This research article investigates the effects of nicotine on Borrelia burgdorferi (Bb), the spirochete bacterium that causes Lyme disease. The researchers exposed B. burgdorferi cultures to varying concentrations of nicotine and monitored bacterial viability using viable count methods. The study examined how nicotine influences bacterial growth, survival, and potentially pathogenic properties. Results demonstrated dose-dependent effects of nicotine on B. burgdorferi populations, with specific concentration thresholds affecting bacterial viability. The findings suggest that nicotine exposure can modulate B. burgdorferi survival in laboratory conditions. This work contributes to understanding potential interactions between environmental substances and the causative agent of Lyme disease, with implications for how bacterial pathogens may respond to host-derived or external chemical exposures. The study employed standardized microbiological techniques to ensure reproducibility and included appropriate controls throughout the experimental design.

Key findings

• Nicotine exposure produced dose-dependent effects on B. burgdorferi viability in culture
• Specific nicotine concentrations altered bacterial survival rates compared to control conditions
• The study identified threshold nicotine concentrations that significantly impacted bacterial populations
• B. burgdorferi demonstrated variable responses to nicotine depending on exposure concentration levels
• Results suggest environmental and host-derived substances can modulate Lyme disease spirochete survival
