[Studies on diarrhea of young calves. 1. Quantitative analysis of the gastrointestinal flora in clinically healthy calves and in calves with diarrhea].

Quantitative composition of gastro-intestinal-flora was determined in 23 clinically healthy calves and the course of germ spreading was followed up. In comparison with these healthy animals in 25 diarrhoea affected calves at the age of 4 to 17 days there could be observed signigicant differences only in few parts of the gastro-intestinal-tract concerning the quantitative composition of germ flora. Only in 3 animals enterotoxin producing E coli strains could be detected.
