Hace 5 días · To understand how plant viruses evolve HT and/or VT, it is first necessary to summarize how they are transmitted. Horizontal transmission by arthropods, particularly aphids, is the most frequent ...
Hace 3 días · 22 May 2024 Health. A comprehensive review by the UN health agency has revealed critical gaps in understanding the full impact of climate change on malaria, dengue, trachoma and other tropical diseases. The World Health Organization ( WHO) study, conducted in partnership with Reaching the Last Mile (RLM), a global health initiative to eliminate ...
Hace 3 días · For the efficient vector, Rh. padi, we show that virus transmission efficiency is influenced by genetic variation, and we identify 542 SNPs that potentially influence virus transmission. Broadly, our findings help disentangle the relationship between vector diversity and the transmission efficiency of important plant viruses and ...
Hace 3 días · Abstract. The transmission efficiency of aphid-vectored plant viruses can differ between aphid populations. Intra-species diversity (genetic variation, endosymbionts) is a key determinant of aphid phenotype; however, the extent to which intra-species diversity contributes towards variation in virus transmission efficiency is unclear.
Hace 3 días · A post on X has claimed that an Ebola-like virus is “sweeping through Spain”. The same claim has also been shared on Facebook.. The post provides a link to an article in The Daily Express US which describes a deadly virus ‘surging’ through Europe in its headline.. Both of these statements are misleading. As the Express article goes on to say, there has been one new confirmed case of ...
Hace 2 días · Polio is most infectious between 7 and 10 days before and after the appearance of symptoms, but transmission is possible as long as the virus remains in the saliva or feces. Virus particles can be excreted in the feces for up to six weeks.
Hace 5 días · Ebola, contagious disease caused by a virus of the family Filoviridae that is responsible for a severe and often fatal viral hemorrhagic fever. Outbreaks in primates—including gorillas, chimpanzees, and humans—and domestic pigs have been recorded. The disease is characterized by extreme fever, rash, and profuse hemorrhaging.
