State microbe is noteworthy because it is: the first significant antibiotic discovered after penicillin; the first systemic antibiotic discovered in America; the first antibiotic active against tuberculosis; first-line treatment for plague. Moreover, New Jersey was the home of Selman Waksman, who was awarded the Nobel Prize in Physiology or Medicine for his systematic studies of antibiotic production by "S. griseus" and other soil microbes. On May 15, 2017, Senate Bill 3190 (S3190) was introduced by Senator Samuel D. Thompson (R-12); the bill designates "Streptomyces griseus" as the New Jersey State Microbe, to be added to the state's other state symbols. On June
Antibiotic sensitivity Antibiotic sensitivity Antibiotic sensitivity or antibiotic susceptibility is the susceptibility of bacteria to antibiotics. Because susceptibility can vary even within a species (with some strains being more resistant than others), antibiotic susceptibility testing (AST) is usually carried out to determine which antibiotic will be most successful in treating a bacterial infection in vivo. Testing for antibiotic sensitivity is often done by the Kirby-Bauer method. Small wafers containing antibiotics are placed onto a plate upon which bacteria are growing. If the bacteria are sensitive to the antibiotic, a clear ring, or zone of inhibition, is seen around the wafer indicating poor
