New strategies to eliminate persistent HIV-1 during therapy will benefit from animal models, such as non-human primates infected with simian immunodeficiency viruses (SIV) or chimeras (SHIV). Understanding the genetic composition of SIV and SHIV reservoirs during therapy is therefore crucial for the future application of this model.

Introduction: Bats are recognized as primary natural reservoirs for alpha- and betacoronaviruses. The interspecies transmission of bat coronaviruses to other mammalian hosts, including livestock and humans, can lead to epidemics, epizootics, and global pandemics.
Objective: This study aims to describe coronaviruses associated with horseshoe bats ( spp.
High astrovirus diversity in an endemic bat species suggests multiple spillovers from synanthropic rodents and birds.

Beyond the role of bats as natural host reservoirs of infectious agents, the impact of viral spillover from other animal species to bats has been neglected. Given the limited virus-host specificity of astroviruses (AstVs) and their propensity for cross-species transmission, we hypothesized that AstVs could be transmitted within animal communities (rodents, birds, and bats) and that native endemic bats may be exposed to viruses hosted by other species. We investigated the presence of AstV RNA in 3,796 biological samples collected in Reunion Island from ( = 3421), an endemic free-tailed bat species, and also from small terrestrial mammals and birds: ( = 146), ( = 74), ( = 36), ( = 99), and ( = 20).

Wild rodents serve as crucial reservoirs for zoonotic viruses. Anthropogenic and environmental disruptions, particularly those induced by mining activities, can destabilize rodent populations and facilitate the emergence of viral agents. In the Canaã dos Carajás and Curionópolis regions of Brazil, significant environmental changes have occurred due to mining expansion, potentially creating conditions conducive to the emergence of rodent-associated viral diseases.

Influenza A virus (IAV) is a significant public health concern, causing seasonal outbreaks and occasional pandemics. These outbreaks result from changes in the virus's surface proteins which include hemagglutinin and neuraminidase. Influenza A virus has a vast reservoir, including wild birds, pigs, horses, domestic and marine animals.

Bats act as reservoirs for a variety of zoonotic viruses, sometimes leading to spillover into humans and potential risks of global transmission. Viral shedding from bats is an essential prerequisite to bat-to-human viral transmission and understanding the timing and intensity of viral shedding from bats is critical to mitigate spillover risks. However, there are limited investigations on bats' seasonal viral shedding patterns and their related risk factors.
