In the present study we demonstrated this antigen directly in the urine from patients with urinary tract infections (UTI) elicited by enterobacteria. Sheep erythrocytes were incubated with UTI urine; this resulted in their coating with ECA, which was studied by means of hemagglutination by anti-ECA serum. Test tube hemagglutination and the more simple slide hemagglutination were employed and with both procedures similar results were obtained. Positive results were observed in 94\u201399% of urine specimens from enterobacterial UTI collected in The Buffalo Children\u2019s Hospital in the 1960s. ECA in urine could also be demonstrated by hemagglutination inhibition. In this test, antibodies in anti-ECA serum were neutralized as a result of incubation of this serum with urine, and agglutination by the antiserum of sheep erythrocytes coated with a standard ECA preparation was prevented or reduced. By means of this latter test, ECA could be demonstrated in 67\u201388% of urine specimens from enterobacterial UTI. The possible diagnostic application of these tests has been discussed.<\/jats:p>","DOI":"10.1159\/000234727","type":"journal-article","created":{"date-parts":[[2009,8,7]],"date-time":"2009-08-07T09:46:18Z","timestamp":1249638378000},"page":"420-426","source":"Crossref","is-referenced-by-count":1,"title":["Detection of Antigens from Gram-Negative Bacilli in Urine of Children with Urinary Tract Infections"],"prefix":"10.1159","author":[{"given":"Dong Soo","family":"Kim","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eugene A.","family":"Gorzynski","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Felix","family":"Milgrom","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,8,5]]},"container-title":["International Archives of Allergy and Applied Immunology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/234727","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000234727","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T10:58:39Z","timestamp":1777633119000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000234727"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,8,5]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000234727","archive":["Portico"],"relation":{},"ISSN":["0020-5915","2571-6662"],"issn-type":[{"value":"0020-5915","type":"print"},{"value":"2571-6662","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,8,5]]}}}
