Prevalence of Clostridium difficile and Clostridium perfringens in Swiss horses with and without gastrointestinal disease and microbiota composition in relation to Clostridium difficile shedding

The objective was to provide prevalence data of Clostridium difficile and Clostridium perfringens in horses with and without gastrointestinal disease in Switzerland, and investigate microbiota differences between C. difficile shedders and non-shedders.Fecal samples were taken from healthy horses (n = 103), horses with colic (n = 98) and horses with diarrhea (n = 151). Colic horses were sampled on three days. Selective enrichment culture and molecular typing for C. difficile and C. perfringens was performed. Microbiota differences between horses with colic shedding (n = 7) and not shedding (n = 7) C. difficile were assessed using metagenomic sequencing.The cumulative prevalence (19% C. difficile; 16% C. perfringens) was higher compared to single day samples (1-10% C. difficile; 3-8% C. perfringens, all p

Conclusion This study confirms the in vitro antibacterial activity of BIOCITRO® against Gram-negative and Gram-positive bacteria. For most of the strains, the product reached the bactericidal effect at the same concentration of the bacteriostatic effect and maximum difference between MIC and MBC was two dilution steps. The less susceptible species of the study were S. enterica ssp. enterica and E. coli with MBC90 values of 256 and 128 μg/mL, respectively, while the most susceptible was C. perfringens with MBC90 of 16 μg/mL. After short exposition time to the product, the significant effect over the viability of ...

This study provides new insight into the characterization of foodborne C. perfringens and highlights the potential of WGS for the investigation of FBOs. Introduction Clostridium perfringens is a Gram-positive, spore-forming, anaerobic, rod-shaped bacterium, known as an important causative agent of foodborne and non-foodborne gastroenteritis (Grass et al., 2013). The ability of this bacterium to form resistant spores contributes to its survival in many environmental niches, including soil, sewage, foods, and the intestinal microbiota of humans and animals (Xiao, 2014; Li et al., 2016). C. perfringens can cause necro...

Authors: Khademi F, Sahebkar A Abstract Clostridium species are ubiquitous and associated with various diseases in animals and humans. However, there is little knowledge about the prevalence of their resistance to antibiotics in Iran. Therefore, the aim of this study was to determine the prevalence of antibiotic-resistant Clostridium species in Iran through a meta-analysis of eligible studies published up until December 2018. Fourteen articles on the drug resistance of Clostridium species in Iran were included in the current study following a search in PubMed, Scopus and Google Scholar databases using relevant keyw...

Alfieri, R.M.C Guedes, F.C.F LobatoAbstractNeonatal porcine diarrhea (NPD) is a current problem on pig farms and is caused by several enteropathogens. Among them, Clostridioides difficile stands out due to its importance in piglets and zoonotic potential. A non-toxigenic strain of C. difficile (NTCD), named Z31, was previously tested in hamster and piglet experimental models as a strategy to prevent C. difficile infection (CDI). To evaluate the capacity o...

Abstract The microbial risk involved with natural food fermentation is largely unknown. Here, we report the prevalence of enteric bacterial pathogens in the traditional fermented foods marketed in Northeast region of India. A total of 682 samples of 39 food types (broadly categorized into fermented soybean, bamboo shoot, fish, milk and pork products) collected over four different seasons from seven states of India were analyzed in this study. Cultivation-independent analysis by MiSeq amplicon sequencing of V4-V5 region of the 16S rRNA gene showed the bacterial community structure in the foods. Among the WHO priori...

One of the most potentially harmful aspects of genetically-modified crops, or GMOs, are that such crops are often engineered to be resistant to specific herbicides or pesticides. A farmer therefore can spray an herbicide to kill weeds, while the GM crop plant survives. But it means that the plant now has herbicide residues in it. Or it may contain its own built-in pesticide such as Bt toxin, expressed by the plant because the gene for this pest-resistant compound has been spliced into the plant’s genetic code. So GMO crops pose a double-whammy: the crop itself with new genetically-programmed components, especially pr...

The indolchromin structures were elucidated mainly by their 1D and 2D NMR spectra with the former confirmed by the single-crystal X-ray crystallographic analysis. Each indolchromin alkaloid was chirally separated into four isomers, whose absolute configurations were assigned...
