Sentence examples for a decrease in virulence from inspiring English sources

Intriguingly, the pqsH mutant did not result in a decrease in virulence in burn-wound mouse model (Xiao et al., 2006b), but displayed a reduced killing on nematodes (Gallagher et al., 2002), hence the importance of PQS in regulation of virulence remains debatable.

Moreover, replacement of the PB2 or PB1 proteins led to decreased replication in tissues and, consequently, a decrease in virulence [48].

Even more intriguing, the introduction of a functional yadA gene in Y. pestis EV76 was shown to correlate with a decrease in virulence in a mouse model.

Moreover, it is important to notice that AH-3 ΔwaaL [23] mutant showed a decrease in virulence but not to the same extent as that of the AH-3 ΔwaaE mutant.

This study is the first to show a decrease in virulence of genetic variants of the same strain sequentially isolated from a human patient, suggesting that C. albicans is able to adjust to the host, favoring commensalism rather than increase of virulence.

The virulence was assayed for these 6 new mutants and it was shown again that the deletion of xyn11A resulted in a decrease in virulence.

SpeB is formed by most GAS strains, and, therefore, any decrease in virulence may also be affected by an inhibition of speB gene expression or by the chemical inactivation of the protein itself.

Alternatively, protozoan predation could also lead to a decrease in bacterial virulence if increased allocation to anti-predatory traits is traded off with virulence factors of the pathogen.

These genes were selected because the encoded proteins had known functions in innate immunity and the deletion of each gene individually had caused a decrease in virus virulence in the murine intranasal and intradermal models of infection and an increase in immunogenicity.

As such, the decrease in expression of this regulator under NaCl- and KCl-induced stress may be associated with a decrease in the virulence of the pathogen.

Analysis of the timing and mortality patterns of the disease reveals a striking pattern of speed deceleration, reduction in peak-week mortality, a prolonging of the epidemic wave, and a decrease in overall virulence of the pandemic over time.
