Chapter 22, Problem 1CA

The source of Legionella causing hospital-acquired pneumonia has been linked to hospital water supplies. In healthcare settings, hot water coming out of the faucet should not be hotter than 40.6 ° C to prevent scalding skin. However, Legionella can grow if incubated at that temperature. The CDC recommendation for hot water storage (in a hot water heater) is significantly higher. Using the DRT values below, determine how long it would take to kill 10 7 Legionella cells at 45 ° C . Heating water is expensive, so what is the minimum temperature (from the data) that you would recommend for hospital water storage? Briefly explain.

The death of Geobacillus stearothermophilus spores is routinely used to assess the effectiveness of sterilization procedures. In this procedure, endospores are exposed to the sterilization process (e.g., autoclaving) and then plated on germination medium. If sterilization has been successful, no growth occurs. This requires about 2 days. Yung and Ponce have developed a new approach that yields results within 15 minutes after sterilization. Their technique is based on the release of dipicolinic acid (DPA) from the spore coat by germinating cells. DPA release is monitored microscopically after endospores are placed in media containing alanine and terbium ion (Tb31). Alanine triggers germination and Tb31 binds DPA, which then fluoresces green when illuminated with UV light. Design an experiment in which this new method could be shown to be as reliable as the culturebased approach. What other sterilization procedures besides autoclaving could this technique be used to monitor?
Below is the colony diameter for each yeast culture grown on PDA and AcA incubated at 35°C measured at Day 7. From the data presented above, what could you observe about the growth of the yeast cultures on PDA and AcA? Cite possible reasons behind this.
