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 misuse a lack of knowledge on which antibiotic use generates the most risk to humans, policies and regulations have been placed to limit any harmful effects, such as the potential of bacteria developing antibiotic resistance within livestock, and that bacteria transferring resistance genes to human pathogens On January 1, 2017, the FDA enacted legislation to require that all human medically important feed-grade antibiotics (many prior over-the-counter-drugs) become classified as Veterinary Feed Directive drugs (VFD). This action requires that farmers establish and work with veterinaries to receive a written VFD order. The effect of this act places a requirement on an established
