Sentence examples for more efficient virus from inspiring English sources

This finding is consistent with results from studies during the 2003 outbreak that suggested high virus titers are associated with more severe illness and more efficient virus transmission (19, 20 ).

Specifically, CA04-infected macaques exhibited higher body temperatures, more efficient virus replication in both the upper respiratory tract and lungs, increased production of pro-inflammatory cytokines (e.g., CCL2 and IL6), and more severe lung lesions at both early (3 days) and late (7 days) times post-infection.

Possible explanations for timing of the epidemic could be increased mobility after fledging and, therefore, increased contact rate; access to water, facilitating more efficient virus transmission; and increased susceptibility of fledglings as a result of immature body condition and loss of maternal antibodies.

Recent tools in our arsenal include the increasing availability of genomic microarrays [ 4], siRNA-mediated gene knockdown [ 5], more efficient virus-based gene delivery systems [ 6, 7], and high-throughput sequencing [ 8].

It is possible that increased levels of influenza virus production by spherical strains will results in more efficient influenza virus transmission.

Macrophages, the natural host cell of PRRSV, are more efficient for virus isolation [ 47].

Hypothetically, shedding in saliva might be more efficient for virus transmission in male bank voles living in a high-density area during mating season, when many fights occur.

We have previously found that de novo infection of naïve cells by KSHV is more efficient when the virus is cell-associated rather than cell-free and, thus, a more sensitive means of detecting low levels of infectious virion production in the laboratory setting [24].

Hence, it will be interesting to determine the mechanism(s) that mediate what appears to be more efficient de novo virus production in the Huh7-2, -3 and -9 cells (e.g. packaging, maturation and/or secretion) as such studies may identify critical cellular factors involved in these processes.

Furthermore, the higher serum levels of IgG2a, which is regulated by Th1-associated cytokines[37], in sHA.GCN4pII vaccinated mice might suggest that the finding of more efficient clearance of virus could be related to the effector functions of IgG2a such as complement activation and Fc receptor binding[23], [38], [39].

We hypothesized that these genes may be responsible for the more efficient control of virus replication in C57BL/6J mice.
