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...
in this study, the pathogenicity of a/ch/it/5093/1999 h7n1 which had been isolated from chicken during the outbreak in italy was assessed in chicken by experimental infection virus. ten spf chickens of four week-old were inoculated with this virus, and five chickens were inoculated with uninfected allantoic fluid. for determination of virus shedding, oropharyngeal and cloacal swabs were taken f...

Introduction: Hepatitis D virus (HDV) is a 35 nm in diameter agent that depends on hepatitis B surface antigen in order to proliferate and accumulate. Infection with delta agent can occur spontaneously with hepatitis B virus infection and it cause acute hepatitis or develop as secondary infection in the patients with hepatitis B. Hepatitis D virus (HDV) has several genotypes based on genome seq...
The study of dispersion of alfalfa mosaic virus (ALMV) infection based on DAS-ELISA indicated that the fields of Alfalfa, potatoes and tomatoes from Chenaran, Ghochan, Shirvan, Mashhad, Neishaboor and Torbat Heydarieh were infected with the virus. The Statistical analysis indicated that the amount of infection did not differ in the surveyed regions and total mean of infection was 53 percent. Th...
