Establishment and cryptic transmission of Zika virus in Brazil and the Americas
TLDR
Analyses of viral genomes with ecological and epidemiological data yield an estimate that ZikV was present in northeast Brazil by February 2014 and is likely to have disseminated from there, nationally and internationally, before the first detection of ZIKV in the Americas. Expand
Zika virus replication in the mosquito Culex quinquefasciatus in Brazil
TLDR
Interestingly, the presence of ZIKV in the midgut, salivary glands and saliva of artificially fed Cx. Expand
Horizontal Transposon Transfer in Eukarya: Detection, Bias, and Perspectives
TLDR
A straightforward hypothesis test is proposed that can be used by TE specialists and nonspecialists alike to discriminate between HTT events and natural TE life cycle patterns, and some of the methodological concerns for HTT detection are discussed. Expand
VHICA, a New Method to Discriminate between Vertical and Horizontal Transposon Transfer: Application to the Mariner Family within Drosophila
TLDR
A new automated method available as a R package “vhica” that discriminates whether a given TE family was vertically or horizontally transferred, and potentially infers donor and receptor species, appears as a valuable tool to analyze the evolutionary history of TEs across a large range of species. Expand
Genomic landscape and evolutionary dynamics of mariner transposable elements within the Drosophila genus
TLDR
This analysis is the first comprehensive survey of this family of transposable elements at a genus scale and provides precise measures of the different evolutionary processes that were hypothesized previously for this family based on PCR data analysis. Expand
Multiple introductions followed by ongoing community spread of SARS-CoV-2 at one of the largest metropolitan areas in the Northeast of Brazil
TLDR
This study sequenced 38 strains of SARS-CoV-2 from patients presenting Covid-19 symptoms in Pernambuco state, Brazil and detected that all except one strain showed the D614G spike protein amino acid change that may impact virus infectivity in human cells. Expand
Multiple Introductions Followed by Ongoing Community Spread of SARS-CoV-2 at One of the Largest Metropolitan Areas of Northeast Brazil
TLDR
This work sequenced 101 strains of SARS-CoV-2 from patients presenting Covid-19 symptoms that reside in Pernambuco and found that different from Southeastern Brazilian states where the epidemics were majorly driven by one dominant lineage, the early epidemic phase at the Pernamuco state was driven by multiple B.1.1 lineages seeded through both national and international traveling. Expand
Evolutionary Dynamics and Dissemination Pattern of the SARS-CoV-2 Lineage B.1.1.33 During the Early Pandemic Phase in Brazil
TLDR
The origin of the major and most widely disseminated SARS-CoV-2 Brazilian lineage B.1.1-like-like lineage may have been introduced from Europe or arose in Brazil in early February 2020 and a few weeks later gave origin to the lineage Batson-like, which is responsible for a variable fraction of the community viral transmissions in Brazilian states. Expand
The mobilome of Drosophila incompta, a flower-breeding species: comparison of transposable element landscapes among generalist and specialist flies
TLDR
Differences were found between species of the Sophophora and Drosophila subgenus, indicating there are lineage-specific factors shaping TE landscapes, and the absence of a clear pattern when comparing the TE landscape between generalist and specialist flies. Expand
