Increasing dengue outbreaks in temperate Brazil are associated with Aedes aegypti invasion and infestation levels

Dengue fever, caused by dengue virus (DENV), is one of the most significant mosquito-borne diseases globally, with increasing risk due to the expansion of Aedes vectors into subtropical and temperate zones. Brazil accounted for 70% of dengue cases reported worldwide in 2024, and the virus has recently become ende...

Genomic epidemiology of human parvovirus B19 in Southern Brazil, 2015–2024

Human parvovirus B19 (B19V) causes erythema infectiosum and, in severe cases, has been associated with hydrops fetalis and transient aplastic crises. Despite its clinical importance, particularly in vulnerable groups such as pregnant women and immunocompromised individuals, epidemiological and genomic data on B19V rema...

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

Genomic characterization of highly pathogenic avian influenza A(H5N1) clade 2.3.4.4b into wild seabirds from coastal Ecuador

Findings provide genomic evidence of repeated H5N1 introductions into Ecuador as part of the regional spread of the virus along the eastern Pacific coast and support sustained surveillance across wildlife, animal-health, and public-health sectors.

Assessment of Culex quinquefasciatus microbiota and the impact of Lysinibacillus sphaericus larvicide exposure on susceptible and resistant strains.

The findings indicate that L. sphaericus resistance phenotype seems to have a limiting effect of diversity found in both life stages, while susceptible females surviving L. sphaericus exposure showed a marked restructuring.

Molecular DNA enrichment methods for parasite genomic sequencing in clinical samples: a systematic review.

It is emphasized that parasite DNA enrichment is essential for enabling WGS in clinical settings, underscoring the need for protocol standardization and cost-effectiveness analyses to support public health genomic surveillance.

Chromosome-Level Genome of Simulium vittatum Links Black Fly Cytogenetics to Genome Organization and Evolution

This reference genome connects classical black fly cytogenetics with sequence-level analyses of genome organization, structural variation, and gene content, addressing a major genomic gap within Culicomorpha and providing a foundation for comparative studies of chromosome evolution, hematophagy, and vector biology acro...
