Highly Diverse Arenaviruses in Neotropical Bats, Brazil
Emerging Infectious Diseases
|November 23, 2022
Summary
Bats in Brazil carry arenaviruses, including Tacaribe virus and a new species, Tietê mammarenavirus. This research highlights bats as a significant, underrecognized reservoir for these potentially dangerous viruses.
Area of Science:
- Virology
- Zoonotic Diseases
- Mammalogy
Background:
- Arenaviruses are a significant public health concern, with rodents being the primary known reservoir.
- Bat populations are increasingly recognized as potential reservoirs for various zoonotic viruses.
Purpose of the Study:
- To investigate the prevalence of arenaviruses in Brazilian bat populations.
- To identify specific arenavirus species circulating in bats and characterize novel findings.
Main Methods:
- RNA detection of arenaviruses in bat samples collected in Brazil between 2007 and 2011.
- Identification of virus species through molecular methods.
Main Results:
- Arenavirus RNA was detected in 1.6% of 1,047 bats sampled.
- Tacaribe virus was identified in two Artibeus sp. bats.
- A novel arenavirus species, named Tietê mammarenavirus, was discovered in Carollia perspicillata bats.
Conclusions:
- Bats harbor diverse arenaviruses, including previously unknown species.
- The findings suggest bats are an underrecognized reservoir for arenaviruses, necessitating further research into their role in virus transmission and public health implications.

RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

Plants often form mutualistic relationships with soil-dwelling fungi or bacteria to enhance their roots’ nutrient uptake ability. Root-colonizing fungi (e.g., mycorrhizae) increase a plant’s root surface area, which promotes nutrient absorption. While root-colonizing, nitrogen-fixing bacteria (e.g., rhizobia) convert atmospheric nitrogen (N2) into ammonia (NH3), making nitrogen available to plants for various biological functions. For example, nitrogen is essential for the...

Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.

Hyperthermophilic archaea are a group of extremophiles thriving at temperatures above 80°C, often in hydrothermal vents and volcanic soils where conditions surpass the boiling point of water. At such temperatures, proteins, membranes, and DNA in most organisms degrade, but hyperthermophiles have evolved remarkable adaptations to maintain stability and function.Unique Cellular FeaturesHyperthermophilic membranes are composed of a monolayer of biphytanyl tetraether lipids, which resist...

Amoebozoa represent a diverse group of terrestrial and aquatic protists that utilize lobe-shaped pseudopodia for locomotion and feeding. This characteristic differentiates them from the Rhizaria, which possess threadlike pseudopodia. The primary classifications within Amoebozoa include gymnamoebas, entamoebas, and the plasmodial and cellular slime molds. Phylogenetic evidence indicates that Amoebozoa diverged from a lineage that ultimately gave rise to fungi and animals.Gymnamoebas and...

Crenarchaeota, a prominent phylum of Archaea, is remarkable for its ability to thrive in extreme environments characterized by high temperatures and acidity. These microorganisms inhabit sulfuric hot springs, volcanic systems, and submarine hydrothermal vents, where temperatures often exceed 100°C. The unique adaptations of Crenarchaeota not only allow survival under such extreme conditions but also provide insights into the mechanisms of life in primordial Earth-like...
