This study investigates the acute and repeated-dose oral toxicity of crude antifungal compounds produced by Lactobacillus plantarum AF1 (Lb. plantarum AF1) and Lactobacillus plantarum HD1 (Lb. plantarum HD1) in male and female Sprague Dawley rats. In the acute toxicity study, crude antifungal compounds (500, 1,000, and 2,000 mg/kg) did not reduce mortality or produce significant changes in general behaviors or the gross appearance of external and internal organs. In the repeated-dose toxicity study, crude antifungal compounds were administered orally to rats at doses of 500, 1,000, and 2,000 mg/kg daily for 28 days. There were no test-article-related deaths, abnormal clinical signs, or body weight changes. In addition, there were no significant differences between groups treated with crude antifungal compounds and the control group in their organ weight, hematological and serum biochemical parameters, or any other factors. These results suggest that the acute or repeated-dose oral administration of crude antifungal compounds produced by Lb. plantarum AF1 plus Lb. plantarum HD1 is not toxic in male and female rats.
