I came across these lines from this paper:
Pathogenic microbes exert a broader sphere of influence by releasing a bolus of toxin that can act upon many cells within a given tissue and/or diffuse away to modulate one or more types of cells at multiple locations within the host.
What does this line mean? Does it mean that the pathogen releases multiple types of toxins or does it mean that the pathogen releases just one type of toxin in a large quantity?
