However, because measurement of colony counts is not standardized, no other source was initially evident, and because there is no known safe level of Legionella, we applied the precautionary principle and recommended that all positive towers be remediated regardless of their colony count.
Because of the colony's slum-like spirit, DDA officials and others behind the conversion justify the imminent bulldozing as a lifestyle improvement.
Our model does not consider the impact of brood diseases on colony failure, however we believe our approach is still useful because many cases of colony failure and CCD are not caused by brood diseases [21], [22], [23].
Currently, honey bees (Apis mellifera) draw a lot of public and scientific attention because of increased colony losses [ 1, 2], which are partly caused by infection with Varroa mites [ 3].
Because a colony of weak discriminators is more effective than an individual with even maximal recognition ability (given physiological constraints), there may be less selective pressure at the individual level for increased recognition ability than previously thought.
This assay is a sensitive parameter of toxicity because the number of colonies formed is assessed when the cells are in a state of proliferation.
One sample was excluded from analysis because the number of colonies on the culture plate was too high for accurate determination of CFUs/mL.
Because of concern that colony forming assays might not accurately reflect cytotoxicity, we also examined flavopiridol-treated cells by trypan blue staining and flow cytometry.
Until the end of the 170s the impoverishment of humble citizens had been counterbalanced to some extent by the founding of colonies, because dispossessed peasants were given new lands in outlying regions.
Only three temperature treatments were performed because an insufficient number of colonies was available for four treatments.
Fernández-Marín et al. [25] further substantiated Eidmann's hypothesis, suggesting that M. smithii colonies might be secondarily polygynous, because pleometrosis, the foundation of colonies by multiple queens, does occur in some colonies.
