Relative to OP50 feeding, colonization with B. longum resulted in the suppression of forkhead box protein O (daf-16), LC3, GABARAP and GATE-16 family (lgg-1), and beclin homolog 1 (bec-1), leading to the attenuation of autophagy in C. elegans in response to Salmonella infection. The gene discussed is MAP1LC3A; the disease is Salmonella Infections.
