The sero-fermentative-phage types of Salmonella weltevreden.
A biotyping scheme has been described which is based on the biochemical behaviour of S. weltevreden strains towards 5 substrates (sorbitol, dextrin, malonate, rhamnose, starch). The 228 S. weltevreden strains examined were grouped into 25 of the 32 theoretical biotypes. Frequently occurring biotypes were: biotype 10 (16.2%), biotype 5 (13.4%) and biotype 11 (11.4%). No substantial correlation could be established between biotypes and source or geographic distribution of S. weltevreden. Sero-fermentative-phage types were computed for 145 strains, phage-types of which has been described earlier and five predominant sero-fermentative-phage types emerged. The sero-fermentative-phage type 3, 10:r:z6;5;1 (serotype = 3, 10:r:z6; biotype = 5; phagetype =1) occurred most commonly with a frequency of 10.3%. The strains belonging to this pattern were from lizard, guinea-pig and humans in India, Netherlands and United States of America.
