|
|
|
Listeriosis
|
Several forms of disease: Meningitis: headaches, stiff neck, delirium -> coma.
Bacteremia: Increased # of monocytes Infected uterus: Flu like symptoms Neonatal fetal infections: Disseminated absecesses and granulomas. Typically fetus is aborted or stillborn. |
|
|
Consumption of animal products: raw milk, cheese, and meat.
|
What is the mode of transmission for Listeria?
|
|
|
Tetanus
|
Name disease.
Common is soil Produces: Tetanospasmin (toxin) (causes sustained muscle contraction, blocks relaxation of antagonistic muscles) Exotoxin: 2nd most potent toxin known. |
|
|
Tetanus.
|
Name disease that has symptoms and signs that involve:
Spores in wound -> muscle stiffness and spasm -> muscles of face and neck contract (lockjaw/risus sardonicus) -> arching of the back -> respiratory failure. |

|
genus: clostridium
Found in soil and fresh water sediments. produces exotoxins (Botulin) |
|
|
clostridium
|
What is the genus name that causes Botulism?
|
|
|
Botulin
|
a neurotoxin that blocks the release of acetylocholine and provents transmission of nerve impulses across the synapse.

|
|
|
Lepromatous/Progressive form of Leprosy
|
Infected skin cells -> Disfiguring nodules (Lepromas) & ends up causing Tissue necrosis

|
ingesting spores of botulism
Organism may grow in the intestinal tract of infants. Approx. 30% of cases from honey |
|
|
Ingestion of endospores (or viable organisms) in food.
food infection |
How is botulism transmitted?
|
|
|
Multiple skin contacts or respiratory droplets
|
