During the period 29 different phage types were encountered, not including the categories of \u2018untypable strains\u2019, \u2018degraded Vi-strains\u2019 and Vi negative strains. For the period as a whole, the commonest phage types encountered were A (20\u00b79%), E<jats:sub>1<\/jats:sub> (14\u00b78%), D<jats:sub>1<\/jats:sub> (10\u00b73%), degraded Vi positive strains (10\u00b73%), untypable Vi strains (7\u00b73%), C<jats:sub>4<\/jats:sub> (7\u00b71%), D<jats:sub>2<\/jats:sub> (4\u00b74%), E<jats:sub>2<\/jats:sub> (3\u00b79%) and type 25 (2\u00b76%). There were phage types which appeared in the early years of the period and then disappeared (types B<jats:sub>2<\/jats:sub>, D<jats:sub>9<\/jats:sub> and D<jats:sub>1-N<\/jats:sub>). Others only made their appearance in recent years (K<jats:sub>1<\/jats:sub> and 53). Notable differences were also seen in the predilection of some phage types for certain geographical areas.<\/jats:p>","DOI":"10.1017\/s0022172400063889","type":"journal-article","created":{"date-parts":[[2009,10,19]],"date-time":"2009-10-19T09:03:05Z","timestamp":1255942985000},"page":"91-97","update-policy":"http:\/\/dx.doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":8,"title":["Phage types of <i>Salmonella typhi<\/i> isolated in Malaysia over the 10-year period 1970\u20131979"],"prefix":"10.1017","volume":"90","author":[{"given":"M.","family":"Jegathesan","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2009,10,19]]},"reference":[{"key":"S0022172400063889_ref002","first-page":"448","article-title":"Demonstration of types of B. typhosus by menus of preparation of typo II Vi phage: principles and techniques","volume":"29","author":"Craigie","year":"1938","journal-title":"Canadian Public Health Journal"},{"key":"S0022172400063889_ref001","doi-asserted-by":"publisher","DOI":"10.1136\/jcp.9.2.94"},{"key":"S0022172400063889_ref010","first-page":"171","article-title":"Prevalence of Salmonella phnge types in Madurae","volume":"71","author":"Uma","year":"1980","journal-title":"Indian Journal of Medical Research"},{"key":"S0022172400063889_ref003","doi-asserted-by":"publisher","DOI":"10.1017\/S0022172400052797"},{"key":"S0022172400063889_ref004","unstructured":"Fukumi H.
