Viruses of Helminthosporium (Cochlioblus) victoriae.
The enigma of the transmissible disease of Helminthosporium victoriae has almost been resolved. Diseased isolates are doubly infected with two distinct viruses, the victorivirus Helminthosporium victoriae virus 190S and the chrysovirus HvV145S. Mixed infection, however, is not required for disease development. DNA transformation experiments and transfection assays using purified HvV190S virions...
متن کاملElectron Cryo-Microscopy Studies of Helminthosporium victoriae Virus 190S.
The parasitic nature of viruses is a source of intense interest owing to the wide variety of potential hosts, which include humans, livestock, fungi, agricultural crops, as well as many others [1]. Viruses are differentiated by variations in properties such as size, capsid morphology, genomic composition, replication strategy, and host target [1, 2]. The family Totiviridae of dsRNA viruses is c...
متن کاملConservative Transcription of Helminthosporium victoriae 190S Virus Double-stranded RNA in vitro
In in vitro reactions, the Helminthosporium victoriae 190S virus-associated RNA polymerase catalysed the synthesis and release of full-length ssRNA transcripts of genomic dsRNA. The transcriptase activity, which was dependent on virus concentration, required all four nucleoside triphosphates and magnesium ions. In reaction mixtures containing [3 H]UTP, 99-0 ~ to 99.5 ~o of the incorporated labe...
متن کاملDevelopment and characterization of novel chimeric monoclonal antibodies for broad spectrum neutralization of rabies virus
Current post-exposure prophylaxis for rabies virus infection has several limitations in terms of supply, cost, safety, and efficacy. Attempts to replace human or equine rabies immune globulins (HRIG or ERIG) have been made by several companies and institutes. We developed potent monoclonal antibodies to neutralize a broad spectrum of rabies viruses by screening hybridomas received from the U.S....
متن کاملApplying conserved peptides of NS1 Protein of avian influenza virus to differentiate infected from vaccinated chickens
Avian influenza (AI) is a highly contagious disease in poultry and outbreaks can have dramatic economic and health implications. For effective disease surveillance, rapid and sensitive assays are needed to detect antibodies against AI virus (AIV) proteins. In order to support eradication efforts of avian influenza (AI) infections in poultry, the implementation of “DIVA” vaccination strategies, ...
