Potential harmful effects of viral hemorrhagic septicemia virus in mammals

“…Several previous studies showed that VHSV could survive outside the host for varying periods of time depending upon the physicochemical conditions of the aqueous medium, such as water temperature, organic materials, and salinity (Hawley & Garver, 2008;Kocan et al, 2001;Parry & Dixon, 1997). VHSV survived for longer periods at 4℃ than at 20℃ (Parry & Dixon, 1997), which agrees with the results of other studies (Hawley & Garver, 2008;Joiner et al, 2020). Nevertheless, Joiner et al (2020) reported that VHSV suspended in MEM at 25℃ could survive for 50 days, and Pham et al (2011) showed that VHSV survived on the surface of the culture plate for 6 days at 37℃.…”

VHSV could also replicate and cause CPE in mouse (BHK/21) and human Diem Tho Ho, et al…”

“…The results obtained from our study are consistent with those of Samal et al (1998), who reported that the SBR virus inoculated into mammalian-derived cell lines (Vero and bovine) at 35℃ disappeared after 7 days, whereas it remained constant at 22℃. Washing the cells used in this study might not have been enough to remove the virus attached to the surface of the cells as other studies (Joiner et al, 2020;Pham et al, 2011;Yoshinaka et al, 2000) reported that washing and centrifuging procedures could not completely remove the virus attached to the surface of bacterial cells and other environmental matrices.…”

Evaluation of intra- and inter-lab variability in quantifying SARS-CoV-2 in a state-wide wastewater monitoring network

“…It has been reported that some environmental water quality factors, such as pH and temperature, may have an effect on viral particles in various matrices including wastewater. [65][66][67] However, due to low sample numbers and the limited range of data, it would be appropriate to design a study in a more systematic way to better understand the effects of environmental factors on the human fecal markers in wastewater if needed in the future.…”

Persistence of Tilapia tilapinevirus in fish rearing and environmental water and its ability to infect cell line

“…Therefore, the application of filter membranes with different elution buffers or pre‐acidification of water samples could improve the recovery rate of the virus (Bernhardt et al., 2021; Kongprajug, Chyerochana, et al., 2021; Li et al., 2010; Weli et al., 2021). The application of a filtered membrane to trap viruses in water is a common protocol to study the persistence of human and aquatic viruses (Ahmed et al., 2020; Haramoto et al., 2020; Joiner et al., 2021; Kongprajug, Chyerochana, et al., 2021; Kongprajug et al., 2021; Weli et al., 2021). For example, the electronegative charge filtered membrane was used in the study of the persistence of infectious salmon anaemia virus (ISAV) and salmon alphavirus (SAV) in seawater (Bernhardt et al., 2021; Weli, Tartor, Spilsberg, Dale, et al., 2021).…”
