Summary and Perspectives on Current Disinfection Technologies in Reducing Antibiotic Resistant Bacteria and Their Resistance Genes

چکیده
薬剤耐性菌(ARB)と耐性遺伝子(ARGs)による水環境の汚染が問題となっている。現在の下水や排水の処理システムは必ずしもARBやARGsの除去を目的としておらず、下水処理場や合併浄化槽などの小規模排水処理システムはARBの主要な排出源であると同時に、ARGsの水平伝播のホットスポットであると考えられている。そのため、ARBへの感染リスクを低減するためには、下水処理場などにおけるARBやARGsの消長を明らかにする必要がある。本稿では、下水処理プロセスの三次処理となる消毒に焦点をあて、現在用いられている各種消毒技術を利用したプロセスの、ARBやARGs削減に関する利点、欠点とその改善に向けた取り組みについて概説した。また、ARBやARGsの水環境中への排出削減に向けて、今後望まれる方策や新技術開発など、更なる研究の方向性についてまとめた。

Comparison of different disinfection processes in the effective removal of antibiotic-resistant bacteria and genes.
This study compared three different disinfection processes (chlorination, E-beam, and ozone) and the efficacy of three oxidants (H2O2, S2O(-)8, and peroxymonosulfate (MPS)) in removing antibiotic resistant bacteria (ARB) and antibiotic resistance genes (ARGs) in a synthetic wastewater. More than 30 mg/L of chlorine was needed to remove over 90% of ARB and ARG. For the E-beam method, only 1 dose...
متن کاملFate of Antibiotic Resistant Bacteria and Genes during Wastewater Chlorination: Implication for Antibiotic Resistance Control
This study investigated fates of nine antibiotic-resistant bacteria as well as two series of antibiotic resistance genes in wastewater treated by various doses of chlorine (0, 15, 30, 60, 150 and 300 mg Cl2 min/L). The results indicated that chlorination was effective in inactivating antibiotic-resistant bacteria. Most bacteria were inactivated completely at the lowest dose (15 mg Cl2 min/L). B...
