Antibiotic-susceptible

Antibiotic-susceptible refers to the state of a microorganism, such as bacteria, being vulnerable and inhibited or killed by an antibiotic. This means that the antibiotic is effective against the specific organism, and its presence will prevent or halt the growth and replication of the microorganism. Susceptibility testing, a laboratory procedure, determines whether a particular antibiotic is effective against an identified pathogen. Factors like the antibiotic's mechanism of action and the organism's genetic makeup play vital roles in this interaction. When a microorganism is antibiotic-susceptible, the prescribed medication is expected to clear the infection.

Antibiotic-susceptible meaning with examples

• The laboratory results confirmed that the *Staphylococcus aureus* infection was Antibiotic-susceptible to penicillin, meaning the drug was effective. The physician adjusted the patient's treatment plan immediately to include this course of antibiotics. The patient quickly responded to the antibiotics and showed a steady improvement during the following week of treatment. His doctor was very happy and prescribed him to continue the treatment for the next 5 days.
• The urine culture revealed *Escherichia coli* (E. coli) that was Antibiotic-susceptible to ciprofloxacin. The infectious disease specialist chose this specific antibiotic. The patient's urinary tract infection (UTI) was effectively treated. The patient began feeling better within 24 hours. Her fever broke overnight as the antibiotic fought the infection.
• During the outbreak of *Streptococcus pneumoniae*, it was crucial to identify whether the bacteria remained Antibiotic-susceptible to common first-line antibiotics. Rapid testing showed that most isolates were susceptible. The health authorities were thus able to provide effective treatment to the affected communities. The hospital quickly contained the outbreak from spreading any further to the public.
• The doctor decided to administer a broad-spectrum antibiotic initially until the culture results came back. It was found that the bacteria were Antibiotic-susceptible to azithromycin. This allows the healthcare team to make a more targeted antibiotic prescription. The patient made a good recovery and was released earlier than expected.
