resides as normal intestinal flora (fecal origin); causes UTIs, endocarditis, wound infections.
    • Weakness: Not a natural fighter; opportunistically strikes by weaknesses in the immune response.
    • Mission: Protects the gut, occasionally spreading

    Streptococcus pyogenes (Group A) - The Scarlet Striker

    • Powers: Causes strep throat, scarlet fever, cellulitis; manipulates immune response.
    • Weakness: Humans are only reservoir, limited to direct human contact.
    • Mission: Wreaks havoc on the human body.

    Streptococcus agalactiae (Group B) - The Neonatal Nemesis

    • Powers: Colonizes female genital tract (10-30%); infects newborns (meningitis, septicemia, pneumonia); opportunistic in elderly/immunocompromised (UTIs, bacteremia).
    • Weakness: Host vulnerability is key to establishing infection
    • Mission: Launches silent attacks on newborns and weakened individuals.

    Streptococcus pneumoniae - The Lancet Knight

    • Powers: Causes otitis media, pneumonia, meningitis, sinusitis; resides as normal flora in upper respiratory tract.
