Question 1

modes of transmission

Answer 1

way of spreading of the pathogenic microorganism from the SOI to a suitable portal of entry of the susceptible host

Question 2

minimum infectious dsoe

Answer 2

lowest amount of pathogenic microorganism sufficient to cause infection

Question 3

SOI

Answer 3

places where a large amount of microorganism are located just before the outbreak in susceptible groups of animals

Question 4

mode of spread

Answer 4

way of transmitting a pathogenic microorganism from the source to a suitable host

Question 5

2 ways of spread by arthropods

Answer 5

1: biological transmission
- transmission of a pathogenic microorganism that multiples in the arthropod

2: mechanical transmission
- transmitting pathogen to the contaminated surface of the insect. or when the proboscis is contaminated with blood during feeding on a sick animal and then goes and passes it around
