The increase in the expression of the Esx genes (Table S2A) either results from the damage to the Mtb cell-envelope by THZ or may reflect increased secretion of virulence related substrates by the pathogen.
Variations in these ratios may reflect variation in strain virulence, the influence of initial viral load, or host factors such as susceptibility.
Analysis of the whole genome of HPAI A(H5N1) virus provides valuable insight into the presence of mutations that may reflect adaptive changes, altered virulence, and/or transmission phenotype.
No changes were detected in the counts of lactobacilli when baseline values were compared with the values obtained after the test period.> The polysaccharide content of plaque may reflect plaque adhesion and virulence.
Lack of signs of hepatitis in sick dolphins may reflect restricted tissue tropism or virulence of this adenovirus compared to those of the adenovirus identified in sea lions.
Loss of virulence factors may reflect that these organisms generally have adapted to a broader ecological niche, which is supported by the high genetic diversity demonstrated by AFLP.
The presence in a population of multiple host resistance alleles confronting multiple parasite virulence alleles may reflect a dynamic equilibrium permissive for the persistence of both parties.
These differences may reflect strain-specific fine-tuning of virulence circuits.
Because B. mallei also has a type VI secretion system (T6SS) essential for virulence [27], the data may reflect partial attenuation.
Since the beginning of the 2009 pandemic, some mutations have occurred in functional viral genes, which may reflect adaptation to humans and/or changes in virulence, but there is no evidence of antigenic change [17].
