Incubation at raised temperature or enrichment media, combined with secondary enrichment in Rappaport's medium, for the isolation of salmonellas from sewage.
Two FMDV strains which had been previously differentiated by complement-fixation were compared by guinea-pig protection test, kinetic neutralization and micro-neutralization tests. It was found that these tests, which have not been previously applied by the methods described, were all capable of FMDV STRAIN DIFFERENTIATION. Similar differences were found by all methods, which suggests that comparisons made by cross-CF, cross-neutr-alization or cross-protection involve measurement of the same antigen/antibody interactions.
