MT4 - E. COLI GENERAL (R) Flashcards
Lack of colostrum is an important predisposing factor in diseases in young animals caused by E. coli.
T
No colostral immunity
poor hygiene
overcrowding
stress
Certain verotoxigenic Escherichia coli strains can be zoonotic.
T
through consumption of food or water, or contact with infected animals
Enterotoxigenic Escherichia coli strains are responsible for oedema disease
F
diarrhea and other gastrointestinal illnesses
oedema disease: (STEC) –> verotoxin or Shiga toxin
Detection of virulence factors of E.Coli is important in the diagnostics diseases caused by E.coli.
T
E. coli can cause haemorrhagic enteritis of humans
T
faeces of asymptomatic cattle can be the source of infection with zoonotic Escherichia coli:
T
Per os antibiotics are recommended for the treatment of neonatal coli diarrhoea of calves
F- changed- can be used but not rec-A
for enteric diseases
E. coli septicemia is caused by verotoxigenic strains
F-A
Fimbria can be virulence factors of E. coli strains
T
fimbra, capsule, LT, ST, verotoxins
LT toxin can be virulence factor of some E. coli strains.
T
fimbra, capsule, LT, ST, verotoxins
Enterotoxigenic E. coli strains cause diarrhoea in neonatal animals
T
instinal / diarrhegenic
The enterotoxigenic E. coli strains cause neonatal diarrhoea in calves and piglets
T
The enterotoxins of E. coli inhibit the protein synthesis.
F
verotoxins inhibit protein synthesis !
The enterotoxigenic E. coli strains have fimbria as adhesins
T
**adhesins: **Fimbra, outer membrane proteins, fibronectine receptors
The verotoxigenic E. coli strains cause septicaemia of calves.
F-A
Endotoxins are the virulence factors of E. coli causing septicaemia
T
LPS
Fimbria is the virulence factor of enterotoxic E. coli strains
T
Verotoxins are the virulence factors of enterotoxic E. coli strains.
F
E. coli (VTEC) or Shiga toxin-producing E. coli (STEC).
Fimbria is the virulence factor of enteropathogenic E. coli strains.
F -its intimin
Enteropathogenic E. coli strains mainly damage the villi
T
E. coli strains always cause generalized infections in animals.
F
Enterotoxins of E. coli cause severe inflammation in the small intestines
F
primarily affect the intestinal epithelial cells, leading to increased secretion of fluids and electrolytes into the intestinal lumen, resulting in watery diarrhea.
Enteropathogenic Escherichia coli strains cause neonatal diarrhoea in calves and piglets
F
In piglets, rabbits, dog and cats
Enteropathogenic Escherichia coli strains damage the microvilli.
