Discussion

Analysis reveals significant genetic diversity of Wolbachia strains in Anopheles gambiae complexes, indicating ecological implications.

The study found a higher prevalence of Wolbachia infection in Anopheles coluzzii (25.84%) than in Anopheles gambiae s.s. (12.42%), revealing species-specific infection rates.
Phylogenetic analysis identified different clones of a Wolbachia strain named wAnga_CI within the Anopheles gambiae complex, suggesting low genetic divergence.
Overall, 74.57% of Anopheles gambiae s.s. and 21.73% of Anopheles coluzzii were identified as infected with Wolbachia in Côte d’Ivoire.
The findings emphasize the importance of understanding the genetic diversity of Wolbachia strains and their implications for malaria transmission dynamics.

Yao et al. (2025) studied this question.
