MT4 - Diseases caused by E. coli in swine (R) Flashcards
Oedema disease occurs most frequently in calves
F
swine
Oedema disease of weaned piglets is caused by enterotoxigenic E. coli strains
F
Verotoxigenic/shigatoxic E. coli strains (VTEC)
High fever is a typical clinical sign of coli diarrhoea of new-born piglets.
F
NO fever, dehydration, diarhhoea (yellow feaces), depression
Verotoxigenic strains are responsible for oedema disease.
T
E. coli strains that cause coli-diarrhoea of new-born piglets have F17 fimbrial antigens
F
F4, F6, (F5) fimbria
Oedema disease generally occurs 1-2 weeks after weaning.
T
Weaning is a predisposing factor of oedema disease
T
weaning, sudden change in diet, high protein content of the food
Neonatal coli diarrhoea of piglets is seen typically in 1-10-day-old animals
T
Verotoxigenic Escherichia coli strains cause neonatal coli diarrhoea of pigs
F
enterotoxigenic E. coli (ETEC)
Verotoxigenic E.coli strains can cause disease in 2-8-day-old piglets
T
mainly 1-2 weeks
Coli diarrhoea of new-born piglets is caused by fimbriated Escherichia coli strains
T
Coli-diarrhoea of new-born piglets are caused by enteroinvasive E.coli strains
F
enterotoxigenic E. coli (ETEC)
Pigs with neonatal coli diarrhoea have to be treated per os with antibiotics
T
per os antibiotic and rehydration
Enterotoxins are responsible for the clinical signs and lesions of oedema disease
F
Verotoxigenic/shigatoxic E. coli strains (VTEC)
Inflammations of the large intestine is a post mortem lesion of coli diarrhoea of neonatal piglets
F
animals showing clinical signs of oedema disease are recommended to be treated with penicillin:
F
enterotoxigenic Escherichia coli strains are responsible for oedema disease
F
Verotoxigenic/shigatoxic E. coli strains (VTEC)
per os antibiotics are recommended for the treatment of neonatal coli diarrhoea
T
per oral antibiotics + rehydration
There is widespread vaccination for the prevention of oedema disease:
F
in case of coli-diarrhoea of weaned piglets it is advisable to reduce the amount of feed
T
- decreased amount of feed
- increase fibre content
- gadually feed chan
neonatal coli diarrhoea is more frequent in piglets of first farrowing gilts

diarrhoea with yellowish faeces is a characteristic clinical sign of oedema diseases of weaned
piglets:
F
is is carachterisit of: coli.diarrhoea of newborn piglets
Oedema disease is caused by enteropathogenic Escherichia coli strains

Verotoxigenic/shigatoxic E. coli strains (VTEC)
In case of coli diarrhoea of new-born piglets, septicaemia is frequent:
F
Vero-toxins produced by E. coli strains cause diarrhoea in pigs
F
- No fever, no diarrhea
- sudden onset
- oedema of eyelid, nose , ear et
