Evolution and divergence of the genetic lineage Desmodus rotundus/Artibeus lituratus of rabies virus in São Paulo State. Arch Virol 2023; 168:266.

Abstract
The last record of a rabies case caused by the dog-specific rabies virus (RABV) lineage in dogs or cats in São Paulo State was in 1998. From 2002 to 2021, 57 cases of rabies in these animals were reported, and the vast majority (51) were genetically characterized as belonging to the Desmodus rotundus/Artibeus lituratus RABV lineage. However, it is not currently possible to infer which of these bats is the source of infection by genome sequencing of RABV isolates. The aims of this study were (a) to characterize the Desmodus rotundus/Artibeus lituratus lineage to determine the relationships between the RABV lineages and each reservoir, (b) to assess the phylogeny and common ancestors of the RABV lineages found in D. rotundus and A. lituratus, and (c) to further understand the epidemiology and control of rabies. In this study, we genetically analyzed 70 RABV isolates from São Paulo State that were received by the Virology Laboratory of the Pasteur Institute of São Paulo between 2006 and 2015. Of these isolates, 33 were associated with the hematophagous bat D. rotundus and 37 with the fruit bat A. lituratus. A genomic approach using phylogenetic analysis and nucleotide sequence comparisons demonstrated that these isolates belonged to the same genetic lineage of RABV. We also found that, in São Paulo State, the D. rotundus/A. lituratus lineage could be subdivided into at least four phylogenetic sublineages: two associated with D. rotundus and two with A. lituratus. These results are of importance for the epidemiological surveillance of rabies in São Paulo.

Abstract
Bats host a large variety of viruses, including some that may infect other vertebrates and humans. Research on bat-borne viruses attracted significant attention in recent years mainly due to epizootics caused by viruses having bats as hosts. The characterization of the viral communities of bats was then prioritized, but despite increasing efforts, there are large disparities in the geographical ranges covered and the methodologies employed around the world. As a result, large gaps remain in our current understanding of bat viromes and their role in disease emergence. This is particularly true for megadiverse regions in Latin America. This review aims to summarize the current understanding about bat viruses that inhabit Brazilian biomes, one of the most bat species-rich and diverse regions of the globe. Taking into account all known bat-associated viral families studied in Brazilian biomes, we found that almost half of all bat species (86/181 species) were not investigated for viruses at all. Moreover, only a small fraction of viral lineages or families have been studied more in depth, usually employing targeted methods with limited power to characterize a broad virus diversity. Additionally, these studies relied on limited spatiotemporal sampling and small sample sizes. Therefore, our current understanding of bat viral communities in the Brazilian biomes is limited and biased at different levels, limiting zoonotic risk assessments of bat-borne viruses. Considering these limitations, we propose strategies to bridge the existing gaps in the near future. IMPORTANCE Bat-borne viruses have attracted much attention due to zoonotic outbreaks with large consequences to humans. Because of that, virus characterization in bats has been prioritized in tropical regions of the globe. However, bat-virus research in Latin America and particularly in Brazil, which are among the most bat species-rich regions of the world, are highly biased toward zoonotic viruses and known bat reservoir species. These results have direct implication for virus studies in general but also for new zoonotic virus and spillover events characterization. The limited knowledge we currently have about the virome of Brazilian bats drastically limits any broad assessment of zoonotic viruses they carry and calls for coordinated and large-scale studies to fill this crucial knowledge gap.

Rabies virus isolated from insectivorous bats induces different inflammatory responses in experimental model. J Neuroimmunol 2022; 373:577974. [PMID: 36270078 DOI: 10.1016/j.jneuroim.2022.577974] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2022] [Revised: 09/18/2022] [Accepted: 09/28/2022] [Indexed: 01/12/2023]
Abstract
Rabies virus (RABV) is a neurotropic virus that causes fatal neuroinflammation in mammals. The insectivorous bat RABV strains are less pathogenic for mice than strains associated with other reservoirs. We characterized the tissue inflammatory response in the CNS of RABV isolated from insectivorous bats. Eptesicus furinalis (EPBRV)-infected mice had a robust inflammatory response and a greater amount of IL-1β, IL-6 and TNF-α, while Myotis nigricans (MNBRV)-infected mice showed a higher expression of IL-17 and greater activation of IFN-β. New approaches to understand the inflammatory response to different mechanisms of action may provide insights for the development of novel therapies for rabies.

Abstract
Bats are essential to the global ecosystem, but their ability to harbour a range of pathogens has been widely discussed, as well as their role in the emergence and re-emergence of infectious diseases. This paper describes the first report of coinfection by two zoonotic agents, rabies virus (RABV) and the fungus Histoplasma suramericanum in a bat. The bat was from the Molossus molossus species, and it was found during the daytime in the hallway of a public psychiatric hospital in a municipality in São Paulo State, southeastern Brazil. RABV infection was diagnosed by the direct fluorescent antibody test and mouse inoculation test. The fungus was isolated by in vitro culture. Both diagnoses were confirmed by molecular techniques. Phylogenetic analysis showed that the fungus isolate had proximity to H. suramericanum in the Lam B clade, while the RABV isolate was characterized in the Lasiurus cinereus lineage. Since the M. molossus bat was found in a peri-urban transition area (urban/peri-urban), the possibility of cross-species transmission of this RABV lineage becomes more plausible, considering that this scenario may provide shelter for both M. molossus and L. cinereus. These are relevant findings since there has been an increase in bat populations in urban and peri-urban areas, particularly due to environmental modifications and anthropogenic impacts on their habitat. Thus, the detection of two zoonotic agents in a bat found in a public hospital should raise awareness regarding the importance of systematic surveillance actions directed towards bats in urban areas.

Nyctinomops laticaudatus bat-associated Rabies virus causes disease with a shorter clinical period and has lower pathogenic potential than strains isolated from wild canids. Arch Virol 2019; 164:2469-2477.

Abstract
Rabies is a lethal viral disease that can affect a wide range of mammals. Currently, Rabies virus (RABV) in some European and American countries is maintained primarily in wild species. The regulation of viral replication is one of the critical mechanisms involved in RABV pathogenesis. However, the relationship between replication and the pathogenesis of RABV isolated from wild animals remains poorly understood. In the present study, we evaluated the pathogenicity of the street viruses Nyctinomops laticaudatus bat-associated RABV (NYBRV) and Cerdocyon thous canid-associated RABV (CECRV). Infection of mice with NYBRV led to 33% mortality with rapid disease evolution and marked histopathological changes in the CNS. In contrast, infection with CECRV led to 67% mortality and caused mild neuropathological lesions. The proportion of RABV antigen was significantly higher in the cytoplasm of neuronal cells of the cerebral cortex and in the meninges of mice infected with CECRV and NYBRV, respectively. Moreover, the replication rate of NYBRV was significantly higher (p < 0.001) than that of CECRV in neuroblastoma cells. However, CECRV replicated to a significantly higher titer in epithelial cells. Our results indicate that NYBRV infection results in rapid disease progression accompanied by frequent and intense histopathological alterations in the CNS in mice, and in a high replication rate in neuroblastoma cells. Although, CECRV is more pathogenic in mice, it caused milder histopathological changes in the CNS and replicated more efficiently in epithelial cells. Our data point to a correlation between clinical aspects of disease and the replication of RABV in different cell lines.
