Special Issue Information

Dear Colleagues,

The first volume of the Special Issue titled "Bacteria Isolated from Animals: Virulence, Characterization and Antimicrobial Resistance" was recently released. As the topic is still relevant in terms of both animal and human health, its exploration will be continued in the second volume. Antimicrobial use in animals contributes to the emergence of resistant strains of bacteria that can be transferred to humans through the food chain or direct contact. Of particular concern are multidrug-resistant strains of pathogenic bacteria called "Superbugs", which pose a global threat by causing infections that are difficult to treat and even lead to death. Monitoring the occurrence of resistant bacterial strains, especially pathogenic ones, combined with explaining the mechanisms of resistance is the basis for developing recommendations for infection control and rationalizing the use of antimicrobial substances in animal husbandry. These tasks are part of the European One Health Action Plan against antimicrobial resistance (COM/2017/0339).

We welcome studies 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. Researchers are encouraged to publish studies on the drug susceptibility of bacteria and their mechanisms of resistance and virulence, as well as studies on alternative methods of controlling bacterial infections in animals. We also accept studies on the antibiotic susceptibility of non-pathogenic bacteria inhabiting the mucous membranes of animals or food of animal origin. Such bacteria, while not causing infection, maybe a reservoir of resistance genes that can be transferred to other members of the microbiota, including opportunistic and pathogenic bacteria.

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. Antibiotics 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 2900 CHF (Swiss Francs).

Riemerella anatipestifer (R. anatipestifer) is one of the common pathogens found in poultry flocks, resulting in serious economic losses for the poultry industry due to high mortality, reduced growth rate, poor feed conversion, increased condemnations, and high treatment costs. The aim of this study was to phenotypically characterize phylogenetic relationships and assess the presence of resistance gene strains of R. anatipestifer obtained from various poultry species in Poland. A total of 57 isolates of Riemerella were included in this study. A polymerase chain reaction (PCR) and matrix assisted laser desorption ionization mass spectrometry (MALDI-TOF MS) were used for identification of the strains. The phylogenetic relationship of the R. anatipestifer isolates was determined by analysing the rpoB gene sequence. The susceptibility to antibiotics was evaluated by minimum inhibitory concentration (MIC) in liquid media. All of the field strains of R. anatipestifer were grouped into one of two clades resulting from rpoB gene sequencing. High MIC50 and MIC90 values were obtained for gentamycin, amikacin, and colistin. Low MIC50 and MIC90 values were obtained for amoxicillin cefuroxime, cefoperazone, piperacillin, and trimethoprim/sulfamethoxazole. Among the resistance genes, tet(X) and ermF were identified most frequently. This is the first phenotypic characterization of R. anatipestifer strains obtained from poultry flocks in Poland.

Non-typhoidal salmonellosis is a dangerous foodborne disease that causes enormous economic loss and threatens public health worldwide. The consumption of food, especially poultry or poultry products, contaminated with non-typhoidal Salmonella (NTS) is the main cause of human salmonellosis. To date, no research has identified the molecular epidemiological characteristics of NTS strains isolated from breeder chicken farms in different provinces of China. In our study, we investigated the antimicrobial resistance, phylogenetic relationships, presence of antimicrobial resistance and virulence genes, and plasmids of NTS isolates recovered from breeder chicken farms in five provinces of China between 2020 and 2021 by using a whole-genome sequencing (WGS) approach and phenotypic methods. All sequenced isolates belonged to six serovars with seven sequence types. Nearly half of the isolates (44.87%) showed phenotypic resistance to at least three classes of antimicrobials. Salmonella enterica serotype Kentucky harbored more antimicrobial resistance genes than the others, which was highly consistent with phenotypic resistance. Furthermore, the carried rate of 104 out of 135 detected virulence genes was 100%. Overall, our WGS results highlight the need for the continuous monitoring of, and additional studies on, the antimicrobial resistance of NTS. Full article
