Severe zoonotic viruses carried by different species of bats and their regional distribution.

BACKGROUND

Bats have garnered increased attention in the field of life sciences for their typical biological characteristics of carrying a variety of zoonotic viruses without disease, long lifespans, low tumorigenesis rates, and high metabolism. When it was found that bats can carry the rabies virus, over 60 years of research revealed that bats host over 4100 distinct viruses, including Ebola virus and SARS-CoV.

OBJECTIVES

This paper primarily reviews the profiles of zoonotic viruses carried by bats across various regions globally. The review aims to provide a foundation and reference for future research on monitoring zoonotic viruses in diverse global regions and bat species, exploring the coevolutionary relationship between bats and viruses, understanding the tolerance mechanisms of bat B cells, prevention, and treatment of zoonotic diseases caused by bats.

CONTENT

A total of 147 references were obtained. Surveys on severe zoonotic virus carriage have been limited to only 83 bat species belonging to nine families, which are distributed all over the world. We also briefly describe the antibody responses and B-cell molecules in bats.

IMPLICATIONS

Several viruses have been found in different species of bats. This suggests that bats may be important hosts for future viral infectious diseases. Particularly in recent years, the close correlation between human infection pandemics caused by coronaviruses and bats highlights the pressing need to comprehend the species, tolerance, and coevolutionary mechanisms of zoonotic viruses carried by different bat species.
