Histopathological Changes in Teleost Kidney as Indicators of Aetiopathogenic Involvement

Abstract

Pathogenic invasion acts as one of the most important aspects of loss of livestock in aquacultural practice across the globe. Different aetiological agents show peculiar differential effects on the vital organs of the fishes and thus are easily detectible through the histological studies of those affected organs. Studies have shown progressive histological changes in fish kidney including changes in the glomerulus as well as the nephric tubules due to pathogenic effect. This review tries to highlight the importance of histological methodologies as the modern instrument of disease diagnosis as well as gives off non-biased information by different authors, that act as both synergistic and antagonistic to each other varying with species and environmental changes. Moreover, comparative gradual changes and the alteration of the function of kidney via pathogenic infestation have also been discussed in detail with relevant case history.
