Special Issue Information

Dear Colleagues,

Conventional antibiotics have been in use for several decades and have saved millions of lives in both humans and animals. However, due to the emergence of antibiotic-resistant bacteria, the application of antibiotics has been restricted or banned. Recently, C. perfringens has been classified as one of the major foodborne pathogens in the United States. Antibiotics had been used by the poultry industry to control necrotic enteritis (NE) caused by Clostridium perfringens, but the ban of antibiotic use in poultry has not only increased the incidence of NE but has also increased the incidence of foodborne outbreaks caused by C. perfringens, making it pivotal to develop alternatives to control the pathogen. Several research groups are involved in the discovery of novel alternative approaches to control bacterial/viral pathogens in various environments including livestock, aquaculture, and poultry, which are reservoirs for several foodborne bacterial pathogens.

The aim of this Special Issue is to provide a collection of articles that showcase current issues and the research addressed by the title, “Advances on Alternatives to Conventional Antimicrobials: Implications on Livestock, Aquaculture, and Poultry Production”. As Guest Editor of this Special Issue, I invite you to submit original research articles, review articles, and short communications related to the control of bacterial or viral pathogens in animals, birds, and aquatic 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 papers will be 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. Animals 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 1800 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.

The purpose of this research was to characterize the antibiotic resistance patterns of Campylobacter spp. isolated from commercial farrow to finish farms in Greece, and analyze the relevant molecular resistance mechanisms among the resistant Campylobacter isolates. Susceptibility testing to five different classes of antibiotics was performed in 100 C. coli and 100 C. jejuni, previously isolated and identified. All isolates were found susceptible to meropenem. Very high rates of resistance were recorded for tetracyclines (84.5%), medium rates of resistance were recorded regarding quinolones (23%), and low and very low rates of resistance were identified for macrolides such as erythromycin and aminoglycosides (12% and 4%, respectively). Only 12.5% of the Campylobacter isolates displayed MDR. Regarding the molecular mechanisms of resistance, all ciprofloxacin resistant isolates hosted the mutant type Thr-86-Ile region of the quinolone resistance-determining region (QRDR) of the gyrA gene. In all erythromycin resistant isolates, the transitional mutations A2075G and A2074C in the 23S rRNA gene were only amplified. Molecular screening of tetracycline resistance genes indicated that the vast majority of Campylobacter isolates (92.3%) were positive for the tet(O) gene. In summary, these findings and especially the very high and medium rates of resistance for tetracyclines and fluroquinolones, respectively recommend that a continuous monitoring of Campylobacter isolates susceptibility in combination with the proper use of antimicrobials in livestock production is of great importance for public health.
