[Aeromonas hydrophila in waters of Lake San Roque and its tributaries].
The presence of Aeromonas hydrophila in 72 samples of water of Lake San Roque and two rivers that flow into it, situated in Punilla Valley, Córdoba was investigated. Water-peptone Alkaline (enrichment medium) and Rippey Cabelli Agar without ampicillin (selective and differential medium for Aeromonas hydrophila) were used for isolation. The colonies obtained were assayed by oxidase test and subsequent oxidation-fermentation of Hugh Leifson, motility, urease, mannitol and trehalose fermentation, ornithine and lysine decarboxylation. Voges Proskauer and gas production from glucose and glycerol. Aeromonas hydrophila was isolated in 13% of water samples obtained in days with high temperature. Although this finding is not alarming, its presence should be taken into account because of its potential pathogenesis.
