چکیده

Introduction: Severe acute respiratory syndrome coronavirus ۲ (SARS-CoV-۲) spilled over to humans via wild mammals, entering the host cell using angiotensin-converting enzyme ۲ (ACE۲) as receptor through Spike (S) protein binding. While SARS-CoV-۲ became fully adapted to humans and globally spread, some mammal species were infected back. The present study evaluated the potential risk of mammals becoming hosts for SARS-CoV-۲ through bioinformatics prediction based on ACE۲ receptors. Methods: We used evolutionary bioinformatic approaches and comparative analysis of ACE۲ critical residues that bind SARS-CoV-۲ S-protein and predicted potential SARS-CoV-۲ hosts among mammals and assessed their risk. Results: ACE۲ phylogenetic tree placed primates close to rodents and rabbits. Felines, rodents, and rabbits had higher ACE۲ similarities than human ACE۲ (hACE۲). Farmed animals, such as bovids, swine, and equids, had similar ACE۲ compared to hACE۲; however, these animals showed low SARS-CoV-۲ susceptibility. Some cetaceans also presented high similarities in ACE۲ key residues with hACE۲. Conclusion: Here, we showed wild and domestic mammals with a low divergence of ACE۲ compared to humans, discussing their possible chance of being infected, especially those animals kept as livestock or pets. Regarding the feasible transmission through contaminated water, cetaceans can be at risk of SARS-CoV-۲ infection. Extensive surveillance of SARS-CoV-۲ should be applied to prevent new coronavirus outbreaks and preserve mammals from infectious threats.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
