Within the last 20 years, however, the revolution of modern biotechnology has led to an explosive increase in our knowledge of viruses and their interactions with their hosts. Virology, the study of viruses, includes many aspects: the molecular biology of virus replication; the structure of ...

first, followed by retroid elements, and DNA viruses. The Virus World concept is predicated on a model of early evolution whereby emergence of substantial genetic diversity antedates the advent of full-fledged cells, allowing for extensive gene mixing at this early stage of evolution. We outline ...
A. The soluble form of human respiratory syncytial virus attachment protein differs from the membrane-bound form in its oligomeric state but is still capable of binding to cell surface proteoglycans. J. Virol. 78, 3524–3532 (2004). Article CAS PubMed PubMed Central Google Scholar Krusat, ...
(DENV) that is known to cause the full range of DF diseases worldwide comprises four independent but antigen-related serotypes (DENV1-4) and belongs to the genusflavivirusof the familyFlaviviridae[5]. The virus is a positive sense single-stranded encapsulated RNA virus and comprises virus-...
Full size image Infection prevalence in hatchery and sea-based juvenile lobsters Intranuclear inclusions were observed in 12.72% of all samples processed for histology (145/1140) across the two-year sampling period. In sea-based lobsters the prevalence of intranuclear inclusions was highest at 39 wee...
Full size image The model exhibits annual winter epidemics in temperate regions and less periodic epidemics in the tropics (Figure 2A). Across replicate simulations, we observe average yearly attack rates of 6.8% in temperate regions and rates of 7.1% in the tropics, comparable with estimated atta...
Full size image Despite the clinical differences observed between both groups, no statistical differences were found in the survival analysis. In this respect, the survival of CSFV-ASFV infected animals (Group A) was equal to the pestivirus-free-wild boars from Group B. Only animal 4 in Group...
In subject area:Biochemistry, Genetics and Molecular Biology HIV-associated neurocognitive disorders (HAND) is a term used to describe a form of a subcortical neurologic condition characterized by cognitive (i.e., striato-frontal profile of impairment), behavior changes (e.g., apathy; disinhib...
