Meningitis
Inflammation of the meninges.
Encephalitis
Inflammation of the brain. Fever, headache, stiff neck.
Bacterial meningitis
Haemophilus (genus)
occurs mostly in children (6 months to 4 years)
Haemophilus
Name the genus that causes Bacterial meningitis.
Neisseria
Name the type of meningitis that begins as throat infection and rash. Vaccine against some serotypes is available.
Streptococcus pneumoniae
What type of meningitis is most common in child from 1 month to 4 years old.
Listeria
Name the genus that causes Listeriosis.
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.
virus
What type of organism causes influenza?
Dtap
What is the prevention of getting Tetanus?
Meningitis
Encephalitis
Listeriosis
Tetanus
Botulism
Leprosy
What are all of the bacterial diseases of the Nervous system?
Botulism
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.
Leprosy
What is the disease name?

Hansen's disease
genus: mycobacterium

found on footpads of mice & armadillo tissues.

2 forms:
Tuberculoid/Neural form
Lepromatous/Progressive form
Tuberculoid/Neural form of Leprosy
Bacteria grow in peripheral nerves (PNS)-> Regions of skin lose sensation and are surrounded by a border of nodules (rarely contagious)
Lepromatous/Progressive form of Leprosy
Infected skin cells -> Disfiguring nodules (Lepromas) & ends up causing Tissue necrosis
Mycobacterium
Name the genus that causes Lepromatous?
Mycobacterium
Name the genus that causes Leprosy?
Botulism
Ingestion of exotoxin in food.
Symptoms occurs: Double/blurred vision, slurred, speech, labored breathing, vomiting difficulty swallowing -> flaccid paralysis -> death due to respiratory and cardiac failure. (food intoxication)

Name disease.
Infant botulism
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
How is Leprosy transmitted?
