Epidemiological investigations on vi negative strains of salmonella typhi isolated from bangalore and kurnool in southern india

Epidemiological investigations on vi negative strains of salmonella typhi isolated from bangalore and kurnool in southern india

Three batches of S. typhi strains subjected to a complementary phage typing scheme. The scheme was useful for the identification of Vi-phage types of Vi-negative strains isolated at Bangalore and Kurnool. A Vi-negative strain, identified as phage type JI by the complementary phage typing scheme, was found to be connected to an outbreak [in humans] caused by the same phage type. The nonmotile, Vi-negative strains from Kurnool, provisionally identified as S. typhi, were typed by the scheme as subtype Chamblee, phage type A of S. typhi. The epidemiological correlation between Vi-negative strains and the Vi-phage types of S. typhi was discussed.
