Special Issue Information

Dear Colleagues,

Molecular techniques have become a cornerstone of rapid diagnostics in veterinary sciences. Advances in molecular diagnostics—from cloning and polymerase chain reaction (PCR) to Sanger sequencing, Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR), and next-generation sequencing (NGS)—have equipped researchers and clinicians with powerful tools for detecting infectious diseases, including viral, bacterial, and protozoal infections, as well as neoplastic, metabolic-degenerative, and hereditary disorders. Animals—from pets and livestock to wildlife—play an integral role in ecosystems and are deeply connected to human life. Many animal diseases are zoonotic, posing significant threats to public health at the animal–human interface. The threat of transboundary diseases is at an all-time high, with the global spread of high-consequence diseases leading to significant economic losses. The application of highly sensitive and rapid diagnostic technologies ensures the timely detection of diseases, which is essential for effective management and intervention strategies to protect both animal and public health. This Special Issue aims to highlight the latest advancements and applications of molecular diagnostics in veterinary sciences. We welcome you to submit your work, including original research articles and review papers that offer new perspectives on molecular diagnostics for infectious diseases in veterinary medicine.

We look forward to receiving your contributions.

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. Animals is an international peer-reviewed open access semimonthly 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 2400 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.

Accurate pathogen detection in bovine semen is crucial for animal health surveillance and international trade. Semen presents unique challenges due to the presence of PCR inhibitors from seminal plasma and extender components, reducing nucleic acid extraction efficiency and sensitivity. The two National Animal Health Laboratory Network-approved extraction platforms (MagMAX CORE and IndiMag Pathogen Kits) were evaluated using 88 negative extended semen samples at 200 µL input volume, reduced input volumes, and pretreatment strategies with two influenza A virus (IAV) PCR assays, containing different exogenous internal controls (ICs) to assess PCR inhibition. The ICs yielded overall passing rates from 31.8% to 100.0% and varied greatly based on the extender formulation and extraction protocol. Validation continued with naturally infected semen containing Mycoplasma bovis, bovine viral diarrhea virus, bovine herpesvirus-1, and the limit of detection using Mycoplasma bovis. The IndiMag Pathogen 100-na was then selected for evaluation of diagnostic sensitivity and specificity, reproducibility, and detection limits with IAV-spiked samples, using the two IAV PCR assays and their ICs. Selected archived semen samples used in this study were screened and were negative for IAV by both PCR assays. These findings underscore the importance of tailored extraction methods in overcoming semen-associated inhibition and facilitating reliable pathogen surveillance in bovine germplasm. Full article
