Does H. pylori have paracellular activity?
I found no evidence for paracellular movement.

Some notes of mine


  
  Mucinase $\to$ lophotrichous flagella $\to$ Transcellular (actin fibrils, tails) movement
  ICF Vacuolating cytotoxin (VacA) $\to$ altered T-cell function $\to$
  damages epithelial cells, disrupts tight junctions and causes
  apoptosis. 
  


I think the latter point makes transcellular momevment possible.
I see no way how paracellular movement would be possible.
