13. Atividade antibacteriana in vitro da clorexidina gel, hidroxido de calcio e associação de ambos utilizados como medicação intracanal em dentina bovina contaminada com Enterococcus faecalis
Recent improvements in endodontic microbiology haves howedt he close relationship between micoorganism and failure of endodontic therapy.The control of endodontic infection is attempted by the observation of the aseptic techniques through out the endodontic therapy, by cleaning and shaping the root canal,by intracanal medication by hermetic filling of the oo

14. Identification of Actinomyces (Corynebacterium) pyogenes with the API 20 Strep system.
A total of 62 strains of Actinomyces pyogenes (previously Corynebacterium pyogenes) were examined by the API 20 Strep system (API System, La Balme Les Grottes, Montalieu-Vercieu, France). The system was shown to be reliable and rapid when the tests were compared with standard identification methods. No confusion occurred with streptococcal profiles in the cu

15. Identification of Gardnerella vaginalis with the API 20 Strep system.
A total of 137 strains of Gardnerella vaginalis were examined by the API 20 Strep system. The system was shown to be reliable when the tests were compared with standard identification methods, and very little confusion occurred with streptococcal profiles; consequently, G. vaginalis has been included in the API 20 Strep data base.

16. Evaluation of the API 20 Strep system for species identification of streptococci isolated from bovine mastitis.
A new commercial system (API 20 Strep) for the species identification of streptococci associated with bovine mastitis was compared with the conventional biochemical methods. A total of 84 strains, including Streptococcus agalactiae (13), S. dysgalactiae (16), S. uberis (24), S. faecalis (12), S. faecium (5), and S. bovis (14) were tested. Using profile index

17. Rapid species identification of group C streptococci isolated from horses.
Two commercial systems, the API 20S (Analytab Products, Plainview, N.Y.) and the Rapid Strep (API System S.A., Montalieu-Vercieu, France), were evaluated for ease of use and accuracy in the rapid identification of group C streptococci isolated from horses. A total of 85 Streptococcus isolates were tested, including S. equi (67 isolates), S. zooepidemicus (13

20. Incidence of penicillin tolerance among blood culture isolates of Streptococcus sanguis, 1987-88.
Laboratories that reported isolations of Streptococcus sanguis from blood cultures to the Communicable Disease Surveillance Centre (CDSC) Colindale were requested to submit strains to Bath Public Health Laboratory to allow the prevalence of penicillin tolerance within different biotypes of this species to be studied. One hundred and fifty one Streptococcus s

21. 16S Ribosomal DNA Sequence Analysis Distinguishes Biotypes of Streptococcus bovis: Streptococcus bovis Biotype II/2 Is a Separate Genospecies and the Predominant Clinical Isolate in Adult Males
We characterized 22 human clinical strains of Streptococcus bovis by genotypic (16S rRNA gene sequence analysis [MicroSeq]; Applied Biosystems, Foster City, Calif.) and phenotypic (API 20 Strep and Rapid ID32 Strep systems (bioMerieux Vitek, Hazelton, Mo.) methods. The strains, isolated from blood, cerebrospinal fluid (CSF), and urine, formed two distinct 16

22. Characterization of nutritionally variant streptococci by biochemical tests and penicillin-binding proteins.
A comparative study of 60 strains of nutritionally variant streptococci (NVS) with 34 strains of Streptococcus mitis and 37 strains of Streptococcus sanguis II showed the presence of a red chromophore which was absent in the other streptococcal species. By using the conventional microbiological tests, only small differences were found between the NVS and the

23. Comparison of Conventional and Molecular Methods for Identification of Aerobic Catalase-Negative Gram-Positive Cocci in the Clinical Laboratory
Over a period of 18 months we have evaluated the use of 16S ribosomal DNA (rDNA) sequence analysis as a means of identifying aerobic catalase-negative gram-positive cocci in the clinical laboratory. A total of 171 clinically relevant strains were studied. The results of molecular analyses were compared with those obtained with a commercially available phenot

24. Identification of Streptococcus sobrinus with monoclonal antibodies.
Identification of Streptococcus sobrinus is often difficult to perform because of the great resemblance of the organism to other oral streptococcal species. Therefore, monoclonal antibodies were prepared which were shown to be highly specific for S. sobrinus. Cross-reactivity with other oral microorganisms has not been observed in an enzyme-linked immunosorb
