Resumo: This study aimed to investigate the occurrence of Lutzomyia longipalpis and also the canine visceral leishmaniasis (CVL) in a rural area of Ilha Solteira, state of São Paulo. Blood samples were collected from 32 dogs from different rural properties (small farms) and were analyzed by ELISA and the indirect immunofluorescence antibody test (IFAT) in order to diagnose CVL. From these serological tests, 31.25% of the dogs were positive for CVL and these were distributed in 66.7% (8/12) of the rural properties, which were positive for L. longipalpis. CDC (Center for Disease Control and Prevention) light traps were installed in 12 properties (one per property) and insects were caught on three consecutive days per month for one year. L. longipalpis was present on 100% of the rural properties visited, at least once during the twelve-month interval, totaling 64 males and 25 females. The insects were more numerous after the peak of the rain, but the association between prevalence of peridomestic vectors and the climatic data (precipitation, relative air humidity and temperature) and the occurrences of CVL among dogs on each rural property were not statistical significant (p <0.05). However, the occurrence of CVL cases in dogs and the presence of L. longipalpis indicate that more attention is necessairy for the control of this disease in the rural area studied.

O objetivo desse trabalho foi o estudo da prevalência de Lutzomyia longipalpis e da leishmaniose visceral canina (LVC) em uma área rural do município de Ilha Solteira do estado de São Paulo. Amostras de sangue foram coletadas de 32 cães provenientes de pequenas propriedades rurais e analisadas por meio dos métodos sorológicos ELISA (imunoensaio enzimático indireto) e RIFI (reação de imunofluorescência indireta) para o diagnóstico da LVC. Pelos exames sorológicos, dos 32 cães avaliados, 31,25% foram diagnosticados positivos para LVC, os quais estavam diostribuídos em 66,67% (8/12) das propriedades positivas para Lutzomyia longipalpis. Armadilhas luminosas do tipo CDC (Center for Disease Control and Prevention) foram instaladas em 12 propriedades, sendo uma por propriedade, e as coletas dos insetos foram realizadas três dias consecutivos a cada mês, durante um ano. O inseto L. longipalpis foi encontrado em 100% das propriedades visitadas, pelo menos uma vez no ano, totalizando 65 machos e 25 fêmeas. A maior quantidade de insetos foi observada principalmente após a ocorrência dos maiores picos de precipitação pluvial, mas a associação entre a prevalência dos vetores peridomiciliares e os dados climáticos (precipitação, umidade relativa do ar e temperatura) assim como a ocorrência da CVL em cães em cada propriedade não foi estatisticamente significante (p<0.05). No entanto, alerta-se que pela presença dos casos de LVC nos cães amostrados e também de L. longipalpis, maior atenção deve ser dada durante as investigações epidemiológicas para o controle dessa doença nessa área rural estudada.

Título: Expression of avian leukosis virus proteins p27 and p19 in uninfected chicken, drake and quail cells
Fonte: Rev. Inst. Adolfo Lutz;49(2):169-78, 1989. tab.
Idioma: en.
Resumo: Normal, uninfected animal cells have an unique feature, the presence in their genome of genes (proviruses) identical or closely related to infectious exogenous retrovirus. The level of expression of these genes varies from individual to individual; from complete silence to the production of virus particles. Exogenous and endogenous virus proteins were purified from sonicated viruses passed through a Sepharose 6B column satured with 6M guanidinium hydrochloride. The presence of equivalents of antigens p27 and p19 was analysed by radioimmunoassay. The presence of endogenous virus components was investigated in CEF, heart, brain, tigh muscle and wing muscle of chicken, quail and drake. The function or significance of the proteins are not known. Immunological, hormonal and environmental factors remain to be studied

Idioma: es.
Resumo: Resumen La infección crónica con virus oncogénicos es responsable de aproximadamente el 20% de todos los cánceres reportados en humanos, este proceso de oncogénesis viral presenta una naturaleza compleja, multietapa y multifactorial. Un ejemplo de ello es el Virus de Epstein- Barr (EBV), un herpesvirus que infecta de manera latente a más del 90% de la población. Aunque la infección a menudo cursa de manera asintomática, el EBV es capaz de modificar su expresión genómica estableciendo diferentes fases de latencia, alterando así el metabolismo de sus células blanco, como son los linfocitos B y las células epiteliales, proceso que resulta determinante en la aparición y desarrollo de diferentes patologías que van desde la mononucleosis infecciosa hasta procesos oncológicos como el linfoma de Burkitt, el cáncer gástrico o el cáncer nasofaríngeo.

Abstract Chronic infection with oncogenic viruses is responsible for approximately 20% of all cancers worldwide in humans, this viral transformation represents a complex, multistage and multifactorial process. An example is the Epstein-Barr virus (EBV), a herpesvirus that latently infects over 90% of the population. Although the infection often courses asymptomatically, EBV is able to modify its genomic expression by establishing different latency phases, thus altering the B lymphocytes and epithelial cells metabolism, a determinant process in the appearance and development of different pathologies ranging from infectious mononucleosis to oncological processes such as Burkitt's lymphoma, gastric cancer and nasopharyngeal cancer.

Título: In silico analysis of amino acid variation in human respiratory syncytial virus: insights into immunodiagnostics

Resumo: BACKGROUND The highly contagious nature of human respiratory syncytial virus (HRSV) and the gravity of its infection in newborns and vulnerable adults pose a serious public health problem. Thus, a rapid and sensitive diagnostic test for viral detection that can be implemented upon the first appearance of symptoms is needed. The genetic variation of the virus must be considered for immunodiagnostic purposes. OBJECTIVES To analyse HRSV genetic variation and discuss the possible consequences for capture immunoassay development. METHODS We performed a wide analysis of N, F and G protein variation based on the HRSV sequences currently available in the GenBank database. We also evaluated their similarity with homologous proteins from other viruses. FINDINGS The mean amino acid divergences for the N, F, and G proteins between HRSV-A and HRSV-B were determined to be approximately 4%, 10% and 47%, respectively. Due to their high conservation, assays based on the full-length N and F proteins may not distinguish HRSV from human metapneumovirus and other Mononegavirales viruses, and the full-length G protein would most likely produce false negative results due to its high divergence. MAIN CONCLUSIONS We have identified specific regions in each of these three proteins that have higher potential to produce specific results, and their combined utilisation should be considered for immunoassay development.

Título: Evolution of equine influenza viruses (H3N8) during a Brazilian outbreak, 2015

Resumo: 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 neuraminidase amino acid sequences were compared with the recent isolates from North and South America and the World Organisation for Animal Health recommended Florida Clade 1 vaccine strain. The hemagglutinin amino acid sequences had nine substitutions, compared with the vaccine strain. Two of them were in antigenic site A (A138S and G142R), one in antigenic site E (R62K) and another not in antigenic site (K304E). The four substitutions changed the hydrophobicity of hemagglutinin. Three distinct genetic variants were identified during the outbreak. Eleven variants were found in four quasispecies, which suggests the equine influenza virus evolved during the outbreak. The use of an out of date vaccine strain or updated vaccines without the production of protective antibody titers might be the major contributing factors on virus dissemination during this outbreak.

Título: Short interfering RNAs targeting a vampire-bat related rabies virus phosphoprotein mRNA

Resumo: Abstract The aim of this study was to assess the in vitro and in vivo effects of short-interfering RNAs (siRNAs) against rabies virus phosphoprotein (P) mRNA in a post-infection treatment for rabies as an extension of a previous report (Braz J Microbiol. 2013 Nov 15;44(3):879-82). To this end, rabies virus strain RABV-4005 (related to the Desmodus rotundus vampire bat) were used to inoculate BHK-21 cells and mice, and the transfection with each of the siRNAs was made with Lipofectamine-2000™. In vitro results showed that siRNA 360 was able to inhibit the replication of strain RABV-4005 with a 1 log decrease in virus titter and 5.16-fold reduction in P mRNA, 24 h post-inoculation when compared to non-treated cells. In vivo, siRNA 360 was able to induce partial protection, but with no significant difference when compared to non-treated mice. These results indicate that, despite the need for improvement for in vivo applications, P mRNA might be a target for an RNAi-based treatment for rabies.

Título: Human Cytomegalovirus DNA Quantification and Gene Expression in Gliomas of Different Grades
Fonte: Plos one;11(7), 2016.
Idioma: en.
Resumo: Gliomas are the most common type of primary brain tumors. The most aggressive type, Glioblastoma multiforme (GBM), is one of the deadliest human diseases, with an average survival at diagnosis of about 1 year. Previous evidence suggests a link between human cytomegalovirus (HCMV) and gliomas. HCMV has been shown to be present in these tumors and several viral proteins can have oncogenic properties in glioma cells. Here we have investigated the presence of HCMV DNA, RNA and proteins in fifty-two gliomas of different grades of malignancy. The UL83 viral region, the early beta 2.7 RNA and viral protein were detected in 73%, 36% and 57% by qPCR, ISH and IHC, respectively. Positivity of the viral targets and viral load was independent of tumor type or grade suggesting no correlation between viral presence and tumor progression. Our results demonstrate high prevalence of the virus in gliomas from Brazilian patients, contributing to a better understanding of the association between HCMV infection and gliomas worldwide and supporting further investigations of the virus oncomodulatory properties.

Título: Rotavirus genotypes and the indigenous children of Brazilian midwest in the vaccine era, 2008-2012: footprints of animal genome
Fonte: J. med. virol;87(11):1881-1889, 2015.
Idioma: en.
Resumo: World group A rotavirus (RVA) surveillance data provides useful estimates of the disease burden, however, indigenous population might require special consideration. The aim of this study was to describe the results of G­ and P­types from Brazilian native children ≤3 years. Furthermore, selected strains have been analyzed for the VP7, VP6, VP4, and NSP4 encoding genes in order to gain insight into genetic variability of Brazilian strains. A total of 149 samples, collected during 2008­2012, were tested for RVA using ELISA and PAGE, following by RT­PCR and sequencing. RVA infection was detected in 8.7% of samples (13/149). Genotype G2P[4] was detected in 2008 and 2010, G8P[6] in 2009, and G3P[8] in 2011. The phylogenetic analysis of the VP7 and VP4 genes grouped the Brazilian G2P[4] and G3P[8] strains within the lineages currently circulating in humans worldwide. However, the phylogenetic analysis of the VP6 and NSP4 from the Brazilian G2P[4] strains, and the VP7 and NSP4 from the Brazilian G3P[8] strains suggest a distant common ancestor with different animal strains (bovine, caprine, and porcine). The epidemiological and genetic information obtained in the present study is expected to provide an updated understanding of RVA genotypes circulating in the native infant population, and to formulate policies for the use of RVA vaccines in indigenous Brazilian people. Moreover, these results highlight the great diversity of human RVA strains circulating in Brazil, and an in­depth surveillance of human and animal RVA will lead to a better understanding of the complex dynamics of RVA evolution

Resumo: O sarampo é uma doença exantemática viral, altamente infecciosa, causada por um vírus da família Paramyxoviridae, gênero Morbillivirus que, apesar de estar disponível uma vacina, segura e eficaz contra a doença, esta ainda constitui uma importante causa de morbidade e mortalidade infantil em muitos países em desenvolvimento. Embora exista apenas um tipo antigênico do vírus do sarampo, estudos de caracterização genética dos vírus de tipo selvagem permitiram a identificação oito subtipos (A-H) e 24 genótipos. O Brasil eliminou a transmissão autóctone do vírus do sarampo a partir do ano 2000. A partir de então foram confirmados vários casos de sarampo importados ou relacionados a importações, principalmente do genótipo D4. A epidemiologia molecular dos vírus do sarampo baseada nas análises da região C-terminal da nucleoproteína tem demonstrado uma diversidade limitada entre as cepas circulantes, dificultando dessa forma a determinação da origem dos vírus usando apenas essa região. O objetivo deste trabalho foi caracterizar geneticamente os genótipos D4 dos vírus do sarampo detectados no Brasil no período de 2003 a 2012, e para tal, as sequências da proteína H completa e do gene N parcial foram analisadas. Os casos positivos para o genótipo D4 foram previamente identificados pela amplificação dos 450nt da região C-terminal da proteína N por RT-PCR, as sequências completas do gene H destas amostras foram diretamente amplificadas por RT-PCR a partir das amostras clínicas e posteriormente sequenciado.As análises filogenéticas da sequência de nucleotídeos do gene N e do gene H completomos traram que os vírus do sarampo genótipo D4 detectados no Brasil podem ser resultado de várias importações de diferentes variantes do mesmo genótipo que circulam na Europa. Foram identificadas mutações nas sequências de aminoácidos tantodo gene N parcial como do gene H completo dos genótipos D4 dos vírus do sarampo detectados no Brasil...

Measles is a highly infectious viral exanthem of the family Paramyxoviridae, genusMorbillivirus. Despite the availability of a safe and effective vaccine, measles infectioncontinues to be an important cause of infantile morbidity and mortality in developingcountries. Although there is only one antigenic type of the measles virus, geneticcharacterisation of the wild-type virus identified 8 subtypes (A-H), with a total of 24genotypes being recognised. From 2000, the indigenous transmission of the measlesvirus has been eliminated in Brazil. Since then, several cases of imported measles, orcases associated with importations, were confirmed, principally of genotype D4. Themolecular epidemiology of the measles virus based on analyses of the C-terminal regionof the nucleoprotein has demonstrated a limited diversity between circulating strains,making it difficult to determine the origin of the virus by this genomic region alone. Theobjective of this study was to genetically characterise the D4 genotype of measlesviruses detected in Brazil from 2003 to 2012 by analysing sequences from the completeH gene and partial N gene of the virus. Cases positive for measles genotype D4 werepreviously identified by the amplification of a 450nt of the C-terminal region of the Nprotein by RT-PCR. The complete H gene from these samples was amplified by RTPCRdirectly from clinical samples and subsequently sequenced. Phylogenetic analysisof the nucleotide sequences of the N gene and the complete H gene demonstrated thatthe measles D4 genotype detected in Brazil may have been a result of severalimportations of different variants of the same genotype circulating in Europe...

Resumo: An antiviral drug for treatment of dengue is an urgent necessity. In this study in silico activities of essential oils components on dengue virus (DENV) were evaluated, and beta-Caryophyllene was subjected to biological examination to assess inhibition of DENV-2 replication. Components previously optimized were coupled with viral proteins prepared, using AutoDock Vina. Theoretical affinity values varied between -4.0 and -7.3 kcal/mol. alpha-copaene, beta-bourbonene, germacrene D, spathulenol, beta-caryophyllene, caryophyllene oxide and (+)- epi-bicyclosesquiphellandrene showed the greatest interaction with viral proteins. beta-caryophyllene inhibits DENV-2 in vitro (50 percent inhibitory concentration [IC50] = 22.5 +/- 5.6 uM [4.6 +/- 1.1 ug/mL] and resulted non-cytostatic with a selectivity index value of 71.1. The in silico results permit infer that DENV proteins are potential targets for the concomitant docking of various essential oils components. Biological examination suggest that beta-caryophyllene acts on very early steps of the viral replication cycle and it might prove virucidal.

Una droga antiviral para tratamiento del dengue es una necesidad urgente. En este estudio se evaluó la actividad in silico de componentes de aceites esenciales sobre el virus del dengue (VDEN) y el beta-cariofileno se seleccionó para evaluar la inhibición sobre la replicación in vitro del VDEN-2. Los componentes previamente optimizados fueron acoplados con proteínas virales preparadas, utilizando AutoDock Vina. Los valores de afinidad variaron entre -4.0 and -7.3 kcal/mol. alfa-Copaeno, beta-bourboneno, germacreno D, spatulenol, beta- cariofileno, óxido de cariofileno y (+)-epi-biciclosesquifellandreno presentaron la mayor interacción con las proteínas virales. beta-Cariofileno inhibió VDEN-2 in vitro (Concentración inhibitoria 50 [IC50] = 22.5 +/- 5.6 uM [4.6 +/- 1.1 ug/mL] y resultó no-citostático con índice de selectividad de 71.1. Los resultados in silico indican que proteínas del VDEN son blancos potenciales para varios componentes. El análisis biológico sugiere que el beta-cariofileno actúa en etapas tempranas de la replicación viral y podría ser virucida.
