Categorized by disease, there were 14 cases of colitis, 9 cases \n\nof liver abscess, 4 cases of \n\ncolitis with liver abscess, and 1 case of liver abscess with brain \n\nabscess. Patients consisted of 26 \n\nJapanese males, 0 Japanese females, 1 non-Japanese male and 1 non-Japanese\n \n\nfemale. The \n\nmean age of colitis patients and liver abscess patients was 55\u00b74\n \n\nyears old and 41\u00b73 years old, \n\nrespectively. The presumed place of contraction was Japan in 64% of \n\nthe patients. Forty-eight \n\npercent of male patients indicated that they engaged in homosexual or \n\nbisexual practices, and \n\n36% of male patients who denied such sexual practices or did not answer\n \n\nthe question had no \n\nhistory of marriage. Positive rate of serum titre for <jats:italic>Treponema \n\npallidum<\/jats:italic> hemagglutination test \n\n(TPHA) and human immunodeficiency virus antibody was 42\u00b79% and 0%,\n \n\nrespectively. Sixty-seven percent of TPHA-positive patients indicated that\n \n\nthey engaged in male homosexual or \n\nbisexual practices. Zymodeme patterns of <jats:italic>E. histolytica<\/jats:italic> isolated\n \n\nfrom 4 colitis patients were \n\nXIV in 1 case and II in 3 cases. Symptomatic amebiasis in the \n\neast-southeast area of Tokyo is a \n\ndisease which predominantly afflicts males, especially those in their \n\nmiddle age, and most \n\npatients contract the disease in Japan. The high rates of patients who\n \n\nengaged in male \n\nhomosexual or bisexual practices and the high rates of patients with \n\npositive TPHA suggest \n\nthat amebiasis is likely to be sexually transmitted disease in homosexual\n and \n\nbisexual men in \n\nthe east-southeast area of Tokyo, and zymodeme II may be the predominant\n type in \n\nsymptomatic amebic colitis in this area.<\/jats:p>","DOI":"10.1017\/s0950268897008236","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T09:23:42Z","timestamp":1027761822000},"page":"363-367","source":"Crossref","is-referenced-by-count":27,"title":["Present characteristics of symptomatic amebiasis due to \n\n<i>Entamoeba histolytica<\/i> in the east-southeast area of Tokyo"],"prefix":"10.1017","volume":"119","author":[{"given":"K.","family":"OHNISHI","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"MURATA","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[1997,12,1]]},"container-title":["Epidemiology and Infection"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0950268897008236","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,5,11]],"date-time":"2019-05-11T15:45:53Z","timestamp":1557589553000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0950268897008236\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1997,12]]},"references-count":0,"journal-issue":{"issue":"3","published-print":{"date-parts":[[1997,12]]}},"alternative-id":["S0950268897008236"],"URL":"https:\/\/doi.org\/10.1017\/s0950268897008236","relation":{},"ISSN":["0950-2688","1469-4409"],"issn-type":[{"value":"0950-2688","type":"print"},{"value":"1469-4409","type":"electronic"}],"subject":[],"published":{"date-parts":[[1997,12]]}}}
