2. Molecular characterization of virulence genes cctA, nanA, and fliC in Clostridium chauvoei from Rio Grande do Sul and São Paulo State, Brazil
RESUMO: Toxina A de Clostridium chauvoei (CctA), neuraminidase (NanA) e flagelina (FliC) são proteínas que contribuem para a patogenicidade de Clostridium chauvoei, o agente causador do carbúnculo sintomático em bovinos. O objetivo deste estudo foi analisar a variabilidade genética dos genes cctA, nanA, e fliC em C. chauvoei isolados em diferentes per�

3. Evolution of equine influenza viruses (H3N8) during a Brazilian outbreak, 2015
Abstract Equine influenza is one of the major respiratory infectious diseases in horses. An equine influenza virus outbreak was identified in vaccinated and unvaccinated horses in a veterinary school hospital in São Paulo, SP, Brazil, in September 2015. The twelve equine influenza viruses isolated belonged to Florida Clade 1. The hemagglutinin and neuramini

4. Surveillance of antiviral resistance markers in Argentina: detection of E119V neuraminidase mutation in a post-treatment immunocompromised patient
Although vaccines are the best means of protection against influenza, neuraminidase inhibitors are currently the main antiviral treatment available to control severe influenza cases. One of the most frequent substitutions in the neuraminidase (NA) protein of influenza A(H3N2) viruses during or soon after oseltamivir administration is E119V mutation. We descr

5. Lectin activity in mycelial extracts of Fusarium species
ABSTRACT Lectins are non-immunogenic carbohydrate-recognizing proteins that bind to glycoproteins, glycolipids, or polysaccharides with high affinity and exhibit remarkable ability to agglutinate erythrocytes and other cells. In the present study, ten Fusarium species previously not explored for lectins were screened for the presence of lectin activity. Myce

6. Vaginose bacteriana em gestantes adolescentes: perfil de citocinas proinflamatórias e sialidases bacterianas. Estudo transversal
RESUMO CONTEXTO E OBJETIVO: A vaginose bacteriana é uma condição, comum em gestantes, que aumenta a susceptibilidade a infecções sexualmente transmissíveis (IST). Considerando que adolescentes são desproporcionalmente afetadas por IST, o objetivo deste estudo foi avaliar os níveis cervicovaginais de interleucina (IL)-1 beta, IL-6, IL-8 e sialidases

7. Comparative study of lymphocytes from individuals that were vaccinated and unvaccinated against the pandemic 2009-2011 H1N1 influenza virus in Southern Brazil
ABSTRACTINTRODUCTION:While no single factor is sufficient to guarantee the success of influenza vaccine programs, knowledge of the levels of immunity in local populations is critical. Here, we analyzed influenza immunity in a population from Southern Brazil, a region with weather conditions that are distinct from those in the rest of country, where influenza

8. Oseltamivir-resistant influenza A(H1N1)pdm2009 strains found in Brazil are endowed with permissive mutations, which compensate the loss of fitness imposed by antiviral resistance
The 2009 pandemic influenza A virus outbreak led to the systematic use of the neuraminidase (NA) inhibitor oseltamivir (OST). Consequently, OST-resistant strains, carrying the mutation H275Y, emerged in the years after the pandemics, with a prevalence of 1-2%. Currently, OST-resistant strains have been found in community settings, in untreated individuals. T

9. Whole-genome sequences of influenza A(H3N2) viruses isolated from Brazilian patients with mild illness during the 2014 season
The influenza A(H3N2) virus has circulated worldwide for almost five decades and is the dominant subtype in most seasonal influenza epidemics, as occurred in the 2014 season in South America. In this study we evaluate five whole genome sequences of influenza A(H3N2) viruses detected in patients with mild illness collected from January-March 2014. To sequence

10. Molecular findings from influenza A(H1N1)pdm09 detected in patients from a Brazilian equatorial region during the pandemic period
After the World Health Organization officially declared the end of the first pandemic of the XXI century in August 2010, the influenza A(H1N1)pdm09 virus has been disseminated in the human population. In spite of its sustained circulation, very little on phylogenetic data or oseltamivir (OST) resistance is available for the virus in equatorial regions of Sou

11. Neuraminidase inhibitors for preventing and treating influenza in healthy adults and children
BACKGROUND:Neuraminidase inhibitors (NIs) are stockpiled and recommended by public health agencies for treating and preventing seasonal and pandemic influenza. They are used clinically worldwide.OBJECTIVE:To describe the potential benefits and harms of NIs for influenza in all age groups by reviewing all clinical study reports of published and unpublished ra

12. Oseltamivir-resistant influenza A(H1N1)pdm09 virus in southern Brazil
The neuraminidase (NA) genes of A(H1N1)pdm09 influenza virus isolates from 306 infected patients were analysed. The circulation of oseltamivir-resistant viruses in Brazil has not been reported previously. Clinical samples were collected in the state of Rio Grande do Sul (RS) from 2009-2011 and two NA inhibitor-resistant mutants were identified, one in 2009
