Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

G. G. Jackson The pathogenesis of bacterial infection defines the dynamics at an interface of ecologic association of bacteria and host. First, it occurs at the portal of initial contact with a per missive target cell. The infected cell provides either a passive or a specific receptor for the bacterium or its products, to gether with ligands and an environment of helper and inhibiting factors. The result is bacterial replication to produce an im balance of a potentially commensal relation which, under other defined conditions, would be optimal for the survival of both the host and bacterial cells. Virulence and pathogenesis are both absolute and relative terms. They must be interpreted strictly according to the circumstances of site-specific inter actions of bacterial and host cells, membrane composition, structure, characteristics, and environmental substances. The bacteria themselves may have, acquire, or switch on or off under certain conditions, the products or properties that produce cellular damage that we recognize as virulence. Another result of bacterial infection may be to stimulate a normal host cell function to perform at a pathophysiologic level, causing illness that we recognize as virulence. A third marker of virulence may be the ability to invade a cell or tissue barrier and produce a pathologic effect at a site that is remote from the portal of commensal association or pathologic entry."
