The detection limit for WNV by both methods is as low as 0.08 PFU (1.9 log10 PFU/mL), which indicates that RT-PCR is more sensitive than cell culture and more accurately indicates infection, since RNA is more stable than infectious virus in tissues (3 ).
Therefore, despite the acceptance of Vero cells for many candidate DEN vaccine productions, the current findings indicate that MRC-5 cells grown on microcarriers may offer a more stable system for DEN virus production.
These environmental conditions were reported to be favourable for virus survival as the A/H5N1 viruses are more stable in wet and fresh feces of infected animals [ 15, 16].
Part of the explanation has to do with the obvious seasonal differences: In 2007, researchers reported that the flu virus is more stable and stays in the air longer when air is cold and dry.
The findings need to be confirmed in people, he says, but a possible reason for the increased transmission is that the flu virus is more stable at colder temperatures and lower humidity.
He claimed that the dry virus was more stable and more easily standardized.
In contrast, shedding in feces, which may provide the virus with a more stable environment, may play a more dominant role in transmission in a low-density area during fall or winter.
ABSTRACT: In this research we hypothesize that a direct link is established between lattice walks and the RNA sequence of a short domain of the 3′-UTR of a selected strain of the YF virus and a more stable strain is predicted.
Consistent with early experiments on virus aerosol stability[13], [14], in the absence of UVC, vaccinia virus appeared to be more stable and higher aerosol concentrations were achieved with low RH (winter conditions) than with high RH (summer conditions).
The new vaccine contains a synthetic viral protein, which prompts the immune system to better recognise the Ebola virus, and is much more stable when stored long-term.
