Clostridium ramosum (Vuillemin) comb. nov.: Emended Description and Proposed Neotype Strain

Seventeen strains of organisms which conform to the original and subsequent descriptions of the organism currently known as Ramibacterium ramosum, and which include Prévot's strain 113-I as well as recent isolates, have been shown to produce heat-resistant spores which are often difficult to detect. For this species we propose the name Clostridium ramosum (Vuillemin) comb. nov. (basonym: Nocardia ramosa Vuillemin) and Prévot's strain 113-I (ATCC 25582, VPI 0427) as the neotype. Recently isolated strains were from stitch abscesses, urinary infections, abdominal fluid, rectal abscesses and drainage, perineal drainage, vagina, feces, and sigmoid colon contents. Prévot-collection strains were from appendicitis, colitis, liver abscesses, and feces. Previously undescribed characteristics of this species are presented.
