Antibiotic use in dentistry an antibiotic which incorporates sulphonamides and trimethoprim. It covers a broad spectrum of activity and in dentistry, is often used where there are clear signs and indications of bacterial infection that is sensitive to cotrimoxazole. This is determined by bacteriological sensitivity tests. Antibiotic use in dentistry There are many circumstances during dental treatment where antibiotics are prescribed by dentists to prevent further infection (e.g. post-operative infection). The most common antibiotic prescribed by dental practitioners is penicillin in the form of amoxicillin, however many patients are hypersensitive to this particular antibiotic. Therefore, in the cases of allergies, erythromycin is used instead.
A22 (antibiotic) A22 (antibiotic) A22, also known as "S"-(3,4-dichlorbenzyl)isothiourea, is a chemical compound with antibiotic activity. It is colorless, hygroscopic, and light-sensitive. A22 acts as a reversible inhibitor of the bacterial cell wall protein MreB, causing bacterial rod-shaped cells to form coccoid cells. The antibiotic activity of A22 has been studied primarily in "Pseudomonas aeruginosa." However, A22 does not seem to be useful as an antibiotic in humans due to its cytotoxic and genotoxic effects on human peripheral blood mononuclear cells (PBMCs). Despite its cytotoxic effects in human cells, A22 has been used as a research tool to investigate the bacterial cytoskeleton.
