Comparative Inactivation of Murine Norovirus and MS2 Bacteriophage by Peracetic Acid and Monochloramine in Municipal Secondary Wastewater Effluent

SUMMARYA preparation of infectious human rotavirus, isolated from faeces and resuspended in wastewater effluent, was shown to be inactivated by chlorine, chlorine dioxide, ozone and peracetic acid. Infectivity was assayed in MA 104 cells by the detection of cell-associated viral antigen by immunofluorescence. The inactivation curves were similar to those reported for other enteric viruses. Human rotavirus was at least as resistant as poliovirus, coxsackievirus, echovirus and f2coliphage and was strikingly less sensitive to inactivation than the simian rotavirus, SA11. The latter was generally the most sensitive of the six tested viruses yet is often taken as being representative of the human rotaviruses.

Presowing Treatment

Приведены данные двухлетнего исследования по поиску эффективных препаратов для обеззараживания семян капусты от сосудистого бактериоза. Наилучший результат был получен при предпосевной обработке 0,15%-ной надуксусной кислотой. При этом биологическая эффективность составляла 94,1–97,6%, что значительно превышало соответствующий показатель в эталонном варианте – Фитолавин, ВРК, 0,2% (69,0–72,0%). Показано, что заблаговременная обработка семян НУК (за 550 суток до посева) не оказывала достоверного влияния на их лабораторную всхожесть.Presented data are the result of a two-year study aimed at identifying effective preparations for the disinfection of cabbage seeds from black rot. The best result was obtained by presowing treatment with 0.15% peracetic acid. In this case, the biological efficiency was 94.1–97.6%, which significantly exceeded the corresponding indicator in the reference variant – Phytolavin, VRK, 0.2% (69.0–72.0%). The study has not revealed any significant effect of advance treatment of seeds with peracetic acid (550 days before sowing) on their laboratory germination.
