| Subset |
| Morphology | Pasteuria |
| CELLULAR |
| Staining | Gram positive |
| Morphology | dichotomously branching, septate mycelium. terminal hyphae enlarge to form sporangia and eventually endospores. |
| Motility | non motile |
| Specialized structures |
| Division |
| COLONIAL |
| Solid surface | Vegetative colonies shaped like cauliflower florets or elongated grapes in clusters or small elongated clusters. daughter colonies are formed by fragmentation. The colonies are first observed in the host's musculature |
| Liquid | colonization of the hemolymph is extensive |
| Growth Parameters | Pasteuria |
| PHYSIOLOGICAL |
| Tropism | |
| Oxygen | |
| pH | |
| Temperature | forms endospores resists desiication |
| Requirements | requires invertebrate host |
| Products | |
| Enzymes | |
| Unique features | host is completely utilized by the bacteria. in the end the host is a bag of bactrial endospores |
| ENVIRONMENTAL |
| Habitat | HAS not been cultivated axenically but can be grown in the laboratory with the invertebrate host |
| Lifestyle | parasite |
| Pathogenicity | parasite on plant-parasitic nematodes of the genera Pratylenchus and Meloidogyne |
| Distribution | field soils and bottoms of ponds host range is restricted. Pasteuria ramosa is found in water fleas, Pasteuria penetrans sensu stricto is found in Meloidogyne incognita and Pasteuria thornei is found iin Ptraylenchus brachyurus |
