The agglutination of 218 clinical isolates and three ATCC type strains of "Streptococcus milleri" was tested with 25 different lectins from plants and fungi. An agglutination reaction with one or more lectins was observed with 42 isolates when the cells were untreated. After trypsinisation of the bacteria, 109 strains yielded a positive reaction and after boiling the bacterial cells at pH2, 218 isolates were agglutinated. As an overall result of our experiments with untreated, trypsinised and boiled cells, 17, 37 and 45 different agglutination patterns, respectively, were obtained. The lectins from Datura stramonium, Robinia pseudoacacia and Dolichos biflorus agglutinated isolates belonging only to Lancefield group C, being non-reactive with other isolates. These lectins were also found to be specific for "large colony type" streptococci of group C. The use of lectin agglutination in epidemiological and ecological studies of "S. milleri" is discussed.

D000371	Agglutination	The clumping together of suspended material resulting from the action of AGGLUTININS.
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
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
D013290	Streptococcal Infections	Infections with bacteria of the genus STREPTOCOCCUS.	Group A Strep Infection,Group A Streptococcal Infection,Group A Streptococcal Infections,Group B Strep Infection,Group B Streptococcal Infection,Group B Streptococcal Infections,Infections, Streptococcal,Infection, Streptococcal,Streptococcal Infection
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.
D015203	Reproducibility of Results	The statistical reproducibility of measurements (often in a clinical context), including the testing of instrumentation or techniques to obtain reproducible results. The concept includes reproducibility of physiological measurements, which may be used to develop rules to assess probability or prognosis, or response to a stimulus; reproducibility of occurrence of a condition; and reproducibility of experimental results.

D037102	Lectins	Proteins that share the common characteristic of binding to carbohydrates. Some ANTIBODIES and carbohydrate-metabolizing proteins (ENZYMES) also bind to carbohydrates, however they are not considered lectins. PLANT LECTINS are carbohydrate-binding proteins that have been primarily identified by their hemagglutinating activity (HEMAGGLUTININS). However, a variety of lectins occur in animal species where they serve diverse array of functions through specific carbohydrate recognition.
