Two membrane filter media (mADA/0129 and mSA/0129 agars) for enumeration of motile Aeromonas in seawater.
Sewage-contaminated natural seawater was analysed for the presence of motile Aeromonas by two membrane filtration procedures. Incubation of membranes on two modified media (mADA (0/129) and mSA (0/129) were compared. The specificity of the two media was high, 95.8% on mADA (0/129) and 94.8% on mSA (0129). The most frequent species identified were A. caviae, followed by A. hydrophila and A. sobria. Motile Aeromonas counts were high in both media (greater than 10(4)/100 ml) and no significant differences were observed between them. The two membrane filtration procedures allowed rapid quantitative recovery of motile Aeromonas from seawater in the presence of very large numbers of competing microflora.
