clostridium argentinense clostridium argentinense clostridium argentinense is an anaerobic, motile, gram-positive bacterium. some bacilli now identified as cl. argentinense were previously classified as either cl. subterminale, cl. hastiforme, or cl. botulinum toxin group g, respectively. clostridium argentinense scientific classification domain: bacteria phylum: bacillota class: clostridia order: eubacteriales family: clostridiaceae genus: clostridium species: c. argentinense binomial name clostridium argentinensesuen et al. 1988 like cl. botulinum, cl. argentinense produces botulin, a neurotoxin that causes botulism in susceptible mammals. among this proteolytic species' products are acetic acid, butyric acid, isobutyric acid, isovaleric acid, and hydrogen sulfide. cl. argentinense is also asaccharolytic (i.e., unable to metabolize carbohydrates).
