Define zoonosis

Dsieases transmitted naturally between vertebrate animals and humans


Define carrier status

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


Define reservoir

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


Define colonised host

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


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)


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


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


What are the implications of MRSA in smallies practice ?

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


Give 2 examples of exotic pet linked disease

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


Give 3 responsibilities of the vet

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


How long can different bacteria survive on dry surfaces?

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


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


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


Give examples of non zoonotic parasites

- human head louse
- guinae pig louse
