Infectious Disease Series 3
Disease Detectives [PDF 150KB]
Disease detectives look at clues from tiny germs to unravel the mystery of disease.
Foodborne Disease [PDF 156KB]
Foodborne diseases are sometimes caused by tiny bacteria that makes us sick.
Gathering Evidence [PDF 145KB]
Doctors and nurses gather evidence from sick people to find out if food made them ill.
Finding Bacteria [PDF 151KB]
Microbiologists play an important role in solving the mystery of disease.
High-Tech Answers [PDF 139KB]
When microbiologists find disease-causing bacteria, they send them to a laboratory for DNA fingerprinting. These laboratories use high-tech equipment to make DNA fingerprints.
Bacterial Fingerprints [PDF 131KB]
Each type of bacteria has unique DNA which makes up a pattern of bands called a fingerprint.
PFGE Patterns [PDF 138KB]
The fingerprints that scientist use to identify bacteria are called Pulsed-Field Gel Electrophoresis (PFGE) Patterns.
Comparing Fingerprints [PDF 143KB]
After scientist at the public health laboratories have made a bacterial fingerprint, they share pictures of it with the PulseNet team.
Which Two Match? [PDF 151KB]
Once the PulseNet team has found all the DNA fingerprints that look the same, they make a dendrogram, or bacteria family tree.
Epidemiolgists [PDF 148KB]
If the PulseNet team finds matching bacterial fingerprints from several different patients, they alert the epidemiologists right away.
Preventing New Cases [PDF 155KB]
Always wash your hands before you eat.
Campylobacter jejuni [PDF 147KB]
This bacterium hangs out in bird droppings, raw milk, and untreated water.
E.coli 0157:H7 [PDF 146KB]
You can stop E. coli by never eating raw or undercooked hamburger or by not drinking unpasteurized milk and juice and by always washing your hands after touching raw meats.
Shigella [PDF 132KB]
Shigella, spreads to other people by contaminated salads, sandwiches, and water. To stop this disease, wash your hands before eating.
Listera [PDF 146KB]
Listera loves cool, wet places like soft cheese, sandwich meat, and hotdogs. Throw away foods that have passed the expiration date and be sure the food you eat is clean and fully cooked.
Salmonellosis [PDF 149KB]
You can stop Salmonella by eating foods that are clean and fully cooked. Always wash your hands before eating.
Separate [PDF 158KB]
Some foods have bad germs that can spread to other foods if we are not careful.
Chill [PDF 139KB]
Be cool. Chill out. Refrigerate promptly.
Cook [PDF 164KB]
The only way to be sure cooked food is safe to eat is by using a food thermometer.
Clean [PDF 152KB]
Washing your hands is one of the best ways to kill germs and keep them from spreading.
