In medicine, public health, and biology, transmission is the passing of a pathogen causing communicable disease from an infected host individual or group to a particular individual or group, regardless of whether the other individual was previously infected. [ 1 ] The term strictly refers to the transmission of microorganisms directly from one ...
Transduction is the process by which foreign DNA is introduced into a cell by a virus or viral vector. [1] An example is the viral transfer of DNA from one bacterium to another and hence an example of horizontal gene transfer. [2] Transduction does not require physical contact between the cell donating the DNA and the cell receiving the DNA ...
Cell–cell interaction. Cell–cell interaction refers to the direct interactions between cell surfaces that play a crucial role in the development and function of multicellular organisms. These interactions allow cells to communicate with each other in response to changes in their microenvironment. This ability to send and receive signals is ...
A contagious disease is an infectious disease that is readily spread (that is, communicated) by transmission of a pathogen through contact (direct or indirect) with an infected person. [ 1] A disease is often known to be contagious before medical science discovers its causative agent. Koch's postulates, which were published at the end of the ...
In Latin, fomes (genitive: fomitis, plural fomites, stem fomit-) is a third-declension T-stem noun. Such nouns, like miles/militis or comes/comitis, typically lose their T (thereby becoming a syllable shorter) in the nominative singular, but retain it in all other cases. In languages derived from Latin, the French fomite, Italian fomite ...
In a scientific context, dissemination is defined as making projects results available to the scientific community, policy makers and industry – using scientific language prioritizing accuracy. [1] In terms of content, it covers the results of the research project, happens only when results are available and targets a specialist audience in ...
The goal is to stop the spread of a disease by finding and isolating cases. In public health, contact tracing is the process of identifying people who may have been exposed to an infected person ("contacts") and subsequent collection of further data to assess transmission. [ 1][ 2] By tracing the contacts of infected individuals, testing them ...
Bacterial conjugation is the transfer of genetic material between bacterial cells by direct cell-to-cell contact or by a bridge-like connection between two cells. [ 1] This takes place through a pilus. [ 2][full citation needed] It is a parasexual mode of reproduction in bacteria. A micrograph displaying Escherichia coli undergoing bacterial ...
