- A. Pseudomonas aeruginosa B. Escherichia coli C. Vibrio cholerae D. Haemophilus influenzae E. Legionella pneumophilia F. Salmonella enteritidis G. Campylobacter jejuni H. Bacteroides I. Helicobacter pylori Which of the above options correctly matches the description: Non-fastidious non-fermentor Toxin mediated disease Leads to an increase in intracellular cAMP levels Leads to decreased Sodium influx and increased chloride efflux in intestinal epithelial cells Leads to rice stool diarrhoea

Helicobacter pylori Which of the above options correctly matches the description: Fastidious Can cause meningitis (if capsulated) but now rare due to HIB vaccine Grows well on chocolate agar Unencapsulated strains are common in COPD and pneumonia patients

Helicobacter pylori Which of the above options correctly matches the description: Fastidious Resides naturally in water reservoirs Water must be heated to 60 degrees Celcius to remove bacteria Intracellular pathogen
- A. Pseudomonas aeruginosa B. Escherichia coli C. Vibrio cholerae D. Haemophilus influenzae E. Legionella pneumophilia F. Salmonella enteritidis G. Campylobacter jejuni H. Bacteroides I. Helicobacter pylori Which of the above options correctly matches the description: Commonest cause of bacterial gastroenteritis in the UK Classed as non-fastidious non-fermentor Natural host is birds
- Decide if each bacteria or genus will give rise to a food associated infection or food poisoning. Remember, food-associated infection means that the food is merely a vector by which the bacteria enter the body to cause disease. Without the food, the bacteria would be unable to enter the body. Food poisoning entails toxins produced by bacteria to be in the food. The bacteria themselves may be absent from the food.

Helicobacter pylori Which of the above options correctly matches the description: Non-fastidious fermentor Genus can cause typhoid fever This species can cause gastroenteritis

- A. Pseudomonas aeruginosa B. Escherichia coli C. Vibrio cholerae D. Haemophilus influenzae E. Legionella pneumophilia F. Salmonella enteritidis G. Campylobacter jejuni H. Bacteroides I. Helicobacter pylori Which of the above options correctly matches the description: Gram negative anaerobic bacillus Tends to be involved in poly-microbial infections
- A. Pseudomonas aeruginosa B. Escherichia coli C. Vibrio cholerae D. Haemophilus influenzae E. Legionella pneumophilia F. Salmonella enteritidis G. Campylobacter jejuni H. Bacteroides I.

How to use this module
To use a Qedoc learning module, the following procedure is recommended:
- Really easy: click the click here to launch hyperlink at the top right of the page. Then just wait and click your way (if necessary) through any dialogue screens. The module will launch straight off the web.
