Infection due to Clostridium difficile is currently the main cause of hospital acquired gastrointestinal disease. Its prevalence in the elderly population is higher due to there being many associated risk factors in this age group, such as comorbidity, frequent exposure to the healthcare or residential home setting, immunosenescence, greater consumption of antibiotics, and antiacids. The diagnostic techniques have notably improved in the last few years, which could also account for an increase in its diagnosis. The new expert consensus recommendations propose stratifying the clinical situation of the patient in order to choose the treatment option. Therapeutic options have recently been included in the new Clinical Guidelines, such as flidaxomicin or fecal transplants, with encouraging results, particularly for the control of frequent recurrences.

Spore germination in is initiated by a cascade of activities of several proteins that culminates in the activation of SleC, a cell-wall-processing enzyme. We report herein the details of the enzymatic activities of SleC by the use of synthetic peptidoglycan fragments and of spore sacculi. The reactions include the formation of 1,6-anhydromuramate─a hallmark of lytic transglycosylase activity─as well as a muramate hydrolytic product, both of which proceed through the same transient oxocarbenium species.

Genomic data on from the African continent are currently lacking, resulting in the region being under-represented in global analyses of infection (CDI) epidemiology. For the first time in Nigeria, we utilized whole-genome sequencing and phylogenetic tools to compare isolates from diarrhoeic human patients (=142), livestock (=38), poultry manure (=5) and dogs (=9) in the same geographic area (Makurdi, north-central Nigeria) and relate them to the global population. In addition, selected isolates were tested for antimicrobial susceptibility (=33) and characterized by PCR ribotyping (=53).

Unlabelled: Mutations affecting flagellin (FliC) have been shown to be hypervirulent in animal models and display increased toxin production and alterations in central metabolism. The regulation of flagellin levels in bacteria is governed by a tripartite regulatory network involving , , and , which creates a feedback system to regulate flagella production. Through genomic analysis of clade 5 strains (non-motile), we identified they have jettisoned many of the genes required for flagellum biosynthesis yet retain the major flagellin gene and regulatory gene .

Background: is a significant cause of healthcare-associated infections, with rising antimicrobial resistance complicating treatment. This study offers a genomic analysis of , focusing on sequence types (STs), global distribution, antibiotic resistance genes, and virulence factors in its chromosomal and plasmid DNA.

Fever and diarrhea are the common symptoms of infection (CDI); however, pseudomembranous enteritis, megacolonization, and paralytic ileus have been observed in severe cases. spores are resistant to several types of disinfectants. Thus, they are often the causative pathogens of healthcare-associated infections.
