Summary: Gram-positive coccoid bacteria were isolated from the nasal cavities and skin regions of pigs and calves. Phylogenetic analysis revealed that these strains belonged to the genus Macrococcus, specifically a novel species called Macrococcus armenti sp. nov. These strains showed similarities to other Macrococcus species, but DNA analysis confirmed their distinctness.

Summary: This study provides insights into the genomic structure and variability of B. hyodysenteriae ST196, a predominant strain in Switzerland. The results reveal that Swiss B. hyodysenteriae isolates of the same ST may have evolved independently over time by point mutations and acquisition of larger genetic elements. The identification of a novel prophage, pphBhCH20, suggests that horizontal gene transfer events may drive changes in genomic structure.

Summary: This study provides the first description of the features of CP-Kp circulating in Switzerland in both human and non-human settings. Genomic analysis revealed that the emerging high-risk lineages of ST11 and ST307 are often isolated from non-human settings. This study serves as a baseline for future whole-genome sequencing-based One-Health surveillance of CP-Kp and highlights the need for metadata to track dissemination routes between different settings.

Summary: This study sequenced the genomes of Actinobacillus pleuropneumoniae strains of different serotypes and found that the genomes were similar, with differences mainly in genes encoding serotype-specific antigens. The study also identified the presence of transposable elements and CRISPR-Cas systems, suggesting a possible exchange of virulence-related factors through horizontal gene transfer. This research is important for diagnostic tests, vaccine development, epidemiological studies, and monitoring antibiotic resistance and virulence gene evolution in A. pleuropneumoniae.

Summary: OXA-48-type β-lactamases are the most common carbapenemase-type in Enterobacterales in Switzerland, mainly found in Escherichia coli and Klebsiella pneumoniae. Bacteria producing OXA-48-type enzymes are endemic in certain regions, including Europe and North Africa, and frequently cause hospital-acquired infections. Despite the emergence of multiple OXA-48-type variants, the original variant, OXA-48, remains the most prevalent in E. coli. This study describes the epidemiology of OXA-48-producing E. coli isolates submitted to the Swiss National Reference Center for Emerging Antibiotic Resistance (NARA) between January 2019 and December 2020.

Summary: KoC species overproduce OXY beta-lactamases, leading to reduced susceptibility to piperacillin-tazobactam, expanded-spectrum cephalosporins, and aztreonam. Whole-genome sequencing and susceptibility testing were used to characterize 44 KoC strains, showing phenotypic differences between ESBL producers and hyperproducers of OXYs. Only cefepime/cefepime-clavulanate combination disk tests or the double-disk synergy test could accurately distinguish between these two groups.

Summary: In Hungary, a study found that 83% of pig farms and 70% of swine professionals were carriers of Livestock-Associated Methicillin-Resistant Staphylococcus aureus (LA-MRSA). The study highlights the significant increase in the occurrence of LA-MRSA in the swine industry in Hungary, calling for a reassessment of the risk it poses to public health.

Summary: A novel 23S ribosomal RNA methylase gene erm(56) flanked by insertion sequence IS6100 was identified in a Trueperella pyogenes isolated from the abscess of a dog and was also present in another T. pyogenes and in Rothia nasimurium from livestock. It was shown to confer resistance to macrolide, lincosamide, streptogramin B antibiotics in T. pyogenes and E. coli, indicating functionality in both Gram-positive and Gram-negative bacteria. The detection of erm(56) on different elements in unrelated bacteria from different animal sources and geographical origins suggests that it has been independently acquired and likely selected by the use of antibiotics in animals.
