Special Issue Information

Dear Colleagues,

“One Health” is an integrated unifying approach that aims to achieve optimal health outcomes while recognizing the interconnectedness of people, animals, plants and their shared environment. The assumptions of this concept are close to microbiologists who understand the role microorganisms play in human and animal health. Therefore, there is a constant need to deepen knowledge about bacteria inhabiting animals, both pathogenic and non-pathogenic. This is particularly important in times of intensification of animal production and the resulting greater susceptibility of animals to diseases, including those caused by bacteria. Controlling bacterial infections in animals involves the use of antimicrobial substances, which in turn contributes to the development of drug resistance in bacteria. Resistant strains spread in the natural environment and may be transmitted to humans and other animals through direct contact or the food chain. Of particular concern are multidrug-resistant zoonotic pathogens, which pose a global threat, causing infections that are difficult to treat and can even lead to death. However, the source of resistance genes may also be non-pathogenic bacteria colonizing the mucous membranes of animals. Monitoring the occurrence of resistant bacterial strains in animals, combined with elucidating resistance mechanisms and transmission routes, is the basis for developing preventive measures. The second important issue of the "One Health" concept is improving the health of animals and controlling their bacterial infections through the use of alternative methods to antibiotics and chemotherapeutics. Probiotics, postbiotics, bacteriophages and natural substances other than antibiotics are becoming more and more common in animal breeding. We welcome manuscripts on the comprehensive phenotypic and genotypic characterization of bacteria from livestock, companion and wild animals, as well as from food of animal origin, with a special focus on zoonotic pathogens. We will pay attention to studies on antimicrobial susceptibility of bacteria and their mechanisms of resistance and virulence, and horizontal transfer of resistance genes. Work on natural and safe methods of combating pathogenic and opportunistic bacteria will also be welcomed, including research on the characterization of potential probiotic strains of animal origin. Manuscripts concerning the following subtopics are especially encouraged:

  • Zoonotic bacteria – prevalence, phenotypic and genotypic characteristics;
  • Antimicrobial resistance - resistance mechanisms and the molecular environment of resistance genes (plasmids, transposons and other integrative conjugative genetic elements);
  • Natural animal microflora as a source and vector of resistance genes;
  • Animal – human transmission;
  • Bacterial virulence traits, pathogen adaptation;
  • In-depth analysis of bacterial characteristics obtained by whole-genome sequencing (WGS)
  • Phylogenetic relationship between bacteria isolated from animals and humans;
  • Probiotics - characteristics of new probiotic strains isolated from animals;
  • Alternative methods of combating pathogenic and opportunistic bacteria found in animals.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
