A previous study assessing the impact of tetracycline and doxycycline exposure on stool bacteria showed no increase in pathogen quantities, to include Klebsiella, Enterobacter, Pseudomonas, Proteus, Serratia, or E. coli[ 23].
While the search for food often establishes the contact between host and pathogen, food quantity and quality may play a role later in the infection process.
In response to a pathogen, large quantities of proinflammatory cytokines are released in an unregulated immune cascade that can cause multiple organ failure [ 23, 24].
Production of the pathogen in adequate quantities must be possible either in vivo (insects) or in vitro (artificial medium).
There is no doubt that the host inflammatory reaction is driven by pathogen-derived signals [21], [22], and that the intensity of the inflammatory response depends on the quantity of pathogen (i.e., Mtb load).
The quantity of pathogen influxes from tributaries of lakes and reservoirs during the rainy season is of particular importance in determining pathogen transport and distribution (Brookes et al. [2004]).
The functions used to generate a probability of disease given a quantity of pathogen ingested (dose response) were derived from dosing trials where healthy volunteers were given known quantities of pathogens.
However, when they considered quantity of pathogen on a continuous scale, 3 organisms (rotavirus, astrovirus, and Shigella spp).
What is more, CDA-AMB-NP treatment also significantly reduced the quantity of pathogens in various organs of the infected mice.
For example, a study of Buttermilk Bay has shown that groundwater is capable of transporting a large quantity of pathogens from surface to sub-surface water either by direct discharge or by discharge to rivers flowing into the bay (Moog [1987]; Weiskel et al. [1996]).
These approaches can be used with both non-culturable pathogens and when sample quantity is limiting.
