Disease Acquired Through the Alimentary System
Bacterial
Dental Caries (teeth)
Gingivitis (gums)
Periodontal Disease (gums)
Streptococcus mutans
Secrete dextran from sucrose form biofilm then harden become dental plaque.
Sugars fermented become acidic and erode tooth enamel. Bacteria enter eroded space and invade second layer of tooth(dentin) and pulp.
Porphyromonas gingivalis
Secrete gingipains
(digesting enzyme, breakdown gingival tissue)
Cause tooth to loose and fall out due to gum recede.
Dietary Habits
Hormone (pregnancy)
Poor dental hygiene
Physical examination
Scaling (plaque removal)
Removes cavities - filled with filling
Root canal treatment
Dental check-up twice a year
Brush & floss teeth twice a day
Fluoridation of water
Peptic Ulcer Disease
Helicobacter pylori
Gastric acid destroy lining of stomach tissue cause ulcer.
Due to the ability of the bacteria pass through stomach acid and invaded the epithelial cells.
Urease neutralize stomach acid
Adhesins facilitate attachment to gastric cells
Direct contact of contaminated objects
Medications (pain killer or steroid)
Dietary habit (alcohol, spicy food)
Blood test
Urea breath test
Endoscopy
Antibiotics treatment
(amoxicillin, omeprazole, clarithromycin)
Medication relief acid reflux
(antacid, calcium carbonate)
Avoid food could trigger acid reflux (spicy/coffee)
Proper handwashing
Bacterial Gastroenteritis
Shigella
Bacteria invades cell host, multiple in cytosol as well as in neighboring cells.
Shiga toxin or exotoxin inhibit protein synthesis of host cells.
Enterotoxins attached on epithelial cells trigger diarrhea.
Recorded 165 million cases worldwide every year.
Foodborne transmission
Direct contact (fecal oral)
Stool sample culture
Treatment by symptoms (antidiarrheal, antiemetics)
Maintain/improve body fluid medication (Oral Dehydration Salt, IV drip)
Prescribes antibiotics (certain cases)
Proper handwashing
Proper food handling
Escherichia coli
Campylobacter jejuni
Adhesins
Cytotoxins
Endotoxin (Lipid A)
Common source of infection from chicken
Closridium difficile
Release two type of toxin
Toxin B
Toxin A
Unpleasant smell of stool
Bloody stool
Antibiotic abuse
Immunocompromised induvidual
Consume antibiotics as prescribe.
Practice good hygiene
Increase normal flora in intestine by taking probiotics
Salmonella enterica
Attach to host cell, inhibit cell function result in cell death.
Contaminated chicken eggs
Typhoid vaccine
Vibrio cholerae
Opportunistic Pathogen
Contaminated water
bacteria survive in both salt and fresh water
Observe the characteristic of stool
Rice-water stool
Abdominal pain
Diarhea
Vomit
Nausea
Bacterial Food Poisoning
(intoxication)
Staphylococcus aureus
Five Enterotoxin
Motility
Adhere to cell host
Invade host cell
Encounter nutrients
