Comamonas spp are a Gram-negative proteobacterial symbiont which parasitizes Spirocerca lupi.

These proteobacteria are intimately involved in their lifecycle and has recently been targeted as a possible treatment method to target eradication of this parasite[2].

Species which are involved with Spirocerca is thought to be Comamonas testosteroni, a normal digestive bacteria found within many bacteria-feeding nematodes[3].
