A detection system based on a multiplex reverse transcription (RT) polymerase chain reaction (PCR) was developed to simultaneously identify multiple viruses in the lily plant. The most common viruses infecting lily plants are the cucumber mosaic virus (CMV), lily mottle virus (LMoV), lily symptomless virus (LSV). Leaf samples were collected at lily-cultivation facilities located in the Kangwon ...
Background and Aims: Influenza A virus infects birds and some mammalian including human. H1 and H3 subtypes are circulated in both human and birds’ population. To determine the prevalence of the mentioned subtypes in birds, different captive bird species in Tehran zoo, and affiliated centers in Tehran were investigated for virus infection. Methods: In this study, Between November 2008 and...
Introduction: Contamination with high-risk human papillomavirus (HPV) is one of the most important risk factors for developing cervix cancer. Since there is no possibility of detecting the virus and its subtypes by using current biochemical and serological methods and cell culture, the molecular methods such as multiplex PCR have particular importance in accurate, early and definite diagnosis o...
Introduction: Multiple sclerosis (MS) is an inflammatory disease of the central nervous system (CNS). It is an Auto immune disease whose cause is still unknown though some factors can be named as its cause such as genetics, geographic element and viral agents. HSV is among the infection agents that may be involved in pathogenesis of MS. The aim of this study was to use a new technique called lo...
To improve commercial grapevine cultivars, it is necessary to apply such methods that by cultivation of a certain number of vines in a certain area, higher yield could be harvested. To achieve such a goal, healthy stocks with resistant to pests and diseases, high fructification and high quality of vines are needed. All these properties can be obtained successfully through clonal selection. Viti...
BACKGROUND: Equine herpes virus-1 (EHV-1) is a major cause of economic loss in horse industry and is well recognized as a cause of abortion, respiratory disease, neurologic disorders and death of neonatal foals.OBJECTIVES: The aim of this study was to evaluate the frequency of EHV-1 in horses with clinical signs and/or history associated with this virus from four provinces of Iran (Golest...
Monitoring of poultry, including domestic ducks, for avian influenza (AI) virus has increased considerably in recent years. However, the current methods validated for the diagnosis and detection of AI virus infection in chickens and turkeys have not been evaluated for performance with samples collected from domestic ducks. In order to ensure that methods for the detection of AI virus or AI viru...
Viral integration into the human genome upon infection is an important risk factor for various human malignancies. We developed viral integration site detection tool called Virus-Clip, which makes use of information extracted from soft-clipped sequencing reads to identify exact positions of human and virus breakpoints of integration events. With initial read alignment to virus reference genome ...
We evaluated the added value of collecting both nasal and oropharyngeal swabs, compared with collection of nasal swabs alone, for detection of common respiratory viruses by reverse transcription-polymerase chain reaction in hospitalized children aged <10 years. Nasal swabs had equal or greater sensitivity than oropharyngeal swabs for detection of respiratory syncytial virus, adenovirus, human m...
Background and Aims: Finding prevalence of chicken anemia virus (CAV) infection in native chickens is necessary to avoid transmission of infection to commercial flocks. In this paper we attempt to describe molecular detection of chicken anemia virus in native Larry-breed chickens in Chaharmahal-va-Bakhtiyari province in Iran for the first time. Materials and Methods: Blood samples were collect...
