Sustained fecal-oral human-to-human transmission following a zoonotic event

Sustained fecal-oral human-to-human transmission following a zoonotic event | Viruses and Bioinformatics from Virology.uvic.ca | Scoop.it
Bacterial, viral and parasitic zoonotic pathogens that transmit via the fecal-oral route have a major impact on global health. However, the mechanisms underlying the emergence of such pathogens from the animal reservoir and their persistence in the human population are poorly understood. Here, we present a framework of human-to-human transmission of zoonotic pathogens that considers the factors relevant for fecal-oral human-to-human transmission route at the levels of host, pathogen, and environment. We discuss current data gaps and propose future research directions.

GMO - Common Science Space

GMO - Common Science Space | Viruses and Bioinformatics from Virology.uvic.ca | Scoop.it
It’s a good idea to look critically at any powerful new technology, and the creation of genetically-modified organisms, GMOs, is no exception. Like any new technology, it might have unanticipated, deleterious consequences that outweigh any benefit. Many criticisms of GMO have of course been raised, as a brief interrogation of the internet will show. But unfortunately,... Continue Reading

Intraspecies transmission of viruses: Human-to-human transmission

Infection of humans by viruses from animal hosts — so-called zoonoses — occur relatively frequently around the world. Examples over the last few decades include human infections caused by avian influenza A viruses of hemagglutinin subtypes H5, H6, H7, H9, and H10, swine influenza A viruses of subtypes H1 and H3, Hendra virus and Nipah virus, Severe Acute Respiratory Syndrome (SARS)-coronavirus and Middle East Respiratory Syndrome (MERS)-coronavirus, West-Nile virus, and Ebola virus. Fortunately, most zoonotic infections occur as isolated cases or small clusters, posing little risk to the public at large. However, some zoonotic infections may trigger local or regional outbreaks, spread to humans in various parts of the world, or even result in widespread global outbreaks known as pandemics.

Cross-species jumps may play unexpectedly big role in virus evolution: Comparing host and virus evolutionary trees reveals new insights into emergence of viral diseases

Cross-species jumps may play unexpectedly big role in virus evolution: Comparing host and virus evolutionary trees reveals new insights into emergence of viral diseases | Viruses and Bioinformatics from Virology.uvic.ca | Scoop.it
On occasion, a virus may jump from one host species to another and adapt to the new host. Such cross-species transmission happens more often than expected, according to new research, and it may play a much bigger role in virus evolution than previously thought.

All biology is computational biology

All biology is computational biology | Viruses and Bioinformatics from Virology.uvic.ca | Scoop.it
Here, I argue that computational thinking and techniques are so central to the quest of understanding life that today all biology is computational biology. Computational biology brings order into our understanding of life, it makes biological concepts rigorous and testable, and it provides a reference map that holds together individual insights. The next modern synthesis in biology will be driven by mathematical, statistical, and computational methods being absorbed into mainstream biological training, turning biology into a quantitative science.

The sense behind retroviral anti-sense transcription

Retroviruses are known to rely extensively on the expression of viral proteins from the sense proviral genomic strand. Yet, the production of regulatory retroviral proteins from antisense-encoded viral genes is gaining research attention, due to their clinical significance. This report will discuss what is known about antisense transcription in Retroviridae, and provide new information about antisense transcriptional regulation through a comparison of Human Immunodeficiency Virus (HIV), Human T-cell Lymphotrophic Virus (HTLV-1) and endogenous retrovirus-K (ERVK) long terminal repeats (LTRs). We will attempt to demonstrate that the potential for antisense transcription is more widespread within retroviruses than has been previously appreciated, with this feature being the rule, rather than the exception.

The blood DNA virome in 8,000 humans

The blood DNA virome in 8,000 humans | Viruses and Bioinformatics from Virology.uvic.ca | Scoop.it
Author summary Novel sequencing technologies offer insight into the virome in human samples. Here, we identify the viral DNA sequences in blood of over 8,000 individuals undergoing whole genome sequencing. This approach serves to identify 94 viruses; however, many are shown to reflect widespread DNA contamination of commercial reagents or of environmental origin. While this represents a significant limitation to reliably identify novel viruses infecting humans, we could confidently detect sequences and quantify abundance of 19 human viruses in 42% of individuals. Ancestry, sex, and age were important determinants of viral prevalence. This large study calls attention on the challenge of interpreting next generation sequencing data for the identification of novel viruses. However, it serves to categorize the abundance of human DNA viruses using an unbiased technique.

Dramatic evolution within human genome may have been caused by malaria parasite

Dramatic evolution within human genome may have been caused by malaria parasite | Viruses and Bioinformatics from Virology.uvic.ca | Scoop.it

A genetic mutation that protects people from a common form of malaria spread like wildfire in sub-Saharan Africa about 42,000 years ago, according to a new study. Today, it’s nearly impossible to find somebody from this region who doesn’t have it. That makes the mutation one of the swiftest, strongest changes to the human genome yet seen—though it remains a mystery why this particular disease sparked such a dramatic evolutionary response.

Mimivirus: leading the way in the discovery of giant viruses of amoebae : Nature Reviews Microbiology : Nature Research

Mimivirus: leading the way in the discovery of giant viruses of amoebae : Nature Reviews Microbiology : Nature Research | Viruses and Bioinformatics from Virology.uvic.ca | Scoop.it
The accidental discovery of the giant virus of amoeba — Acanthamoeba polyphaga mimivirus (APMV; more commonly known as mimivirus) — in 2003 changed the field of virology. Viruses were previously defined by their submicroscopic size, which probably prevented the search for giant viruses, which are visible by light microscopy. Extended studies of giant viruses of amoebae revealed that they have genetic, proteomic and structural complexities that were not thought to exist among viruses and that are comparable to those of bacteria, archaea and small eukaryotes. The giant virus particles contain mRNA and more than 100 proteins, they have gene repertoires that are broader than those of other viruses and, notably, some encode translation components. The infection cycles of giant viruses of amoebae involve virus entry by amoebal phagocytosis and replication in viral factories. In addition, mimiviruses are infected by virophages, defend against them through the mimivirus virophage resistance element (MIMIVIRE) system and have a unique mobilome. Overall, giant viruses of amoebae, including mimiviruses, marseilleviruses, pandoraviruses, pithoviruses, faustoviruses and molliviruses, challenge the definition and classification of viruses, and have increasingly been detected in humans.

Protect this house: cytosolic sensing of viruses

Protect this house: cytosolic sensing of viruses | Viruses and Bioinformatics from Virology.uvic.ca | Scoop.it
The ability to recognize invading viral pathogens and to distinguish their components from those of the host cell is critical to initiate the innate immune response. The efficiency of this detection is an important factor in determining the susceptibility of the cell to viral infection. Innate sensing of viruses is, therefore, an indispensable step in the line of defense for cells and organisms. Recent discoveries have uncovered novel sensors of viral components and hallmarks of infection, as well as mechanisms by which cells discriminate between self and non-self. This review highlights the mechanisms used by cells to detect viral pathogens in the cytosol, and recent advances in the field of cytosolic sensing of viruses.

Human Rhinovirus Diversity and Evolution: How Strange the Change from Major to Minor

Rhinoviruses are the most common causes of the common cold. Their many distinct lineages fall into “major” and “minor” groups that use different cell surface receptors to enter host cells. Minor-group rhinoviruses are more immunogenic in laboratory studies, although their patterns of transmission and their cold symptoms are broadly similar to those of the major group. Here we present evolutionary evidence that minor-group viruses are also more immunogenic in humans. A key finding is that rates of amino acid substitutions at exposed sites in the capsid proteins VP2, VP3, and VP1 tend to be elevated in minor-group relative to major-group viruses, while rates at buried sites show no consistent differences. A reanalysis of historical virus watch data also indicates a higher immunogenicity of minor-group viruses, consistent with our findings about evolutionary rates at amino acid positions most directly exposed to immune surveillance. The increased immunogenicity and speed of evolution in minor-group lineages may contribute to the very large numbers of rhinovirus serotypes that coexist while differing in virulence.
