Special Issue Information

Dear Colleagues,

Wild ungulates are reservoirs of zoonotic diseases and can be used as strategic sentinel species in terrestrial environments, providing early warning of potential risks to human, animal and environmental health. They have been used as bioindicators of some infectious diseases since they i) are ubiquitous, ii) have been increasing in number and geographical range, iii) have considerably large home ranges, iv) are widely hunted, being a source of food-borne diseases, and v) overlap their habitat and distribution area with livestock and humans, serving as a link between human-influenced settings and natural areas, enhancing disease spillover between the wildlife–livestock–human counterparts.

The pressing challenges of infectious and zoonotic diseases in ungulates (e.g., African swine fever in wild boar across Europe) demand an integrated framework that goes beyond the traditional analytical methods of analysis to include an ecological perspective. Understanding how environmental and socioeconomic factors can affect the epidemiology and dynamics of pathogens at an individual, local and regional level is an important step towards the sustainable control of infectious diseases.

This Special Issue aims to present recent research and reviews on the implications and dynamics of wildlife–human interactions, exploring the role that wild ungulates play in the emergence, maintenance, and dispersal of infectious diseases under the One Health framework in order to stimulate interest, understanding, and exploration of this important subject.

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. 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.

Background: The Gram-negative bacterium Anaplasma phagocytophilum is an intracellular pathogen and an etiological agent of human and animal anaplasmosis. Its natural reservoir comprises free-ranging ungulates, including roe deer (Capreolus capreolus) and red deer (Cervus elaphus). These two species of [...] Read more.
Background: The Gram-negative bacterium Anaplasma phagocytophilum is an intracellular pathogen and an etiological agent of human and animal anaplasmosis. Its natural reservoir comprises free-ranging ungulates, including roe deer (Capreolus capreolus) and red deer (Cervus elaphus). These two species of deer also constitute the largest group of game animals in Poland. The aim of the study was to genotype and perform a phylogenetic analysis of A. phagocytophilum strains from roe deer and red deer. Methods: Samples were subjected to PCR amplification, sequencing, and phylogenetic analysis of strain-specific genetic markers (groEL, ankA). Results: Five haplotypes of the groEL gene from A. phagocytophilum and seven haplotypes of ankA were obtained. The phylogenetic analysis classified the groEL into ecotypes I and II. Sequences of the ankA gene were classified into clusters I, II, and III. Conclusions: Strains of A. phagocytophilum from red deer were in the same ecotype and cluster as strains isolated from humans. Strains of A. phagocytophilum from roe deer represented ecotypes (I, II) and clusters (II, III) that were different from those isolated from red deer, and these strains did not show similarity to bacteria from humans. However, roe deer can harbor nonspecific strains of A. phagocytophilum more characteristic to red deer. It appears that the genetic variants from red deer can be pathogenic to humans, but the significance of the variants from roe deer requires more study. Full article
