The release of biological control agents has been an important means of controlling invasive species for over 150 years. While these releases have led to the sustainable control of over 250 invasive pest and weed species worldwide, a minority have caused environmental harm. A growing recognition of the risks of biological control led to a focus on risk assessment beginning in the 1990s along with a precipitous decline in releases.

- - The study investigated the presence of antibodies to 13 livestock and zoonotic pathogens in 164 southern pudu deer in Chile from 2011 to 2023, revealing that 20.18% of wild and 30.91% of captive pudus showed exposure to these pathogens.
- - It found that fawn pudus are at a higher risk of infection compared to adults, and those living in free-range conditions are less likely to contract certain parasites.
- - This research marks the first evidence of livestock pathogen exposure in South American wildlife, indicating potential livestock-to-wildlife transmission in Chile’s temperate forests, and linking a past zoo outbreak to abortions among captive pudus.

Introduction: Herpesvirus infections have been highlighted as emerging diseases affecting wildlife health and the conservation of several taxa. Malignant catarrhal fever (MCF) and infectious keratoconjunctivitis (IKC) are two viruses that infect wild ruminants. Nevertheless, epidemiological data on herpesviruses in South American wild ruminants are limited.

- 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.
