Outline of Annual Research Achievements

1.(1)2018/2019 年の全国6か所小児科371下痢便検体でロタウイルス45.6%、ノロウイルス GII 22.9%、ヒトパレコウイルス5.4%、サポウイルスとアデノウイルス各 4.9%、エンテロウイルス 4.6%、アストロウイルス3.5%、ノロウイルス GI 0.5%の順であった。2018/2019はロタウイルスの地域的流行が見られノロウイルスを凌駕した。(2)ロタウイルスはG8P[8]I2型が90%を超えた。ワクチンに含まれない遺伝子型が多く見られ年ごと代わった。(3)2歳のロタウイルス患者にG1-P[8]-I1-R1-C1-M1-A1-N1-T1-E2-H1、すなわちNSP4遺伝子(E2)の組換え株を見出した。(4)ノロウイルスはGII.4_Sydneyが多いが、GII2,GII.6なども認めた。
2.2018年のロタウイルスワクチン推定接種率はさらに上昇し81%となった。ワクチンに含まれないG8,G9型に対しても重症化を防いだ。さらに検査法としてRT-PCRのみならずイムノクロマト法も有用であった。
3. 104例のロタウイルスワクチン接種者、非接種者の年齢別血清IgG抗体価の推移をELISA法で調べた。成人非接種者37例では抗体価は高く、年齢が下がると抗体価は減少した。繰り返しの感染で抗体価が高く維持された。この事は成育マウスを用いたロタウイルス、ノロウイルスの同時皮下接種実験でもI期2回接種で長い抗体価の維持と一致する。
4.ロタウイルス感染時の抗原血症・尿症をイムノクロマト法で見出した。ワクチン非接種者は多く、ワクチン接種者は少なかった。重症度スコアとも一致した。
5.2015年から2018年、定期的に回収した空気中、雨水中の下痢症ウイルス遺伝子をRT-PCR法で調べた。期間中ロタウイルスおよびノロウイルスがあるも、台風、黄砂、雪とは無関係であった。
