Bacteria
Extracellular

Enterococcus mundtii actively secretes a stable class IIa bacteriocin (mundticin KS) against invading bacteria, but not against other gut residents, facilitating the normal development of host gut microbiota.

Wigglesworthia

Pseudomonadota
Bacteria
Intracellular

Wigglesworthia up-regulates the expression of odorant binding protein six in the gut of intrauterine tsetse larvae, which regulates hematopoietic pathways during tsetse’s larval development.

Hamiltonella defensa

Pseudomonadota
Bacteria

Hamiltonella defensa attenuates the systemic release of volatiles by plants after aphid attack, reducing parasitic wasp recruitment and increasing aphid fitness.

Spiroplasma

Mycoplasmatota
Bacteria

The absence of Spiroplasma led to a significant preference by wasps for plants previously attacked by aphids without this symbiont.
Natural Enemy Resistance

Serratia symbiotica

Pseudomonadota
Bacteria

The absence of a single naturally occurring isolate of Serratia symbiotica led to a significant preference by wasps for plants that had been fed on by aphids without the symbiont.
Natural Enemy Resistance

Rickettsiella sp.

Pseudomonadota
Bacteria

The absence of a single-injected isolate of Rickettsiella sp. also led to an attraction of wasps to plants fed on by aphids without secondary symbionts.
