Special Issue Information

Dear Colleagues,

Cryptic pathogens in wildlife and livestock pose significant challenges due to their covert nature and the difficulty of detecting them. These hidden pathogens can maintain a low-profile existence within host populations, often without causing noticeable symptoms, thereby enabling them to spread silently and widely. Research on cryptic pathogens is critical in understanding the dynamics of disease transmission across different species barriers. This involves genomic studies to identify pathogen strains and ecological investigations to assess how environmental factors influence their spread. The insights gained could lead to more effective disease-control strategies, reducing the risk of outbreaks in both animal populations and humans. This interdisciplinary approach highlights the complex interplay among pathogen biology, host diversity, and ecosystem health.

For this Special Issue, we invite original research papers and reviews addressing the stealthy and often-overlooked world of cryptic pathogens in wildlife and domestic animals. We welcome studies that explore the molecular and ecological aspects of these pathogens, their interactions with hosts, and their impacts on animal health and disease dynamics. Contributions may include genomic investigations to trace pathogen evolution, ecological research on how environmental changes influence pathogen spread, and innovative diagnostic techniques for their detection. Additionally, we welcome papers discussing the implications of these pathogens for public health and strategies for managing their risks in animal populations.

Francisella tularensis is a vector-borne zoonotic bacterium that causes tularemia, a disease of great importance for animal and public health. Although wild lagomorphs are considered one of the major reservoirs of this bacterium, information about the circulation of F. tularensis in European wild rabbit (Oryctolagus cuniculus) and Iberian hare (Lepus granatensis) populations in Europe is still very limited. In Spain, F. tularensis is present in northern central regions, with recurrent outbreaks occurring annually. However, southern Spain has been neglected in terms of monitoring and research. Thus, the aim of this study was to investigate the occurrence of F. tularensis in wild lagomorphs in the Mediterranean ecosystems of southern Spain through using molecular techniques. Spleen samples from 774 European wild rabbits and 178 Iberian hares were collected on 135 hunting grounds between the 2017/2018 and 2022/2023 hunting seasons. A primer set targeting the 16S rRNA gene was used for the detection of F. tularensis DNA. None of the 952 (0.0%; 95%CI: 0.0–0.4) wild lagomorphs sampled showed presence of F. tularensis DNA. Our finding indicates the absence or very low circulation of the bacterium in wild rabbit and Iberian hare populations in the Mediterranean ecosystems of southern Spain, denoting a limited risk of transmission of this pathogen from wild lagomorphs to other sympatric species, including human beings, in this Iberian region.

Enteric parasites pose significant threats to both human and veterinary health, ranking among the top causes of mortality worldwide. Wild migratory waterfowl, such as ducks, may serve as hosts and vectors for these parasites, facilitating their transmission across ecosystems. This study conducted a molecular screening of enteric parasites in three species of wild ducks of the genus Anas (A. acuta, A. platyrhynchos and A. crecca) from Portugal, targeting Blastocystis sp., Balantioides coli, Cryptosporidium spp., Encephalitozoon spp., and Enterocytozoon bieneusi. Fecal samples from 71 ducks were analyzed using PCR and sequencing techniques. The results revealed a 2.82% occurrence of Blastocystis sp. subtype 7 and Cryptosporidium baileyi, marking the first molecular detection of these pathogens in wild ducks in Portugal. While previous studies have documented these parasites in Anas spp. in other regions, this study contributes novel data specific to the Portuguese context. No evidence of Balantioides coli, Encephalitozoon spp. or Enterocytozoon bieneusi was found. These findings highlight the potential role of migratory ducks as vectors for zoonotic protozoa, emphasizing the need for enhanced surveillance of avian populations to mitigate cross-species transmission risks. Further research is warranted to understand the global public health implications associated with migratory waterfowl. Full article
