Background and Aims: Rubella virus is a human pathogen that causes congenital rubella syndrome (CRS) when infection occurs during early pregnancy. Vaccination programs have been remarkably successful in controlling natural rubella infection and CRS. Moreover, ongoing surveillance for all cases of rubella and CRS is a vital component of a prevention program. Although the WHO recommends the use o...

Background: White spot syndrome virus (wssv) is the causing agent for white spot disease in shrimp and many crustaceans. This disease is highly contagious and can cause death within 3–10 days under normal culture conditions. Therefore, early diagnosis of the virus is a necessity. Materials and Methods: Primers were designed for three regions of the virus genome and one region of the shrimp geno...

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 ...

Abstract : Avian influenza virus (AIV) infection is a major cause of influenza mortality in birds and can cause human mortality and morbidity. Although the risk of infection with avian influenza virus (AIV) is generally low for most people, the pathogenic virus can cross the species barrier and acquires the ability to infect and be transmitted among the human population; therefore the ra...

Background and Aims: The emergence of drug-resistant influenza viruses has become a serious threat for human and animal populations. Glycyrrhiza glabra (Gg) is a traditional medicine clinically used for the treatment of viral respiratory infection symptoms in most countries. We evaluated the effects of the herb on influenza virus replication in human lung cultured cells (A549) following the det...

ویروس موزائیک زرد کدو (zucchini yellow mosaic virus)، یکی از اعضاء جنس پوتی ویروس بوده و باعث کاهش قابل توجهی در کدوئیان در مناطق مختلف جهان می شود. ویروس موزائیک کدو (squash mosaic virus) باعث ایجاد موزائیک رگبرگ روشنی در خربزه می شود و عضو جنس کوموویروس است. به منظور تعیین شناسایی ویروس موزائیک زرد کدو و ویروس موزائیک کدو در استان های خراسان رضوی، شمالی و جنوبی در تابستان و پائیز 1388 و 1...

BK virus-associated hemorrhagic cystitis (HC) is frequent in patients undergoing bone marrow transplantation, but it rarely occurs among other immunosuppressed patients particularly in those who are receiving chemotherapy for hematologic malignancies. Herein, we report three children with malignancies suffering from hemorrhagic cystitis due to BK virus infection who were successfully improved. ...

objective: monitoring of influenza virus shedding and optimization of multiplicities of infection (moi) is important in the investigation of a virus one step growth cycle and for obtaining a high yield of virus in vaccine development and conventional basic diagnostic methods. however, eluted infectious viruses may still be present immediately after virus inoculation and when cells are washed fo...

Previous studies have shown antiviral effect of Echinacea and elderberry preparations against human influenza viruses in vitro. To investigate the in vivo antiviral effect of these herbs on avian H9N2 influenza virus, amantadine and two standardized commercial extracts of Echinacea purpurea (EF) and Sambucus nigra (SAM) were used in broiler chickens infected with H9N2 strain of the virus. EF, S...
