Tuberculosis (TB) patients produce antibodies against some such proteins, but it is not clear whether these responses correlate with disease. Clinical groups with different mycobacterium exposure were studied for their seroreactivity to PE-PGRS17 and PE-PGRS62 proteins and their respective PE domains. There were minimal antibody responses against both PE domains and full-length PE-PGRS17, even in patients with active TB. However, patients with active and latent TB showed significantly higher PE-PGRS62-specific immunoglobulin G antibody responses than treated TB patients and mycobacterium-reactive TB contacts without latent infection. Latently infected persons had high anti-PE-PGRS62 responses but low responses to the 38-kDa antigen commonly used for TB serology, while treated TB cases showed the opposite response. Thus, patterns of seroreactivity to PE-PGRS62 correlate with clinical status and are associated with latent TB infection.\n                  <\/jats:p>","DOI":"10.1128\/iai.01175-08","type":"journal-article","created":{"date-parts":[[2009,6,1]],"date-time":"2009-06-01T20:58:56Z","timestamp":1243889936000},"page":"3337-3343","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":31,"title":["Strong Antibody Responses to\n                    <i>Mycobacterium tuberculosis<\/i>\n                    PE-PGRS62 Protein Are Associated with Latent and Active Tuberculosis"],"prefix":"10.1128","volume":"77","author":[{"given":"Kah Wee","family":"Koh","sequence":"first","affiliation":[{"name":"Department of Microbiology"},{"name":"Immunology Programme, Yong Loo Lin School of Medicine, National University of Singapore, Singapore 117597, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shu E","family":"Soh","sequence":"additional","affiliation":[{"name":"Department of Microbiology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Geok Teng","family":"Seah","sequence":"additional","affiliation":[{"name":"Department of Microbiology"},{"name":"Immunology Programme, Yong Loo Lin School of Medicine, National University of Singapore, Singapore 117597, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1128\/IAI.68.6.3314-3321.2000"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1099\/00221287-146-12-3205"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0966-842X(02)02335-1"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.vaccine.2007.07.026"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1164\/ajrccm.156.3.9607122"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0014-5793(99)00536-0"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1038\/31159"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1128\/IAI.73.10.6846-6851.2005"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1128\/IAI.69.9.5606-5611.2001"},{"key":"e_1_3_2_11_2","doi-asserted-by":"publisher","DOI":"10.1099\/00221287-145-12-3487"},{"key":"e_1_3_2_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0378-1119(03)00751-0"},{"key":"e_1_3_2_13_2","first-page":"778","volume":"2","year":"1998","unstructured":"Foulds, J., and R.
