Forebrain organoids and newborn mice show an Oropouche infection
A Nature Communications paper reports that historical and circulating Oropouche strains reach neurons in human forebrain organoids at every stage of differentiation. Set against Zika virus, neuroinfection runs higher in the organoids and also in neonatal mice. The paper says clinics have tied recent strains to congenital infection. It does not treat the organoid and mouse findings as a measure of disease in human pregnancy. News pages found for other Oropouche organoid experiments belong to different papers.
