Histopathological changes in diseased catfish (Clarias gariepinus) and treated by ciprofloxacin and clove extracts.
Bacteria pathogens may cause a serious loss in aquaculture and also health hazards to humans. On the basis of biochemical characteristics and API-20E system, the highest prevailing isolate was identified as Aeromonas sobria. Infection with A. sobria in African catfish (Clarias gariepinus) induced focal hemorrhage at the end of gill operculum, generalized edema and ulcers on skin surface. Internal signs of infection include hyperemia of the hepatic artery, coagulative necrosis in the liver and hydropic degeneration of renal tubules according to the histopathological examination. In vivo the combination of ciprofloxacin and clove extract was the choice as alternative bacterial therapeutic agents in infected C. gariepinus with A. sobria. Moreover histopathological changes have is the base for the evaluation of fish health.Author(s): Abd El-Salam SS, Ghaly MF, Baraka DM, Mahmoud SH, El-Makhzangy AA
