This is a report of the first serological survey of influenza C virus in Iran, performed during a one year period (March 1997-May 1998). This study was accomplished in the National Influenza Center-Division of Virology in Tehran University of Medical Scinces. 1080 samples of serum (689 samples from Tehran and 391 samples from other provinces) were assayed for the presence of antibodies against ...
The purpose of this paper is to provides general information about avian influenza (bird flu) and specific information about one type of bird flu, called avian influenza A (H5N1), that has caused infections in birds in Asia and Europe and in human in Asia. The main materials in this report are based on the World Health Organization (WHO) , world organization for animal health (OIE) , food and a...
Background and purpose: Influenza is a seasonal respiratory illness that affects all age groups and causes excess mortality. Identifying the clinical manifestations and complications could be of great value in preventing the flue pandemic. Recent H1N1 pandemic is associated with some unusual findings such as thrombocytopenia, leukopenia, and lymphopenia which are not reported in other types of ...
Background and Objective: Adamantanes, amantadine, and rimantadine have been used for many years for prevention and treatment of influenza virus A infections. These drugs are influenza virus M2 protein inhibitors and some amino acids substitutions in transmembrane portion of this protein cause resistance to them. This study was done for survey of adamantane resistance related nucleotide sequenc...
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...
background and aims: influenza is one of the main respiratory infections of humans, responsible for 300,000–500,000 annual deaths world-wide. vaccination is one of the best ways to prevent infections including influenza. influenza virosomes are virus-like particles, which retain the cell binding and membrane fusion properties of the native virus, but lack the ribonucleoprotein (rnp). a virosoma...
background influenza can causes morbidity and mortality that are greatly enhanced in patients with underlying chronic diseases such as cirrhotic patients. this study was performed to assess the immunogenicity of influenza vaccination in patients with cirrhosis and inactive carriers of hepatitis b virus infection. methods in this clinical study 93 enrolled subjects divided into 3 groups: cirrhot...
background: the pandemic and regional influenza outbreaks resulting from antigenic variation of influenza viruses have been the subject of numerous studies which are crucial to the preparation of the vaccine. frequent global winter outbreaks of influenza viruses require a constant surveillance of emerging influenza variants in order to develop efficient influenza vaccine. methods: this study ...
avian influenza is one of the most important diseases in avian industry, which also threats human population. thus, vaccination is necessary for controlling this viral disease. in this study, killed vaccine of avian influenza subtype h9n2 and formalin solution (for virus inactivation) were used. it is necessary to study the effect of different factors such as formalin concentration, as well as ...
objective this is the first report of cns involvement by the new influenza virus (influenza a [h1n1]) in iran. the patient was a 10-year-old boy with chief complaints of fever, malaise, and cranial nerve involvement, resulting in respiratory muscle paralysis and intubation. this shows that the new influenza virus, as well as the seasonal flu, can cause neurologic complications; however, the sev...
