Bacterial septicaemia in silver carp, Hypophthalmichthys molitrix (Valenciennes)
Bacterial septicaemia causing anaemia, emaciation, haemorrhagic lesions on the body, dydrops and mortality in silver carp is described for the first time from India. The causative organism isolated in pure culture from heart, kidney and coelomic fluid of the diseased specimens was characterized as a strain of Aeromonas hydrophila ssp. hydrophila on the basis of its morphology. Gram-staining property and other biochemical reactions. Significantly high levels of haemosiderin deposits were found in liver and ovary. Other marked histopathological changes in the kidney and liver are also discussed. Average haemotocrit value in diseased specimens was 27.63 as compared to 34.5 in healthy specimens. Drug sensitivity tests are also presented.
