Antibiotic sensitivity culture the bacteria. This can help in the diagnosis. Once a culture is established, there are two possible ways to get an antibiogram: Once the MIC is calculated, it can be compared to known values for a given bacterium and antibiotic: e.g. a MIC > 0,06 µg/ml may be interpreted as a penicillin-resistant "Streptococcus pneumoniae". Such information may be useful to the clinician, who can change the empirical treatment, to a more custom-tailored treatment that is directed only at the causative bacterium. Often clinical specimens are sent to the clinical laboratory for culture and sensitivity (C&S), which is culture and
Antibiotic prophylaxis background, training, nurse and pharmacist influences, medication supply, and logistics. The American Heart Association (AHA) now recommends antibiotic prophylaxis for very few patients since only a small number of cases of endocarditis might be prevented by this procedure. Antibiotic prophylaxis in domestic animal feed mixes has been employed in America since at least 1970. Over time, the use of antibiotics for growth promotion purposes in livestock was discovered. In 1986, some European countries banned the use of antibiotics because of research they found that linked antibiotic use in livestock and drug resistant bacteria in humans. The European Union regulated in
