Bacterial Diseases Flashcards
1
Q
What are the routes of transmission for a bacterial virus?
A
- airborne
-droplet
-contact - vectors
-fomites (eg. clothes)
2
Q
What are the routes of infection?
A
- respiritory tract
- urinary tract
-oral - gastrointestinal tract
- skin contact
- mucosal
-wounds
3
Q
Host recognition of the bacterial cell wall?
A
- Cell wall contains Pathogen Associated Molecular Patterns
-PGN = Peptiglycan - LP = Lipoprotien
- LTA = Lipoteichoic acid (only gram positive)
- LPS = Lipopolysaccharide (only gram negetive)
4
Q
What is Contagious Equine Metritis?
A
- venereal disease of equines
notifiable - caused by a gram negative (harder to kill) bacteria
- transmitted by venereal contact (sexual)
-stallions are asyptomatic
5
Q
What are the symptoms of ?Contagous Equine Metris
A
- mares can be severely or chronically infected
- no signs of fever
- no syptems of sytematic clinical disease
-discharge
6
Q
How is contagious equine metris controlled?
A
- prevention (testing before breeding) (movement testing)
- cancelling breeding when known infected case occurs
7
Q
What type of bacteria causes leptospirosis?
A
gram negative
8
Q
How is leptospirosis transmitted?
A
- broken skin
-consumption or inhalation of contaminated water
9
Q
How is leptospirosis prevented?
A
vaccination of domestic animals (zoonotic)
10
Q
What is the pathogenesis of leptospirosis?
A
- Extraellular
11
Q
How does leptosirosis immune avade?
A
- mimics host compliment proteins
- cleavage of compliment proteins
- inactivation of compliment proteins
