Sambucus nigra (elder) are broadly used species to treat microbial infections. Thepotential antiviral activity and mechanism action of elder fruit (EF) in human epithelium cell(A549) cultures infected with H9N2 influenza virus were determined. The effect of variousconcentrations of EF on influenza virus replication was examined by using virus titration,quantitative real time RT-PCR, fusion and ...
The H1N1 virus is one of the highly contagious strains that leads to epidemic influenza every year in winter. In this outbreak sometimes rare complications of this infection occur. This report presents a rare case of encephalitis caused by H1N1 virus in a 52-year old man. After a day fever and flu like symptoms the patient was admitted in hospital due to decreased level of consciousness. ...
Background: Currently, with increasing risk of influenza A virus epidemics, a lot of studies have been performed. Oseltamivir or Tamiflu (the neuraminidase (NA) inhibitor) is one of the effective drugs for preventing and treatment of these viruses. The H274Y mutation is from the most important drug resistant factors in influenza A viruses. The aim of this study was detection of Oseltamivir...
Background and Objectives: Influenza is an acute viral respiratory disease. Given the importance of influenza preventive behaviors, the present study aimed at determining the effect of education based on preventive behaviors of Influenza A among the students in Qom city. Methods: This interventional study was conducted on 200 tenth-grade male students in Qom city. The samples were assigned t...
Introduction: The influenza vaccine is one of the controversial challenges in today's societies. Considering the importance of using the flu vaccine in preventing the spread of influenza virus, the Twitter network, as a rich source of data, provides suitable conditions for research in this field to examine the attitudes of different people about this vaccine. The results in one hand will help h...
Background and Aims: Influenza vaccination is one of the best way to prevent and control influenza worldwide. It is manufactured by WHO-licensed companies based on the WHO expertise committee annually. The aim of this study was partial quality control of the commercial human influenza vaccine 2008-9 and its matching with the circulating strains. Materials and Methods: The trivalent imported vac...
High morbidity and mortality of influenza virus infection makes it an important disease world-wide. Mouse is a very well-studied animal model for this disease with similar manifestation to human disease. It would be desirable to induce mucosal as well as circulating immune responses to obtain protection from infection and to decrease the spread of the virus. Cell mediated immunity (proliferativ...

BackgroundHospital-acquired potentiall...
Influenza virus is a seasonal respiratory pathogen that produces global pandemics by genome reassortments. This rapid evolution creates difficulty in producing vaccines. Although several anti-influenza drugs have been developed, acquisition of drug resistance viruses common. Therefore, it important to develop novel therapeutic and prophylactic strategies. In this study, we evaluated the antivir...
