| Endosymbionts of insects | Wolbachia |
| Endospores | Clostridium |
| Anaerobic, gram-negative, slender rods with pointed ends | Fusobacterium |
| Filamentous bacteria that produce most of our commercial antibiotics | Streptomyces |
| Gram positive cocci that form grapelike clusters | Staphylococcus |
| Gram positive cocci that are aerotolerant anaerobes | Streptomyces |
| Cause of cat-scratch disease | Bartonella |
| Cause of melioidosis | Burkolderia |
| Many of these are plant pathogens, causing plant soft-rot diseases | Erwina |
| Infetious by elementary bodies | Chlamydia |
| Filamentous bacteria, aerobes; cell wall resembles myobacteria; often stain acid-fast | Nocardia |
