Systemic Absorption of Oral and Rectal Vancomycin in a Critically Ill Patient: A Case Report.

Enteral administration of vancomycin is the standard treatment for () colitis and is presumed to have no systemic absorption. In critically ill patients, however, especially with multi-organ failure, enteral absorption of vancomycin is unpredictable and can cause severe toxicity if it remains unrecognized. We therefore report a case of systemic absorption of enteric vancomycin in a patient with severe colitis.

Clostridioides difficile has rapidly become a major cause of nosocomial infectious diarrhea worldwide due to the misuse of antibiotics. Our previous study confirmed that RT046/ST35 strain is associated with more severe clinical symptoms compared to RT012/ST54 strain. We conducted genome comparison of the RT046/ST35 and RT012/ST54 strains using whole-genome sequencing technology.

The prevalence and persistence of CDI in hospital settings has resulted in an extensive collection of clinical isolates and their classification, typically by ribotype. While much of the current literature focuses on one or two prominent ribotypes ( .

Importance: The natural history of C. difficile progression in nucleic acid amplification test (NAAT) positive, toxin enzyme immunoassay-negative patients remains poorly described. Better understanding risk for subsequent disease may improve prevention strategies.

The human gut microbiome contains many bacterial strains of the same species ("strain-level variants") that shape microbiome function. The tremendous scale and molecular resolution at which microbial communities are being interrogated motivates addressing how to describe strain-level variants. We introduce the "Spectral Tree"-an inferred tree of relatedness built from patterns of co-evolutionary constraint between greater than 7,000 diverse bacteria.
