We evaluated the extent to which serogroup O:11 Aeromonas strains could be recovered from both clinical and environmental specimens and the cultural parameters that affected the phenotypic marker (autoagglutination) associated with this group. Of over 200 Aeromonas strains screened, serogroup O:11 was identified only among the phenospecies A. hydrophila and A. sobria and was associated with clinical isolates more frequently than with environmental strains. Blood and wound isolates accounted for almost 50% of all O:11 strains identified. The autoagglutination phenotype associated with O:11 strains could be detected in most commercial liquid media, under a wide range of growth temperatures, and within 15 min of incubation at 100 degrees C. The results suggest that clinical laboratories can recognize this important group of Aeromonas strains by two simple tests.

UI	MeSH Term	Description	Entries
D002140	California	State bounded on the east by Nevada and Arizona, on the south by Mexico and the Pacific Ocean on the south and west, and on the north by Oregon.
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
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.
D000372	Agglutination Tests	Tests that are dependent on the clumping of cells, microorganisms, or particles when mixed with specific antiserum. (From Stedman, 26th ed)	Agglutination Test,Test, Agglutination,Tests, Agglutination
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.

D015373	Bacterial Typing Techniques	Procedures for identifying types and strains of bacteria. The most frequently employed typing systems are BACTERIOPHAGE TYPING and SEROTYPING as well as bacteriocin typing and biotyping.
