Sentence examples for virus variability from inspiring English sources

Virus variability was established by comparing a portion of 914 bp of the highly variable ANDV medium RNA segment.

In some cases involving high virus variability, the cross-reactivity of CD8 responses may be beneficial for recall responses [7], [9].

Efforts aimed at developing an anti-HCV vaccine have been hampered by the high virus variability, the substantial lack of readily available animal models, and the absence of clearly established in vitro correlates of protective immunity.

Another more dangerous and less predictable phenomenon responsible for the virus variability is called "antigenic shift".

More information of virus variability of all the ANDV lineages will also help differentiate an instance of common rodent exposure from a new event of person-to-person transmission, especially in patients with a travel history.

A critical and contentious issue in HIV-1 vaccinology is how the vaccine-induced T cell responses will cope with both the intra- and inter-clade virus variabilities.

Previous studies have linked RNA virus genetic variability to changes in viral pathogenesis, the ability to adapt to a host during infection, and to the acquisition of mechanisms required to switch hosts entirely.

We investigated the dynamics of porcine reproductive and respiratory syndrome virus (PRRSV) variability in a range of swine PRRS-positive farms located in Northern Italy, to provide insights into the epidemiology and diffusion of the virus, particularly throughout the entire swine production chain.

Although no virulence differences between a and b subtypes have been found [ 30], subtype identification is relevant to understand virus genetic variability and contribute to molecular epidemiology studies.

For the same reason we also decided to apply conventional probes for the detection of pandemic A(H1N1) viruses, because in April 2009 the assay designs had to be based on single sequences without any knowledge concerning the viruses sequence variability.

This means that some of their findings, including the suggestion that past flu jabs may provide some protection against current strains (which is intriguing, because of the virus's annual variability) cannot be stated with much confidence.
