Pseudonocardia is a genus of bacteria belonging to the Pseudonocardiaceae. In is part of the Actinobacteria phylum, often growing in soils with PH 7. They are known for their beneficial symbioses with eukaryotes[1], however their survival does not rely on other organisms[2].

They can be found in terrestrial and aquatic ecosystems, in locations such as the forest soils of China[3] and Thailand[4] as well as the Eucalyptus trees in Australia[5]. They commonly live mutualistically on the cuticle of the leafcutter ants[6] and in crypts on the propleural plate. The antibiotic properties of these bacteria protect the ants and the fungus they grow from disease[7][8]. In return, the host provides the bacteria with nutrition to support their survival[8].

Under the microscope, these bacteria appear to be shapes as rods that branch out, similar to a root system of a tree in appearance[9].
