Bee trials:

Treatment Before After
None Somewhat lethargic. Drank when prompted. Appeared tired, but otherwise unaffected.
0.00% Most lethargic, did not eat when offered Wet and slow moving.
0.05% Very vigorous; ran around inside the tube. Fed. Very energetic. Unaffected by treatment.
0.2% Very vigorous; ran around inside the tube. Fed. Slightly less energetic than the 0.05% bee.

The bees will be able to survive all of the oxalic acid that the E.coli can produce.

Mite trials:

Control Oxalic Acid RFP
Parafilm Pouch Mites dead Mites dead Mites dead
Larvae 1 Mites dead Mites dead Mites dead
Larvae 2 Mites dead Mites dead Mites dead

The mites did not survive any of the trials.

Antibiotics testing:

Test (Antibiotics) Result After
AMP 1 Positive
AMP 2 Positive Wet and slow moving.
CAM 1 Positive
CAM 2 Positive
TET 1 Positive
TET 2 Positive
Control (water) Positive

The results we got for antibiotics testing show that biofilms can still be recultured even after being treated with antibiotics.
