The leading variety in New York, MacDonald, is a vigorous, productive strain with large stalks that vary greatly in color, but are typically reddish or speckled pink at the bottom and green at the top.
And Jackson, who replaced addiction with some vigorous strain of workaholism, has stayed busy for the entire two decades since.
This vigorous strain ("pig") does mate, albeit lethally, and perhaps more significantly, its macronucleus contains DNA sequences that are normally micronucleus limited [ 44], i.e., excised during macronuclear development.
Or, less vigorous strains might have been less debilitating to their hosts during their migrations or residence in harsh (e.g. Arctic) environments; those that least impaired human survival would have enjoyed the best chances of transmission from adults to their infants, and thus persistence in these small human populations.
- In the already-cited study by Belshe et al., intradermal vaccination with 6 μg HA per strain elicited a vigorous immune response in subjects >60 y, comparable to that provided by the conventional 15 μg intramuscular vaccine, with the only exception for H3N2 antigen, for which a significantly higher response was observed in the intramuscular group.
Also, the presence of multiple-copy protein families for central carbon metabolism secures a vigorous and regulable primary metabolism in strain 5008, which probably provides various precursors for secondary metabolism in different niches.
As Faust, the tenor Paul Groves had moments of worrisome strain in his upper range but over all gave a vigorous and ardent performance.
E. coli K-12 MG1655 strain growing on LB-glucose harnessed with 0.5% Difco agar exhibits a vigorous flagella-driven swarming migration, developing a robust colonial pattern associated to this type of motile collective behavior [ 7].
These mice are known to be more prone to a vigorous Th1 response and are relatively resistant to infection with B.anthracis compared to other strains including C3H [34], [34].
