The most common types encountered in this international study were A and E1 (= E1 a), as has been previously observed. There was, however, a wide range of types, many of which are characteristic of particular geographical zones. The occurrence of such types out of their habitual context indicates their \u2018exotic\u2019 origin, providing a useful clue to their probable source.<\/jats:p><jats:p>Plasmid-mediated chloramphenicol resistance appeared in epidemic typhoid fever for the first time during this period.
