Summary: This study investigated the changes in gut microbiota before and after CDI in patients with hepatic cirrhosis. The gut microbial richness and diversity were significantly reduced in CDI patients, with a higher abundance of opportunistic pathogen Enterococcus and a lower abundance of beneficial symbionts. These findings suggest a potential link between intestinal flora imbalance and the development of CDI.

Summary: In recent years, significant progress has been made in the study of the intestinal microbiota, with research moving beyond the laboratory and into clinical applications like fecal microbiota transplantation. Studies have shown interesting associations between imbalances in the intestinal microbiota and disease development, highlighting the potential therapeutic benefits of fecal microbiota transplantation in reversing this process.

Summary: This cross-sectional study assessed the prevalence and risk factors of C. difficile carriage in Dutch veterinary healthcare workers. The results showed a low prevalence of C. difficile carriage in veterinary healthcare workers, with no indications of occupational risk related to working in veterinary care.

Summary: The study found that healthcare providers have relatively low knowledge of FMT, with main concerns being lack of clinical evidence and infection transmission. However, as knowledge increases, willingness to recommend FMT also increases. Strengthening FMT clinical efficacy and reducing infection can enhance its public acceptance, application, and popularity. Further research is required to explore the donor screening procedure.

Summary: This study aimed to determine the incidence rates and epidemiology of Clostridium difficile infection (CDI) in Perth, Western Australia. The results showed a high incidence of CDI, with female patients experiencing a higher risk. The dominant molecular type of CDI was RT 014/020, but there was also high strain diversity, suggesting exposure to multiple reservoirs.

Summary: Retrospective study on 90 cases of equine enterocolitis caused by 5 prevalent agents showed differences in gross and microscopic pathology, with more severe lesions in cases of Clostridioides difficile and Clostridium perfringens. Pseudomembranes were commonly observed in affected intestines, while thrombosis was more prevalent in Paeniclostridium sordellii cases. Overall, the specificity of gross and microscopic lesions for distinguishing these etiologies was limited.

Summary: This in vitro study aimed to assess the effect of a commonly used pre-FMT processing method on the bacterial composition and viability of the fecal filtrate. The results showed that the major bacterial populations in equine feces remained viable when using the described pre-FMT protocol, but the relative abundances of some minor genera were significantly different in the final filtrate.

Summary: The composition and impact of fecal-microbe-derived extracellular vesicles (EVs) in different diseases were studied. Metagenomic profiling of feces and fecal-microbe-derived EVs revealed significant differences in microbial composition between feces and EVs in disease groups. Moreover, fecal EVs from different diseases had varying effects on the permeability of Caco-2 cells.

Summary: This study aimed to evaluate the stability of pigment and lipid and analyze the microbial ecology in beef with an extremely long shelf-life using classical methods and metagenetics. Beef samples from different origins with varying shelf-life were stored at subzero temperature or a-1/+4 degrees C and then subjected to simulated retail distribution. Results showed that subzero storage inhibited the growth of certain bacteria during vacuum aging, while metmyoglobin formation and excessive lactic acid bacteria growth limited the shelf-life during retail distribution. Classic microbiological methods underestimated lactic acid bacteria count, whereas metagenetics identified Carnobacterium maltaromaticum as a main contributor to the long shelf-life of Australian beef.

Summary: Enterotoxigenic Escherichia coli (ETEC) strains causing post-weaning diarrhea in piglets can be effectively treated with bacteriophage therapy. In this study, four bacteriophages were isolated and one of them showed therapeutic potential in vivo against ETEC infection. Furthermore, this phage was found to replicate efficiently both in vitro and in vivo, demonstrating its safety on the piglet microbiota.

Summary: The effect of phage ULIP33 on the intestinal microbiota was assessed using in vitro model. Results showed that the phage did not have a significant impact on the colonic microbiota, suggesting its potential as an alternative treatment against antimicrobial resistance.

Summary: Sepsis is a life-threatening disease caused by an uncontrolled immune response to infection. Due to a lack of predictive biomarkers and pertinent models, early diagnosis and effective treatment are challenging. Experimental models, mostly conducted on mice, have been used to understand the pathophysiology of sepsis and identify potential biomarkers or targets. However, results from these models are difficult to translate to humans. Horses, which naturally develop sepsis, may offer a promising spontaneous model for sepsis research with implications for both human and veterinary medicine.

Summary: In this study, C. difficile carriage and 16S rDNA profiling were assessed in three clinical groups. The results showed significant differences in microbial diversity and relative abundances of certain genera among different clinical groups and between positive and negative C. difficile carriage groups. Moreover, a microbiota footprint was detected in C. difficile-positive carriers.

Summary: In this study, a comprehensive microbial source amplicon database tailored for source tracking in veterinary settings was developed. The database was rigorously tested by examining the composition of resident microbiota in a frequently accessed environment by veterinary students and veterinarians. The study demonstrated the potential for DNA sequence-based source tracking to enrich microbial investigation of potential bacterial contamination sources in veterinary facilities.

Summary: This study aimed to analyze the genetic profile and expression of SE(l)s in Belgian artisanal cheeses, as well as to compare different analytical tools. The results showed that classical SEs were not the dominant type in these cheeses, and all S. aureus isolates carried at least one gene encoding a new SE(l). Some of these new SEs have been implicated in food poisoning outbreaks. Therefore, the development of specific techniques for the investigation of SFP outbreaks is crucial.

Summary: To improve antibiotic treatment during elective caesarean sections, it is necessary to understand the bacterial composition of the surgical site. This study found that bacterial DNA was present in all surgical sites, with Mycoplasma wenyonii being the most commonly identified species. However, not all bacteria cultured were identified through DNA sequencing. Further research is needed to understand the role of these bacteria in post-operative complications and the effect of antibiotic treatment.
