西北大学的一项研究表明，美国家庭中的牙刷和淋浴喷头中藏有大量噬菌体，即针对细菌的病毒。 A Northwestern University study reveals that toothbrushes and showerheads in American homes harbor numerous bacteriophages, viruses that target bacteria. 预计这一结果是由于这些物品的潮湿环境造成的。 This finding is expected due to the damp environments of these items. 虽然微生物对个人构成的风险最小,但共用牙刷可能导致感染。 While the microbes present pose minimal risk to individuals, sharing toothbrushes could lead to infections. 建议定期清洁:醋中浸泡的淋浴头和在空气干燥前用热水冲洗牙刷。 Regular cleaning is advised: soak showerheads in vinegar and rinse toothbrushes with hot water before air drying.
