“…Various investigators have reported that microorganisms play a role in the inactivation of enteroviruses (Magnusson et al 1967;Matossian and Garabedian 1967;Shuval et al 1971;Denis et al 1977;Fujiokaet al 1980;, bacteriophage (Mitchell 1971), and fish viruses in the aquatic environment, although the events involved in this inactivation process are unknown.…”

“…Antiviral activity, mainly against enteroviruses, has been detected in marine water samples from a broad range of geographic areas including the Mediterranean (Plissier and Therre 1961), Red (Shuval et al 1971), North and Baltic (Magnusson et al 1967) seas, the Gulf of Mexico (Akin et al 1975;Labelle and Gerba 1980), and the Atlantic (Lo et al 1976;Denis et al 1977;Plissier and Hugues 1978) and Pacific (Fujioka et al 1980) oceans. In most instances, this antiviral activity was directly or indirectly associated with growth activities of marine microorganisms.…”

The mechanism of enterovirus inactivation by marine bacteria was investigated using poliovirus type 1 as a model virus and with strains of Pseudomonas and Vibrio isolated from the marine environment. Treatment of virus with cell-free filtrates from late log phase bacterial cultures produced alterations in the viral capsid as shown by a reduction in efficiency of adsorption to host cells, increased sensitivity to ribonuclease, and by the release of ribonucleic acid from the treated virions. Filtration of 14C-labelled, treated virus through 25-nm filters revealed that the majority of the isotope (85-96%) passed the filters, indicating extensive capsid disruption. However, the most rapid and pronounced change observed during virus inactivation was the loss of infectivity, suggesting that enzymatic degradation is not the first event in the poliovirus inactivation process by marine bacteria.

“…Additionally, the ability of bacteria to inactivate viruses is usually lost while subculturing the microorganisms in the laboratory (Gunderson et al 1968 ;Katzenelson 1978 ), although in a few studies, such bacteria could be subcultured for more than 1 year without losing their antiviral activity (Gironés et al 1990 ;Bosch et al 1993 ). In some studies, the virucidal agents in the tested waters could not be separated from the microorganisms (Shuval et al 1971 ;Denis et al 1977 ;Fujioka et al 1980 ;Ward et al 1986 ;Gironés et al 1990 ), whereas in others the virucidal activity could be separated from the bacteria (Matossian and Garabedian 1967 ;O'Brien and Newman 1977 ;Toranzo et al 1983 ;Bosch et al 1993 ). The antiviral activity seems to be based on proteolytic bacterial enzymes that inactivate virus particles in water by cleavage of viral proteins, thus exposing the viral RNA to nuclease digestion (Toranzo et al 1983 ;Gironés et al 1990 ;Bosch et al 1993 ).…”

“…These sewageborne human enteric viruses become a potential public health problem only if they are able to survive in the marine environment and be disseminated to recreational and shellfish-producing coastal waters. Seawater from various sources (Mediterranean Sea, Red Sea, Baltic Sea, North Sea, Atlantic Ocean, and the Gulf of Mexico) has been reported to contain antiviral activity (1,2,(6)(7)(8)10). However, there appears to be no consensus as to the component of these waters responsible for the antiviral activity.…”

The stability of certain human enteroviruses in the Hawaiian ocean environment was examined. The present data indicated that the time for 90% reduction of poliovirus type 1 at 24 ± 1°C in seawater samples obtained from different sites in Hawaii ranged from 24 to 48 h, and complete inactivation occurred within 72 to 96 h. The accumulated evidence also strongly indicated that a virus-inactivating agent(s) of a microbiological nature was present in both clean and sewage-polluted seawaters, but not in fresh, mountain stream waters. The antiviral activity was lost when the seawater samples were subjected to boiling, autoclaving, or filtration through a 0.22or 0.45-,um, but not a 1.0-,um, membrane filter. That the antiviral activity of the seawater was related to the growth activities of microorganisms was corroborated by the observed effects of added nutrients, a lower temperature of incubation, and the presence of certain antibiotics. Other enteric viruses, such as coxsackie virus B-4 and echo virus-7, were also shown to be similarly inactivated in seawater. which receives sewage discharge and stream and stormn water runoffs. As compared with the above coastal water samples, water from Pearl Harbor is characterized by high turbidity, high nutrient level, and in-1105
