Perhaps you should try some spelling variations:
bacterial effector » bacterial vector (Expand search), bacteria effect (Expand search), bacterial infection (Expand search)
decrease bacterial » increase bacterial (Expand search), decrease arterial (Expand search), increased bacterial (Expand search)
decrease rate » decreased rate (Expand search), decreases rate (Expand search), decrease at (Expand search)
rate decrease » rats decreases (Expand search), rate increase (Expand search), to decrease (Expand search)
decrease will » decrease with (Expand search), decrease cell (Expand search), decrease il (Expand search)
decrease the » decreases the (Expand search), decrease in (Expand search), decrease of (Expand search)
the decrease » to decrease (Expand search), and decrease (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease the decrease rate decrease ) OR ( decrease will decrease bacterial effector ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease the decrease rate decrease ) OR ( decrease will decrease bacterial effector ))*.
