ecoli hardocre Flashcards
faeces of asymptomatic cattle can be the source of infection with zoonotic Escherichia coli
T
E. coli septicemia is caused by verotoxigenic strains
F
Because both Oedema disease and calf dysentery do not have septicaemia
SEPEC strains cause septicaemia
Fimbria is the virulence factor of enteropathogenic E. coli strains
F
Enteropathogenic E. coli strains mainly damage the villi
T
ETEC no villi damage
EPEC damage
EHEC damage
Verotoxigenic Escherichia coli strains can cause disease in pigs
Toedema disease of swinesometimes coli diarrhoea of weaned piglets
Enterotoxin cause enteritis in the large intestine
F
E. coli O157:H7 strains can cause haemorrhagic enteritis in cattle
Fno inflammation ever
Meningitis can be seen in coli-septicaemia of calves
T
Meningitis and polyarthritis
Enteritis in the large intestine is a typical post mortem sign of coli-diarrhoea of calves
F
Coli septicaemia of calves can be diagnosed by measuring antibodies
F
Transport is the most important predisposing factor in coli-diarrhoea
Fage and end of winter
Coli-septicaemia is seen in day-old calves
T
Pneumonia is an important clinical sign of coli-septicaemia in calves
F
E. coli can cause bloody diarrhoea in calves
F
Yellow stinky in case of coli diarrhoea and chronic in calf dysentery.
Verotoxigenic E. coli strains are present in the gut of cattle without clinical signs
Tcows often subclinical carriers
Pigs with neonatal coli diarrhoea have to be treated per os with antibiotics
T
diarrhoea with yellowish faeces is a characteristic clinical sign of oedema diseases of weaned piglets
FNo fever no diarrhoea sudden death
Mainly viral infections predispose weaned piglets to coli-diarrhoea
Fmainly the overeating diet and weaning changes
Coli-diarrhoea of weaned piglets is generally prevented by vaccinating sows
T protected for small amount of time
Oedema disease is seen mainly in large scale farms with poor hygiene
FSmall farms mainlyDiarrhoea in large scale farms
Insufficient colostrum is an important predisposing factor for oedema disease
F
en after weaning anw
weaning and overreting
Septicaemic escherichia coli strains are responsible for E. Coli diseases of poultry
FAvian Pathogenic
Invasive Escherichia coli strains are responsible for E. coli diseases of poultry
T
E. coli strains cause generalized infection in day-old chicken
F in adults septicaemia
E. coli can cause septicaemia in day-old chicken
Fin growers
Isolation of Escherichia coli from the faeces confirms diagnosis of coli septicaemia of poultry
Ffrom bone marrow
Poultry E. coli is caused by enteroinvasive E. coli
F
APEC
Coli-diarrhoea of rabbits is typically seen in suckling animals
F
1-2 weeks after weaning like in the case of coli diarrhoea of weaned piglets and oedema disease
Verotoxigenic Escherichia coli strains cause coli-diarrhoea of rabbits
F
Enterotoxigenic E. coli strains are the causative agents of E. coli diarrhoea in rabbits
F
There is widespread vaccination in order to prevent E. coli diarrhea in rabbits
F
Coli diarrhoea of rabbits is caused by enteropathogenic E. coli strains
T
Coli diarrhoea of rabbits is mainly seen in the first week of life
F
Coli diarrhoea is prevented by widespread vaccination of the mothers
F
Insufficient amount of milk predisposes rabbits to coli-diarrhoea
F
Isolation of Escherichia coli from the faeces of rabbits with diarrhoea confirms coli- diarrhoea
F
From the gut and messenterial LN
E. coli is not a normal inhabitant of the gut flora in rabbits
