Sentence examples for amount of virulence from inspiring English sources

A recent example demonstrates the value of just the right amount of virulence.

The MRCA for putative pathogens showed a probability distribution for genes presence that resembled the Campylobacter MRCA (fig. 2 B), indicating that the reduced amount of virulence genes present in putative pathogens were present in the ancestor or have been probably acquired through recent horizontal gene transfer events.

Thus, in our case, the important cytotoxic effect of S. aureus BCSs compared to that of PCSs could be related to the presence of higher amounts of virulence factors including exoenzymes such as DNase, which may disturb the biological activity of human cells (Modun and Williams 1999; Pancholi and Chhatwal 2003; Jarosław et al. 2005; Secor et al. 2011).

In addition, our results showed that sessile cells produce higher amounts of different virulence factors which represent a serious threat in case of human infection by S. aureus.

This may have facilitated the evolution of antigenically divergent strains and, more recently, the emergence of a lineage (designated the P3 lineage) that produces higher amounts of several virulence factors, including pertussis toxin (Ptx).

Both the amount and virulence of the microorganisms and the resistance factors of the host (risk factors and immune status) are crucial for the initiation and progression of the periodontal destruction [ 3].

Both the amount and virulence of the microorganisms and the resistance factors of the host (risk factors and immune status) are crucial for the progression of the periodontal destruction.

Research has shown that, apart from those derived from social pressures and obstetricians' influences, spontaneous maternal requests for caesarean delivery are probably for the time being a more limited phenomenon than suggested by the amount and virulence of the debate raised around it [ 58].

In F. verticillioides, reduced fumonisins biosynthesis in an FvVE1 mutant goes along with reduced pathogenicity on maize seedlings (Myung et al. 2009), and in F. fujikuroi, single deletions of Ffvel1, Ffvel2, and Fflae1 decrease the amount of gibberellic acid and virulence in rice (Wiemann et al. 2010).

This observation could explain the large amount of sRNAs frequently found near virulence genes, which are acquired by horizontal transfer during exposure to high selection pressure occurring, for example, in host infection.

However, the vaccine effectiveness drops to zero with an increased amount of contamination with a middle virulence MDV strain.
