Gram negative. Part of the normal flora of the gut. Some strains produce exotoxin which cause diarrhea. Most well studied bacteria.
Enterococcus faecium
Gram positive. Vancomycin-resistant enterococcus is antibiotic resistant.
Enterococcus faecalis
Gram positive. Group D streptococcus.
Salmonella enteriditis
Gram negative. Causes food poisoning.
Streptococcus pyogenes
Gram positive. Causes group A streptococcal diseases.Produces large zones of beta-hemolysis on blood agar.
Staphylococcus aureus
Gram positive. Causes toxic shock syndrome, streptococcal pneumonia, meningitis, and a host of other opportunistic diseases. Also a common source of nosocomal disease.
Staphylococcus agalactiae
Gram positive. Urinary tract infection
Streptococcus mitior
Gram positive. Located in mouth.
Streptococcus mitis
Gram positive. Alpha hemolytic. Inhibits the mouth. Can cause endocarditis.
Bartonella henselae
Gram negative. Causes cat-scratch disease.
Eikenella corredens
Gram negative. Pits agar. From human bite.
Clostridium tetani
Gram positive. Anaerobic. Creates the toxin tetanospasmin. Which causes tetanus. Forms endospores
Clostridium perfringens
Gram positive. Anaerobic. Ubiquitous in soil. Forms endospores.
Bacillus anthracis
Gram positive facultative aerobe. Forms endospores which, if inhaled, cause an anthrax infection. Anthrax toxin causes sudden septiciemia and death.
Bacteroides fragilis
Gram negative aerobe.Common in intestines
Porphyromonas gingivalis
gram negative. Infects gingival of mouth
Neisseria meningitidis
Gram negative. Can cause meningitis if it enters the meninges.
Actinomyces israeli
Gram positive. Causes Actinomycosis, which causes multiple painful swellings filled with pus.
Vibrio cholerae
Gram negative curved rod which causes cholera. Choleragen exotoxin causes symptoms of rice water diarrhea, which is causes by the increased production of mucus and expulsion of water and electrolytes. Usually found in contaminated seafood due to it's water-borne nature. Tetracycline is the drug of choise.
Vibrio vulnificus
Gram negative. Similar to cholera. Vomiting, diarehha, abdominal pain and blistering dermatitis.
Campylobacter jejuni
Gram negative, curved rod shaped,. microaerophile. Most common cause of gastroenteritis. Usually self-limiting. Can trigger Guillain-Barré syndrome, an autoimmune disease marked by ascending paralysis.
Yersinia pestis
gram negative rod shaped bacteria. Cause of the bubonic, pneumonic, and septicemic plague.
Treponema pallidum
Gram negative spirochete. Causes Syphilis and yaws.
Borrelia burgdorferi
Causes lyme disease.
Mycoplasma pneumoniae
Causes slow progression pneumonea.
Chlamydia trachomatis
Gram negative. Causes chlamydia, an STD, which presents with discharge. Infects the genitals and eyes.
Coxiella burnetii
Intracellular parasite. Causes Q fever.
Enterobacter aerogenes
Gram negative, oxidase negative, catalase positive bacteria. Causes oppertunistic infections. Normally found in gastrointestial tract, but may become pathogenic in response to certain antibiotic treatment or surgery.
Klebsiella pneumoniae
Gram negative, lactose fermenting, facultative anaerobe. Part of the normal flora of the mouth, skin, and intestines. Can cause pneumonia in aspirated patients (alcoholics), but more commonly causes urinary tract and wound infections. Also a nosocomial infection.
Salmonella enterica typhi
Gram negative flagellated. Causes typhoid fever.
Salmonella enterica typhimurium
causes gastroenteritis called sallmonelosis.
Streptococcus pneumoniae
gram positive. Alpha-hemolytic. Causes pneumonia, bacterial meningitis, endocarditis, and a host of other diseases depending on site of infection. Encapsulates itself to avoid phagocytosis.
Staphylococcus epidermidis
Gram positive. Oppertunistic infector. Catalase positive. Part of the normal flora of the skin.
Streptococcus mutans
Gram positive. Facultative anaerobe. Caused dental carries in the presence of sucrose.
Streptococcus salivarius
Gram positive. Found on the tongue. Rarely infectious.
Actinobacillus actinomcetemcomitans
AKA Aggregatibacter actinomycetemcomitans. Gram negativefacultative anaerobic, non motile rod. Found in severe infections of the oral cavity like periodontosis.
Pasteurella multocida
Gram negative coccobacillus. Infects due to dog bites.
Spirillum minor
AKA Spirilum minus. Rat-bite fever
Clostridium botulinum
Gram positive , rod shaped, strict anaerobe. Produces botulism toxin, a highly potent and deadly toxin for humans. C. sporogenes is almost exactly the same, except it does not produce the botulism toxin.
Clostridium difficile
gram positive, spore forming, anaerobic rod shaped. Causes pseudomembaneous colitis where a pseudomembrane is erected inside the gut when other normal flora is killed off. Vancomycin must be administered early, or the pseudomembrane has to be surgically removed if established. Causes offensive smelling diarrhea, fever, and abdominal pain.
Bacillus cereus
Gram positive, rod shaped, beta-hemolytic. Causes food borne illness is a small number of cases.
Bacillus thuringiensis
Gram positive. Produces Bt toxin, which is an organic insecticide.
Fusobacterium nucleatum
filamentous, anaerobic, Gram-negative bacteria.Found in cases of periodontitis.
