This study aimed to verify the diversity of Culicidae species and their frequency infection with flaviviruses alphaviruses in Cuiabá, state Mato Grosso, Brazil. Mosquitoes were captured Nasci aspirators hand net 200 census tracts, identified alive at level pooled one-20 (11,090 mosquitoes, 14 species). Female pools (n = 610) subjected multiplex seminested-reverse transcription-polymerase chain reaction (RT-PCR) for 11 flavivirus five alphavirus. Positive tested by single RT-PCR followed...
This study aimed to investigate the circulation of Orthobunyavirus species in state Mato Grosso (MT) Brazil. During a dengue outbreak 2011/2012, 529 serum samples were collected from patients with acute febrile illness symptoms for up five days and 387 pools female Culex quinquefasciatus captured 2013 subjected nested-reverse transcription-polymerase chain reaction segment S Simbu serogroup followed by nucleotide sequencing virus isolation Vero cells. Patients (5/529; 0.9%) Cuiabá (n = 3),...
Mayaro virus (MAYV) is frequently reported in Pan-Amazonia. The aim of this study was to investigate the circulation alphaviruses during a dengue outbreak state Mato Grosso, Brazil. Serum samples from dengue-suspected patients were subjected multiplex semi-nested reverse transcriptase polymerase chain reaction for 11 flaviviruses and five alphaviruses, nucleotide sequencing viral isolation. MAYV detected 15 (2.5%) 604 patients. Twelve co-infected with 4, which isolated 10 molecular detection...
Mayaro virus (MAYV) is an arbovirus that circulates in Latin America and emerging as a potential threat to public health. Infected individuals develop fever, severe inflammatory disease characterized by high rash, arthralgia, myalgia headache. The often associated with prolonged arthralgia mediated chronic inflammation can last months. Although the immune response against other arboviruses, such chikungunya (CHIKV), dengue (DENV) Zika (ZIKV), has been extensively studied, little known about...
Abstract Vertical transmission to progeny ensures the maintenance of arboviruses in their natural vectors. This mechanism is largely reported for dengue virus (DENV) and yellow fever (YFV). Few studies have addressed this Zika (ZIKV), Mayaro (MAYV) other arboviruses. The present study investigated infection rate by 4490 Aedes ( Stegomyia ) aegypti 296 albopictus (Diptera: Culicidae reared from eggs collected with ovitraps Cuiabá, Mato Grosso State, February July, 2017. After viral RNA...
Dengue is the most prevalent arboviral disease in tropical areas. In Mato Grosso, outbreaks are reported every year, but studies on dengue this state scarce.Natural transovarial infection of Aedes aegypti by a flavivirus was investigated Jardim Industriário neighborhood Cuiabá, Grosso. Eggs were collected with ovitraps during dry, intermediate, and rainy seasons 2012. After eggs hatched larvae developed to adulthood, mosquitoes (n = 758) identified allocated pools 1-10 specimens according...
Mayaro virus (MAYV) is a neglected arthropod-borne (arbovirus) antigenically clustered into the Semliki Forest complex group of Alphavirus genus ( Togaviridae family), maintained in an unclear zoonotic cycle involving mosquitoes from Haemagogus as main vector. The genome composed positive single-stranded RNA 11.5 kb length, which contains two genes that encode four nonstructural (nsP1 to nsP4) and five structural (C, E3, E2, 6K, E1) proteins.
Viruses are ubiquitous and diverse microorganisms arising as a result of interactions within their vertebrate invertebrate hosts. Here we report the presence different viruses in salivary glands 1657 mosquitoes classified over 28 culicinae species from North region Brazilian Pantanal wetland through metagenomics, viral isolation, RT-PCR. In total, 12 were found, eight putative novel with relatively low similarity pre-existing families, named Pirizal iflavirus, Furrundu phlebovirus, Pixé...
DENV-2 was the main responsible for a 70% increase in dengue incidence Brazil during 2019. That year, our metagenomic study by Illumina NextSeq on serum samples from acute febrile patients (n = 92) with suspected arbovirus infection, sampled 22 cities of state Mato Grosso (MT), middle west Brazil, revealed eight complete genomes and two near-complete sequences genotype III, one Human parvovirus B19 I (5,391 nt) Coxsackievirus A6 lineage D (4,514 nt). These share aminoacidic identities BR4 E...
Abstract New species of insect‐specific viruses (ISV) have been reported worldwide. In the present study, complete genome Culex flavivirus (CxFV) and partial sequences other ISVs in quinquefasciatus Say 1823 females (n = 3425) sampled 200 urban areas census tracts Cuiaba, state Mato Grosso, were identified via reverse transcriptase‐polymerase chain reaction for a NS5 region flaviviruses, nucleotide high‐throughput sequencing, viral isolation C6/36 cells. CxFV was detected 16 403 mosquito...
In the present study we evaluated features of different recombinant forms Zika virus (ZIKV) proteins produced in either bacterial (Eschericha coli) or insect cells (Drosophila melanogaster). The ZIKV-envelope glycoprotein (EZIKV) is responsible for entry into host cells, main target neutralizing antibodies and has been used as a antigen serological tests development subunit vaccines. EZIKV composed three structural functional domains (EDI, EDII, EDIII), which share extensive sequence...
Introduction: Chikungunya chronic joint disease causes debilitating arthralgia, significantly impacting the quality of life affected individuals. Methods: In this study, patients underwent clinical follow-ups, biopsies, and pre-biopsy 24 months post-biopsy serum dosage cytokines. Results: All participants were female had pain in 12 joints on average, with 41.17% exhibiting moderate activity. Histopathological analysis revealed collagen deposition. Indirect immunofluorescence detected CHIKV...
INTRODUCTION The epidemiology of Rickettsia and Ehrlichia species infection is underestimated in Mato Grosso State. METHODS: Serum samples obtained during a Dengue outbreak 2011-2012 were tested via indirect immunofluorescence and/or ELISA. RESULTS: Samples from 19/506 (3.8%) patients presented antibodies for at least one three species; 2/506 (0.4%) reacted against canis. Most afflicted are residents cities the south-central region state, where these diseases have been reported animals....
INTRODUCTION: Aedes aegypti and Culex quinquefasciatus are vector species responsible for the transmission of important arboviruses. METHODS: Adult mosquitoes were collected in urban areas four municipalities Mato Grosso within 1 year. RESULTS: A total 19,110 collected. Among them, 16,578 (86,8%) C. (44% female 56% male); 2,483 (13%), A. (Stegomyia) (54% 46% 49 (0,30%), from genus Psorophora, Anopheles, Coquilettidia, Sabethes. significant correlation was observed between number all dew...
