BACKGROUND: The mosquito microbiome plays a crucial role in vector competence and disease transmission dynamics, yet comprehensive metatranscriptomic analyses of Anopheles species microbiomes remain limited, particularly in malaria-endemic regions like the Menoreh Hills of Central Java, Indonesia. This study aimed to characterize the microbial and viral community compositions of five Anopheles species and their potential implications for vectorial capacity.
METHODS: Metatranscriptomic analysis was performed on five Anopheles species (An. barbirostris, An. flavirostris, An. kochi, An. maculatus, and An. vagus) collected from the Menoreh Hills endemic area using RNA sequencing, taxonomic classification, and functional annotation approaches.
RESULTS: Proteobacteria emerged as the dominant bacterial phylum across all species, with variations in relative abundance of other taxa. Baculoviridae emerged as the overwhelmingly dominant viral family across all species, with other families including Bunyavirales, Herpesvirales, and Nucleocytoviricota present at much lower abundances. Diversity indices revealed An. vagus with the highest microbial diversity and An. barbirostris with the lowest. Adherence-related virulence factors were predominant, particularly in An. maculatus and An. vagus, while carbohydrate-active enzymes AA1 and GT35 were abundant across all species.
CONCLUSIONS: This study examines microbiome and virome across five Anopheles species from Menoreh Hills. Betabaculovirus dominated virome, while bacterial and fungal communities showed species-specific patterns. Analyses revealed virulence differences. Study limitations include pooled samples. The results provide data for malaria research.
