In the light of the morphology, nutrient demands,growth characteristics, and biochemical reactions of them, they belong to A.hydrophila and A.sobria respectively.Drug-sensitivity tests show that the strains were sensitive to amikacin, cefoperazone, Ceftriaxon and Gentamicin. When these drugs were used to treat diseased...
