long-term use of orthodontic appliances and fixation ligatures creates a favorable environment for the accumulation of oral normal microflora and increases the risk of enamel demineralization and periodontal disease. the aim of this study was to compare the antimicrobial effects of zataria multiflora extract and 0.2% chlorhexidine (chx) mouthwash on experimentally contaminated orthodontic elast...
The minimal inhibitory concentrations of nine growth-promoting agents were determined by an agar-dilution method against 66 bile-tolerant streptococcal (8 Streptococcus faecalis, 23 Streptococcus faecalis subsp. liquefaciens, 15 Streptococcus faecium, and 20 carboxyphilic streptococci) strains isolated from the ceca of 52 chickens on 19 farms. Avoparcin was equally active on all groups. The nat...
Tetrahydrohomopteroate, which inhibits the growth of Streptococcus faecium (Streptococcus faecalis ATCC 8043), replaces folate as a growth factor in chlorguanide triazine-resistant strains of this organism.
In-vitro sensitivities were performed on 140 specimens of urine which grew Streptococcus faecalis of more than 100 000 organisms/ml between March 1970 and February 1971. Although the combination of trimethoprim and sulphamethoxazole definitely appeared to be more effective than sulphonamide alone and as effective as ampicillin, its use for more than two weeks in 14 cases of uncomplicated urinar...
The following organisms have shown in vitro sensitivity to DBLTM Cefotaxime Sodium for Injection. Gram-positive: Staphylococci spp, including coagulase-positive, coagulase-negative and penicillinase-producing strains. Streptococci spp, including β-haemolytic and other streptococci such as Streptococcus mitis (viridans), Streptococcus pneumoniae. (Many strains of enterococci, e.g. Streptoco...
SYNOPSIS The incidence of trimethoprim resistance in coliforms and multiresistant strains of Staphylococcus aureus isolated in Bristol from 1970 to 1972 is low-2-3 and 1 0% respectively. The resistance is probably intrinsic; there is no evidence that it is R-factor or plasmid mediated. A single mechanism that confers resistance to both trimethoprim and sulphamethoxazole has not been detected. N...
Autoradiograms of total lipid extracts from Streptococcus faecalis ATCC 9790, harvested in the stationary phase from a medium containing (32)P-orthophosphate, showed six major spots. The corresponding compounds were identified as diphosphatidylglycerol (possibly with a penta acyl structure); phosphatidylglycerol; a provisionally identified mixture of alanylphosphatidylglycerol and of the 2'-lys...
