Insights

The Filoviridae family includes filamentous viruses like Ebola, some pathogenic to humans and others infecting bats. This report summarizes the International Committee on Taxonomy of Viruses findings on this viral family.

Area of Science:

  • Virology
  • Microbiology
  • Taxonomy

Background:

  • Filoviridae are enveloped viruses with filamentous virions.
  • They possess linear, non-segmented, negative-sense RNA genomes (15-19 kb).
  • Some filoviruses, like Ebola virus, are highly virulent human pathogens.

Purpose of the Study:

  • To summarize the International Committee on Taxonomy of Viruses (ICTV) report on the Filoviridae family.
  • To provide an updated taxonomic overview of Filoviridae.
  • To highlight known and unknown hosts of filoviruses.

Main Methods:

  • Review and synthesis of the ICTV Filoviridae Study Group's findings.
  • Analysis of viral morphology, genome characteristics, and host associations.
  • Taxonomic classification based on established criteria.

Main Results:

  • Detailed description of the Filoviridae family's characteristics.
  • Identification of pathogenic filoviruses and their hosts, including bats.
  • Clarification of taxonomic relationships within the family.

Conclusions:

  • The ICTV report provides a comprehensive taxonomic framework for Filoviridae.
  • Understanding filovirus diversity and host range is crucial for public health.
  • Ongoing research is needed to identify hosts for understudied filoviruses.

Taxonomy01:31

Taxonomy

Taxonomy is the science of defining and naming groups of biological organisms based on shared characteristics. It uses a hierarchy of increasingly inclusive categories with Latin names. The smallest units of taxonomy, species and genus, are used to assign a formal, taxonomic name to each species in a system. This classification system, referred to as binomial nomenclature, was formalized by Carolus Linnaeus in the 18th century.

Nursing Interventions I: Taxonomy of Nursing Interventions

Nursing interventions are chosen as part of the planning process to achieve patient outcomes. Once nursing diagnoses are determined, the goals and outcomes are specified, then the nursing interventions are selected and individualized according to the patient's situation.
A nursing intervention is a treatment or action based on scientific concepts and knowledge from the nursing, behavioral, and physical sciences. Identifying and prioritizing nursing interventions based on the desired outcome...

Ribosome Profiling02:24

Ribosome Profiling

Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.
The technique...
