On the other hand, decrease rate of the current density on the amorphous specimen was smaller than that on the crystalline specimen, indicating the regeneration of passive film on the amorphous specimen was delayed probably because the amount of metal ions dissolved at the initial stage, i.e. the source of re-passive film, was smaller on the amorphous specimen.
That's what we get from this powerful source of re-creation right next to us, the visceral evidence that we can feel better, that things change, and that we are not alone.
Leptospires cause chronic infection in domestic and wild mammalian species that harbor the bacteria in their renal tubules, shedding them through the urine into the environment, thus constituting a source of re-infection in other animals.
If the virus was circulating for up to a year before detection, then it seems difficult to assign the geographic source of re-introduction (i.e., China or Russia) based solely on surveillance in 1977.
Direct comparisons with other studies are less straightforward, either because efficacy was monitored over a shorter period of time [22], [26], [33] or because untreated cohorts provided a potential source of re-infestation, that may have extended the time taken to reach maximum efficacy or reduced the duration of efficacy [21], [34].
Eggs that fall off the host can be a source of re-infestation.
Contaminated hands can also be the source of re-contaminating the surface, as shown with HAV [ 55, 58].
Kissing contacts have previously been suggested as a risk factor for carriage of F. necrophorum [ 20] and a partner could thus be an important source of re-colonisation.
A planned one-off moratorium of 3 weeks at the hottest month of the year should decrease the environmental burden as a source of re-infection.
Insufficient cleaning of the environment and in-contact dogs and cats not treated against Cheyletiella may be a source of re-infestation.
