This user manual provides instructions on how to use the calculator effectively.

Getting Started

To use the MOI Calculator, follow these steps:

  1. Accessing the Calculator: Open the MOI Calculator web page in your internet browser. The calculator can be accessed online through the provided link.
  2. Entering Data: Once the calculator interface is loaded, you will see input fields for entering data related to phages and bacteria.
  3. Input Fields:
    • Number of Phages: Enter the number of phages used in your experiment (in PFU/mL).
    • Volume of Phage Solution: Enter the volume of the phage solution used in milliliters (mL).
    • Number of Bacteria: Enter the number of bacteria used in your experiment (in CFU/mL).
    • Volume of Bacterial Culture: Enter the volume of the bacterial culture used in milliliters (mL).
  4. Calculating MOI: After entering the required data, click the "Calculate" button. The calculator will then compute the Multiplicity of Infection (MOI) based on the provided inputs.
  5. Viewing the Result: The calculated MOI value will be displayed below the input fields. This value represents the ratio of phages to bacteria in your experimental setup.
  6. Interpreting the Result: Use the calculated MOI value to understand the relative abundance of phages and bacteria in your experiment. A higher MOI indicates more phages relative to bacteria, while a lower MOI suggests fewer phages per bacterium.
  7. Adjusting Inputs: If needed, you can modify any of the input values and recalculate the MOI by clicking the "Calculate" button again.

Tips for Effective Use

  • Ensure Accuracy: Enter accurate numerical values for the number of phages, volume of phage solution, number of bacteria, and volume of bacterial culture.
  • Avoid Zero Values: Avoid entering zero values for the number of bacteria or volume of phage solution, as this will result in an error.
  • Repeat for Different Scenarios: Use the calculator for various experimental scenarios by entering different values for phages, bacteria, and volumes.
