[Typhoid fever in Vietnam. I. Bacteriological study (607 Salmonella strains isolated from 1961 to 1975 at the Grall Hospital of Saigon)].

From 1961 to 1975, researches on salmonellosis have been carried out in Hospital Grall, in Saigon, mainly during two periods (1961-1964, then 1971-1975). 607 strains of Salmonella have been isolated for these 15 years (558 S. typhi and 49 Salmonella, among several other serotypes).
