Endotoxins have an important role in the pathogenesis of coli-septicaemia of calves
T
Coli-diarrhoea of new-born calves can be prevented by vaccinating the pregnant cows
T
E. coli strains that cause coli-diarrhoea of new-born piglets have F17 fimbrial antigens
F- calf
Coli septicaemia of calves can be diagnosed by isolation of E. coli from the small intestine
F
parenchymal organs, blood
calves are vaccinated with inactivated vaccines in order to prevent coli septicaemia
F
no vaccination
E. coli O157:H7 strains can cause haemorrhagic enteritis in cattle:
F
calves not cattle
hypo-gammaglobulinemia can predispose cattle to coli septicaemia:
T
- hypogammaglobulinaemia
- umbilical (navel) infection
peroral antibacterial treatment of calves is advisable for treatment of coli-septicaemic
calves:
F
parenteral antibiotics ( generally no tiem)
coli diarrhoea of new born calves is caused by enterotoxigenic Escherichia coli strains
T
Coli septicaemia of calves is seen most frequently after weaning
F
first week of life
