Saccharomyces cerevisiae Sc47 (Biosaf) is a commercially available baker's yeast strain (Lesaffre, France) that has been used as a probiotic in animal nutrition. It has been previously reported that animals fed with the yeast showed an improved resistance to several enteric infectious diseases. Some of the S. cerevisiae strains adhere potentially pathogenic bacteria such as Escherichia coli and Salmonella spp. This could be a mechanism through which animals fed with the yeast may become more resistant to infections caused by these microorganisms. In this paper, the adhesion of forty-five Salmonella spp. isolates to Sc47 was assessed by sedimentation and agglutination tests, and by light and electron microscopy. Results showed that 57.7% (26/45) of the isolates and 66.6% (6/9) of the Salmonella serovars tested adhered to the Sc47 cell wall.

The influx of whole genome sequencing (WGS) data in the public health and clinical diagnostic sectors has created a need for data analysis methods and bioinformatics expertise, which can be a bottleneck for many laboratories. At Sciensano, the Belgian national public health institute, an intuitive and user-friendly bioinformatics tool portal was implemented using Galaxy, an open-source platform for data analysis and workflow creation. The Galaxy @Sciensano instance is available to both internal and external scientists and offers a wide range of tools provided by the community, complemented by over 50 custom tools and pipelines developed in-house.

Evaluation of MALDI-TOF for identification of Vibrio cholerae and Vibrio parahaemolyticus from growth on agar media.

Appl Microbiol Biotechnol

January 2025

Vibrio Reference Laboratory, Bureau of Microbial Hazards, Health Canada, Ottawa, ON, Canada.

Two methods were compared for their ability to accurately identify Vibrio species of interest: whole genome sequencing as the reference method and MALDI-TOF MS (matrix-assisted laser desorption/ionization-time of flight mass spectrometry) proteome fingerprinting. The accuracy of mass spectrometry-based identification method was evaluated for its ability to accurately identify isolates of Vibrio cholerae and Vibrio parahaemolyticus. Identification result of each isolate obtained by mass spectrometry was compared to identification by whole genome sequencing (WGS).

The global spread of antimicrobial resistance is one of the most significant challenges of the 21st century. The waterfowl sector is an economically decisive part of the poultry industry, yet it remains under-researched, and its antibiotic usage is less monitored. Our study aimed to determine the antimicrobial susceptibility of avian pathogenic strains, which are still prevalent in ducks and geese, against antibiotics critical for both animal and human health, and to compare these findings with human resistance data.

Substances of organic origin are seeing increasing use in agriculture as rich sources of nutrients for plants. The aim of this study was to determine the microbiological contamination of sewage sludge and digestate to assess their safe use as fertilizers in Poland. The assessment of microbial soil, sewage sludge and digestate contamination was based on the total number of mesophilic bacteria and Gram-negative bacteria from the family.
