1. A vacina contra gripe pode provocar resultado positivo em testes para HIV em pessoas não infectadas pelo vírus?
A vacina contra gripe pode ocasionar resultados falso-positivos transitórios para HIV em pessoas não infectadas pelo vírus.
Por essa razão, se possível, pessoas que foram vacinadas e que necessitam realizar teste rápido ou laboratorial para HIV devem ser orientadas a adiar a realização do teste por pelo menos 30 dias após a realização da

2. A cavidade bucal pode anunciar a presença de sarampo?
Sim, por volta do terceiro a quarto dia da febre, surgem na cavidade bucal inúmeras máculas branco-azuladas ou branco-acinzentadas, medindo de 1 a 3 mm, circundadas por um halo eritematoso, indolores, localizadas na mucosa jugal, próximo ao ducto de desembocadura das glândulas parótidas (ducto de Stenon). Estas máculas aumentam em número e coales

3. Como deve ser o esquema de imunizações em puérperas?
As vacinas recomendas a todas as gestantes são
:
A vacina dTpa é suficiente para proteção contra o tétano neonatal e difteria em gestantes com história prévia de vacinação de dupla toxóide tetânico e difteria (dT) completa (3 doses) ou que tenham recebido duas doses de dT previamente. Em casos de vacinação incompleta, com apenas u

4. Serological response against bovine herpesvirus and bovine viral diarrhea virus induced by commercial vaccines in Holstein heifers
RESUMO: A vacinação é utilizada como estratégia para a prevenção e controle das doenças reprodutivas, causadas pelos vírus da diarreia viral bovina (BVDV) e herpesvírus bovino tipo 1 (BoHV-1), entretanto, as diversas composições de vacinas comerciais devem ser avaliadas quanto a sua eficiência protetiva mediada por anticorpos (Acs). O objetivo de

5. IMMUNIZATION STATUS OF PATIENTS WITH INFLAMMATORY BOWEL DISEASE
RESUMO CONTEXTO: No tratamento de doenças inflamatórias intestinais (DII) são usados imunossupressores e agentes biológicos, o que aumenta o risco de infecções pela alteração da imunidade celular e humoral. A prevenção de algumas dessas infecções pode ser feita pela vacinação, entretanto pacientes com DII apresentam baixas taxas de cobertura

6. Structure analysis of capsid protein of Porcine circovirus type 2 from pigs with systemic disease
Abstract Economic losses with high mortality rate associated with Porcine circovirus type 2 (PCV2) is reported worldwide. PCV2 commercial vaccine was introduced in 2006 in U.S. and in 2008 in Brazil. Although PCV2 vaccines have been widely used, cases of PCV2 systemic disease have been reported in the last years. Eleven nursery or fattening pigs suffering fr

7. First detection of dengue virus in the saliva of immunocompetent murine model
The lack of an experimental animal model for the study of dengue pathogenesis is a limiting factor for the development of vaccines and drugs. In previous studies, our group demonstrated the susceptibility of BALB/c mice to infection by dengue virus (DENV) 1 and 2, and the virus was successfully isolated in several organs. In this study, BALB/c mice were expe

8. Development and characterization of a packaging cell line for pseudo-infectious yellow fever virus particle generation
Abstract INTRODUCTION: Pseudo-infectious yellow fever viral particles (YFV-PIVs) have been used to study vaccines and viral packaging. Here, we report the development of a packaging cell line, which expresses the YFV prM/E proteins. METHODS: HEK293 cells were transfected with YFV prM/E and C (84 nt) genes to generate HEK293-YFV-PrM/E-opt. The cells were

9. Antiviral activity of animal venom peptides and related compounds
Abstract Viruses exhibit rapid mutational capacity to trick and infect host cells, sometimes assisted through virus-coded peptides that counteract host cellular immune defense. Although a large number of compounds have been identified as inhibiting various viral infections and disease progression, it is urgent to achieve the discovery of more effective agent

10. 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

11. Cissampelos sympodialis has anti-viral effect inhibiting dengue non-structural viral protein-1 and pro-inflammatory mediators
ABSTRACT Dengue is the most important viral infection transmitted among humans by arthropod-borne. There are currently no vaccines or specific therapeutical treatment. Therefore, immunomodulatory compounds from plants have been widely examined for their antiviral effects. Cissampelos sympodialis Eichler, Menispermaceae, has scientifically proven to present i

12. Infectious Bursal Disease: Pathogenicity and Immunogenicity of Vaccines
ABSTRACT The Infectious Bursal Disease (IBD) is a contagious viral disease that affects young chickens and may cause high morbidity and mortality. As the virus is very resistant to the environment, vaccination is required in case of high infection pressure. Due to variations in the virulence degree of the vaccines available to control IBD, this study aimed a
