Abstract
SUMMARY: An index of discrimination was used to assess the discriminatory power of biotyping for salmonellas of selected serotypes. Three collections of phage-typed strains ofSalmonella typhimuriumandSalmonella paratyphiB, previously tested for biotype, were examined. The results established that the discrimination index was high when full biotyping alone was used for differentiation of strains from international series. When biotyping was combined with phage typing, the discrimination achieved was greater than for either method used alone. These findings confirm that biotyping affords excellent discrimination of strains ofS. typhimuriumandS. paratyphiB and indicate that the results obtained from biotyping can be interpreted with confidence.This publication has 19 references indexed in Scilit:
