Agar dilution antimicrobial susceptibility tests were carried out against recent clinical isolates of Yersinia enterocolitica biotype 4, serotype O:3. Aminoglycosides and co-trimoxazole were the most active drugs. All isolates were resistant to ampicillin, carbenicillin, cloxacillin, and erythromycin.

Yersinia enterocolitica, a bacterial enteropathogen that produces a variety of clinical manifestations in humans, includes six biotypes (B), called 1A, 1B, 2, 3, 4 and 5 and about 70 serotypes. The biotypes exhibit diverse pathogenic potential; while 1B and 2-5 may show ability to produce clinical symptoms due to the presence of chromosomal and plasmid (pYV) virulence genes, B1A is supposed a non-pathogenic biotype since it lacks pYV plasmid. Therefore, although B1A strains cause diarrhea in humans, their pathogenic potential has not yet been extensively studied.

This prospective pilot study examined the association between microorganisms and knee osteoarthritis by identifying pathogens in the synovial membrane, synovial fluid, and blood samples from two patients with primary bilateral knee osteoarthritis, using metagenomic next-generation sequencing (mNGS). Intraoperatively, during routine knee arthroplasty procedures, we collected the following 12 samples from each patient: two synovial membrane samples, two synovial fluid samples, and two venous blood samples. After DNA isolation and library construction, each sample was subjected to deep whole-genome sequencing using the DNBSEQT17 platform with the read length PE150 as the default.

Non-nutritive sweeteners (NNS) are widely employed in foodstuffs. However, it has become increasingly evident that their consumption is associated with bacterial dysbiosis, which, in turn, is linked to several health conditions, including a higher risk of type 2 diabetes and cancer. Among the NNS, stevia, whose main component is rebaudioside A (rebA), is gaining popularity in the organic food market segment.

This study aimed to conduct a preliminary investigation in eight Sardinian fermented sausage (SFS) production plants to acquire knowledge about the differences in the applied technological process and their influence on the safety and sensory characteristics of the finished product. Two audits were conducted in each plant to evaluate structural characteristics and process technologies; 72 samples of SFS at the end of seasoning and 48 environmental samples were analyzed. , spp.

Physicians should have a high index of suspicion for the diagnosis of HH when approaching a patient with yersiniosis in the setting of high ferritin levels and increased iron saturation. Yersiniosis serves as a precursor for the diagnosis of HH.
