Seasonal distribution ofAeromonas hydrophilain river water and isolation from river fish

摘要

The seasonal distribution ofAeromonas hydrophilain water and recovery rate from live river fish was investigated. The highest isolation rates ofA. hydrophilaoccurred in water during the late winter followed by a progressive decline in density during the summer and monsoon seasons. The organism was recovered from fish throughout the period from which it was concluded that they form a reservoir which is unrelated to their density in water. The enterotoxigenicity of some environmental strains was tested in suckling mice and rabbit ileal loop.
