TI  - Histopathological Evaluation of Zebrafish (Danio rerio) Intestinal Tissue After Imidacloprid Exposure
AB  - The use of pesticides has been increasing day by day to increase productivity in agriculture. Pesticides used in theagricultural area mix into the aquatic ecosystem through rains and groundwater etc. and it threatens the life of aquaticorganisms. Nowadays, one of the most used pesticide group is neonicotinoids. Imidacloprid is the most well known in thisgroup. In this study, it was aimed to observe the histopathological effects of imidacloprid in zebrafish intestinal tissue. Adultzebrafish individuals were administered imidacloprid in concentrations of 9.5, 19, and 38 mg.L-1for 5 days. When tissues areexamined under light microscopy, deterioration of villi morphology, degeneration in brush border structure of epithelial cells,hyperplasia in Goblet cells, and enterocytes due to inflammation, enlargement, and disintegration in lamina propria weredetected. Also, hypertrophy of the smooth muscle cells and thickening in the muscularis externa layer were observed.Dysplasia was detected in the small intestine tissues in samples belonging to the highest concentration group.
