👉 Ectotrichophyton is a genus of bacteria that primarily inhabit soil, often in association with other microorganisms and plants. They are characterized by their large number of microfilaria (microspores) on their cells, which can be up to 20 million cells per spore. Ectotrichophyton is known for its ability to colonize a wide range of environmental conditions, including nutrient-poor soil and acidic pH environments.
