Sentences with phrase «other flaviviruses»

In general, examining the potential effects of other flaviviruses on pregnant women and their developing fetuses is difficult, because outbreaks have been sporadic and less widespread than with Zika.

Scientists are most curious about what makes Zika virus different from other flaviviruses.
The new 3 - D structure, which was obtained using X-ray crystallography and electron microscopy, revealed that the outer surface of the Zika NS1 protein has substantially different electrical - charge properties than those of other flaviviruses — indicating it may interact differently with the members of an infected person's immune system.
This region varies not only among Zika virus strains but also in other flaviviruses, which suggests that differences in this region may influence virus transmission and disease.
Studies suggest that Zika - induced antibody responses may also cross-react with other flaviviruses, particularly dengue virus.
The high - resolution structure of the Zika virus showed that the overall virus architecture is similar to other flaviviruses such as the West Nile and dengue viruses.
Other flaviviruses, such as West Nile virus, are rapidly spreading around the globe.
The structure of mature Zika virus is similar to other flaviviruses, except in the region of a potential cell attachment site.
The structure reveals key interactions that probably contribute to the high catalytic efficiency of this enzyme relative to other flaviviruses, indicating promising starting points for drug design.
Assays already exist to detect Zika virus infection, but they either work only shortly after infection or are poor at differentiating Zika from other flaviviruses.
The assay was implemented in five countries and tested using a large number of clinical samples from travelers and patients living in areas with a high level of exposure to Zika virus and other flaviviruses.

The catch is that, although the antigens bind with the antibodies according to the lock and key principle, they almost always do so at the same site as all other flaviviruses.
A near - atomic level map of Zika virus shows its structure to be largely similar to that of dengue virus and other flaviviruses, but with a notable difference in one key surface protein, report scientists funded by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health.
Given the concerns for immune enhancement with other similar flaviviruses, like yellow fever and Japanese encephalitis, ZPIV will be tested in some volunteers who will first be vaccinated against one of these other flaviviruses.
ZIKV infection diagnosis relies on serology — which is challenging due to cross-reactions with other flaviviruses and / or absence or low titer of IgM and IgG antibodies at early phase of infection - virus isolation, which is labor intensive, time consuming and requires appropriate containment.
The current test suffers from cross-reactivity and a lack of precision in areas where DENV or other flaviviruses may coexist.
