The goal of the present study was to investigate how genetic variations and sex differences among four commonly used mouse strains contribute to variation in severity, manifestations, and outcomes of NSTIs. DBA\/2J mice were more susceptible to NSTIs than C57BL\/6J, BALB\/c, and CD-1 mice, as exhibited by significantly greater bacteremia, excessive dissemination to the spleen, and significantly higher mortality. Differences in the sex of the mice also contributed to differences in disease severity and outcomes: DBA\/2J female mice were relatively resistant compared to their male counterparts. However, DBA\/2J mice exhibited minimal weight loss and developed smaller lesions than did the aforementioned strains. Moreover, at 48 h after infection, compared with C57BL\/6J mice, DBA\/2J mice had increased bacteremia, excessive dissemination to the spleen, and excessive concentrations of inflammatory cytokines and chemokines. These results indicate that variations in the host genetic context as well as sex play a dominant role in determining the severity of and susceptibility to GAS NSTIs.\n          <\/jats:p>","DOI":"10.1128\/iai.01191-15","type":"journal-article","created":{"date-parts":[[2015,11,17]],"date-time":"2015-11-17T02:33:26Z","timestamp":1447727606000},"page":"416-424","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":14,"title":["Host Genetic Variations and Sex Differences Potentiate Predisposition, Severity, and Outcomes of Group A Streptococcus-Mediated Necrotizing Soft Tissue Infections"],"prefix":"10.1128","volume":"84","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4895-2495","authenticated-orcid":false,"given":"Karthickeyan","family":"Chella Krishnan","sequence":"first","affiliation":[{"name":"Department of Molecular Genetics, Biochemistry and Microbiology, College of Medicine, University of Cincinnati, Cincinnati, Ohio, USA"},{"name":"Department of Basic Biomedical Sciences, School of Medicine and Health Sciences, University of North Dakota, Grand Forks, North Dakota, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Santhosh","family":"Mukundan","sequence":"additional","affiliation":[{"name":"Department of Basic Biomedical Sciences, School of Medicine and Health Sciences, University of North Dakota, Grand Forks, North Dakota, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeyashree","family":"Alagarsamy","sequence":"additional","affiliation":[{"name":"Department of Basic Biomedical Sciences, School of Medicine and Health Sciences, University of North Dakota, Grand Forks, North Dakota, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Donna","family":"Laturnus","sequence":"additional","affiliation":[{"name":"Department of Basic Biomedical Sciences, School of Medicine and Health Sciences, University of North Dakota, Grand Forks, North Dakota, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Malak","family":"Kotb","sequence":"additional","affiliation":[{"name":"Department of Basic Biomedical Sciences, School of Medicine and Health Sciences, University of North Dakota, Grand Forks, North Dakota, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"235","reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM198707163170305"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/0140-6736(90)92777-F"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1093\/clinids\/14.1.2"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1093\/clind\/16.6.792"},{"key":"e_1_3_3_6_2","first-page":"93","article-title":"The reemergence of severe group A streptococcal disease: an evolutionary perspective","volume":"7","author":"Low DE","year":"1997","unstructured":"Low DE, Schwartz B, McGeer A. 1997.
