The Adult Aedes aegypti Bacterial Microbiota is Robust to Infection with the Obligate Microsporidian Parasite Edhazardia aedis.

The bacterial microbiota of adult Aedes aegypti remains unchanged despite infection with the microsporidian parasite Edhazardia aedis, which severely impacts mosquito health.

• Why it matters: Understanding how pathogens influence mosquito microbiota is crucial for disease control strategies, as microbiota can affect vector competence and pathogen transmission.
• What they did: Researchers used high-throughput amplicon sequencing of the 16S rRNA gene to compare the microbiota of infected and uninfected female mosquitoes, analyzing community diversity and composition.
• The result: Findings show no significant differences in microbiota diversity, taxa abundance, metabolic profiles, or bacterial load, indicating microbiota stability even under parasitic stress.
