Rotavirus infection in newborn calves. I. Evaluation trials of certain enzymes in faeces.

The purpose of this work was to investigate the relationship between rotavirus infection, diagnosed in faeces using the serological test, in calves with diarrhoea and the activity of lysozyme, alpha-amylase, lipase and trypsin in the same material. The faeces were taken from 28 sick and 1 healthy animals, aged from 1 to 5 days, for microbiological and enzymatic examination. No correlation was found between lysozyme activity in faeces and rotavirus infection. Similar results were obtained with the other enzymes.
