Publication year: 2011 Source: Tissue and Cell, Available online 13 October 2011 R. Al-Ghanbousi, T. Ba-Omar, R. Victor Aphanius dispar, a freshwater fish (mean total length ± sd, 3.42 ± 0.33 cm) was exposed to different concentrations of deltamethrin (2.25, 2.50 and 3.00 μg L), an insecticide used to control Dubas bug,Ommatissus lybicusin Oman. The histopathological changes in the structure of the gills in fish exposed to deltamethrin was studied using light, transmission and scanning electron microscopy. In light microscopy, the fish exposed to 2.25 μg Ldeltamethrin, showed hypertrophy and hyperplasia of chloride cells, while in 2.50 μg L, additional changes like vacuolization, lifting of the lamellar epithelium and fusion of secondary lamellae were observed.
