Influenza is a single stranded RNA virus that belongs to the Orthomyxoviridae family, influenza virus type A is responsible for the pandemics that have occurred in the past years. Influenza A are very complex and wide range viruses as they can occasionally jump between species. Improper disinfection can lead to a public health risk of a new influenza outbreak, for this reason it is important that correct sanitation processes are included in the control of these viruses. Viral inactivation is also used to remove infectious and suspicious samples from biosafety units and proper protocols for this are needed. This investigation aims to determine differences between two diferent influenza virus strains regarding their heat inactivation using different conditions of temperature and time. In this study a H1N1 influenza strain from avian origin and a H1N1 influenza strain from swine origin were used. Each virus was exposed to two different temperatures, 56 and 70 ºC, for five different time points (1 min, 5 min, 10 min and 15 min) using a dry bath. The results show that at 70 ºC both Swine and Avian H1N1 influenza strains were completely inactivated after 5 minutes. At 56 ºC Swine influenza virus H1N1 reached inactivation after 15 minutes but Avian influenza virus H1N1 did not reach inactivation. We could also determine that higher temperature increases the virus inactivation rate, when comparing 56 and 70 ºC. Both viruses at both temperatures were seen to follow a mono-phasic reduction tendency. |
