2. 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

3. Molecular epidemiology of influenza A(H1N1)PDM09 hemagglutinin gene circulating in São Paulo State , Brazil: 2016 anticipated influenza season
ABSTRACT Compared to previous years, seasonal influenza activity commenced early in São Paulo State, Brazil, Southern hemisphere during the 2016 year. In order to investigate the genetic pattern of influenza A(H1N1)pdm09 in the State of Sao Paulo a total of 479 respiratory samples, collected in January by Sentinel Surveillance Units, were screened by real-t

4. 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

6. Presence of antibodies against H5, H7 and H9 influenza A virus in wild birds in the State of São Paulo, Brazil
Although the natural reservoirs of the avian influenza (AI) virus have been extensively studied in many countries, there is a clear lack of information on this subject in South America, particularly in Brazil. The objective of this study was to conduct a serological survey for H5, H7 and H9 antibodies to AI-subtype viruses in wild birds in the state of São

7. Efeito dos processos de irradiação e germinação nos aspectos nutricionais, sensoriais e microbiológicos em grãos de soja (Glycine m ax Merril) cultivar BRS216 / Effect of irradiation and germination processes in the nutritional, sensory and microbiological in soybeans (Glycine max Merrill) cultivra BRS216
Soybean (Gycine max (L.) Merrill) is an important legume for human diets due its potential health benefits. Because of the increasing stimulus to soybean consumption, mainly due to its several bioactive compounds, some processing methods have been studied as a way to know changes that occur in these compounds during the processes. Thus, this study aimed to a

8. Genetic diversity of hemagglutinin (HA) of Influenza A virus from 1995 to 2006. / Diversidade genética da hemaglutinina (HA) de vírus influenza A, entre 1995 e 2006
Os Influenzavirus podem ser classificados de acordo com suas glicoproteínas externas hemaglutinina (HA) e neuraminidase (NA), ambas apresentando alta variabilidade genética e antigênica. No presente estudo foi realizada análise molecular do gene HA, do vírus influenza A (IA) em amostras colhidas de crianças e lactentes com sintomatologia respiratória

9. Um enfoque multigênico para a genealogia comparada de Betacoronavirus em bovinos e equinos / A multigene approach for a compared genealogy of Betacoronavirus from cattle and horses
Gastroenteritis is one of the leading causes of morbidity and mortality amongst young and newborn animals, often caused by multiple intestinal infections, being rotavirus and Bovine coronavirus (BCoV) the main viral causes in cattle. BCoV has a worldwide distribution and caused diarrhea in calves, winter dysentery in adult cattle and respiratory disease, whi

10. Papel das hemaglutininas 67-72p de Corynebacterium diphtheriae na ligação a proteínas plasmáticas, superfícies celulares, invasão e indução de apoptose / Participation of hemagglutinin 67-72p of corynebacterium diphtheriae in binding to plasma proteins, cells surfaces, invasion and induction of apoptosis
Corynebacterium diphtheriae pode ser isolado tanto de quadros de difteria clássica, quanto de infecções sistêmicas, como endocardite. O fibrinogênio (Fbn) e a fibronectina (Fn) são glicoproteínas presentes na matriz extracelular de tecidos conjuntivos. A influência destas proteínas na patogênese das infecções locais e invasivas causadas por C. di

12. Structure-function analysis of two variants of mumps virus hemagglutinin-neuraminidase protein
A point mutation from guanine (G) to adenine (A) at nucleotide position 1081 in the hemagglutinin-neuraminidase (HN) gene has been associated with neurovirulence of Urabe AM9 mumps virus vaccine. This mutation corresponds to a glutamic acid (E) to lysine (K) change at position 335 in the HN glycoprotein. We have experimentally demonstrated that two variants
