Sequencing and Description of the Mitochondrial Genome of (Diptera: Culicidae).

The genus Theobald, 1904 (Diptera: Culicidae) comprises 36 wild mosquito species, with distribution largely restricted to tropical and temperate areas, most of which are not recognized as vectors of epidemiological importance due to the lack of information related to their bionomy and involvement in the cycle transmission of infectious agents. Furthermore, their evolutionary relationships are not completely understood, reflecting the scarcity of genetic information about the genus. Therefore, in this study, we report the first complete description of the mitochondrial genome of a Neotropical species representing the genus, Coquillet, 1906, collected in the Brazilian Amazon region.

Evaluation of Multiple RNA Extraction Protocols for Chikungunya Virus Screening in Mosquitoes.

(, ; CHIKV) is a mosquito-borne global health threat. The main urban vector of CHIKV is the mosquito, which is found throughout Brazil. Therefore, it is important to carry out laboratory tests to assist in the virus's diagnosis and surveillance.

Genomic characterization of a novel Hepatovirus identified in Maranhão state, Brazil.

Bats are efficient reservoirs of a number of viruses with zoonotic potential, and are involved directly in the transmission cycle of many zoonoses. In the present study, which is part of a larger project that is documenting the viromes of the bat species found in the Mid-North states of Maranhão and Piauí, we analyzed 16 pooled samples obtained from four species of bat of the genus Artibeus-Artibeus obscurus, Artibeus cinereus, Artibeus lituratus and Artibeus planirostris. We describe and identify a Hepatovirus, denominated Hepatovirus H isolate sotense, which was found in a pool of internal organs (liver and lungs) extracted from a specimen of A.

A novel hantavirus identified in bats (Carollia perspicillata) in Brazil.

Bats play an essential role in maintaining ecosystems. Their unique characteristics increase the likelihood of interactions with various species, making them a potential source for the emergence and spread of infectious diseases. Hantaviruses are continuously expanding their range of hosts.

Genus Linnaeus, 1758 (Diptera: Culicidae) as an Important Potential Arbovirus Vector in Brazil: An Integrative Review.

The genus has 817 species subdivided into 28 subgenera. It has a cosmopolitan distribution, being most abundant in countries with a tropical climate. Understanding the ecology and diversity of viruses circulating in the species of this genus is important for understanding their role as arbovirus vectors in Brazil.

Vector Competence of for Yellow Fever Virus: Risk of Reemergence of Urban Yellow Fever in Brazil.

The risk of the emergence and reemergence of zoonoses is high in regions that are under the strong influence of anthropogenic actions, as they contribute to the risk of vector disease transmission. Yellow fever (YF) is among the main pathogenic arboviral diseases in the world, and the Culicidae has been proposed as having the potential to transmit the yellow fever virus (YFV). This mosquito inhabits both urban and wild environments, and under experimental conditions, it has been shown to be susceptible to infection by YFV.

Vector Competence of from Brazil for .

is characterized as a neurotropic pathogen, which can cause West Nile fever and is transmitted by mosquitoes of the genus . In 2018, the Instituto Evandro Chagas performed the first isolation of a WNV strain in Brazil from a horse brain sample. The present study aimed to evaluate the susceptibility of orally infected from the Amazon region of Brazil to become infected and transmit the WNV strain isolated in 2018.

Sequencing and description of the complete mitochondrial genome of Limatus durhamii (Diptera: Culicidae).

The genus Limatus (Diptera: Culicidae) are wild mosquitoes belonging to the Sabethini tribe that occurs in tropical countries and is related to transmission cycles of Orthobunyavirus (Bunyaviridae), particularly in the Amazon region. Given the unavailability of information related to evolutionary biology and molecular taxonomy aspects of this genus, we report here the first complete sequencing of the mitochondrial genome of Limatus durhamii Theobald, 1901. The NextSeq 500 platform was used for sample sequencing, and the mitochondrial sequence obtained was 14,875 bp long, comprising 37 functional subunits (13 PCGs, 22 tRNA and 02 rRNA).

Description of the mitogenome and phylogeny of Aedes spp. (Diptera: Culicidae) from the Amazon region.

The genus Aedes (Diptera: Culicidae) includes species of great epidemiological relevance, particularly involved in transmission cycles of leading arboviruses in the Brazilian Amazon region, such as the Zika virus (ZIKV), Dengue virus (DENV), Yellow fever virus (YFV), and Chikungunya virus (CHIKV). We report here the first putatively complete sequencing of the mitochondrial genomes of Brazilian populations of the species Aedes albopictus, Aedes scapularis and Aedes serratus. The sequences obtained showed an average length of 14,947 bp, comprising 37 functional subunits, typical in animal mitochondria (13 PCGs, 22 tRNA, and 2 rRNA).

Description of mitochon genome and phylogenetic considerations of Sabethes bipartipes, Sabethes cyaneus, Sabethes quasicyaneus, and Sabethes tarsopus (Diptera: Culicidae).

The genus Sabethes (Diptera: Culicidae) comprises species of great epidemiological relevance, particularly involved in transmission cycles of the Yellow fever virus in South America. Given the unavailability of information related to aspects of evolutionary biology and molecular taxonomy of species of this genus of mosquitoes, we report here the first sequencing of the mitochondrial genomes of Sabethes bipartipes, Sabethes cyaneus, Sabethes tarsopus, and Sabethes quasicyaneus. The sequences obtained showed an average length of 14,920 bp, comprising 37 functional genes (13 PCGs, 22 tRNA, and 02 rRNA).
