Question
Record zones of growth inhibition in mm around each disc. Antiseptic agent dilutions Staphylococcus aureus Escherichia coli Serratia marcescens Mouth wash neat Mouth wash 1:1 Savlon 1:1 Savlon 1:20 Bleach 1:8 Bleach 1:20 Liquid soap 1:10 Liquid soap 1:20 How effective are these agents in controlling growth? Are they still effective at the highest dilution?
Solution
To answer this question, you would need to measure the zones of growth inhibition around each disc in millimeters. This is typically done by placing a ruler or caliper over the petri dish and measuring the diameter of the clear zone around each disc where bacterial growth has been inhibited.
The effectiveness of the antiseptic agents in controlling growth can be determined by comparing these measurements. The larger the zone of inhibition, the more effective the agent is at preventing bacterial growth.
To determine if the agents are still effective at the highest dilution, you would compare the zones of inhibition for each agent at its highest dilution to the zones of inhibition at lower dilutions. If the zone of inhibition is significantly smaller at the highest dilution, this could indicate that the agent is less effective at this dilution.
However, without the actual measurements or any visual data, it's impossible to definitively answer this question. You would need to provide the measurements of the zones of inhibition for each agent and dilution.
