The close balance between Cutibacterium acnes and the skin flora, particularly between C. acnes phylotypes, has been suggested to play an important role in the onset of acne. C. acnes has been classif...
The present study investigated the impact of erythritol on the growth of C. acnes strains classified into different RTs and attempted to elucidate the molecular mechanisms underlying its effects....
Culturing tests were performed on several RTs of C. acnes with or without erythritol. A transcriptional analysis of HM554 (RT6) and HM514 (RT5) was also conducted....
The growth of RT2 and RT6, RTs associated with healthy skin, was significantly promoted in a medium containing 10% (W/W) erythritol, whereas that of RT1, RT3, RT4, RT5, and RT8, RTs associated with th...
Erythritol inhibited the growth of RTs associated with acne and promoted that of RTs associated with healthy skin. The enzyme encoded by g3pD may play an important role in the metabolism of erythritol...
The ribotyping of Clostridioides difficile is one of the basic methods of molecular epidemiology for monitoring the spread of C. difficile infections. In the Czech Republic, this procedure is mainly a...
The epidemiology of Clostridioides difficile infection (CDI) has undergone many changes since the beginning of this century and continues to evolve based on recent studies. Here, we performed a molecu...
221 C. difficile isolates were cultured from stool samples of hospitalized patients with diarrhea and screened by PCR for the presence of the toxin A (tcdA), toxin B (tcdB), the binary toxin (cdtA and...
Thirty-five different PCR ribotypes were identified. The most common RTs identified were: 181 (36%, 80/221), 017 (10%, 21/221), 126 (9%, 19/221), 078 (4%, 9/221) and 012 (4%, 8/221). Notably, the pred...
Multiple C. difficile ribotypes have been circulating in the northern Greece region with RTs 181 (closely related to 027), 017, 126 and 078 being predominant....
Autophagy is a homeostatic process that can promote cell survival or death. However, the exact role of autophagy in Clostridioides difficile infection (CDI) is still not precisely elucidated. Here, we...
We report a patient case of pseudomembranous colitis associated with a monotoxin-producing Clostridioides difficile belonging to the very rarely diagnosed polymerase chain reaction (PCR) ribotype (RT)...
Illumina short-read sequencing was performed on n = 11 RT151s from various geographical regions to study their genomic characteristics and relatedness. Subsequently, we used PacBio circular consensus ...
We found that 1) RT151s are polyphyletic with isolates falling into clades 1 and cryptic clades C-I and C-II; 2) RT151 contains both nontoxigenic and toxigenic isolates and 3) RT151 C-II isolates cont...
This study shows that RT151 encompasses both typical and cryptic clades and provides conclusive evidence for C. difficile infection due to clade C-II isolates that was hitherto lacking. Vigilance towa...
To investigate the epidemiology of Clostridioides difficile infection (CDI) in Slovakian hospitals after the emergence of ribotype 176 (027-like) in 2016....
Between 2018 and 2019, European Centre for Disease Control and Prevention CDI surveillance protocol v2.3 was applied to 14 hospitals, with additional data collected on recent antimicrobial use and the...
The mean hospital incidence of CDI was 4.1 cases per 10,000 patient bed-days. One hundred and five (27.6%) in-hospital deaths were reported among the 381 cases. Antimicrobial treatment within the prev...
The newly-predominant RT176 and endemic RT001 are driving the epidemiology of CDI in Slovakia. In addition to fluoroquinolones, the use of macrolide-lincosamide-streptogramin B antibiotics can represe...
Clostridioides difficile is the leading cause of nosocomial diarrhea with high morbidity and mortality worldwide. C. difficile strains produce a crystalline surface layer protein A (SlpA), which is an...
Surface layer protein A (SlpA), the primary outermost structure of Clostridioides difficile, plays an essential role in C. difficile pathogenesis, although its interaction with host intestinal cells a...
C. difficile SlpA from selected RTs variably downregulated the expression level of TJs-assassinated genes and increased the expression level of TLR-4 and pro-inflammatory cytokines in HT-29 treated ce...
The results of the present study highlighted the importance of SlpA in the pathogenesis of CDI and C. difficile-induced inflammatory response in the gut. Further studies are required to unravel the si...
Data from the past decade indicates that Clostridioides difficile infection (CDI) is not only a nosocomial infection but is also increasingly recognized as a disease in the community....
We aimed to study community-onset (CO) CDI in the various age groups in south Serbia with its clinical characteristics, risk factors and microbiological characterization....
The study group included 93 patients with CO-CDI (median age 62). The control group consisted of 186 patients with community-onset diarrhea and stool samples negative tested for CDI....
Of all CDI cases diagnosed with a community onset, 74.19% had a previous contact with a healthcare facility in the previous 12 weeks, but 34.40% have no record on hospitalization in the previous 12 mo...
Patients with CO-CDI had frequently contact with healthcare facility in the previous 12 weeks. Restriction of antacid usage and of high-risk antibiotics in the community may help reduce the incidence ...
