Journal ArticleDOI
Tetracycline resistance and TetM in oral anaerobic bacteria and Neisseria perflava-N. sicca.
TL;DR: Tetracycline-resistant organisms isolated from six patients with periodontal disease included Bacteroides spp, Eubacterium spp.
Journal ArticleDOI
Antibiotic Resistance in Oral/Respiratory Bacteria:
TL;DR: In this review, the main mechanisms of resistance to the important antibiotics used for treatment of disease caused by oral/respiratory bacteria--including beta-lactams, tetracycline, and metronidazole--are discussed in detail.
Journal ArticleDOI
Comparison of Multi-Drug Resistant Environmental Methicillin-Resistant Staphylococcus aureus Isolated from Recreational Beaches and High Touch Surfaces in Built Environments
TL;DR: A surprising 98% of the 55 environmental MRSA isolates were resistant to other classes of antibiotics and most likely represent reservoirs for these genes in the environment.
Journal ArticleDOI
How xylitol-containing products affect cariogenic bacteria.
Marilyn C. Roberts,Christine A. Riedy,Susan E. Coldwell,Sonia I. Nagahama,Kathleen Judge,Malinda Lam,Tarja Kaakko,Jorge L. Castillo,Peter Milgrom +8 more
TL;DR: Overall, consumption of xylitol-containing snacks and candy did not reduce S. mutans levels and Xylitol's mechanism of action can be explained to patients.
Journal ArticleDOI
Amino acid repetitions in the dihydropteroate synthase of Streptococcus pneumoniae lead to sulfonamide resistance with limited effects on substrate K(m).
Ylva Haasum,Katrin Ström,Rahma Wehelie,Vicki A. Luna,Marilyn C. Roberts,Jeffrey P. Maskell,Lucinda M. C. Hall,Göte Swedberg +7 more
TL;DR: The results confirm that the repetitions are sufficient for development of a resistant enzyme and suggest that the fitness cost to the organism of developing resistance may be very low.
