Sentence examples for viruses within the same from inspiring English sources

Because viruses can compensate for the deleterious mutations by exchanging the superior protein products between viruses within the same host, the viruses in the highly coinfected setting were under weaker stabilizing selection than those evolving under low coinfection that were unable to compensate.

It has been observed frequently that individuals recovered from influenza virus infection are protected against subsequent infection by antigenic drift variant viruses within the same subtype [10], [11], [12] and to a lesser extent from infection by a different subtype due to heterosubtypic immunity [13].

In fact, the simultaneous occurrence of GI and GII viruses within the same outbreak was observed.

Moreover, sIgA is known to induce cross-protection against variant viruses within the same subtype and also increase the protection during epidemics of heterologous viruses (6, 13– 13).

Since the probes were designed against conserved sequences, the ViroChip could be used to identify novel viruses within the same family as a known, sequenced virus.

The presence of multiple viral variants can produce HIV-1 recombinant strains that contain sequences either from different genetic subtypes (intersubtype recombination) or different viruses within the same subtype (intrasubtype recombination).

The NA stalk region varies considerably among different viruses, even within the same subtypes.

In some instances, mixed populations of viruses exist within the same animal.

H5N1 viruses have continued to mutate in avian populations, and in clinical trials of an unadjuvanted H5 vaccine, serological cross-reactivity to variant H5 viruses even within the same clade was only 20%30%% [ 4], although use of an adjuvant may improve this.

In general, PRRSV strains are grouped into European (type 1) and North American (type 2) genotypes [ 11- 13], but high levels of genetic variability still exist among viruses, even within the same genotype [ 10, 14, 15], which results in suboptimal cross-protection between different PRRSV strains and becomes a significant impediment to the development of effective vaccines.

The high prevalence of HIV in Malawi, combined with the severe implications of co-infections with hepatitis viruses, necessitate clarification of the levels of multiple hepatitis virus infections within the same population.
