Abstract
Background: Bat-borne hantaviruses have been identified worldwide but little is known about neotropical bats in the megadiverse biomes of the American continent. Although serological evidence has hinted at hantavirus circulation in Brazil, the scarce number of genomic detection represents a gap to understand viral diversity, prevalence, and ecology of bat-borne hantaviruses.
Objective: We aim to investigate and evaluate the presence and prevalence of bat-borne hantavirus in the Brazilian Atlantic Forest.
Methods: Here in, 97 lung and kidney tissue samples from bats captured in the Brazilian Atlantic Rainforest were submitted to hantavirus-specific nested reverse transcription-polymerase chain reaction (RT-PCR) targeted the hantaviral L segment and metagenomic analysis.
Findings: Hantavirus RNA was detected in five tissue fragments of 20 Seba's short-tailed bats (Carollia perspicillata). Phylogenetic analysis, based on partial L-segment sequence using maximum likelihood method, demonstrated that the identified virus formed a monophyletic clade and a highly divergent bat-borne lineage comprising other recent strains found in the genus Carollia from South America.
Main conclusions: Our findings suggest the presence of a novel bat-borne hantavirus in Brazil, tentatively named Mamanguape virus (MGPV). Additional genomic data will help to extend our knowledge about the classification of MGPV within the Hantaviridae family and the evolution origins of new world bat-borne hantaviruses.
期刊介绍：
Memórias do Instituto Oswaldo Cruz is a journal specialized in microbes & their vectors causing human infections. This means that we accept manuscripts covering multidisciplinary approaches and findings in the basic aspects of infectious diseases, e.g. basic in research in prokariotes, eukaryotes, and/or virus. Articles must clearly show what is the main question to be answered, the hypothesis raised, and the contribution given by the study.
Priority is given to manuscripts reporting novel mechanisms and general findings concerning the biology of human infectious prokariotes, eukariotes or virus. Papers reporting innovative methods for diagnostics or that advance the basic research with these infectious agents are also welcome.
It is important to mention what we do not publish: veterinary infectious agents research, taxonomic analysis and re-description of species, epidemiological studies or surveys or case reports and data re-analysis. Manuscripts that fall in these cases or that are considered of low priority by the journal editorial board, will be returned to the author(s) for submission to another journal.
