Special Issue Information

Dear Colleagues,

Mastitis remains one of the most prevalent and economically significant diseases affecting dairy animals worldwide, leading to reduced milk yield, altered milk composition, and increased veterinary costs. This Special Issue, titled “Mastitis in Animals”, aims to provide a comprehensive platform for advancing understanding of the etiology, pathogenesis, prevention, and treatment of mastitis. It welcomes research covering bacterial, viral, and fungal infections, antimicrobial resistance, host–pathogen interactions, and immune responses in different dairy species. Studies on diagnostic innovations, management strategies, and alternative therapies such as probiotics, phytochemicals, or immunomodulators are particularly encouraged. By integrating molecular, clinical, and epidemiological perspectives, this Special Issue seeks to promote sustainable mastitis control and enhance animal welfare and milk quality within modern dairy production systems.

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 250 words) can be sent to the Editorial Office for assessment.

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. Veterinary Sciences is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2100 CHF (Swiss Francs). 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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • Reprint: MDPI Books provides the opportunity to republish successful Special Issues in book format, both online and in print.

Bacterial zoonoses pose a serious threat to the development of animal husbandry, food safety, and public health. Staphylococcus aureus (S. aureus) is a major infectious and food-borne pathogen worldwide, and there was an urgent need to develop relevant methodologies for the control of bacterial infections. This study aimed to evaluate the effectiveness of cell-free supernatants (CFSs) produced by selected strains of Lactiplantibacillus plantarum (L. plantarum), Lacticaseibacillus rhamnosus (L. rhamnosus), Streptococcus thermophilus (S. thermophilus), and Bifidobacterium longum subspecies infantis (B. infantis) to inhibit in vitrogrown S. aureus BNCC 186335. CFSs of S. thermophilus, B. infantis, L. plantarum, and L. rhamnosus not only showed good antibacterial activity against S. aureus but also have strong stability and tolerance, which could destroy the integrity of cell membrane, lead to changes in cell morphology, and then strongly and rapidly kill bacteria. Notably, the primary antimicrobial substances in the CFSs of L. plantarum and L. rhamnosus were organic acids and protein components, whereas the main antimicrobial substances in the CFSs of S. thermophilus and B. infantis were organic acids. Meanwhile, four CFSs achieved substantial removal of biofilms and inhibited decreased ATP content. These findings suggest that the CFSs of S. thermophilus, B. infantis, L. plantarum, and L. rhamnosus may have potential applications as biological preservatives to control the contamination of S. aureus in the food industry and animal husbandry.
