T-A-but not adding up w prev similiar pqs (calf)
think ab maybe just for litter mate
per oral antibiotics + rehydration

T
toxin absorbed in bloodstream
damage endithelial cell fo small arteries

NO fever, NO diarrhea, oedema in eyelid, nose, ear etc..
Clinical cases of oedema disease can be successfully treated with parenteral penicillin
injections.
F
Oedema disease typically occurs in 2-3-week-old piglets
F
1-2 weeks after waning in rapidly growing pigs
In the case of oedema disease, the permeability of the blood vessels is increased
T
increase permeability + perivascular edema
Severe diarrhoea is a frequent sign of oedema disease.
F
NO fever, NO diarrhea, oedema in eyelid, nose, ear etc..
Oedema disease is caused by verotoxigenic Escherichia coli strains
T
Oedema disease can occur at any age
F
1-2 weeks
Vaccination of the sows is widely used in order to prevent oedema disease.
F
Enterotoxigenic Escherichia coli strains are the main causative agents of coli-diarrhoea in
weaned piglets
T
Mainly viral infections predispose weaned piglets to coli-diarrhoea
T-A
Oedema formation is the main clinical sign of coli-diarrhoea of weaned piglets.
F
Oedema disease
Increasing the fiber content of the feed can reduce the losses of coli-diarrhoea in weaned
piglets
T
E. coli diarrhoea in swine occurs in sows in their first pregnancy
F
E. coli diarrhoea in swine occurs in large scale farms worldwide
T
The faeces of weaned piglets with coli-diarrhoea has a strong smell
