Order Eubacteriales is a scientific order of bacteria that are commonly found in soil and the digestive tracts of animals. The order is also known by several synonyms such as the "true bacteria," "gram-positive bacteria," or simply "Eubacteria." In recent years, scientists have reclassified the order into several new families, including Actinomycetaceae, Firmicutes, and Clostridiaceae. These changes reflect a growing understanding of the genetic and physiological diversity of the members of this order. Despite this reclassification, the term Eubacteriales remains common in scientific literature and is one of the key orders studied in the field of microbiology.
