Camphylobacter, vibrio, lawsonia, actinobacillus Flashcards
1
Q
campylobacter info
A
- anaerobic
- gram negative rods
2
Q
species of campylobacter in animals and humans (3)
A
- c fetus sub species venerealis
- c fetus sub species fetus
- c jejuni
3
Q
campylobacter fetus
A
- sub species fetus –> intestines, causes late abortions in sheep/cattle, oral transmission
- sub species venerealis –> bovine rep tract, early abortions, infertility, venereal transmission
4
Q
campylobacter fetus sub sp venerealis
A
- bovine reproductive tract (males and females)
- reservoir is prepuceal crypts of infected bull and vagina of carrier animals
- infertility, inflammation, early abortions (failure of implantation)
- venereal transmission
- older bulls more susceptible
5
Q
is campylobacter fetus sub sp venerialis associated with human infection
A
no
6
Q
campylobacter fetus sub sp fetus
A
- intestines of cattle, sheep, goats
- transmission by ingestion
- late abortions (placental inflammation)
7
Q
is campylobacter fetus sub sp fetus associated with human infection
A
yes
8
Q
which causes more problems - c fetus sub sp venerealis or fetus
A
sub sp venerealis
9
Q
campylobacter jejuni
A
- avian species, wild and domestic animals (cats, dogs, cattle) as well –> diarrhea
- enteritis in humans
- domestic animals may infect humans
- # 1 foodborne pathogen in many countries
10
Q
campylobacter transmission to humans
A
- contaminated meat
- contaminated water, raw milk
- contact with infected animals
11
Q
vibrio info
A
- gram negative rods
- facultative anaerobe
- sea and fresh water
- seldom a pathogen of domestic animals
- cholera –> humans
12
Q
lawsonella intracellularis info
A
- obligate intracellular bacteria
- broad host range
- grows inside intestinal epithelial cells
- proliferative enteritis in pigs (diarrhea, thickened intestinal folds)
- sometimes in horses, dogs
13
Q
actinobacillus info
A
- mainly pathogens of farm animals
- commensals of mucus membrane (upper respiratory tract, oral cavity)
- gram negative short rods
- facultative anaerobe
- infections usually involve soft tissue
- can’t survive long in the environment
14
Q
actinobacillis species
A
- lignieresii (cattle –> tongue)
- equuli (horses –> arthritis, sepsis)
- suis (pigs –> pneumonia)
- pleuropneumoniae (pigs –> pleuropneumonia)
15
Q
a lignieresii
A
- primarily seen in cattle
- normal flora of buccal membranees and upper GI tract
- lesions of soft tissue of face and jaw –> wooden tongue
- from wound that lets bacteria in
