Flashcards in Non-Food Zoonoses - Companion Deck (14):
1

Define zoonosis

Dsieases transmitted naturally between vertebrate animals and humans

2

Define carrier status

Pathogens isolated from animal/human without causing clinical sings of disease in the host

3

Define reservoir

spread of a n orgnaism within the reservoir host to maintain the pathogen indefintiely

4

Define colonised host

No clinical signs on host but microbes can multiply on the host (longitudinal sampling required to prive this)

5

Give examples of zoonoses in companion animal practice

- rabies
- salmonellosis
- brucellosis
- multi resistant bacteria (MRSA, TB)
- worms
- pasterellosis
- toxaplasmosis
- leptospriosis
- psittacosis
- fleas
- cheyletiellosis
- sarcoptic mange (fox mange)
- dernatophytosis (rinworm)

6

Which drugs are clinically relevant multi-drug resistant pathogens in human medicine?

E - enterococcus feacium
S - S aureus and s intermedius
K - Klebsiella pnumonia
A - Actintoobacter baumannii (+ other spp)
P - Psudomonas aeruginosa
E - Enterbacter spp

7

Which two forms of methicillin-resistant staphlococci exist? Which specific drugs are they resistnet to?

> MRSA (s. aureus)
- human hospital, community and livestock associated
- broad B-lactam and fluoroquinolone resistnance
- reverse zoonotic transmission (spill over into pet population)
> MRSP (pseudintermedius)
- dog adapted
- vet nosocomial pathogen
- highly drug resistant

8

What are the implications of MRSA in smallies practice ?

- most infections can be treated successfully
- better adapted to humans so ^ risk of human spread

9

Give 2 examples of exotic pet linked disease

- Salmonella in reptiles (3-5% of all salmonellosis in USA)
- Fish tank granuloma mycobacterium marium

10

Give 3 responsibilities of the vet

1. early suspicion and correct diagnosis (lab tests)
2. Client communication
3. prevention of spread

11

How long can different bacteria survive on dry surfaces?

- G+ = months
- G- = months
- Pseudomonas aeroguinosa 1 month
- Spor forming = months
- Staph > 12 months

12

What is the protocol for isolation?

Traffic-light system
- red: must be isolated unless unstable
- amber: barrier nurse, await virology/microbiology
- green: no isolation needed

13

What are the risk factors for multi-drug resistence?

- age
- disease and severity of illness
- inter-institutional transfer
- prolonged hosptialisation
- GI sx or transplant
- invasive devices eg. central venous catheters
- antimicrobial

14

Give examples of non zoonotic parasites

- human head louse
- guinae pig louse
