Is Corynebacterium Xerosis spore forming?

What does Corynebacterium cause?
Diphtheria is a serious infection caused by strains of bacteria called Corynebacterium diphtheriae that make toxin (poison). It can lead to difficulty breathing, heart failure, paralysis, and even death. CDC recommends vaccines for infants, children, teens, and adults to prevent diphtheria.

They are ubiquitous and can be found on the skin and in the upper respiratory and gastrointestinal tracts. The primary pathogen in this group is Corynebacterium diphtheriae, the etiologic agent of diphtheria. Additional corynebacteria include 45 species, 30 of which on rare occasion cause human disease.
Is Corynebacterium xerosis harmful to humans?

What is Corynebacterium xerosis endocarditis?
Corynebacterium xerosis endocarditis Bacterial endocarditis due to Corynebacterium xerosis developed in a previously healthy person.

There are few reports of diphtheroid endocarditis on intact valves …
