In contrast, only a minority of children from 'developed' countries becomes infected, and infection frequency increases proportionally with age (Pounder and Ng 1995; Kusters et al. 2006).
Infection frequencies suggest that ∼1/3 of SUP05 bacteria is viral-infected, with higher infection frequency where oxygen-deficiency was most severe.
In contrast, infected females' eggs are "immune" to this lethal effect and develop normally into infected adults, so that the infection frequency tends to increase.
Accordingly, migration out of infected demes will drive up infection frequency in adjacent demes very effectively and is more likely to bring infection frequency in the range of positive selection for infection.
Frequency of lipodystrophy according to duration of HIV infection; Frequency of lipodystrophy according to ART regimen; Frequency of lipodystrophy according to duration of ART; Frequency of lipodystrophy according to risk factors.
For other respiratory viruses (excluding AdV), a 3.5-fold reduction in their infection frequency was observed in HRV-C co-infected subjects (12.9% to 3.7%; p<0.001).
Other than for D. simulans and D. melanogaster, in which the infection frequency was under 1%, both sexes of infected species were found to be Spiroplasma-positive, indicating the absence of a strong male-killing phenotypes.
Females' offspring infected by a compatible Wolbachia are immune to this effect so that the infection frequency tends to increase [2].
For infection frequency, we first confirmed that there was no difference between the two infected lines, using a paired t-test (t = 1.51, d.f. = 8, P > 0.05).
Nosocomial infection frequency in adequate and insufficient caloric intake groups were similar, respectively.
Two patients had documented infection (infection/colonisation index, 3.6%; overall VRE infection frequency, 0.4%), but both recovered and were discharged.
