Bacteria List Escherichia coli: gram- rod-shaped enterobacteriaceae found in lower intestine; can cause food poisoning; indicator of fecal pollution in water; most commonly used prokaryotic in lab; part of normal gut flora; produces diarrhea; facultative anaerobe, non-sporulating, non-motile; indicator of fecal pollution in water supplies Xanthomonas campestris: causes disease in stems, fruits, & other plants; can produce Xantham gum used in salad dressings & toothpaste; gram -, aerobe Yersinia pestis: gram -, the bacterium responsible for Black Death & bubonic plague; began in 1347; within 4 years killed 1/3 of Europe; person-to-person, by fleas, or rats; chills, fever, vomiting, diarrhea Bacillus anthracis: gram+, anthrax; spore forming; streptobacilli, non-motile 1 bacteria to be shown to cause disease; bacterium enters cut or intestines through contaminated meat ingestion; respiratory distress, fever, shock, die quickly Serratia marcescens: rod-shaped gram -, found in damp conditions (bathroom, etc.); pink/bright red pigmentation; found in urinary tracts & gastrointestinal systems; opportunistic pathogen; produces biofilm Saccharomyces cerevisiae: baker’s yeast for rising of bread; fermenting sugars into alcohol; diploid cell; only 1% of yeast infections are infected with yeast Clostridium botulinum: botox; botulism (muscular paralysis); gram+, rod-shaped, produces neurotoxin; grows in low pH; anaerobic; spore-forming rods; death by suffocation due to nerves no longer stimulate breathing Pseudomonas aeruginosa: gram-, leading opportunistic pathogen, green, rod-shaped cells; leaves green around the skin; resistant to many antibiotics; complicates 90% of cystic fibrosis cases Staphylococcus sp.: gram+, grape-like clusters Streptococcus sp.: gram+, spherical cell that form long chains; essential in industry & dairy processes; indicator of pollution; can cause scarlet fever, rheumatic heart disease, pneumonia Micrococcus sp.: gram+, wide range of environments, mainly on face, arms, hands, etc. Halobacerium: salt lovers Listeria sp.: gram+ rod-shaped bacilli; can be found in vegetables & processed foods Neisseria sp.: gonorrhea; affect mucosal surfaces of animals Neisseria meningitides: mild sore throat to fatal meningitis or septicemia Enterobacter sp.: gram- rod-shaped bacteria; non-coliform; pathogen than affects urinary & respiratory tracts Haemophilus influenza: gram - coccobaccilus, first free-living organism to have its entire genome sequenced; can cause meningitis, epiglottitis, pneumonia, arthritis, or osteromyelitis Campylobacter sp.: gram-, Human pathogen, chicken as an intermediate; spiral/corkscrew appearance Vibrio sp.: gram- curve (comma) rod-shaped; cholera toxin; associated w/ eating undercooked seafood; facultative anaerobes; test positive for oxidase & non-spore forming, motile with polar flagella Fusobacterium sp.: gram- rod-shaped bacilli; known for causing dental plaque; makes biofilms Treponema pallidum: syphilis; needs dark field microscope to identify Neisseria gonorrhoeae: gram- pathogen; causes gonorrhea & meningitis Haloarcula sp.: irregular red discs, archaea, grow in 40-45°C in salt waters (Dead Sea) Bifidobacteria sp: gram+ non-motile, anaerobic bacteria; used as probiotics (live bacteria with possible health benefits) Staphylococcus aureus: gram+; facultative anaerobe; causes of skin infections and found in the human respiratory tract; one of most common hospital-acquired infections; caused TSS in 1970’s Geobacillus stearothermophilus: hot spring bacteria; thermal vents or thermophilic habitats Streptococcus pneumonia: gram+; known for the cause of pneumonia; respiratory tract Chromatium sp: Winogradsky column: purple sulfur bacteria Lactobacillus sp.: fermenters; can cause greening of sliced meats by presence of hydrogen peroxide; convert lactose & other sugars to lactic acid Penicillium sp.: produce penicillin (an antibiotic) which kills/stops growth of some bacteria in body Penicillium roqueforti: fungus that can be isolated from soil, decaying organic substances, or plant parts; used for Roquefort cheese Penicillium camamberti: fungus used in Camembert & Brie cheeses; colonies form hard white crust Brevibacterium sp.: can be used in limburger cheese, foot odor Propionobacterium shermanii: used in cheese making to create CO bubbl2s ex. Swiss cheese Klebsiella sp.: rod-shaped with polysaccharide-based capsule; pneumonia, UTIs, & soft tissue infections Klebsiella pneumonia: human lung inflammation and hemorrhage; thick, blood mucoid sputum K. oxytoca: breaks done cyanide; opportunistic pathogen that can spread quickly E
