The subclasses of<jats:italic>C. burnetii<\/jats:italic>-specific antibodies were determined by immunofluorescence in 20 patients with acute Q fever and 20 patients with chronic Q fever. Although immunoglobulin G1 (IgG1) and IgG3 antibodies were found in acute and chronic Q fever, neither IgG2 nor IgG4 was detected. The detection of IgG1 and IgG3 antibodies was not due to an increase of the IgG1 and IgG3 subclasses. Moreover, IgG1 and IgG3 antibodies were not correlated, suggesting that they may play different roles in Q fever.<\/jats:p>","DOI":"10.1128\/cdli.5.6.814-816.1998","type":"journal-article","created":{"date-parts":[[2019,12,31]],"date-time":"2019-12-31T19:21:37Z","timestamp":1577820097000},"page":"814-816","update-policy":"http:\/\/dx.doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":8,"title":["Increases in the Levels of<i>Coxiella burnetii<\/i>-Specific Immunoglobulin G1 and G3 Antibodies in Acute Q Fever and Chronic Q Fever"],"prefix":"10.1128","volume":"5","author":[{"given":"Christian","family":"Capo","sequence":"first","affiliation":[{"name":"<!--label omitted: 1-->Unite\u0301 des Rickettsies, Universite\u0301de la Me\u0301diterrane\u0301e, CNRS UPRESA 6020, Faculte\u0301 de Me\u0301decine, 13385 Marseille Cedex 05, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ioana","family":"Iorgulescu","sequence":"additional","affiliation":[{"name":"<!--label omitted: 1-->Unite\u0301 des Rickettsies, Universite\u0301de la Me\u0301diterrane\u0301e, CNRS UPRESA 6020, Faculte\u0301 de Me\u0301decine, 13385 Marseille Cedex 05, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maryse","family":"Mutillod","sequence":"additional","affiliation":[{"name":"<!--label omitted: 1-->Unite\u0301 des Rickettsies, Universite\u0301de la Me\u0301diterrane\u0301e, CNRS UPRESA 6020, Faculte\u0301 de Me\u0301decine, 13385 Marseille Cedex 05, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jean-Louis","family":"Mege","sequence":"additional","affiliation":[{"name":"<!--label omitted: 1-->Unite\u0301 des Rickettsies, Universite\u0301de la Me\u0301diterrane\u0301e, CNRS UPRESA 6020, Faculte\u0301 de Me\u0301decine, 13385 Marseille Cedex 05, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Didier","family":"Raoult","sequence":"additional","affiliation":[{"name":"<!--label omitted: 1-->Unite\u0301 des Rickettsies, Universite\u0301de la Me\u0301diterrane\u0301e, CNRS UPRESA 6020, Faculte\u0301 de Me\u0301decine, 13385 Marseille Cedex 05, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"235","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1128\/mr.47.2.127-149.1983"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1749-6632.1990.tb42220.x"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF01590941"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1136\/jcp.38.7.743"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/0008-8749(92)90073-X"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1128\/jcm.22.4.484-487.1985"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1093\/infdis\/148.3.477"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1128\/JCM.36.7.1823-1834.1998"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1128\/jcm.30.8.1958-1967.1992"},{"key":"e_1_3_2_11_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1749-6632.1990.tb42203.x"},{"key":"e_1_3_2_12_2","first-page":"18","article-title":"IgG1 subclass preference of selected, naturally occurring antipolysaccharide antibodies.","volume":"23","author":"Hammarstrom L.","year":"1988","unstructured":"Hammarstrom L.
