Four experiments were conducted to determine the virocidal effects of rose bengal in the presence and absence of light on coxsackievirus types A9 and B4 and echovirus type 7. Based on these preliminary experiments, the three important variables were the viral types, dye concentration and contact time used in the presence of light. Rose bengal at a concentration of 10 mg/L (10-5 M) in the presence of light resulted in inactivation of the echovirus 7 within 24 hours. However, 1 mg/L (10-6M) of dye in the presence of light failed to achieve that same result in 48 hours when coxsackievirus A9 and B4 were treated. The latter was the most resistant, which is not surprising in that this virus has been isolated from many environmental samples of wastewater, ground and surface waters. Because of its resistance, coxsackie B4 was subjected to varyinq concentrations of rose bengal dye. A very minimal amount of virus was demonstrated at 42 hours in the presence of 2 mg/L (2x10-6M) of dye and light. However, all virus was inactivated by 42 hours in the presence of 4 and 6 mg/L (4 and 6x10-6M, respectively). Implications of these results are considered. |
