Viral Recombination00:57

Viral Recombination

25.8K
Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

Symbiosis00:58

Symbiosis

38.8K
Symbiotic relationships are long-term, close interactions between individuals of different species that affect the distribution and abundance of those species. When a relationship is beneficial to both species, this is called mutualism. When the relationship is beneficial to one species but neither beneficial nor harmful to the other species, this is called commensalism. When one organism is harmed to benefit another, the relationship is known as parasitism. These types of relationships often...

Asexual Reproduction

38.4K
Asexual reproduction allows plants to reproduce without growing flowers, attracting pollinators, or dispersing seeds. Offspring are genetically identical to the parent and produced without the fusion of male and female gametes.

Infection01:20

Infection

14.7K
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Diversity of Protists I

2.3K
Excavata is a diverse group of protists that includes both chemoorganotrophic and phototrophic species, with some thriving in anaerobic environments. Among the key groups within Excavata are diplomonads and parabasalids, which are flagellated protists that lack mitochondria and chloroplasts. These microorganisms typically inhabit anoxic environments, such as the intestines of animals, where they exist either symbiotically or as parasites, relying on fermentation for energy production. Some...

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...

Resumen
Este resumen es generado por máquina.

Las bacterias Wolbachia que inducen la partenogénesis, transmitidas verticalmente, también pueden propagarse horizontalmente entre las larvas de avispa. Esta transferencia inesperada tiene un impacto en la coevolución del huésped Wolbachia.

Área de la Ciencia:

  • Microbiología Microbiología.
  • Biología evolutiva Biología evolutiva.
  • Entomología Entomología.

Sus antecedentes:

  • Wolbachia son parásitos reproductivos en insectos, que inducen la partenogénesis en las hembras infectadas.
  • La transmisión vertical (de madre a cría) es la principal vía conocida para la propagación de Wolbachia.
  • Los machos son considerados callejones sin salida para la transmisión vertical de estas bacterias.

Objetivo del estudio:

  • Investigar rutas de transmisión alternativas para las Wolbachia que inducen la partenogénesis.
  • Para determinar la frecuencia y la importancia de la transferencia horizontal de Wolbachia.
  • Para entender las implicaciones para la coevolución Wolbachia-anfitrión.

Principales métodos:

  • Estudios observacionales sobre las larvas de avispa que comparten fuentes de alimentos comunes.
  • Análisis microscópicos y genéticos para detectar la presencia y transferencia de Wolbachia.
  • Seguimiento de la transmisión vertical de Wolbachia adquirida horizontalmente.

Principales resultados:

  • Se observó una transmisión horizontal frecuente de Wolbachia entre larvas de avispas no infectadas e infectadas.
  • La transferencia horizontal se produjo a través de fuentes compartidas de alimento para larvas.
  • Los Wolbachia transferidos se transmitieron con éxito a las generaciones posteriores verticalmente.

Conclusiones:

  • La transmisión horizontal es una ruta significativa y natural para la propagación de Wolbachia dentro de las poblaciones de avispas.
  • Este hallazgo desafía el enfoque exclusivo en la transmisión vertical.
  • La transferencia horizontal frecuente tiene implicaciones cruciales para la dinámica coevolucionaria entre Wolbachia y sus anfitriones.
