Special Issue Information

Dear Colleagues,

Zoonoses are diseases that are naturally transmitted between vertebrate animals and human beings, either directly (through contact, ingestion, or inhalation) or via fomites or biological vectors when arthropods are involved. Bacterial pathogens are often responsible for zoonotic diseases, many of which have long been recognized, such as tuberculosis, brucellosis, and salmonellosis. Conversely, other zoonoses, such as arthropod-borne diseases, are considered emerging threats. Several animals can be a source of bacterial zoonotic pathogens for humans, including livestock, pets, including unconventional species, and wildlife. Bacterial zoonoses can be aggravated through the increasing problem of antimicrobial resistance. Many bacteria have the ability to acquire and disseminate resistance traits. The interplay among antimicrobial resistance, virulence factors, and mobile genetic elements in the dissemination of these traits highlights the complexity of managing bacterial infections in animal and human populations. This Special Issue will provide new insights into the challenges posed by virulence and antimicrobial resistance in zoonotic bacteria from a One Health perspective. We welcome submissions of both original research and review articles.

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.

Knowledge about the potential roles of pets as reservoirs for plasmid-mediated quinolone resistance is still limited in Türkiye. Thus, in our study, the presence of plasmid-mediated quinolone genes (qnrA, qnrB and qnrS) was examined by multiplex Polymerase Chain Reaction (PCR) in 101 fecal Escherichia coli (Escherichia coli) strains isolated from healthy dogs. Moreover, the relationship between the presence of qnr genes and prevalence of quinolone resistance, extended spectrum beta-lactamase (ESBL) and plasmid replicon types, mostly detected among fecal E. coli isolates (F, K, FIB, N, FIA, FIC, and Y) were investigated. A total of 41 strains (40.6%) carried at least one qnr gene. Qnr genes were found in 38.8% of quinolone-resistant and 40.9% of quinolone-susceptible strains. ESBL production was detected in 27 strains, 10 of which also harbored a qnr gene. Among qnr-positive strains, 19 (46.3%) carried both IncK and IncF plasmids (p < 0.001). IncF plasmids were significantly more prevalent in quinolone-resistant strains than in susceptible ones (p < 0.001), suggesting a potential link between qnr carriage, quinolone resistance, and IncF plasmids. To our knowledge, this is the first study investigating the relationship between qnr genes and specific plasmid replicon types in E. coli from healthy dogs in Türkiye. Our findings suggest that domestic animals may serve as reservoirs for antibiotic-resistant E. coli, underscoring the importance of a One Health approach. Full article
