Bacteriological studies on aeromonas infections of Nile tilapia (Oreochromis niloticus) in fish farms in Alexandria Governorate [electronic resource].

Includes references.

A history of sever mortalities and morbidities among cultured Oreochromis niloticus in many different freshwater fish farms in Alexandria province were reported. Clinical observation, postmortem changes as well as bacteriological isolation and identification revealed the presence of Aeromonas hydrophila in 60% of the examined fish samples. Both intramuscular and intraperitoneal inoculation of Aeromonas hydrophila in 20 apparently healthy Oreochromis niloticus fish induced the previously observed clinical signs and re-isolation of the injected pathogen were done. Isolated Aeromonas hydrophila were found to be highly sensitive to Oxytetracyclin and sulphamerazine.
