Ilhéus virus (ILHV) is a neglected mosquito-borne flavivirus. ILHV infection may lead to fever, an emerging febrile disease like dengue fever with the potential evolve into severe neurological characterized by meningoencephalitis; no specific treatments are available for this disease. This study assessed antiviral properties of caffeic acid, abundant component plant-based food products that also compatible socioeconomic limitations associated infectious The in vitro activity acid on...
Nanoparticles (NPs) have a wide range of applications in various areas. For health application, cytotoxicity tests are used to ensure its efficiency and safety. In this paper, ZnFe2O4, CoFe2O4, Zn0.5Co0.5Fe2O4 NPs were synthesized, characterized their antibacterial properties evaluated. The Sol-Gel method was synthesize the NPs. Their electronic crystallographic structures by Fourier Transform Infrared Spectroscopy Analysis (FTIR), X-ray fluorescence (XRF), X-Ray Diffraction (XRD),...
Avian species pose risks for transmitting viruses, including avian circoviruses, that could be a threat conservation and introduction into commercial flocks. This study investigated the presence of circovirus in 81 from different regions Brazil, northwest region São Paulo coast Paraná. Blood samples oropharyngeal, cloacal, other organ swabs were collected. The extracted screened using nested PCR replicase gene. In positive cases, sequenced. Regarding results, total 1528 swab collected 601...
Chikungunya virus (CHIKV) and Zika (ZIKV) are important disease-causing agents worldwide. Currently, there no antiviral drugs or vaccines approved to treat these viruses. However, peptides have shown great potential for new drug development. A recent study described (p-BthTX-I)2K [(KKYRYHLKPF)2K], a peptide derived from the Bothropstoxin-I toxin in venom of Bothrops jararacussu snake, showed activity against SARS-CoV-2. In this study, we assessed CHIKV ZIKV its action different stages viral...
Recent seroprevalence studies in animals detected Rocio virus regions of Brazil, indicating risk for re-emergence this pathogen. We identified RNA samples from 2 human patients whom dengue fever was clinically suspected but ruled out by laboratory findings. Testing infrequent flavivirus infections should expedite diagnoses.
In Brazil, Mato Grosso (MT) has the highest number of hantavirus cardiopulmonary syndrome cases. Our study aimed to identify anti-hantavirus antibodies in sera patients from Sinop, MT, presenting with acute febrile illness.A retrospective analysis data for 198 samples assessed using enzyme-linked immunosorbent assay (ELISA) was conducted.Immunoglobulins G (IgGs) against nucleoprotein were found 13.6% tested sera. No sample had immunoglobulin M (IgM) hantavirus. Seropositivity occurred mainly...
Abstract The Brazilian regions are still highly endemic areas for Canine morbillivirus [canine distemper virus (CDV)]. However, little is known regarding the genetic variability of strain circulating in several regions. Here, we report first full-length genome and molecular characterization CDV isolated from domestic dogs Center-West region. Sequence alignment phylogenetic analyses based on deduced amino acid nucleotide sequences showed that characterized as South America-I/Europe genotype....
The emergence of several SARS-CoV-2 lineages presenting adaptive mutations is a matter concern worldwide due to their potential ability increase transmission and/or evade the immune response. While performing epidemiological and genomic surveillance in samples from Porto Ferreira-São Paulo-Brazil, we identified sequences classified by pangolin as B.1.1.28 harboring Spike L452R mutation, RBD region. Phylogenetic analysis revealed that these grouped into monophyletic branch, with others...
O diagnóstico laboratorial passou por várias mudanças devido à automatização. Além do aparelhamento, a adoção de um programa garantia qualidade (PGQ) está resultando em maior precisão nos exames. Para fins controle qualidade, o processamento uma amostra biológica é didaticamente dividido três fases: pré-analítica, analítica e pós-analítica. Na fase pré-analítica ocorre maioria dos erros; divulgação dessas falhas sua discussão corroboram para eficiência PGQs. No presente estudo, descrevemos...
