Aflatoxin B1(AFB1) is a common contaminant in cereals of global concern， and long-term low-dose exposure can adversely affect human health. Here， we showed that populations with dietary patterns characterized by high-fat diet (HFD) might have an increased risk of exposure to high levels of AFB1. Our data indicated that chronic exposure of AFB1 induced “gut-liver axis” injury in mice under HFD and normal diet (ND) patterns. AFB1 further aggravated hepatic and intestinal injury， and intestinal microbiota disruption in HFD mice. Bifidobacterium breve BAA-2849 intervention analysis showed that liver injury and lipid disorders caused by AFB1 exposure were alleviated by regulating the proportions of different gut microbes. We demonstrated through a mice model that the populations with a dietary pattern of HFD might be more susceptible to AFB1 exposure and adverse effects on the gut-liver axis， and the toxicity of AFB1 exposure can be alleviated by regulating the gut microbiota.

Background Opisthorchiid flukes, particularlyOpisthorchis viverrini,Opisthorchis felineus,Clonorchis sinensis, andMetorchis spp. are the most common fish-borne zoonotic human liver flukes (hLFs). Liver fluke infections are more prevalent in resource-deprived and underprivileged areas. We herein estimated the prevalence of the metacercariae (MC) of major hLFs in common large freshwater fishes (lFWF) marketed for human consumption from some selected areas of Bangladesh along with detection of their molluscan vectors and *** The current status of fish-borne zoonotic hLF infections in lFWF was investigated along with their molluscan vectors and mammalian reservoir hosts in Mymensingh and Kishoreganj in Bangladesh from July 2018–June 2022 using conventional and multiple molecular techniques, such as PCR, PCR-restriction fragment length polymorphism (RFLP), sequencing, and bioinformatic analyses. The infection rate of fishes was analyzed using theZ-test and the loads of MC were compared using the chi-squared (χ2) *** The MC ofC. sinensis,Opisthorchis spp., andMetorchis spp. were detected in 11 species of common and popular lFWF. In lFWF, the estimated prevalence was 18.7% and the mean load was 137.4 ± 149.8 MC per 100 g of fish. The prevalence was the highest (P 0.05) distributed between the head and body of fishes. The infection rate was slightly higher in cultured (19.6%) fishes. The MC ofC. sinensis,O. felineus,O. viverrini, andMetorchis orientalis in fishes were confirmed using PCR, PCR-RFLP and bioinformatics. The cercariae of opisthorchiid (Pleurolophocercus cercariae) flukes were only recovered fromBithynia spp. (3.9%, 42 out of 1089). The ova of hLFs from dogs (4.3%, 5 out of 116) and cats (6.0%, 6 out of 100), and adult flukes (***) from ducks
