Virulence in a sentence

Virulence Virulence (the tendency of a pathogen to cause damage to a host's fitness ) evolves when that pathogen can spread from a diseased host, despite that host being very debilitated.

However, he didn’t anticipate the virulence of the backlash, with critics accusing the house of glamorizing trophy hunting.

Obtaining a complete evolutionary history of this strain will now allow researchers to understand how bacteria obtain the genetic material responsible for severe virulence in the first place, and analyze ways to combat them.

And the pathogen has had high virulence based on historical cases.

Assuming the contagiousness and virulence of Neolithic diseases increased through time, dense settlements such as Çatalhöyük may have reached a where the effects of disease outweighed the benefits of living closely together.

Studying revived viruses can help us understand their evolution, transmission, and virulence, potentially leading to better vaccines, diagnostics and treatments for existing or similar viruses.

As it replicates it produces multiple mutations, although none has been found to change its virulence.

He did not challenge the disease’s virulence but suggested it might compress the annual flu death rate into a few weeks – putting intense pressure on hospitals – with the only “extras” coming from non-vulnerable groups.

In September 1668, Samuel Megapolensis, the pastor of the Dutch church in the newly created city of New York, wrote to a friend about how the Lord had “visited us with dysentery, which is even now increasing in virulence.

You could ask little more of Wood, who has perfected the art of icy virulence forged from the ash of vulnerability.

A phase 1 clinical trial of vaccines made from these viruses showed that they were well tolerated, produced an immune response and had reduced (but not zero) reversion to virulence compared to the original oral vaccine for PV2.

After studying 1000 different SNPs, they found a single nucleotide difference that is unique to the African ST313 strain and causes high expression of a virulence factor called PgtE that prevents Salmonella being killed in the bloodstream.

Everyone knows that the anonymity of the internet racist provides people the opportunity to spew their virulence unchecked.

As such, the ability to form biofilms alone may be linked to the increased virulence in some of the strains.

Bell, Folio ed. p.10 Contemporary accounts suggest cases of plague occurred through the winter of 1664/5, some of which were fatal but a number of which did not display the virulence of the later epidemic.

In the light of the virulence of the plague that had subsided only seven years previously, Wycliffe's studies led him to the opinion that the close of the 14th century would mark the end of the world.

It not only induces biofilm formation, but also increases virulence in pneumonia and meningitis.

MetaPathogen.com. The relationship between virulence versus transmissibility is complex; if a disease is rapidly fatal, the host may die before the microbe can be passed along to another host.

Other reports have shown that the biofilm-associated protein (BAP) in A. baumannii, involved in biofilm formation, is capable of stimulating humoral response in mice, which suggests that it may have a role in virulence.

Pathogenesis V. cholerae pathogenicity genes code for proteins directly or indirectly involved in the virulence of the bacteria.
