Chryseobacterium

Bacteroidota
Bacteria
Extracellular

Chryseobacterium is part of the mosquito midgut community, but its specific function related to CHIKV infection in Aedes aegypti requires investigation.

Blattabacterium

Bacteroidota
Bacteria
Intracellular

Blattabacterium endosymbionts directly or indirectly influence the composition of other bacterial populations by reducing microbial diversity within the host, Supella longipalpa.

Bacteroides

Bacteroidota
Bacteria
Extracellular

The presence of Bacteroides is part of the gut microbiota that enhances the compatibility of the invasive pest (Hyphantria cunea) to new host plants, facilitating rapid adaptation.

Bacteria
Intracellular

Blattabacterium cuenoti serves as the obligate endosymbiont and primary nutritional provider, contributing to amino acid provision and affecting uric acid storage in Blattella germanica.
Amino Acid Provision

2024
Bacteria

Candidatus Walczuchella possesses genes for essential amino acid biosynthesis, suggesting it provides key nutrients to its host, Icerya aegyptiaca.

Candidatus Sulcia

Bacteroidota
Bacteria
Intracellular

Candidatus Sulcia is an obligate endosymbiont that synthesizes essential amino acids to supplement the nutritionally-poor phloem sap diet of its host, Euscelidius variegatus.
Amino Acid Provision

2023
Bacteria

Candidatus Cardinium reduces the competitiveness of the host Bemisia tabaci by decreasing its detoxification metabolism ability, specifically the expression of uridine 5'-diphospho-glucuronyltransferase and P450 genes. However, Cardinium also suppresses the host plant's defense response, a function which may benefit the whiteflies.
