We established previously that the high carriage rates of NCHi in these infants result from concurrent and successive colonization with multiple strains, with sequential elimination of dominant strains. Nonencapsulated Haemophilus influenzae (NCHi) colonization of the nasopharynx initially occurs within weeks of birth, persists throughout infancy and most of childhood, and contributes to otitis media. more Aboriginal infants in the Northern Territory of Australia experience recurrent otitis media from an early age. Indeed, it is much more plausible that radiation would mediate its mutationa.Īboriginal infants in the Northern Territory of Australia experience recurrent otitis media from. ![]() However, the exoneration of SNV as mediators of transgenerational radiation effects does not show that such effects do not exist. These negative results were consistent with earlier studies in humans3,4 and mice5.The DNMs detected were predominantly single nucleotide variants (SNV), which did not increase in frequency with estimated parental radiation doses. Animal experiments suggest that de novo gene mutations (DNM) occur with a doubling dose of about one Gy.1 To address this question in humans, Yeager and colleagues2 used whole genome sequencing (WGS) to study DNM in children of parents exposed to Chernobyl radiation before conception. more We have long wondered whether ionizing radiation to parents, before conception, can cause gene mutations leading to adverse effects in the next generations1.We have long wondered whether ionizing radiation to parents, before conception, can cause gene mu.
