Infection01:20

Infection

13.4K
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...

Types of Genetic Transfer Between Organisms

31.4K
Genetic transfer occurs when genetic information is passed from one organism to another. It occurs via two mechanisms: vertical gene transfer and horizontal gene transfer. Vertical gene transfer occurs when genetic information is transferred from one generation to the next, which happens much more frequently than horizontal gene transfer. Both sexual and asexual reproduction are forms of vertical gene transfer, where one or more organisms pass some or all of their genome onto their progeny.

Symbiosis

37.9K
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...

Transduction01:16

Transduction

2.2K
Among the three main modes of HGT—transformation, conjugation, and transduction—transduction is unique in that it is mediated by bacteriophages, or bacterial viruses.Transduction occurs in two ways. Generalized transduction occurs during the lytic cycle of a bacteriophage infection. In this process, bacteriophages infect bacterial cells, replicate within them, and ultimately cause cell lysis, releasing newly assembled virions. Occasionally, random fragments of the bacterial genome...

Intracellular Movement of Viruses and Bacteria01:10

Intracellular Movement of Viruses and Bacteria

3.7K
Intracellular bacteria and viruses often comprise a group of highly infectious pathogens that can cause several diseases. Bacterial pathogens include those belonging to the genus Rickettsia responsible for conditions such as rocky mountain spotted fever and the Mediterranean spotted fever; Chlamydia, a genus responsible for a sexually transmitted disease; Coxiella burnetii, an agent responsible for Q fever. Viral pathogens include vaccinia—a poxvirus, and herpes simplex virus—a...

Area of Science:

  • Evolutionary Biology
  • Genetics
  • Theoretical Biology

Background:

  • The study of inheritance is expanding beyond DNA to include non-genetic factors.
  • Existing frameworks often focus on transmission direction (vertical, horizontal) and variation storage.
  • A unified conceptual framework is needed to integrate diverse transmission modes and their evolutionary impact.

Purpose of the Study:

  • To develop an inclusive evolutionary conceptual framework for tracing various forms of transmission.
  • To analyze the interplay between transmission dynamics and evolutionary dynamics.
  • To provide a basis for qualitative and quantitative analyses of transmission and evolution.

Main Methods:

  • Proposed three key distinctions for transmission analysis: two channels, two temporal dynamics (durability and residency), and two factor types (selectively relevant and neutral stable).
  • Developed a conceptual framework mapping transmission forms based on these distinctions.
  • Focused on building a framework rather than proposing a new inheritance model.

Main Results:

  • The framework integrates diverse transmission forms by considering their dynamical features across a continuous space.
  • It offers a comprehensive view of transmission, grounded in empirical observation and evolutionary theory.
  • The distinctions allow for mapping and analyzing different transmission tempos and modes.

Conclusions:

  • The proposed framework provides an inclusive conceptualization of transmission, essential for understanding evolutionary dynamics.
  • It facilitates the study of the interplay between the dynamics of evolution and multiple transmission forms.
  • This approach is crucial for advancing theoretical and empirical investigations in evolutionary biology.
