1. Human astrovirus types 1, 4 and 5 circulating among children with acute gastroenteritis in a rural Brazilian state, 2010-2016

   ARCHIVES OF VIROLOGY, v.166, n.11, p.3165-3172, 2021

   This study combined conventional epidemiology of human astroviruses. From 2010 to 2016, 232 stool samples from children under 5 years of age were screened using NGS and conventional RT-PCR followed by genetic analysis in order to investigate the genotypic diversity of classical human astrovirus (...

2. Evaluation of loop-mediated isothermal amplification assay for detection of Clostridioides difficile infection: A prospective diagnostic performance study

   ANAEROBE, v.71, article ID 102410, 4p, 2021

   A novel Loop-mediated isothermal amplification (LAMP) assay, HiberGene's CD was evaluated with 82 unformed stools from patients suspected of C. difficile infection (CDI). Compared to glutamate dehy-drogenase (GDH) toxins A/B test (C.diff Quik Chek (R)), HiberGene's LAMP showed 100% of sensitivity...

3. Quantification of airborne SARS-CoV-2 genomic particles in different hospital settings

   SCIENTIFIC REPORTS, v.11, n.1, article ID 21284, 6p, 2021

   We quantified the presence of SARS-CoV-2 RNA in the air of different hospital settings and the autopsy room of the largest medical centre in Sao Paulo, Brazil. Real-time reverse-transcription PCR was used to determine the presence of the envelope protein of SARS-CoV-2 and the nucleocapsid protein...

4. Diagnosis of human strongyloidiasis: Application in clinical practice

   ACTA TROPICA, v.223, article ID 106081, 8p, 2021

   This review considers the advantages and disadvantages of parasitological techniques, methods of detecting antibodies and antigens, as well as molecular biology techniques in the diagnosis of human strongyloidiasis. In addition, it elucidates the potential of different techniques for rapid and ef...

5. Evaluation of targets for Strongyloides genus specific molecular diagnosis in experimental strongyloidiasis

   EXPERIMENTAL PARASITOLOGY, v.230, article ID 108157, 6p, 2021

   Strongyloides venezuelensis has been used in different experimental studies, such as those aimed at the evaluation of diagnostic techniques for human strongyloidiasis, mainly the molecular diagnosis. In this study, three regions (genus, 18S and 28S targets) of Strongyloides ribosomal DNA were eva...

6. Toxocara DNA amplification in serum and tissue samples in BALB/c mice

   MOLECULAR AND BIOCHEMICAL PARASITOLOGY, v.246, article ID 111429, 4p, 2021

   Toxocariasis is still a neglected parasitic disease worldwide and much about its biology and diagnosis has yet to be understood. The migration of third stage larvae via bloodstream suggests a potential use of molecular tools in diagnosis as well to deepen the knowledge about its migration behavio...

7. Serological screening for Chagas disease in an endemic region of Northern Minas Gerais, Brazil: the SaMi-Trop project

   REVISTA DO INSTITUTO DE MEDICINA TROPICAL DE SAO PAULO, v.63, article ID e67, 7p, 2020

   Chagas disease (CD) is still a neglected disease. Infected individuals are diagnosed late, being treated in worse clinical conditions. Thus, this study aimed to analyze the prevalence and the factors associated with new confirmed cases of CD identified by serological screening in an endemic regio...

8. Clusters of SARS-CoV-2 Lineage B.1.1.7 Infection after Vaccination with Adenovirus-Vectored and Inactivated Vaccines

   VIRUSES-BASEL, v.13, n.11, article ID 2127, 13p, 2021

   A SARS-CoV-2 B.1.1.7 variant of concern (VOC) has been associated with increased transmissibility, hospitalization, and mortality. This study aimed to explore the factors associated with B.1.1.7 VOC infection in the context of vaccination. On March 2021, we detected SARS-CoV-2 RNA in nasopharynge...

9. Use of medical face masks versus particulate respirators as a component of personal protective equipment for health care workers in the context of the COVID-19 pandemic

   ANTIMICROBIAL RESISTANCE AND INFECTION CONTROL, v.9, n.1, article ID 126, 7p, 2020

   Currently available evidence supports that the predominant route of human-to-human transmission of the SARS-CoV-2 is through respiratory droplets and/or contact routes. The report by the World Health Organization (WHO) Joint Mission on Coronavirus Disease 2019 (COVID-19) in China supports person-...

10. Implications of a highly divergent dengue virus strain for cross-neutralization protection, and vaccine immunity

    CELL HOST & MICROBE, v.29, n.11, p.1634-+, 2021

    Although divergent dengue viruses (DENVs) have been isolated in insects, nonhuman primates, and humans, their relationships to the four canonical serotypes (DENV 1-4) are poorly understood. One virus isolated from a dengue patient, DKE-121, falls between genotype and serotype levels of sequence d...
