Background: The H9N2 subtype of the influenza virus, which is endemic in many regions of Iran, is considered as a candidate for future pandemics. In the present study, excretion time of the Iranian endemic influenza virus (H9N2 subtype) from the feces and pharyngeal secretions of laying chicken breeds was evaluated. Methods: This experimental study conducted at the Diagnostic Laboratory Scienc...
feline leukemia virus is a retrovirus of domestic cats that occurs throughout the world. persistent infection in the animals and persistently infected cats are at risk for developing of fatal diseases such as: lymphoma, leukemia, haematopoietic malignancies and anemia. in this study as the first time in iran the serologic prevalence of feline leukemia virus was determined with commercial elisa ...
Enzootic bovine leukosis (EBL) is known as bovine lymphosarcoma and normally affects the old cattle. EBL is caused by bovine leukemia virus (BLV), which is generally spread all around the world. This virus is transmitted via bovine blood products within and between cattle herds. Glycoprotein GP51 in the blood is responsible for cattle immune responses to BLV. This virus has been previously dete...
Background and purpose: Crimean Congo Hemorrhagic Fever (CCHF) is a dangerous viral zoonotic disease. Ticks are the main vector which transmit CCHF virus from livestock to human. The present study was done to provide a comprehensive database on major ticks in the CCHF virus transmission and their geographical dispersal in Iran. This would be of great benefit in planning for intelligent control ...
Infectious bursal disease virus (IBDV) in turkeys may result in immunosuppression, and inability of turkeys to resist nonpathogenic or less pathogenic organisms. A total number of 120 day-old commercial male turkeys were purchased and blood samples were collected from 20 day-old turkeys, remaining 100 were divided into four equal groups and kept in separated rooms. Groups 1 and 2 were infected ...
The detection methods for infectious bronchitis virus (IBV) are reviewed. Advantages and disadvantages of available techniques of IBV detection by virus isolation, antigen or genome detection, and serology are discussed. Factors of influence on the level of success in detection of IBV after a disease outbreak are discussed, as are the possibilities and dangers of strain classification by protec...
conclusions mp, flub and rsv are the principal contributors to ari in the hubei area, with mixed infections, typically of mp and flub, being the most common pathogens statistically significant between different age groups. background acute respiratory infection (ari) is one of the primary diseases that cause high morbidity and mortality to children especially in developing countries. ari can co...
Dengue virus serotype 2-positive plasma was applied to two indirect single-molecule arrays (Simoas) for the detection of anti-dengue virus IgG and IgM. The Simoas were 1,000 and 10,000 times more sensitive than enzyme-linked immunosorbent assays (ELISAs) for the detection of IgG and IgM, respectively. Using Simoas, serology may be used for the detection of dengue virus infection in the acute ph...
The aim of this study was to identify different virulence pathogens using Real-Time PCR method for rapid and accurate detection of common viral diseases including Infectious Hematopoietic Necrosis (IHN), Viral Hemorrhagic Septicemia (VHS) and Infectious Pancreatic Necrosis disease (IPN) in rainbow trout broodstock have been the main generation of reproductive populations maintained in the natio...
Background and Aims: Certification programs of plant propagating materials rely on faster, cheaper and more importantly sensitive and reliable methods for detection of systemic pathogens as indicated in national and/or international health standards of plant propagating materials. Reverse transcription-polymerase chain reaction (RT-PCR) has been documented as an alternative assay for certific...
