Genetic reassortment of mammalian reoviruses in mice [PDF]

Journal of Virology, 1985
Reassortments between type 1 (Lang) and type 3 (Dearing) reoviruses were isolated from suckling mice infected perorally with an inoculum containing both type 1 and type 3 viruses. A total of five distinct reassortants (designated as E1 through E5) were isolated from animals during the course of the experiment.

Avian influenza overview March–May 2026

EFSA Journal, Volume 24, Issue 7, July 2026.
Abstract Between 28 February and 4 June 2026, 949 highly pathogenic avian influenza (HPAI) A(H5) virus detections were reported in domestic (186) and wild (763) birds in 30 countries in Europe. The downward trend in the number of detections observed at the end of the previous reporting period continued and is expected to persist throughout the summer ...

VIRAPOPS2 supports the influenza virus reassortments [PDF]

Source Code for Biology and Medicine, 2014
For over 400 years, due to the reassortment of their segmented genomes, influenza viruses evolve extremely quickly and cause devastating epidemics. This reassortment arises because two flu viruses can infect the same cell and therefore the new virions' genomes will be composed of segment reassortments of the two parental strains.

Assessing the Impact of Rotavirus Vaccination in Iranian Children Under Five: An Agent‐Based Modelling Approach

Health Science Reports, Volume 9, Issue 6, June 2026.
ABSTRACT Background and Aims Rotavirus is a leading cause of severe diarrhoeal disease in young children worldwide. In 2024, Iran introduced the pentavalent oral vaccine Rotasiil® into its national immunization program. This study aimed to estimate its potential epidemiological impact using an agent‐based modeling (ABM) approach.

Intrahost Dynamics of Influenza Virus Reassortment [PDF]

Journal of Virology, 2014
ABSTRACT The segmented nature of the influenza virus genome allows reassortment between coinfecting viruses. This process of genetic exchange vastly increases the diversity of circulating influenza viruses. The importance of reassortment to public health is clear from its role in the emergence of a number of epidemiologically ...

In vitro reassortment between endemic H1N2 and 2009 H1N1 pandemic swine influenza viruses generates attenuated viruses. [PDF]

PLoS ONE, 2012
The pandemic H1N1 (pH1N1) influenza virus was first reported in humans in the spring of 2009 and soon thereafter was identified in numerous species, including swine. Reassortant viruses, presumably arising from the co-infection of pH1N1 and endemic swine

Evolutionary and transmission dynamics of reassortant H5N1 influenza virus in Indonesia. [PDF]

PLoS Pathogens, 2008
H5N1 highly pathogenic avian influenza (HPAI) viruses have seriously affected the Asian poultry industry since their recurrence in 2003. The viruses pose a threat of emergence of a global pandemic influenza through point mutation or reassortment leading ...
