REASSORTANT VIRUSES Meaning and
Definition
-
Reassortant viruses are a type of viral strain that results from the reassortment process in which two or more different strains of the same virus or closely related viruses exchange genetic material to form a new combination. This phenomenon commonly occurs in viruses that have segmented genomes, such as influenza viruses.
During reassortment, the genetic material, usually in the form of RNA segments, from different parent strains is mixed and matched to form a new combination of genes. This process can occur when two viruses infect the same host cell simultaneously. The resulting reassortant viruses carry genetic traits from both parent strains and exhibit a new combination of their characteristics, leading to the emergence of a novel viral strain.
Reassortant viruses have significant implications in the field of virology as they can lead to the emergence of new strains with altered virulence, transmission capability, or antigenicity. This can potentially result in outbreaks or pandemics, as seen in the case of influenza, where reassortment events between animal and human strains have given rise to novel, highly virulent strains capable of spreading rapidly in the human population.
Understanding the genetic makeup and characteristics of reassortant viruses is essential for surveillance and effective management of viral diseases. Monitoring these viruses can help identify potential threats, develop targeted interventions, and design appropriate strategies for vaccine development to mitigate the impact of emerging viral strains.

Etymology of REASSORTANT VIRUSES
The word "reassortant" is derived from the verb "reassort", which means to recombine or rearrange different elements to create a new combination. In the context of viruses, "reassortment" refers to the genetic exchange or shuffling of genetic material (e.g., RNA segments) between different virus strains that infect the same host cell. This process results in the formation of new viral strains that possess a combination of genetic features from the parent strains.
The term "reassortant viruses" is a compound word that combines "reassortant" with "viruses". It is used to describe the newly formed virus strains resulting from reassortment events. These reassortant viruses often have the potential to exhibit altered characteristics, such as enhanced transmissibility or pathogenicity, compared to the parent strains.
