Doctor here. Cultures are taken from blood, urine, CSF, sputum or wherever else. Whatever grows will have something called a MIC which is the minimal inhibitory concentration, which is the minimum amount of the certain antibiotic that is susceptible to the bacteria, etc. hope this helps!

Thanks for the answer, so if I understand it correctly naturally occurring antibodies in his body will be extracted and used to create an injectable antibiotic?

By creating immunotherapy based on our antibodies, we can target MDR bacteria
