BUNV is transmitted by mosquito vectors of the genera <jats:italic>Culex<\/jats:italic>, <jats:italic>Aedes<\/jats:italic> and <jats:italic>Anopheles<\/jats:italic> and has historically circulated in East Africa, though the transmission has been observed in Argentina. BUNV has been identified as an agent of human and animal disease and has also been misdiagnosed as other agents. BUNV is often thought to be an agent of mild febrile illness in humans, though it can cause abortions in ruminants and neurological disease in horses. Joint pain and gastritis have also been attributed to BUNV. There are limited data concerning the possible spectrum of disease and extent of pathogenesis of BUNV infection, and there are currently no therapeutics or vaccines available. Furthermore, options for animal models for Orthobunyaviruses in general \u2013 of which BUNV is the prototypical member \u2013 are limited. Eight mice deficient in the type I interferon response were infected with BUNV, and all developed overt disease. All mice developed detectable viraemia and clinical signs, including weight loss, hunched posture and lethargy. Three of the eight mice developed severe diseases, including vascular necrosis and necrosis in the liver, lungs, reproductive organs, bone marrow and spleen, as well as haemorrhages (<jats:italic>n<\/jats:italic>=1) and severe diffuse facial oedema (<jats:italic>n<\/jats:italic>=3), reminiscent of the pathology of Schmallenberg and the Arenaviruses Lassa and Lujo viruses. Thus, BUNV infection of IRF3\/7 DKO mice could serve as a BSL-2 model for severe diseases of higher-risk group viruses, which often must be studied at BSL-4. Additionally, our results suggest that BUNV may have the ability to cause severe disease in immunocompromised hosts. Thus, further investigation into the potential spectrum of pathogenesis due to BUNV is important to prioritize for outbreak response, diagnostics and the development of countermeasures.<\/jats:p>","DOI":"10.1099\/jgv.0.002040","type":"journal-article","created":{"date-parts":[[2024,11,6]],"date-time":"2024-11-06T15:16:15Z","timestamp":1730906175000},"source":"Crossref","is-referenced-by-count":0,"title":["Preliminary evidence that Bunyamwera virus causes severe disease characterized by systemic vascular and multiorgan necrosis in an immunocompromised mouse model"],"prefix":"10.1099","volume":"105","author":[{"given":"M.
