The Critical Role of Environmental Synergies in the Creation of Bionanohybrid Microbes
A wide range of bacteria can synthesize surface-associated nanoparticles (SANs) through exogenous metal ions reacting with sulfide produced via cysteine metabolism, resulting in the emergence of a biological-nanoparticle hybrid (bionanohybrid). The attached nanoparticles may couple to extracellular …
Characterization of a Clostridioides difficile outbreak caused by PCR ribotype 046, associated with increased mortality
This study describe a large nosocomial outbreak of Clostridioides difficile infections (CDI) dominated by ribotype (RT) 046 in a Swedish hospital. The aim of the present study was to examine the pathogenicity of this RT, explore epidemiological links by whole genome sequencing (WGS) and evalu …
A Case Report and Review of the Literature: Reactive Arthritis Caused by Clostridioides difficile ribotype 027
With an annual incidence of 250-300 per 100,000 inhabitants, reactive arthritis is not uncommon. However, the fact that Clostridioides difficile infection (CDI) can also lead to this complication is largely unknown. We report on a 69-years-old man who developed reactive arthritis of his right …
Unique Features of Alarmone Metabolism in Clostridioides difficile
The "magic spot" alarmones (pp)pGpp, previously implicated in Clostridioides difficile antibiotic survival, are synthesized by the RelA-SpoT homolog (RSH) of C. difficile (RSHCd) and RelQCd. These enzymes are transcriptionally activated by diverse environmental stresses. RSH …

The incidence of rec CDI is ⬆️. After an initial episode, ⤴️35% have recurrence. ⤴️60% who have a recurrence have another one. Exposure to antibiotics is a critical modifiable risk factor. Most cases occur within 2 wks of antibiotic Rx. #CDiff #antibiotics #antibioticstewardship pic.twitter.com/NTgwYohGZ0— Satyendra Dhar MD FHM🕊(𑆱𑆠𑇀𑆪𑆼𑆁𑆢𑇀𑆫 𑆣𑆫) (@DharSaty) March 2, 2022
Delayed Diagnosis of Clostridium difficile Colitis in a 48-Year-Old Woman with a Homozygous Mutation of the UGT1A1 Gene While on Chemotherapy for Colorectal Carcinoma
BACKGROUND There are many causes of chronic colitis and diarrhea, including the effects of chemotherapy. Mutations in the UGT1A1 gene can be associated with increased toxicity from irinotecan-based chemotherapy. This report is of a case of delayed diagnosis of Clostridium difficile (C. difficile) co …
Clostridioides difficile from brazilian hospitals: characterization of virulence genes by whole genome sequencing
Clostridioides difficile (CD) is the most frequent cause of healthcare related diarrhea and its severity has increased in the last decade by the spread of hypervirulent strains. Most important CD virulence factor is toxin production; however, not only toxins are responsible for Clostridioides virule …
Genetic and phenotypic characteristics of Clostridium (Clostridioides) difficile from canine, bovine, and pediatric populations
Growth rates and relative cytotoxicity of isolates were significantly higher and lower, respectively, in bovine-derived isolates compared to pediatric- and canine-derived isolates. Analysis of core genes showed clustering by host species, though in a few cases, human strains co-clustered with canine …
