Epidemiology
Since they are commonly found in soils and in microbiota of humans and animals, Clostridia wounds and infections are found worldwide. Host defenses against the microbe are nearly absent, and very little innate immunity exists, if any. Clostridia can be diagnosed by recognizing the characteristics of the lesion of the infection along with Gram stains of the tissue and bacterial culture.[1] Although the body does not have adequate defenses alone, this microbe can be controlled with the help of antibiotics, like penicillin, and tissue debridement for the more severe cases.[citation needed]
Clostridia and mental health
Clostridia bacteria are commonly found in the
Patients that have been subjected to fecal microbiome transplants to treat their CDI have seen improvements in their mood and mental health.[12] This preliminary research seems to suggest a tentative link between the presence of Clostridia in the gut microbiome and overall mental health, with gut microbiome transplants as an avenue of future research into novel treatments for certain psychiatric disorders.[citation needed]
