Alexa, P.; Salajka, E.; Salajkova, Z.; Machova, A., 1995: Combined parenteral and oral immunization against diarrhoea in weaned piglets caused by enterotoxigenic strains of Escherichia coli. Veterinarni Medicina 40(12): 365-370
On the day of weaning at 35 days of age, 6 piglets were injected i.m. with a formalin-inactivated enterotoxigenic Escherichia coli (ETEC) strain 8943. The next day they were given orally a live culture of the non-toxic E. coli strain 8914. A week later they were challenged orally with a live culture of the ETEC strain 8943; 4 non-immunized controls were also challenged.
