Clostridium baratiiRANK: Species
TAXONOMY: Terrabacteria group -> Firmicutes -> Clostridia -> Clostridiales -> Clostridiaceae -> Clostridium -> Clostridium baratii
'Clostridium baratii' is an anaerobic, motile, gram-positive bacterium. It is a rare cause of infant botulism, in which newborns or infants lose their muscle tone, and develop trouble feeding due to a difficulty in breathing, which can be fatal. Newborns can recover spontaneously or as in two known cases improve with injected botulism antitoxin. , the environmental source of this bacterium is unknown, despite extensive investigations when cases have occurred. The diagnosis must be suspected based on the constellation of symptoms. Clostridium baratii infection is proven when it is grown on a petri dish and isolated from a stool culture. This takes a minimum of 48 hours and more, because the bacterium needs to grow in the absence of oxygen, that is under anaerobic conditions. Associated with inflammation and autoimmune disease.
This species has been identified as a resident in the human gastrointestinal tract based on the phylogenetic framework of its small subunit ribosomal RNA gene sequences.[PMC 4262072]
