Hypothesis
This study aims to investigate the gene mutations associated with permethrin resistance in head lice collected from primary school children in Istanbul (Türkiye) and Nagarkot (Nepal).
Conclusion
The study found that gene mutations associated with permethrin resistance are common in head lice samples from Istanbul and Nagarkot, indicating a need for new treatment options.
Supporting Evidence
- High mutation rates were identified in the lice from Istanbul.
- The T917I mutation was not found in lice from Nepal.
- Almost 60% of lice in a previous study remained alive after exposure to permethrin.
Takeaway
This study shows that many head lice in Istanbul and some in Nepal have changes in their genes that make them resistant to a common treatment called permethrin.
Methodology
The study involved collecting head lice samples from school children, isolating DNA, and using PCR to assess gene mutations related to permethrin resistance.
Limitations
The study was limited by the lack of biochemical testing for active permethrin resistance in the collected samples.
Participant Demographics
Children aged 6–12 years from primary schools in Istanbul, Türkiye, and Nagarkot, Nepal.
