Identification and Characterization of Two Novel Viruses in Ocular Infections in Reindeer
نویسندگان
چکیده
A thorough understanding of virus diversity in wildlife provides epidemiological baseline information about pathogens. In this study, eye swab samples were obtained from semi-domesticated reindeer (Rangifertarandus tarandus) in Norway during an outbreak of infectious eye disease, possibly a very early stage of infectious keratoconjunctivitis (IKC). Large scale molecular virus screening, based on host nucleic acid depletion, sequence-independent amplification and next-generation sequencing of partially purified viral nucleic acid, revealed the presence of a new papillomavirus in 2 out of 8 eye swab samples and a new betaherpesvirus in 3 out of 8 eye swab samples collected from animals with clinical signs and not in similar samples in 9 animals without clinical signs. Whether either virus was responsible for causing the clinical signs or in any respect was associated to the disease condition remains to be determined.

Presence of Coronavirus, Enterovirus and Adenovirus in Municipal Wastewater as Indicators of the Prevalence of Associated Viral Infections in the Community
Background and purpose: Adenoviruses and enteroviruses as intestinal viruses are detected in wastewater. Fecal shedding of 2019 novel coronavirus (SARS-CoV-2) has been reported in some studies. Therefore, determining the presence of these viruses in wastewater is important to maintain public health and helps in predicting and preventing viral infections in a community. Materials and methods: I...
متن کاملMolecular Identification of Six Honeybee Viruses in Iranian Apiaries
The identification of honeybee viruses is of serious importance, particularly considering the lack of information on the natural incidence of viral infections in honeybee populations worldwide. Moreover, the global spread of Varroa destructor in honeybee colonies has a significant effect on the viral infection. In the present study, 160 samples of adult bee from apparently healthy colonies but ...

Infectious keratoconjunctivitis (IKC) is a painful, highly contagious ocular disease in sheep and goats. This study was carried out for identification and characterization of causative agent of ocular disease in a sheep flock consisting of 300 ewes in Mashhad, Iran. Several ocular swabs were taken from affected animals. The samples were pooled and processed in a laboratory for isolation of susp...
متن کاملMolecular and Clinical Characterization of 7 Iranian Patients with Severe Congenital Factor V Deficiency: Identification of 4 Novel Mutations
Background and Aims: Congenital factor V (FV) deficiency is a rare bleeding disorder with 1 in 1000000 persons in the general population. Individuals with FV activity <1% and very low FV antigen levels are characterized as severe FV deficient patients. Little data is available about the molecular basis of this bleeding disorder in Iran. Materials and Methods: We analyzed 7 unrelated Iranian FV...
