A comparison was made of three different growing media already proposed by some authors for the recovery of Aeromonas hydrophila in environmental water samples of various origins. The media tested were Rippey and Cabelli m Aeromonas agar, Rimler-Shotts agar and the Ryan Aeromonas Base Medium with the addition of ampicillin. The efficiency of the three media was evaluated on the basis of the following reference criteria: accuracy, selectivity and specificity. The results obtained, analyzed by calculating the Kendall concordance coefficients, demonstrated that m Aeromonas agar is the most suitable media for quantitative recovery of Aeromonas hydrophila from surface water samples even if a reduction in the total heterotrophic load of 3-logs was never obtained with this medium.

UI MeSH Term Description Entries
D003470 Culture Media Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN. Media, Culture
D005618 Fresh Water Water containing no significant amounts of salts, such as water from RIVERS and LAKES. Freshwater,Fresh Waters,Freshwaters,Water, Fresh,Waters, Fresh
D012623 Seawater The salinated water of OCEANS AND SEAS that provides habitat for marine organisms. Sea Water,Sea Waters,Seawaters,Water, Sea,Waters, Sea
D012680 Sensitivity and Specificity Binary classification measures to assess test results. Sensitivity or recall rate is the proportion of true positives. Specificity is the probability of correctly determining the absence of a condition. (From Last, Dictionary of Epidemiology, 2d ed) Specificity,Sensitivity,Specificity and Sensitivity
D014871 Water Microbiology The presence of bacteria, viruses, and fungi in water. This term is not restricted to pathogenic organisms. Microbiology, Water
D016980 Aeromonas hydrophila A species of gram-negative, facultatively anaerobic, rod-shaped bacteria that may be pathogenic for frogs, fish, and mammals, including man. In humans, cellulitis and diarrhea can result from infection with this organism.
