A researcher is testing the efficacy of a new antiseptic against Staphylococcus aureus. They inoculate broth tubes containing variou concentrations of the chemical. After incubation, it is observed that there is no growth in the undiluted and 1:4 dilutions of the antiseptic. The 1:8, 1:16 and 1:32 c had bacterial growth. Which of the following would indicate that the antiseptic is bacteriostatic? A zone of inhibition appears at the top of the tubes where growth was originally observed. O Subcultures from the original cultures containing the undiluted chemical and the 1:4 dilution do NOT grow in fresh media. Subcultures from the original cultures containing the 1:8, 1:16, and 1:32 dilutions all show growth in fresh media. O Subcultures from the original cultures containing the undiluted chemical and the 1:4 dilution show growth in fresh media.
