description | Aquatic animal viruses infect and transmit in aquatic environments, causing serious harm to the aquaculture industry and a variety of wild aquatic animals. How are they affected by environmental factors and do they represent potential threat to mammalian heath or not? Here, the effects of environmental factors (ultraviolet radiation (UV), temperature, pH, and drying) and their threshold on five epidemic aquatic animal viruses infecting amphibians and bony fish, including Rana grylio virus (RGV), Andrias davidianus ranavirus (ADRV), Grass carp reovirus (GCRV), Paralichthys olivaceus rhabdovirus (PORV), and Scophthalmus maximus rhabdovirus (SMRV), were measured and compared in a fish cell line. The examination of virus titers after different treatment in fish cells showed that the two iridoviruses, RGV and ADRV, had a higher tolerance to all of the environmental factors, such as they only had a decay rate of 22–36% when incubated at 37 °C for 7 days. However, the rhabdovirus SMRV was sensitive to all of the factors, with a decay rate of more than 80% in most of the treatments; even a complete inactivation (100%) can be observed after drying treatment. To address the potential threat to mammals, infectivity and limitation factors of the five viruses in Baby hamster kidney fibroblast cells (BHK-21) were tested, which showed that three of the five viruses can replicate at a low temperature, but a high temperature strongly inhibited their infection and none of them could replicate at 37 °C. This study clarified the sensitivity or tolerance of several different types of aquatic animal viruses to the main environmental factors in the aquatic environment and proved that the viruses cannot replicate in mammalian cells at normal physiological temperature. |
