Being acid-labile, HRVs do not colonise the gut, and are most commonly transmitted by the respiratory-salivary route, both by person-to-person contact and airborne transmission.
It is possible that looking at a wider geographical scale in the Atlantic herring could reveal a geographical basis for the lineages that we found, or reveal additional lineages that did not colonise the Baltic Sea.
The second colonization of Africa by Asian ancestors resulted in Hallelesis and Bicyclus on continental Africa, the descendants of which did not colonise other regions but rather diversified only in continental Africa.
It didn't colonise the charts in the way garage did, or travel the globe as widely as would dubstep, its successor.
It's in Melbourne, which is a place he never visited and Europeans didn't colonise until 40 years after Cook died.
The strain with site 3-mutant urease did not colonise mice (data not shown) and was not studied further, whereas each of the other three mutant strains colonised mice as efficiently as the wild-type in short-term (<3 months) infections.
Although the bacterium persists in the murine intestinal mucosa for few weeks [ 28], it does not efficiently colonise the murine gut.
Alternatively there may be issues in sampling as H. pylori does not uniformly colonise the stomach lining causing varying population densities.
But, says Salzburger, "Cichlids have colonised all the lakes - remote lakes, satellite lakes, crater lakes - and they must have got there somehow". So if hybridisation does not drive a new radiation, then recolonisation from refugia could, but over a much longer time course - millennia as opposed to decades.
Begun in 1973 and completed three years later, it seems in retrospect to have been the real turning point in Davies's development; the orchestral works that followed, including the subsequent symphonies, did not so much colonise new musical territory as rework and redefine existing principles.
