Sood L R [National Salmonelta and Escherichla Centre, Central Research Institute, Kasauli, India] and Basu S. Geographical distribution and epidemiological incidence of phage-types of Salmonelle weltevreden in India during 19581974. International Journal of Epidemiology 1981, 10: 181185.
Phage-typing of Salmonella weltevreden was carried out with a set of 6 typing phages and the geographical distribution of 946 strains isolated during 19581974 studied. Phage-type 5 was the most predominant type and types 2 and 7 were found exclusively in India. Strains isolated from epidemics and epizootics were studied to assess the epidemiological significance and utillity of the scheme based on the set of six typing phages. Phage-types from various sources in different geographical regions were studied with reference to the incidence in man.
