Understanding processes driving pathogen transmission in bats is critical to prevent spillovers and emergence events. However, it requires fine-scale ecological investigations, which are rare because of the complexity and heterogeneity of bat populations. Here, based on the monitoring of 5,949 Reunion free-tailed bats (Mormopterus francoismoutoui) in 17 roosts over 24 months, we studied the simultaneous excretion of paramyxovirus andLeptospirabacteria in urine, and herpesvirus in saliva. We analysed the influence of individual and roost-level factors on co-excretion dynamics. We evidenced all year long excretion with high prevalence (37% - 87%), with low levels of temporal synchrony among roosts and no signal of density- dependent transmission. Recapture data support persistent infections for all infectious agents, alongside with clearance followed by reinfection for paramyxovirus andLeptospira. Our results suggest that sex-specific social behaviour or physiological adaptations drive herpesvirus excretion, while paramyxovirus andLeptospiraexcretion reactivate during reproduction. Our data also suggest the protection of juveniles by maternal antibodies, but different waning dynamics, much shorter for HSV infection, that could lead to a pathogen-dependent role of juveniles in the spread of infection. Interestingly, the excretion of one infectious agent was positively correlated to the excretion of a second one. However, the probability of excreting a third one was reduced for individuals already bi-excreting, suggesting negative interactions for cumulative infections. Connecting such spatio-temporal data with ecosystem alterations in Reunion Island could further contribute to our understanding of the links between human-mediated changes in the ecology of bats and infectious diseases emergence processes.Significance StatementUnderstanding risks of bat-borne pathogen spillover is challenging because of the difficulty in studying excretion dynamics in wild bat populations. Here, we used an original island-endemic model to build up a fine-scale spatio-temporal analysis of the excretion of two viruses (paramyxovirus and herpesvirus) and a bacterium (Leptospira) at both population- (roost) and individual- (through recaptured bats) levels. Excretion patterns are specific to each infectious agent and driven by the age and the reproduction of both females and males. Results also suggest that a combination of viral persistence and clearance, as well as interactions between infectious agents, are important within-host processes that contribute to the transmission of infections in bat populations. This information is crucial to better predict shedding pulses and prevent potential future spillovers.

Novel coronavirus species of public health and veterinary importance have emerged in the first two decades of the twenty-first century, with bats identified as natural hosts for progenitors of many coronaviruses. Targeted wildlife surveillance is needed to identify the factors involved in viral perpetuation within natural host populations, and drivers of interspecies transmission. We monitored a natural colony of Egyptian rousette bats at monthly intervals across two years to identify circulating coronaviruses, and to investigate shedding dynamics and viral maintenance within the colony. Three distinct lineages were detected, with different seasonal temporal excretion dynamics. For two lineages, the highest periods of coronavirus shedding were at the start of the year, when large numbers of bats were found in the colony. Highest peaks for a third lineage were observed towards the middle of the year. Among individual bat-level factors (age, sex, reproductive status, and forearm mass index), only reproductive status showed significant effects on excretion probability, with reproductive adults having lower rates of detection, though factors were highly interdependent. Analysis of recaptured bats suggests that viral clearance may occur within one month. These findings may be implemented in the development of risk reduction strategies for potential zoonotic coronavirus transmission.
