The antiviral activity of the mononucleosis sera was associated with the IgM antibodies, while the antiviral activity of the \u201cnormal\u201d human sera was associated with the IgG antibodies. It was concluded from these findings that the appearance of antibodies to herpes-type virus in heterophile-positive sera represents a primary immunogenic exposure to this virus, or to a serologically related virus. This conclusion, in turn, suggests that herpes-type virus or a serologically related virus is the etiologic agent of heterophile-positive mononucleosis.<\/jats:p>","DOI":"10.1073\/pnas.68.7.1407","type":"journal-article","created":{"date-parts":[[2006,5,31]],"date-time":"2006-05-31T02:29:54Z","timestamp":1149042594000},"page":"1407-1411","update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":22,"title":["Serologic Evidence that a Herpes-Type Virus is the Etiologic Agent of Heterophile-Positive Infectious Mononucleosis"],"prefix":"10.1073","volume":"68","author":[{"given":"Berge","family":"Hampar","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Konrad C.","family":"Hsu","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Columbia University, New York"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lidia M.","family":"Martos","sequence":"additional","affiliation":[{"name":"Flow Laboratories, Inc., Rockville, Maryland 20852"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John L.","family":"Walker","sequence":"additional","affiliation":[{"name":"Flow Laboratories, Inc., Rockville, Maryland 20852"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"341","published-online":{"date-parts":[[1971,7]]},"container-title":["Proceedings of the National Academy of Sciences"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/pnas.org\/doi\/pdf\/10.1073\/pnas.68.7.1407","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,4,13]],"date-time":"2022-04-13T10:42:57Z","timestamp":1649846577000},"score":1,"resource":{"primary":{"URL":"https:\/\/pnas.org\/doi\/full\/10.1073\/pnas.68.7.1407"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1971,7]]},"references-count":0,"journal-issue":{"issue":"7","published-print":{"date-parts":[[1971,7]]}},"alternative-id":["10.1073\/pnas.68.7.1407"],"URL":"https:\/\/doi.org\/10.1073\/pnas.68.7.1407","relation":{},"ISSN":["0027-8424","1091-6490"],"issn-type":[{"value":"0027-8424","type":"print"},{"value":"1091-6490","type":"electronic"}],"subject":[],"published":{"date-parts":[[1971,7]]},"assertion":[{"value":"1971-07-01","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
