^an = 3 petri dishes.

^bValues in the same row differed significantly at a P value of <0.05 as indicated by different letters.

^cLethal treatments were the following: galactosamine (1 mg/slug) alone, M. osloensis LPS (0.03 mg/slug) alone, 1 mg of galactosamine plus 0.03 mg of LPS per slug, and 1 mg of galactosamine plus 0.03 mg of LPS plus 3 mg of uridine per slug.

^dSublethal treatments were the following: galactosamine (0.3 mg/slug) alone, M. osloensis LPS (0.01 mg/slug) alone, 0.3 mg of galactosamine plus 0.01 mg of LPS per slug, and 0.3 mg of galactosamine plus 0.01 mg of LPS plus 1 mg of uridine per slug.
