Extracellular

Pseudomonas reactans secretes versatile secondary metabolites, providing protection from parasites and pathogens.
Natural Enemy Resistance Pathogen Resistance

Bacteria

Burkholderia symbiont RPE75 purL mutant resulted in significantly smaller host body size, likely due to a lower infection density in the host midgut.

Sulcia muelleri

Bacteroidota
Bacteria

Sulcia muelleri provisions host insects with essential amino acids that their hosts cannot synthesize.
Amino Acid Provision

Burkholderia

Pseudomonadota
Bacteria
Intracellular and Extracellular

Burkholderia (in Riptortus pedestris) induces specific antimicrobial activity in region MB4 of the midgut, suggesting symbiont-mediated induction of the activity.
Antimicrobial Activity

Regiella insecticola

Pseudomonadota
Bacteria
Intracellular

Candidatus Regiella insecticola protects pea aphids from the aphid-specific fungal entomopathogen Zoophthora occidentalis but not from the generalist insect fungal pathogen Beauveria bassiana.
Pathogen Resistance

Sodalis glossinidius

Pseudomonadota

Glossina palpalis

Cameroon, Angola, B…

Bacteria
Extracellular

Sodalis glossinidius is associated with a three-times greater probability of the host flies being infected by trypanosomes (i.e., this symbiont may facilitate pathogen infection rather than confer resistance).
Pathogen Resistance

Bacteria and Fungi
Intracellular and Extracellular

The hindgut lumen prokaryotic microbiota (Bacteria and Fungi) enables the termite host to thrive on recalcitrant lignocellulosic diets through nutritional symbioses with gut-dwelling prokaryotes and eukaryotes.
Cellulose Hydrolysis

Bacteria
Intracellular

Candidatus Uzinura diaspidicola can provision essential amino acids without a reciprocal bacterial partner.
Amino Acid Provision

Klebsiella pneumonia

Pseudomonadota
Bacteria
Extracellular

Klebsiella pneumonia provides nitrogen fixation to hosts, which is beneficial for desert environments.
Nitrogen Fixation

2013
Regiella

Pseudomonadota
Bacteria
Intracellular

Regiella (in Acyrthosiphon pisum) protects against the entomopathogen Pandora neoaphidis by reducing mortality and decreasing fungal sporulation on dead aphids.
