AI Article Synopsis
- Recent research highlights a diverse range of infectious agents in wildlife, particularly in Chilean pudus, which may pose risks to human and animal health.
- The study found that various pathogens were present in blood samples from wild and captive pudus, with specific percentages indicating their occurrence in the population.
- This investigation marks the first identification of certain pathogens in wild ungulates in South America, indicating a need for further study on the potential role of pudus as infection reservoirs and transmission sources.
Article Abstract
Introduction: Recent evidence shows a high diversity of infectious agents in wildlife that represent a threat to human, domestic, and wild animal health. In Chile, wild populations of the most common cervid species, pudu (), have been reported as hosts for novel pathogens such as -like and a novel ecotype of . A better understanding of the epidemiology of this group and other intracellular bacteria that might have cervids as hosts would enlighten their population relevance. This study aimed to determine the occurrence and genetic diversity of spp., hemotropic mycoplasmas, and in pudus from Chile.
Methods: The DNA was extracted from the blood samples of 69 wild free-ranging and 30 captive pudus from Chile. A combination of real-time (nouG gene for and IS1111 element for ) and conventional PCR (16S rRNA for hemotropic spp. and rpoB, gltA, and ITS for spp.) was used for pathogen screening and molecular characterization.
Results: DNA of spp. was detected in 10.1% [95% CI (5.2-18.2%)] samples, hemotropic spp. in 1.7% [95% CI (0.08-10.1%)], and in 1.0% [95% CI (0.05-6.3%)] samples. Two sequenced samples were identified as -like, and one free-ranging pudu was positive for . While one captive and two free-ranging pudus were positive for , one wild pudu was co-positive for and sp., similar to identified in ruminants.
Discussion: To the best of our knowledge, this is the first report of in wild ungulate species, and and spp. in wild ungulate species in South America. Further research will be necessary to evaluate the potential role of pudu as reservoirs of infection and identify the sources for disease transmission among humans and wild and domestic animals.

Human-wildlife conflict is one of the important research topics in biodiversity and conservation. Understanding the status of wildlife resources and its conflict with human could promote the sustainable protection and management of wildlife. Wild boar () is one of the most widely distributed ungulates in the world, with an increasing population and recently rising levels of conflict with human.

Population density is a valuable metric used to manage wildlife populations. In the Russian Far East, managers use the Formozov- Malyushev-Pereleshin (FMP) snow tracking method to estimate densities of ungulates for hunting management. The FMP also informs Amur tiger () conservation since estimates of prey density and biomass help inform conservation interventions.

The composition and function of animal gut microbiota are shaped by various factors, among which diet is one of the major factors. Diet is affected by seasonal shifts and geographical differences, which in turn impact the host's nutritional levels. To adapt to these environmental changes, the gut microbiome often produces matching responses.

Understanding of predator feeding ecology, interactions among co-occurring predator species, and seasonal changes is critical for conservation management given the important role that predators play in shaping their ecosystems, but is lacking for most regions of the world. Dietary studies have demonstrated varying conclusions in the role that resource partitioning plays in the maintenance of predator communities due to complex inter-related factors that may shape prey use. We used DNA metabarcoding on 581 scat samples to determine the dietary composition, similarity, diversity, and niche overlap of eight predator species (Tibetan wolf (Canis lupus), snow leopard (Panthera uncia), Tibetan brown bear (Ursus arctos pruinosus), Eurasian lynx (Lynx lynx), Tibetan fox (Vulpes ferrilata), red fox (V.

Hand-rearing protocols for nondomestic ungulates used for research, zoological parks, and reintroduction to the wild are evaluated on the basis of implementation practicality, gastrointestinal disturbances, survival to weaning, and growth rates compared with those of dam-raised individuals. Although species-specific protocols utilizing milk replacers formulated for nondomestic ungulates have been reported, no such protocols have been published for pronghorn (Antilocapra americana). Five pronghorn fawns were fed Day One 30/40 Black Tail Deer plus Lactobacillus acidophilus probiotics four times per day with Day One Ultra Boost (all products from Fox Valley Animal Nutrition, Inc, Huntley, IL 60142, USA) added at one feeding per day and weighed twice per week for up to the first 16 wk of life.
