Five selective media were evaluated for their effectiveness in the primary isolation of Aeromonas spp. from human patients with acute diarrhea and from healthy domestic animals. Sheep blood agar with 30 mg of ampicillin per liter (ASBA30) yielded a significantly higher percentage of positive specimens as compared with the four other media. The effective combination of two selective media with which 98% of all isolates were detected and with which all of the three human-associated Aeromonas spp. could be isolated was ASBA30-DNase-toluidine blue agar. ASBA30 was the most sensitive medium since it permitted more growth of Aeromonas colonies and effectively suppressed competing microflora. We recommend the use of ASBA30-DNase-toluidine blue agar for investigations in which an attempt is made to assess the significance of Aeromonas spp. in the etiology of human diarrhea.

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
D003967	Diarrhea	An increased liquidity or decreased consistency of FECES, such as running stool. Fecal consistency is related to the ratio of water-holding capacity of insoluble solids to total water, rather than the amount of water present. Diarrhea is not hyperdefecation or increased fecal weight.	Diarrheas
D005243	Feces	Excrement from the INTESTINES, containing unabsorbed solids, waste products, secretions, and BACTERIA of the DIGESTIVE SYSTEM.
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000208	Acute Disease	Disease having a short and relatively severe course.	Acute Diseases,Disease, Acute,Diseases, Acute
D000333	Aeromonas	A genus of gram-negative, facultatively anaerobic, rod-shaped bacteria that occurs singly, in pairs, or in short chains. Its organisms are found in fresh water and sewage and are pathogenic to humans, frogs, and fish.
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D000829	Animals, Domestic	Animals which have become adapted through breeding in captivity to a life intimately associated with humans. They include animals domesticated by humans to live and breed in a tame condition on farms or ranches for economic reasons, including LIVESTOCK (specifically CATTLE; SHEEP; HORSES; etc.), POULTRY; and those raised or kept for pleasure and companionship, e.g., PETS; or specifically DOGS; CATS; etc.	Farm Animals,Domestic Animals,Domesticated Animals,Animal, Domestic,Animal, Domesticated,Animal, Farm,Animals, Domesticated,Animals, Farm,Domestic Animal,Domesticated Animal,Farm Animal
