RESUMEN
A prospective, controlled-blind field trial was conducted to evaluate the efficacy and safety of paromomycin sulphate, given for 10 days from birth, in preventing natural cryptosporidiosis in calves. In the untreated control group, oocyst shedding and diarrhoea followed the pattern that had occurred on the farm before the trial, consistent with a perinatal infection, whereas in the treated group, the prepatent period was significantly longer than in the control group (P < 0.01) and oocyst shedding and diarrhoea started only after the drug was withdrawn. However, the regimen did not reduce the incidence of disease in the treated group.

The new and convenient method for the separation, isolation and characterization of the N-ciano-N'-methyl-N"-(2-/(5-methylimidazol-4-yl)methylthio/ethyl) guanidine and its biotransformation and degradation products was developed. Mass spectra obtained with the FAB (Fast Atom Bombardment) method are described. This method proved to be very successful for the analysis and characterization of studied compounds.
