It may cause toxic shock syndrome, which can be fatal. Here, we report a rare case of a pregnant woman who developed infectious sacroiliitis due to group A streptococcus infection. To the best of our knowledge, this case is the first of its kind to be reported.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Case presentation<\/jats:title>\n                <jats:p>A 32-year-old multiparous Japanese woman presented with fever and right buttock pain at 28\u00a0weeks of gestation. Based on our clinical findings and investigations, she was diagnosed with group A streptococcus bacteremia and infectious sacroiliitis caused by group A streptococcus. A cardiotocography performed to assess the fetal status showed fetal tachycardia. To prevent the patient from progressing to toxic shock syndrome caused by group A streptococcus, we performed an emergency cesarean section. The patient and her infant had a good course after the cesarean section.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>A pregnant woman diagnosed with group A streptococcus infection needs to be monitored closely because a timely decision to deliver the fetus before rapid deterioration to toxic shock syndrome is crucial.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s13256-022-03271-4","type":"journal-article","created":{"date-parts":[[2022,2,11]],"date-time":"2022-02-11T00:02:56Z","timestamp":1644537776000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Infectious sacroiliitis due to group A streptococcus infection during pregnancy: a case report"],"prefix":"10.1186","volume":"16","author":[{"given":"Mikako","family":"Nagashima","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4045-327X","authenticated-orcid":false,"given":"Norikazu","family":"Watanabe","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yosuke","family":"Okui","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mika","family":"Fukase","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kanako","family":"Takahashi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tsuyoshi","family":"Ohta","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seiji","family":"Tsutsumi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuya","family":"Takakubo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michiaki","family":"Takagi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Satoru","family":"Nagase","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2022,2,11]]},"reference":[{"key":"3271_CR1","doi-asserted-by":"publisher","first-page":"5","DOI":"10.1007\/s00404-014-3440-0","volume":"291","author":"J Hasegawa","year":"2015","unstructured":"Hasegawa J, Sekizawa A, Yoshimatsu J, Murakoshi T, Osato K, Ikeda T, et\u00a0al.
