[The antigen H:z66 in 1,000 strains of Salmonella typhi from the Antilles, Central America and South America].

Abstract

The research of the flagellar antigen H:z66 of Salmonella typhi was performed in 1,000 strains from the West Indies, Central America and South America. A method based on the immobilization of motile strains in soft agar with immune serum anti-H: d was used to detect strains carrying this flagellar antigen. No strains had antigen H:z66 irrespective to their biovar, phage-type, colicinogeny, drug susceptibility and geographical origin. Future investigations are needed for a better knowledge of the worldwide distribution of Salmonella typhi strains carrying antigen H:z66.
