Abstract
The nicotinic acetylcholine receptors (nAChR) in pests' central nervous
systems are the target of neonicotinoids, a class of extensively used
pesticides. Due to their high-water solubility, neonicotinoids have gained
popularity as a result of their ability to penetrate the entire plant when
applied to the soil. The first generation of neonicotinoids, of which
imidacloprid is a member, are widely used in agriculture around the globe. For
environmental contamination, histopathology is a helpful biomarker. A potential
toxicological hazard for fish is the presence of pesticide in the environment
as a result of its widespread usage in agriculture. Assessing histopathological
changes in fish organs in response to organic trace contamination can help in
evaluating the pathological impacts of water-borne pollution. In the present
study, exposure of Clarias gariepinus to Imidacloprid in various
sublethal concentrations resulted in structural alterations like damaged renal
tubule and hematopoietic tissue, tubular shrinkage, severe necrosis and
swelling of lymphocytes, vacuolation of glandular epithelium, swelling of renal
tubule, renal tubule dilation, glomerulus distortion, enlargement of sinusoids,
disorganization of tissues, exudate in tubules, reduction of renal cells,
desquamation of renal epithelium, balloon necrosis, distorted renal tubule. The
effect was time- and dose-dependent.
