Molecular Evolution of Viruses
… Our goal was to study molecular evolution of viruses with special reference to Influenza A Virus.</p> <p>The recent Influenza A/H1N1(2009) outbreak has been the focus of intense research because of its high level of infectivity across the globe. Analysis of nucleotide sequence polymorphism in …

Battle of the Viruses: Aripo Virus Induced Superinfection Exclusion of Mosquito-borne Viruses
Flaviviruses are a single-stranded, positive sense, RNA virus that affect around 400 million people annually. Flaviviruses are transmitted by arthropod vectors, the most common vector being the mosquito. Currently, many mosquito control strategies are in use, these control strategies are diverse in …

Predicting motif mimicry in viruses
… data can be used to study molecular mimicry in viruses and to discover novel SLiMs. An in-silico peptide exchange approach was developed and applied to provide additional validation of predicted mimicry candidates. Despite limitations of this technique in large-scale validation of predicted …

Surveillance of Emerging Livestock Viruses
<p>Accurate and rapid diagnostic tests are essential for the management and control of emerging infectious diseases. Therefore, the overall goals of studies presented in this dissertation were to provide improved diagnostic and surveillance capabilities for several emerging viral diseases impacting …

Human adaptation of avian influenza viruses
Human adaptation of avian influenza viruses pose an enormous public health challenge as the human population is predominantly naive to avian influenza antigens. As such, constant surveillance is needed to monitor the circulating avian strains. Of particular importance are strains belonging to H5N1, …

Persistent RNA Viruses of Common Bean (Phaseolus vulgaris): Distribution and Interaction with the Host and Acute Plant Viruses
… can be infected with acute and persistent plant viruses. A modified dsRNA extraction method was developed and used in this study. The method was fast, economic, versatile, and required relatively small amounts of desiccated plant tissue. The method was successfully used to extract dsRNAs from …

Strategies for Oncogenesis by Avian Leukosis Viruses
<p>The mechanism of oncogenesis by avian leukosis viruses (ALVs) was examined. ALVs are slowly transforming RNA tumor viruses that do not transform cells in tissue culture and that cause neoplastic disease only after a latent period of 4-12 months. ALVs generally induce widely disseminating B cell …

Decontamination from Black Viruses Using Parallel Strategies
… problem of decontaminating networks from black viruses (BVs) with a team of mobile agents, using parallel strategies. The BV is a harmful process whose initial location is unknown a priori. It destroys any agent arriving at the network site where it resides and, once triggered, it spreads to all …

Study of viruses isolated in the tropics
… on studies of the properties and epidemiology of viruses isolated in Africa. Investigations of the epidemiology of yellow fever and of new methods of vaccinating against it are described in the first series of papers. These yellow fever studies led incidentally to the recovery of several …

Disrupting insect-mediated transmission of plant viruses
Many plant viruses are vectored by aphids in the non-persistent mode, in which virus particles are transported on these insects’ specialised piercing mouthparts (stylets). Virus infection can change plant-vector interactions and it is thought that this may accelerate virus transmission. To better …

Biophysics of Helices: Devices, Bacteria and Viruses
… world of artificial microswimmers, bacteria and viruses is that of a helix. The intriguingly different physics at play at the small scale level make it necessary for bacteria to employ swimming strategies different from our everyday experience, such as the rotation of a helical filament. …

Viruses of Heliothis armigera (Hübner) (Lepidoptera : Noctuidae)
… simultaneously infected with several insect viruses: nuclear polyhedrosis virus (NPV), granulosis virus (GV), and cytoplasmic polyhedrosis virus (CPV). Both NPV and GV have been previously studied because of their ready availability and their potential use in pest control. However, there have …

Novel acyclic nucleotide phosphonates against RNA viruses
Acyclic nucleotide phosphonates (ANPs) have been used for years as successful anti-viral agents against diseases such as HIV/AIDS and hepatitis while the drug ribavirin is one of the only drugs available for the treatment of RNA-viral infections which mainly affect the developing world. The large …

Characterisation of two aphid picorna-like viruses
… distantly related to two insect picornaviruses, cricket paralysis virus (CrPV) and Drosophila C virus. No nucleic acid homology was detected between ALPV cDNA and CrPV by dot-blot hybridization. ALPV is serologically unrelated to seven other insect picornalike viruses. RhPV is …
