Cellular appendages that are extensions of the cell envelope (not flagella or pili); they increase surface area for nutrient uptake or attachment; seen in bacteria like Caulobacter.
Gram-negative, spiral or curved soil bacterium associated with plants; fixes nitrogen and promotes plant growth in the rhizosphere.
Small Gram-negative obligate intracellular bacteria, often arthropod-borne; cause diseases like typhus and Rocky Mountain spotted fever.
Obligate intracellular Gram-negative bacteria infecting leukocytes; typically tick-borne; cause ehrlichiosis.
Gram-negative soil bacteria that form root nodules on legumes and fix nitrogen in symbiosis with the plant.
Aquatic Gram-negative bacteria notable for a stalk (prostheca) and holdfast for attachment; shows a dimorphic life cycle with stalked and swarmer cells.
Gram-negative, often vector-associated bacteria infecting red blood cells and endothelial cells; includes agents of cat scratch disease and trench fever.
Small Gram-negative coccobacilli; facultative intracellular pathogens causing zoonotic brucellosis, often from livestock or unpasteurized dairy.
Gram-negative soil bacteria known for transferring DNA (Ti plasmid) into plants, causing crown gall disease; widely used in genetic engineering.
Rigid spiral-shaped bacteria; distinct from flexible spirochetes; also a genus name.
Gram-negative nitrifying bacteria that oxidize nitrite (\(NO_2^-\)) to nitrate (\(NO_3^-\)) in the nitrogen cycle.
Small Gram-negative coccobacilli; includes B. pertussis, the cause of whooping cough (pertussis).
Gram-negative diplococci; includes N. gonorrhoeae (gonorrhea) and N. meningitidis (meningitis and meningococcemia).
Large family of Gram-negative rods, facultative anaerobes living in intestines; includes Escherichia, Salmonella, Shigella, Klebsiella, and others.
Gram-negative rod; normal gut microbiota but some strains cause diarrhea, urinary tract infections, sepsis, and meningitis.
Gram-negative rods, often encapsulated; cause opportunistic pneumonia and UTIs; known for antibiotic resistance like KPC producers.
Gram-negative rods with motile swarming growth; can cause UTIs and produce urease, linked to kidney stone formation.
Small Gram-negative coccobacillus; F. tularensis causes tularemia; zoonotic and transmitted via ticks, deer flies, or animal contact.
Gram-negative rods causing gastroenteritis and enteric fever (typhoid from S. Typhi); associated with poultry, eggs, and reptiles depending on serotype.
Produces botulinum toxin causing flaccid paralysis (botulism); often from improperly canned foods or infant exposure to spores/honey.
Produces tetanospasmin toxin causing spastic paralysis (tetanus); associated with wound contamination.
Gram-positive rod; foodborne pathogen causing meningitis and sepsis in newborns, elderly, and immunocompromised; grows at refrigerator temperatures.
Bacteria lacking a cell wall, pleomorphic and resistant to beta-lactams; includes M. pneumoniae, cause of walking pneumonia.
Gram-negative aerobic rod; metabolically versatile opportunistic pathogen causing infections in burns and cystic fibrosis lungs; forms biofilms and is often antibiotic resistant.
Gram-negative curved/spiral rod; microaerophilic; colonizes the stomach and is linked to ulcers and gastric cancer risk.
Gram-negative curved/spiral rod; microaerophilic; common cause of bacterial gastroenteritis linked to poultry; associated with Guillain–Barré syndrome.
Gram-negative bacteria found in aquatic environments; grow in amoebae; cause Legionnaires’ disease, an atypical pneumonia linked to water aerosols.
Small Gram-negative predatory bacteria that invade and consume other Gram-negative bacteria; studied as a potential living antibiotic.
