Najeeb Parvez and Mudarris MSA

Bacterial Hemorrhagic Septicemia (BHS) was found affecting Cyprinus carpio and Channa striatus. Bacteriological examination and artificial infection trials were carried out on these fishes. Hematological examination showed substantial decline in the number of erythrocytes and lymphocytes, increase in the number of granulocytes and significant loss in the amount of hemoglobin. Histopathological examination suggested that the affected part of the skin had got completely destroyed. The peripheral area of the liver showed loosening of tissue and cell distension. There was complete shrinkage in all the components of kidney and glomeruli appeared smaller in size than healthy ones. Artificially infected specimens of C. carpio and C. striatus were treated with 20 ppm and 30 ppm chloramphenicol solution and oxytetracycline @ 50 and 60 mg/kg of feed for 20 and 30 days respectively. The results of this work indicated that Aeromonas hydrophila and Pseudomonas fluorescens were the etiological agents for this disease.
