SAC Stuff -Pathogen spread

Question 1

physcial

Answer 1

determines the structre of a pathogen through a microscope

Question 2

phenotypic

Answer 2

1. selective media - agar plate for specific pathogens to grow
2. Biochemical - a series of tests to determine the species and genus

Question 3

immunological

Answer 3

1. serology - presence of antigens in a persons serum
2. ELISA via the sandwhich method

Question 4

identifiying pathogens

Answer 4

1. physical
2. phenotypic
3. immunological
4. molecular

Question 5

ELISA

Answer 5

1. antibodies specific to a pathogen are attched to a plate
2. the serum sample is then put on that plate, which makes the pathogen antigen attach to the antibodies
3. a colour changing antibody with an enzyme is added, which will bind to any anigen-antibdy complexes formed
4. a substrate is added which will react with the enzyme-antibody and will make the colour change occur, so it illuminates if any pathogenic antigens are present

Question 6

e

molecular

Answer 6

whole genome sequencing - provides detailed informaion about the pathogen

Question 7

modes of transmission

Answer 7

1. Airborne transmission
2. droplet transmission
3. direct physical contact
4. indirect physical contact
5. faecal-oral transmission

Question 8

Controlling disease transmission

Answer 8

1. prevention - hygeine
2. screening - testing
3. quaratine
4. identification
5. transmission
6. treatment
