The Effect of a High Monosodium Glutamate Diet in Inducing Changes in Microbiota Diversity and Kidney Pathology in Hamsters Infected with Opisthorchis viverrini
Journal Title: Vajira Medical Journal: Journal of Urban Medicine - Year 2024, Vol 68, Issue 1
Abstract
OBJECTIVE: To investigate the effect of a combination of a high dose of monosodium glutamate (MSG) and chronic Opisthorchis viverrini (O. viverrini) infection on kidney pathology and microbiota changes compared to either factor alone. METHODS: Forty male golden hamsters were divided into four groups (10 hamsters per group): non-infected hamsters fed with standard diet (NC), O. viverrini infected hamsters fed with standard diet (OV), non-infected hamsters fed with high doses of MSG in drinking water (MS), and O. viverrini infected hamsters fed with high doses of MSG in drinking water (OM). After 8 months, fecal samples were collected, DNA extracted and subjected to 16S-rRNA sequencing analysis to determine microbial diversity. Kidneys were also collected for histopathological study. RESULTS: Kidney histopathology showed tubular damages and tubular fibrosis were significantly prominent in the OM group, which showed higher pathology changes than in the OV group or MS groups. Next generation sequencing indicated that the levels of Firmicutes to Bacteroides ratio decreased in the OV group (0.28), MS group (0.43) and OM group (0.43) respectively when compared to control group (0.52). In genus levels, Methanobrevibacter, Ruminococcus_1, Escherichia-Shigella, Bacteroides, Akkermansia and Oligella were abundance in the OM group. CONCLUSION: The changing of gut microbiota distribution and kidney pathology changes were more severe in the cases of O. viverrini infection together with MSG consumption. This study provides a first step towards focusing on diet and parasitic infections.
