doi: 10.3390/pharmaceutics17121557

Figure Lengend Snippet: Phylogenetic tree based on the DNA gyrase B ( gyrB ) gene sequences showing the relationship between isolate M2 and reference strains of Lactiplantibacillus plantarum . The tree was constructed using the Neighbor-Joining method with 1000 bootstrap replicates in MEGA X. Enterococcus faecalis JCM 5803 and Escherichia coli E1542 were used as outgroups.

Figure Lengend Snippet: Survival curves of Tenebrio molitor larvae challenged with enteropathogenic bacteria. ( A ) Survival curves of larvae infected with Escherichia coli 042. Groups include PBS control, M2 alone, infection alone ( E. coli 042), prophylactic treatment (M2 administered 2 h before infection), and post-infection treatment (M2 administered 2 h after infection). ( B ) Survival curves of larvae infected with Salmonella enterica ATCC 13076. Groups include PBS control, M2 alone, infection alone ( S. enterica ), prophylactic treatment, and post-infection treatment. Survival was monitored daily for 10 days.
