What is the ideal temperature range for the recovery of M. marinum?

• A. 24°C-26°C
• B. 30°C-32°C
• C. 42°C-44°C
• D. 44°C-48°C

Answer: (B)

The ideal temperature range for the recovery of Mycobacterium marinum is indeed between 30°C and 32°C. This species of mycobacteria is a slow-growing organism that typically thrives in cooler temperatures, often found in aquatic environments or associated with fish. Culturing M. marinum at this temperature range allows for optimal growth and recovery in laboratory settings, which is crucial for isolating the organism from environmental samples or diagnosing infections in humans. In contrast, temperatures outside this ideal range can negatively influence growth rates, leading to insufficient recovery or misinterpretation of results. Culturing at temperatures that are too low might slow down growth significantly, while temperatures that are too high can be detrimental, leading to the death of the organism or stressed growth conditions. Thus, maintaining the appropriate temperature is essential for successful isolation and analysis of M. marinum.
