Animal infection models are essential for understanding bacterial pathogenicity and corresponding host immune responses. In this study, we investigated whether juvenile Xenopus laevis could be used as an model human pathogenic bacteria. frogs succumbed to intraperitoneal injection containing the bacteria Staphylococcus aureus, Pseudomonas aeruginosa, Listeria monocytogenes. contrast, non-pathogenic Bacillus subtilis Escherichia coli did not induce mortality in frogs. The administration of appropriate antibiotics suppressed caused by S. aureus P. aeruginosa. Strains lacking agr locus, cvfA (rny) gene, or hemolysin genes LIPI-1-deleted mutant L. monocytogenes, which attenuate virulence within mammals, exhibited reduced compared with their respective wild-type counterparts. Bacterial distribution analysis revealed that persisted blood, liver, heart, muscles until death. These results suggested induces sepsis-like symptoms frogs, supporting use a valuable animal evaluating antimicrobial efficacy identifying various
