Insights

Virus-like particles were detected in healthy Peregrinus maidis (corn leafhopper) in Venezuela, suggesting a latent infection. These particles were absent in Hawaiian insects, indicating a potential geographic or strain-specific viral presence.

Area of Science:

  • Entomology
  • Virology
  • Insect Pathology

Background:

  • Virus-like particles (VLPs) can cause latent infections in insect vectors.
  • Peregrinus maidis is a significant agricultural pest, particularly in maize production.

Purpose of the Study:

  • To investigate the presence and characteristics of virus-like particles in Peregrinus maidis.
  • To determine the potential transmission and origin of these particles.

Main Methods:

  • Microscopic examination of P. maidis tissues from Venezuela and Hawaii.
  • Transmission studies involving injection of insect homogenates.
  • Observation of insect feeding behavior on contaminated plant material.

Main Results:

  • VLPs were identified in various tissues of Venezuelan P. maidis, including salivary glands, intestine, and hemolymph.
  • Particles were absent in Hawaiian P. maidis but appeared after injection with Venezuelan insect material.
  • Polygonal particles (54 +/- 9 mmu) with distinct envelopes and cores were observed.

Conclusions:

  • The findings suggest a latent viral infection in Venezuelan P. maidis.
  • The virus is likely specific to certain P. maidis populations and not transmitted via plant surfaces.

Human Virome01:26

Human Virome

The human body harbors a vast and diverse viral community known as the human virome. The virome includes bacteriophages that infect bacteria, and eukaryotic viruses that infect human cells. Transient dietary and environmental viruses also contribute to this dynamic ecosystem. Estimates suggest the human body may contain on the order of 10¹³ viral particles, though abundance varies widely by body site and detection method.Comprehensive characterization of the virome has become possible only with...
Subviral Agents01:29

Subviral Agents

Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...
