Term
Bacillus anthracis[image] |
|
Definition
aerobic gram + rods; exists as veg cell and spores, but spores cause anthrax (rare); three routes of infection incl cutaneous (black eschar), inhalation (lung edema, shock, and death), and gastrointestinal (abdominal pain, bloody vomit, and diarrhea) |
|
|
Term
|
Definition
aerobic large gram + rods; veg cell and spores; spores can withstand heating; upon cooling spores germinate producing veg cells that produce 2 enterotoxins; infected meat produces diarrhea; infected starchy foods produce emesis; symptoms last 24 hours in both cases |

Term
Corynebacterium diptheriae[image] |
|
Definition
small narrow aerobic gram+ rods; many people carry in nasopharynx; transmission is respiratory droplets; rare in immunized population; toxin kills cells in pharynx with pseudomembrane that can cause airway closure; most common cause of death is myocardial damage |

Term
Listeria monocytogenes[image] |
|
Definition
small; grows in a wide range (incl low) of temps; Primarily food poisoning from dairy, raw meats; Person to person can occur during labor and delivery following infection of the birth canal causing fetal listeriosis; Fetus could develop septicemia, meningitis, or encephalitis; pregnancy could result in still birth; |

Term
Clostridium botulinum[image] |
|
Definition
anaerobic spore forming gram + rod; in soil and water; spores typically contaminate canned foods and produce highly toxic neurotoxin causing flaccid paralysis; often in honey (infant botulism); rarely wound botulism |

Term
|
Definition
anaerobic spore forming gram + rods; found in soil; spores can survive for long periods of time; rare (vaccination); tetanospasmin - spastic paralysis characterized by lockjaw, arching of back, and respiratory muscle spasms; transmitted when spores enter wound and germinate veg cells releasing neurotoxin |
