Abstract

Brucella abortus is an important zoonotic pathogen that infects cattle and buffaloes. In Italy the application of eradication programs combined with vaccination has greatly contributed to reduce the incidence of brucellosis. However, despite the eradication programs brucellosis continue to persist with a high endemicity in some areas of Italy including the province of Caserta. In the present study the genomes of 44 B. abortus strains isolated from different outbreak cases that affected the province of Caserta were sequenced to characterize the genetic diversity of the Brucella strains circulating during the period from 2017 to 2022. The relatedness among these isolates was compared to 52 publicly available genomes of Italian B. abortus isolates. The results highlighted a low genetic diversity in the B. abortus population present in the Caserta area with the persistence of a low number of Brucella lineages and suggests a reduction in circulating lineages in recent years due to eradication programs.

期刊介绍： Veterinary Microbiology is concerned with microbial (bacterial, fungal, viral) diseases of domesticated vertebrate animals (livestock, companion animals, fur-bearing animals, game, poultry, fish) that supply food, other useful products or companionship. In addition, Microbial diseases of wild animals living in captivity, or as members of the feral fauna will also be considered if the infections are of interest because of their interrelation with humans (zoonoses) and/or domestic animals. Studies of antimicrobial resistance are also included, provided that the results represent a substantial advance in knowledge. Authors are strongly encouraged to read - prior to submission - the Editorials (''Scope or cope'' and ''Scope or cope II'') published previously in the journal. The Editors reserve the right to suggest submission to another journal for those papers which they feel would be more appropriate for consideration by that journal. Original research papers of high quality and novelty on aspects of control, host response, molecular biology, pathogenesis, prevention, and treatment of microbial diseases of animals are published. Papers dealing primarily with immunology, epidemiology, molecular biology and antiviral or microbial agents will only be considered if they demonstrate a clear impact on a disease. Papers focusing solely on diagnostic techniques (such as another PCR protocol or ELISA) will not be published - focus should be on a microorganism and not on a particular technique. Papers only reporting microbial sequences, transcriptomics data, or proteomics data will not be considered unless the results represent a substantial advance in knowledge. Drug trial papers will be considered if they have general application or significance. Papers on the identification of microorganisms will also be considered, but detailed taxonomic studies do not fall within the scope of the journal. Case reports will not be published, unless they have general application or contain novel aspects. Papers of geographically limited interest, which repeat what had been established elsewhere will not be considered. The readership of the journal is global.
