- Results indicate that while ST8 shows low overall variation and stability across different environments, it can still acquire antimicrobial resistance genes, highlighting the need for ongoing surveillance of non-human sources to better understand its epidemiology.
Background: Human brucellosis is a neglected disease transmitted to humans from animals such as cattle, goats, dogs, and swine. The causative agents are bacteria of the genus , intracellular pathogens usually confined to the reproductive organs of their animal hosts causing sterility and abortions. The objective of the study was to determine the seroprevalence of brucellosis among women with spontaneous abortions (SAW) and compare this seroprevalence with that of healthy pregnant women (HPW).

- - The study investigates genetic diversity and antibiotic resistance in bacteria causing bovine mastitis, a disease that leads to significant economic losses in dairy farming, particularly focusing on isolates from 17 farms in Thuringia, Germany.
- - Out of 40 collected isolates, 75% were found to be methicillin-resistant, showing high resistance rates against several antibiotics like penicillin and tetracycline, while exhibiting susceptibility to others like linezolid and vancomycin.
- - The isolates were categorized into five sequence types, with the majority being ST398, and shared resistance genes linked to antibiotic resistance, highlighting the need for targeted interventions in dairy farming practices.

- - Brucellosis, caused by Brucella spp., is a disease prevalent in Greece, but cases are likely under-reported, and there's limited knowledge about the genetic diversity of the bacteria.
- - Researchers sequenced the genomes of 44 Brucella isolates from humans and animals in Greece, revealing various sublineages, including a novel subgenotype linked to Greek strains, with most isolates believed to have local origins.
- - The study highlights the presence of multiple persistent Brucella foci in Greece and emphasizes the need for improved sampling efforts to better track and understand outbreaks of the disease.

The genomic epidemiology and resistome structure of 46 clinical isolates were studied using whole-genome sequencing. The isolates were chosen based on reduced susceptibility to at least three classes of antimicrobial compounds and were initially identified using MALDI-TOF/MS, followed by polymerase chain reaction amplification of genes.

- Bacteria from the genus Brucella cause brucellosis, a serious disease affecting both animals and humans, and have been controversially merged with other unrelated bacterial species based on genomic findings.
- Researchers argue this merger is inappropriate due to lack of thorough phylogenetic analysis and exclusion of expert opinions in brucellosis.
- They warn that combining these groups could lead to confusion and risks in public health, particularly impacting those dealing with brucellosis in under-resourced regions, and call for keeping the Brucella genus distinct.
