may allow them to reach the lower airways, suggest the authors. Unlike pollens, moulds are also present through the year with increase in the spore counts during the autumn months. Furthermore, the level of mould exposure is probably greater because ...
Molecular mechanism underlaying anthrax infection described by UCSD School Of Medicine researchers
... When the bacterium (b. anthracis) is inhaled, its spores
are surrounded by alveolar macrophages in the lung, the beginning stage of normal immune response. But instead of succumbing to the defensive assault, they survive and germinate within the cells, traveling with the macrophages in their normal sentine...
