In vivo toxicity assessment of the probiotic Bacillus amyloliquefaciens HTI-19 isolated from stingless bee (Heterotrigona itama) honey
This study evaluated the acute and sub-acute toxicity of B. amyloliquefaciens HTI-19 (isolated from stingless bee honey) in female Sprague Dawley rats. In an acute toxicity study, the rats received a low dosage (1 × 109 CFU·mL−1 ), medium dosage (3 × 109 CFU·mL−1 ), or high dosage (1 × 1010 CFU·mL−1...
