They calculated that these changes represent 'a loss of 148 CD4 [cells/mm.sup.3] and an increase of 0.39 log10 copies/ml RNA over a 30 year period (from the first CDC report of the epidemic in 1981).' Even larger changes were observed in patients with a known date of infection with HIV.
The means and standard deviations obtained in the tests and the results of the statistical analysis of the CFU/mL (Log10) for biofilms isolated from the control, AS I and AS II groups are shown in Figure 1.
The average D-10 value, the radiation dose needed to inactivate 1 log10 of pathogen on the three products, was 0.61, 0.54, 0.47, 0.36 and 0.15 kGy for Salmonella spp., S.
All indicator strains were incubated in Luria-Bertani (LB) broth overnight and then diluted to 7 log10 CFU/mL with LB broth.

In Phase 1b clinical studies, HCV-infected patients receiving doses ranging from 200 to 600 mg twice daily, and 400 to 600 mg once daily, showed mean maximal reductions in viral load ranging from of 3.63 log10 to 4.25 log10.
But when the almonds were directly suspended in water and then pressurized, the researchers achieved a log10 reduction of approximately 3.37.
Median reduction in HCV RNA concentrations among the treatment-naive patients was 5.1 log10 IU/mL, and among the previous null responders it was 4.9 log10 IU/mL.
