Discovery of two potential new species and two novel bat-coronavirus subgenera (Phyllacovirus and Phyllobecovirus) in the Neotropics

The paper identifies two new bat coronavirus subgenera and potential species from Neotropical bats using metatranscriptomic sequencing and phylogenetic analysis.

Genomics insights reveal multi-year maintenance of a new Deltacoronavirus infecting Seabirds from the Cagarras Island Archipelago Natural Monument, Brazil

The paper detects deltacoronaviruses in seabirds from Brazil, identifies full and draft genomes, and finds evidence of long-term viral maintenance through reinfection and immune escape mutations.

Detection of Deltacoronavirus in Environmental Fecal Samples from Seabirds in the Saint Peter and Saint Paul Archipelago, central equatorial Atlantic Ocean

The paper detects deltacoronaviruses in environmental fecal samples from seabirds in the Saint Peter and Saint Paul Archipelago using RT-PCR and metatranscriptomics.

Ambecovirus, a novel Betacoronavirus subgenus circulating in neotropical bats sheds new light on bat-borne coronaviruses evolution

The paper identifies a new Betacoronavirus subgenus, Ambecovirus, in Neotropical bats, revealing its phylogenetic position and potential for interspecies transmission.

Detection and full genome sequencing of a Deltacoronavirus and other bird associated viruses from feces of the kelp gull (Larus dominicanus) sampled at the South Shetland Islands Antarctica.

The paper detects a deltacoronavirus in kelp gull fecal samples from Antarctica and sequences its full genome, revealing its classification and potential cross-species transmission.

Highly divergent and diverse viral community infecting sylvatic mosquitoes from Northeast Brazil

This study characterizes the RNA virome of sylvatic mosquitoes in Northeast Brazil, identifying 16 viral families and 34 new viral species with high RdRp divergence.

Emergence and Spread of the SARS-CoV-2 Variant of Concern Delta Across Different Brazilian Regions
