introduction: tt virus (ttv) is an unenveloped single-stranded circular dna virus. sensitive pcr (polymerase chain reaction) methods with primers designed for very conserved regions of the viral genome (utr) indicate high prevalence (> 90%) of ttv infection in general population of many countries world-wide. although there has been no evidence of its relation to any liver or other specific dise...
Widespread occurrence of H9N2 low pathogenic avian influenza (LPAI) viruses in many Asian countriesduring the past decade has resulted in the need for evaluation of the pathogenesis of H9N2 virus infection. In this study, tissue tropism and dissemination of A/Chicken/Iran/772/1998(H9N2) virus throughout the body of broiler chickens were investigated. The clinical signs, gross lesions and antibo...
Background: The main viral causes of acute respiratory diseases (ARDs) include influenza viruses A and B, respiratory syncytial virus (RSV), adenovirus (ADV), rhinovirus, and parainfluenza viruses (PIV). This study aimed to investigate the prevalence of respiratory RSV, ADV and rhinovirus in patients with flu-like symptoms admitted to Mazandaran province health centers in north of Iran. Metho...
Background: The human T-cell lymphotropic virus type I is the first retrovirus idenfied in humans. The virus has been associated with adult T-cell leukemia/lymphoma, human T-lymphotropic virus type I, myelopathy/tropical spasc paraparesis, uveis, arthris, pulmonary lymphocyc alveolis, keratoconjuncvis sicca, and infecous dermas. Human T-lymphotropic virus type Iis endemic in Japan...
چکیده در سال 2005 دو ویروس تک رشته ای حلقوی در سرم بیمارانی با سندرم عفونی ویروسی حاد برای اولین بار کشف شدند و با در نظر گرفتن اندازه dna ژنومی که کوچکتر ازtorque teno virus(ttv) و بزرگتر از torque teno mini virus(ttmv) بودند، تحت عنوانsmall anellovirus1(sav1) وsmall anellovirus2(sav2) نامگذاری گردیدند و آن را در جنس طبقه بندی نشده از خانواده آنلوویریده قرار دادند. درسال 2007، ویروسtorque ten...
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 vi...
Abstract Background and Objectives Clinical features of SARS-COV-2 virus include fever, headache, cough, sore throat, and shortness of breath, and in severe forms it leads to disseminated intravascular coagulation, septic shock, and ultimately death. Excessive secretion of proinflammatory cytokines such as TNF-α, IL-6, and IL-1 leads to cytokine storms in this disease. The emergence of new va...
Introduction: The most common mode of rabies virus transmission is through a bite wound or contact of broken skin with saliva of a rabid animal. Various other routes of virus transmission include exposure of mucous membranes (i.e. eyes, nose, and mouth) to infected saliva of a rabid animal, aerosol transmission, and corneal transplantation. Laboratory workers during work with rabies virus and v...
