Clostridioides is a genus of Gram-positive bacteria, which includes Clostridioides difficile, a human pathogen causing an infectious diarrhea.
Taxonomy
The genus Clostridioides was created to describe a few species formerly in the genus Clostridium which have been shown to be their own genetically distinct genus using 16S rRNA gene sequencing analysis.[1] However, both names are still in use and valid under the International Code of Nomenclature of Prokaryotes.[2]
Description
They are obligate anaerobes capable of producing endospores. The normal, reproducing cells of Clostridioides, called the vegetative form, are rod-shaped, which gives them their name, from the Greek κλωστήρ or spindle. Clostridioides endospores, like Clostridium endospores, have a distinct bowling pin or bottle shape, distinguishing them from other bacterial endospores, which are usually ovoid in shape.[citation needed]
