dc.description.abstract <p><strong>Aims: </strong> The objective of this study was to estimate UV<sub>254</sub> inactivation constants for four viral pathogens: influenza virus type A, porcine respiratory and reproductive syndrome virus (PRRSV), bovine viral diarrhoea virus (BVDV) and reovirus.</p> <p><strong>Methods and Results: </strong> Viruses in culture medium were exposed to one of nine doses of UV<sub>254</sub> and then titrated for infectious virus. Analysis showed that viral inactivation by UV<sub>254</sub> was more accurately described by a two-stage inactivation model <em>vs</em> a standard one-stage inactivation model.</p> <p><strong>Conclusions: </strong> The results provided evidence for the existence of two heterogeneous viral subpopulations among the viruses tested, one highly susceptible to UV<sub>254</sub> inactivation and the other more resistant. Importantly, inactivation constants based on the one-stage inactivation model would have underestimated the UV<sub>254</sub> dose required for the inactivation of these viruses under the conditions of the experiment.</p> <p><strong>Significance and Impact of the Study: </strong> To improve the accuracy of estimates, it is recommended that research involving the inactivation of micro-organisms evaluates inactivation kinetics using both one-stage and two-stage models. These results will be of interest to persons responsible for microbial agents under laboratory or field conditions.</p>
