sentences:  They observed "S. citri" in the gut as well as the salivary glands of the insects which further proves that the pathogen may be transmitted by the mechanisms described in the studies above.In particular, researchers observed that "S. citri" were often found within gut epithelial and salivary gland cells on infected hosts within small membrane bound vesicles.This led them to believe that the "S. citri" pathogen may be using cell mediated endocytosis as a predominant way to enter gut and salivary cells and may be travelling directly though the cells rather than travelling in the spaces between cell membranes of individual cells through a process called diacytosis.
