Antibiotic use in dentistry 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. Bacteraemia is a condition in which bacteria are present in the blood and may cause disease, including systemic disease such as infective endocarditis. Some dental treatments may cause bacteraemia, such as tooth extractions, subgingival scaling or even simple aggressive tooth brushing by
Antibiotic use in livestock common foods harboring these pathogens. There is evidence that a large proportion of resistant "E. coli" isolates causing blood stream infections in people are from livestock produced as food. When manure from antibiotic-fed swine is used as fertilizer elsewhere, the manure may be contaminated with bacteria which can infect humans. Studies have also shown that direct contact with livestock can lead to the spread of antibiotic-resistant bacteria from animals to humans. Sampling of retail meats such as turkey, chicken, pork and beef consistently show high levels of Enterobacteriaceae. Rates of resistant bacteria in these meats are high as well. Sources
