“…Thus this phage-typing scheme based on host range of temperate phages could identify all but one group of epidemiologically related strains and is, therefore, an improvement over the phage-typing scheme developed by Garg and Singh (1973) who could establish epidemiological relationship in only 2 out of the 245 cultures tested by them. Moreover, they employed a mixed culture technique using S. weltevreden strain No.…”

Nine hundred and forty-six strains of Salmonella weltevreden isolated in different states of India during 1958-1974 and 124 strains from Australia, Burma, Holland, Hong Kong, New Zealand, Papua New Guinea, the Philippines, Thailand, the United States and Vietnam during 1953-1971 were phage-typed according to the phage-typing scheme described in the first part of this paper (Sood and Basu, 1977). The epidemiological incidence and geographical distribution of phage-types of Salmonella weltevreden were studied. All the phage-types were present in India, the predominant phage-types being b, d and i. Phage-type g was isolated exclusively from India. All the 14 strains from Hawaii belonged to phage-type i. Phage-type h was the most predominant phage-type in Vietnam. The 15 strains isolated from Papua New Guinea in 1965, which were supposed to have originated from a single source, belonged to 3 phage-types. Except these cultures all the available epidemiologically related strains were of uniform phage-types - a finding which establishes the epidemiological validity of the scheme.

All of the 1070 strains of Salmonella weltevreden tested were lysogenic, temperate phage being demonstrable in 83.9% of the strains in broth culture, 6.4% in mixed culture and the remaining 9.7% after induction by UV-irradiation and MC treatment. A phage-typing scheme for Salmonella weltevreden based on the host range of temperate phages was developed. The strains could be classified into eight groups by means of the host range of their temperate phages on six indicator strains and a ninth group, the symbiotic phages of which failed to lyse any of the indicator strains.
