Abstract | Methods developed in the laboratory were used to measure inactivation rates of enteric viruses seeded into freshwaters from a variety of sources. All freshwater samples caused a decrease in poliovirus-1 infectivity of less than 98% within 4 days at 27 deg C. Virus inactivation was irreversible because particles dissociated in proportion to loss of infectivity. Other enteric viruses, i.e., echovirus-12, coxsackievirus B5, and rotavirus SA-11, were also shown to be inactivated in these waters. Thus, freshwaters contain virucidal factors which should reduce the public health risks associated with fecal contamination of these waters. (Copyright (c) 1986, American Society for Microbiology.) |
