Abstract

HISTOCHEMICAL STUDIES ON GILLS OF THE FRESHWATER MURREL FISHES CHANNA STRIATUS AND CHANNA PUNCTATUS (BLOCH) INFECTED WITH BACTERIAL AND FUNGAL STRESS INDUCED EPIZOOTIC ULCERATIVE SYNDROME (EUS)

ABSTRACT

Histochemistry has contributed a great deal not only to the understanding of biological phenomenon but also to clinical medicine. Histochemical techniques help to analyze not only the localization of protein, lipid and glycogen etc, but also molecular changes at cellular level. The main advantage of histochemistry lies in the analysis of biological phenomena in the "particular cells". The present investigation deals with the histochemical nature of the gills of Channa striatus and Channa punctatus infected with bacteria Aeromonas hydrophila, Pseudomonas aeruginosa and fungi like Aspergillus flavus, Fusarium solani, Rhizophus stolenifer and Penicillium chrysogenum in order to discuss, the comparison between the control and infected gills. In the freshwater fishes of gills are the important organs for respiration and osmoregulation. The gills in a number of fishes show considerable modification with changes in oxygen environment and function in combination with other respiratory structures in the exchange of gases. The indiscriminate use of insecticides in agriculture on variety of crops, pollutants the surrounding water resources, such as lakes and rivers seriously damage of the aquatic fauna. The intake of pollutants variously affect the fish, the gills become more exposed because of their location and constant intimate contact with the water and are liable to damage by any irritant material.
