2.   Once sprayed with the mix, the chicks ingest the bacteria while preening themselves.

4.   The researchers suggest that the ability to ingest bacteria may be a strategy by which plankton adapt to grow in iron-poor seas.

5.   They give blood, take experimental vaccines and ingest suspect bacteria, and when they become sick they are treated on the spot.

6.   Those cells could not ingest Pseudomonas bacteria, the team reported.

7.   But it says the nature of his symptoms suggests he was exposed through his skin rather than by ingesting bacteria.

9.   Symptoms of shigella infection typically appear one to three days after ingesting the bacteria.
