This was not simply due to cross-infection between the two schools, for two different, unusual strains of <jats:italic>Sh. sonnei<\/jats:italic> were distinguished. One was a novel kanamycin-resistant colicine type 7 strain, and as far as we know this was the first school outbreak due to such a strain to be documented. The other strain was kanamycin-sensitive and of colicine type 0 with a rare specific requirement for aspartic acid. There was some evidence to suggest that the kanamycin-resistant strain was more infective for adults and possibly more pathogenic than the kanamycin-sensitive.<\/jats:p><jats:p>Studies on the transfer of drug resistance and of colicinogeny revealed that the factor determining colicine type 7 was carried on a transmissible plasmid, a new observation. Various drug resistances were also transmissible experimentally, and some were spontaneously unstable. Non-transferable ampicillin-resistance in the colicine type 7 strain and aspartic acid dependence in the colicine type 0 strain enabled all but one of the isolates to be classified into two distinct lines. No common ancestor was found and it was concluded that although occurring together they must have arisen from separate sources.<\/jats:p>","DOI":"10.1017\/s0022172400063166","type":"journal-article","created":{"date-parts":[[2009,10,19]],"date-time":"2009-10-19T13:03:31Z","timestamp":1255957411000},"page":"589-596","update-policy":"http:\/\/dx.doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":5,"title":["An epidemiological study of strains of <i>Shigella sonnei<\/i> from two related outbreaks"],"prefix":"10.1017","volume":"70","author":[{"given":"Mair E.
