Clostridium Infections

The grounding supports bacterial infection by Clostridium and related Clostridioides species as the cause. It also indicates that antibiotic exposure can disrupt the gut microbiota and contribute to recurrent Clostridioides difficile infection, but does not support broader causal claims for all Clostridium infections.

The literature links these infections, especially Clostridioides difficile infection, to disruption of the gastrointestinal microbiome. Antibiotics can reduce microbial diversity and alter metabolic activity, which may weaken colonization resistance and allow pathogenic overgrowth.

Antibiotic use is supported as a risk factor because it disrupts gut microbiota and is associated with antibiotic-associated diarrhea and recurrent Clostridioides difficile infection. The grounding does not support additional specific risk factors for the broader disease category.

Treatment is described at the modality level as antibiotic therapy for infection and fecal microbiota transplantation for recurrent Clostridioides difficile infection. The literature also discusses live biotherapeutic products as emerging microbiome-restoring approaches, but FMT is the established microbiome-based treatment highlighted in the grounding.
