SARS-CoV-2 is a zoonotic coronavirus whose impact extends beyond the field of human health, since natural and experimental infection in animals has been reported, with the mammalian group being the most affected in both cases (1). This situation is alarming, since not only domestic animals are at risk but also those that inhabit natural environments such as aquatic habitats. The presence of SARS-CoV-2 has been reported in wastewater (2), which may contribute to the spread of the virus in fresh and salt water bodies. Also, direct interaction between humans and marine wildlife facilitates the spread of SARS-CoV-2 (3). Given the potential of SARS-CoV-2 to affect biodiversity, in silico studies help to predict the susceptibility of various species to the virus. For example, by comparative analysis of ACE2 sequences, marine mammals were detected as highly susceptible (4,5). Some of these marine mammals are species present in Peru; however, there are still no studies focused on the diversity of aquatic mammals in Peru. In addition, the discovery of new proteins involved in virus recognition and processing suggests the importance of performing a comprehensive in silico study for this group of animals. Therefore, the present work aims to determine the susceptibility to SARS-CoV-2 of Peruvian aquatic mammals inhabiting freshwater and saltwater bodies based on the level of conservation of key residues for Spike binding, present in ACE2, NPR1 and AGTR2 receptors, and in furin, TMPRSS2, cathepsins B/L (6) and TMPRSS4 (7) proteases. For this purpose, a comparison of the sequences of the orthologs of these proteins will be performed. In addition, 3D models of interaction of spike-receptor and spike-protease complexes will be included and the calculation of their binding free energy, variables that have not yet been integrated as a whole in in silico research works. Thus, estimating the susceptibility of the species of interest to the virus would motivate future in vitro and in vivo studies and contribute to the understanding of the impact of SARS-CoV-2 on aquatic biodiversity.
