Surface Composition and Temperature Interact to Shape Viral Survival and Growth.
Surface chemistry and temperature interact non-linearly to influence viral survival and growth, with copper at 37°C causing rapid inactivation of bacteriophages T4 and φX174.
- Why it matters: Understanding how environmental factors affect viral persistence is crucial for controlling virus transmission and predicting outbreak risks, yet the combined effects of surface type and temperature remain poorly characterized.
- What they did: The study examined the survival and growth of two bacteriophages on copper, stainless steel, and polypropylene surfaces at 4°C and 37°C, using linear modeling and correlation analyses to assess interactions.
- The result: Findings reveal that surface and temperature effects are non-additive and can decouple viral stability from growth, providing insights into environmental conditions that shape viral fitness outside hosts.
