Although mutations conferring drug resistance were present in all lineages, the proportion of resistant and susceptible isolates varied between lineages.
We demonstrated that with a seed mixture, in most cases the higher the rate of larval movement, the higher the proportion of resistant insects in the population in an area, regardless of the type of resistance tested.
Though associated with high level resistance, its detection at onset could imply a smaller proportion of resistant bacteria.
For enterobacters, the proportion of resistant isolates rose from 1990 to 1996, but the number of laboratories reporting resistance was relatively constant from 1992 to 1997.
However, resistance in retail beef was fairly low; therefore the proportion of resistant E. coli from retail beef was only 48%.
The resistance percentage for each genotype was an estimate of the proportion of resistant plants within the population.
Instead of wiping out bacteria randomly, the way regular soap or alcohol-based products do, triclosan may inhibit the growth of bacteria in a way that leaves a larger proportion of resistant bacteria behind, according to lab studies at Tufts and Colorado State Universities, among others.
Tamiflu-resistant strains of H1N1pdm09 have been identified in Europe but only on an ad hoc basis, said Hurt. "However, the trend observed in Australia of a greater proportion of resistant cases being detected in untreated community patients is also being observed both in the USA and Europe," he said.
In the two homogeneous mixtures that differed by the proportion of resistant plants, disease reduction was similar.
Field-observable and micromorphological properties, degree of weathering, and proportion of resistant minerals are also useful as criteria for paleosol orders.
In homogeneous mixtures, a high proportion of resistant plants was associated with high canopy density, which led to a microclimate favorable to disease development.
