Taxonomy

90.1K
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

3.9K
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

4.2K
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...

Area of Science:

  • Virology
  • Animal Pathology
  • Taxonomy

Background:

  • Asfarviridae is a viral family with one species, African swine fever virus (ASFV).
  • ASFV isolates possess linear double-stranded DNA (dsDNA) genomes ranging from 170-194 kilobase pairs (kbp).
  • ASFV virions feature a complex structure including an internal core, lipid membrane, icosahedral capsid, and outer lipid envelope.

Purpose of the Study:

  • To summarize the International Committee on Taxonomy of Viruses (ICTV) report on Asfarviridae taxonomy.
  • To provide an overview of African swine fever virus characteristics and epidemiology.

Main Methods:

  • Review and summarization of the official ICTV report on Asfarviridae.
  • Compilation of data on ASFV genome, virion structure, and disease transmission.

Main Results:

  • ASFV infection leads to acute hemorrhagic fever in domestic pigs and wild boar.
  • Transmission occurs through direct contact, ingestion, or via Ornithodoros ticks.
  • Indigenous pigs in Africa serve as reservoirs, with periodic introductions into Europe.

Conclusions:

  • ASFV is a significant pathogen with complex structural and epidemiological characteristics.
  • Understanding ASFV taxonomy and transmission is crucial for disease control and prevention efforts.
