Antibiotic susceptibility and biochemical properties of Streptococcus faecalis strains reacting with both D and G antisera.
نویسندگان
چکیده
Thirty one of 60 consecutive isolates of Streptococcus faecalis produced a reaction in both D and G streptococcal grouping sera. A close correlation was found between this grouping reaction and haemolysin production, resistance to erythromycin, tetracycline, and trimethoprim, and delayed fermentation of sorbitol.

متن کاملSusceptibility of various serogroups of streptococci to clindamycin and lincomycin.
The minimal inhibitory concentration of lincomycin and clindamycin for a large number of strains from multiple serogroups of streptococci was determined. The median minimal inhibitory concentration for streptococci from groups A, B, C, F, G, H, L, and M and nongroupable organisms ranged from 0.02 to 0.39 mug of lincomycin per ml and from </=0.01 to 0.09 mug of clindamycin per ml. Among the grou...
متن کاملDetection of relationships between Streptococcus faecalis and Lactobacillus casei by immunological studies with two forms of malic enzyme.
Antisera prepared against two isologous malic enzymes from Lactobacillus casei strains 64H and M40 were used to survey and categorize the various malic enzymes found within this diverse species. In addition to detecting three major antigenic variants of malic enzyme within this group, both antisera readily reacted with Streptococcus faecalis malic enzyme. The cross-reactions between the L. case...
متن کاملDifferentiation of M. scrofulaceum from Related Mycobacterial Species by Double-Diffusion Technique
Isolation and differentiation of various species of mycobacteria are predominantly based on conventional, cultural and biochemical tests. Among the non-tuberculous mycobacteria, these tests are unable to differentiate M. scrofulaceum from M. avium-intracellulare (MAI) because of their identical biochemical characteristics. For this reason, one hundred mycobacterial strains suspected to be M. ...
