Presumptive identification of enterococci from other D streptococci by a rapid sodium chloride tolerance test. 1979

S M Qadri, and M J deSilva, and S G Qadri, and A Villarreal

Ability of enterococci to cause severe disease in humans and their relative resistance to chemotherapeutic agents necessitate their differentiation from other group D streptococci. We developed and evaluated a medium that differentiates enterococci from other group D streptococci within 4 to 24 hours. The 410 clinical isolates used in this study consisted of 328 strains of enterococci and 82 strains of other group D streptococci. The method showed 100 percent sensitivity and specificity with the conventional sodium chloride test. It is simple, reliable, and rapid.

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

D012965	Sodium Chloride	A ubiquitous sodium salt that is commonly used to season food.	Sodium Chloride, (22)Na,Sodium Chloride, (24)NaCl
D013291	Streptococcus	A genus of gram-positive, coccoid bacteria whose organisms occur in pairs or chains. No endospores are produced. Many species exist as commensals or parasites on man or animals with some being highly pathogenic. A few species are saprophytes and occur in the natural environment.
D013293	Enterococcus faecalis	A species of gram-positive, coccoid bacteria commonly isolated from clinical specimens and the human intestinal tract. Most strains are nonhemolytic.	Streptococcus Group D,Streptococcus faecalis
