Differentiation of Cariogenic Streptococci by Fluorescent Antibody

Visualization of Horse Sickness virus by the Fluorescent antibody technique

Responses of cariogenic streptococci to environmental stresses.

To persist in the oral cavity, bacteria must be able to tolerate rapid and substantial environmental fluctuations, particularly in pH and nutrient source and availability. Various species of Streptococcus, one of the most abundant genera in the mouth, are associated with oral health, as well as with dental caries. Cariogenic streptococci depend on a biofilm lifestyle for survival and persistenc...

Enterococcus faecium WB2000 Inhibits Biofilm Formation by Oral Cariogenic Streptococci

This study investigated the inhibitory effect of probiotic Enterococcus faecium WB2000 on biofilm formation by cariogenic streptococci. The ability of E. faecium WB2000 and JCM5804 and Enterococcus faecalis JCM5803 to inhibit biofilm formation by seven laboratory oral streptococcal strains and 13 clinical mutans streptococcal strains was assayed. The Enterococcal strains inhibited biofilm forma...

Inhibition of commonantigen fluorescence in grouping streptococci by the fluorescent antibody method.

The fluorescent antibody method of Coons and Kaplan (1950) has led to numerous studies of its practical application, many directed to the problem of rapid and accurate identification of microorganisms (Goldman, 1953, 1957; Moody, Goldman, and Thomason, 1956; Thomason et al., 1956, 1957; LaBrec, Formal, and Schneider, 1959; Winter, and Moody, 1959). Moody, Ellis and Updyke (1958) showed that ser...

Diagnosis of Intestinal Amoebiasis with Indirect Fluorescent Antibody Test

SUMMARY The results of direct stool examination in 102 watery and bloody diarrhea patients were compared with the presence of antibodies against Entamoeba histolytica with Indirect Fluorescent Antibody Test. Besides 22 healthy individuals included in this study as control group. It was found that 22 patients (21.5%) with a sera titre higher than 1/320 bad only 9 (8.8%) positive E. Histolytica ...
