(cause)

Dental Caries/Dental Plaque

(characteristics)

Over 300 species of microorganisms found around teeth

Ferment sugars and carbs into lactic acid which dissolve enamel

Form biofilms on teeth 

Periodontitis

(characteristics)

Initially causing Gingivitis

Eventually causes periodontitis 

Staph Food Poisoning

(characteristics)

Organisms from skin/nasal cavities of food handlers

Resistant to heat, salt, drying, and radiation 

Associated with temperature abuse

1-6 hours until nausea

Cause of food intoxication

Salmonellosis

(characteristics)

Heat sensative, but may contaminate food after cooking from cutting boards

Gastroenteritis

12-36 hour incubation

Nausea, abdominal pain, cramps, diarrhea

Infants hit hardest

Food infection

Typhoid Fever

(characteristics)

Oral route: water, food

2 week incubation

microbes multiply in phagocytic cells

High mortality rate

Vaccine: live oral of killed

Systemic disease

Vibrio Gastroenteritis Cholera

(characteristics)

Crustaceans, shrimp, crabs Incubation 24 hours

Vomiting and diarrhea

Diarrhea= rice water; watch for dehydration, can lose 3-5 gallons/day, shock sets in

Must replace fluids and electrolytes

Enterotoxigenic E. coli

gastroenteritis  (ETEC)

(characteristics)

Most E. coli are not causes of gastroenteritis

Travellers diarrhea

Infant diarrhea

Not invasive

Enteroinvasive E. coli

gastroenteritis  (EIEC)

(characteristics)

Invade intestinal wall

Inflammation, fever, dysentery                     

Enterohemorrhagic E. coli

gastroenteritis  (EHEC)

(characteristics)

Hemorrhagic Colitis (bleeding from colon), no fever

Complication: Hemolytic uremic syndrome

5-10% of children develop, high mortality rate

Campylobacter gastroenteritis

(characteristics)

Food borne, normall flora of cattle, meat and milk

Low infective dose (25 cells/gram)

2nd most common cause of diarrhea

Cholera

(characteristics)

Peptic ulcer disease

(characteristics)

Gastric and Duodenal ulcers

Can grow in highly acidic habitat

Produces urease which converts urea to ammonia (basic compound) and neutralizes the immediate area around the cell

Longer you live, more likely to infect, may be spread by water

Bacillus cereus gastroenteritis

(characteristics)

Pseudomembraneous colitis

(characteristics)

Broad Spectrum Antibiotic associated colitis, disturbs normal flora in gut

Cytomegalovirus disease

(characteristics)

Hepatitis B

(characteristics)

Hepatitis C

(characteristics)

Hepatitis D

(characteristics)

Hepatitis E

(characteristics)
