(1981) but had the naturally occuring H-antigen d. They were not lysed by any of the phages of the Vi phage typing system. After passage through semi-solid medium containing H-z<jats:sub>66<\/jats:sub> antiserum, H-antigens of 11 of 18 cultures with H-z<jats:sub>66<\/jats:sub> phage changed to H-j and those of 2 others to H-d, while the remaining 5 were immobilized. With cultures in the H-d or H-j phages, change of the H-antigens did not occur when they were cultured in semi-solid medium containing homologous H-antiserum. These phase induction experiments as well as colony examination of original cultures suggest that H-z<jats:sub>66<\/jats:sub> phase is unstable and tends to change of H-antigen to H-d or H-j occured without difficulty probably represented a mixed population of cells in the H-z<jats:sub>66<\/jats:sub> and H-d or H-j phases. Since none of 856 isolates from Japan or fromimported cases of typhoid fever from Southeast Asia other than Indonesia exhibited the H-z<jats:sub>66<\/jats:sub> antigen, it was concluded that the focus of typhois fever caused by <jats:italic>S. typhi<\/jats:italic> in H\u2013z<jats:sub>66<\/jats:sub> phase was probably in Indonesia.<\/jats:p>","DOI":"10.1017\/s0950268800054236","type":"journal-article","created":{"date-parts":[[2009,5,15]],"date-time":"2009-05-15T09:33:27Z","timestamp":1242380007000},"page":"311-314","source":"Crossref","is-referenced-by-count":9,"title":["Occurrence of H-antigen z<sub>66<\/sub> of R phase in cultures of <i>Salmonella<\/i> serovar typhi originated from Indonesia"],"prefix":"10.1017","volume":"101","author":[{"given":"K","family":"Tamura","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R","family":"Sakazaki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S","family":"Kuramochi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A","family":"Nakamura","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2009,5,15]]},"reference":[{"key":"S0950268800054236_ref004","volume-title":"The Bacteriology of Enterobacteriaceae","author":"Kauffmann","year":"1966"},{"key":"S0950268800054236_ref002","first-page":"331","article-title":"An unusual H antigen (z66) in strains of Salmonella typhi","volume":"132","author":"Guin\u00e9e","year":"1981","journal-title":"Annales de Microbiologie (Institut Pasteur)"},{"key":"S0950268800054236_ref001","volume-title":"Identification of Enterobacteriaceae","author":"Edwards","year":"1972"},{"key":"S0950268800054236_ref003","doi-asserted-by":"publisher","DOI":"10.1007\/BF02177415"}],"container-title":["Epidemiology and Infection"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0950268800054236","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,5,20]],"date-time":"2019-05-20T19:10:48Z","timestamp":1558379448000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0950268800054236\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1988,10]]},"references-count":4,"journal-issue":{"issue":"2","published-print":{"date-parts":[[1988,10]]}},"alternative-id":["S0950268800054236"],"URL":"https:\/\/doi.org\/10.1017\/s0950268800054236","relation":{},"ISSN":["0950-2688","1469-4409"],"issn-type":[{"value":"0950-2688","type":"print"},{"value":"1469-4409","type":"electronic"}],"subject":[],"published":{"date-parts":[[1988,10]]}}}
