The aim of the present study was to investigate the microbiota of processed ready-to-eat (fried or boiled) edible insects sold by street vendors at local green markets in Thailand (Bangkok and Koh Samui). To this end, samples of 4 insect species (rhino beetle adults, silkworm pupae, giant waterbugs adults, and black scorpions) were collected and analyzed through viable counting and metataxonomic analysis. Enterobacteriaceae showed counts below 1 log cfu g in all samples, except for black scorpions, which showed elevated counts reaching up to 4 log cfu g. Total mesophilic aerobes counts were up to 8 log cfu g in all the analyzed samples. Counts below 1 log cfu g were observed for , , sulfite-reducing clostridia viable cells and spores, and . All the samples showed the absence of and spp. According to metataxonomic analysis, 14 taxa were consistently present across all insect samples, including , , , Acetobacteraceae, , spp., Enterobacteriaceae, spp., spp., , , , , and spp. Minority taxa included spp., , spp., , , spp., , and .

Department of Periodontology, Universitat International de Catalunya, Barcelona, Spain.
Aim: To assess the efficacy of citric acid passivation on implant abutments by evaluating their impact on bacterial load, microbiome composition, inflammatory response, and clinical and radiographic outcomes compared with control abutments over a 12-month follow-up period.
Methods: Implants were placed subcrestally in the posterior sextants and randomly assigned to receive a 2-mm high definitive abutment, either with citric acid passivation (CA group) or without (CTR group). Final restorations were delivered after 12 weeks.

This study investigated the antimicrobial efficacy of a cell-free supernatant (CFS) and live cells from a mixture of Limosilactobacillus fermentum strains (139, 296, and 263). These strains are candidates for probiotic use and were evaluated against five STb virotype enterotoxigenic Escherichia coli (ETEC) strains. Antagonistic activities of L.
