Monitoring Pathogens in Free-Living Large Herbivores in a Nature Reserve in the Netherlands.
Abstract: Monitoring and surveillance of pathogens are crucial for safeguarding animal and public health. While passive surveillance is more common for wild and free-living animals, active monitoring improves the detection and characterisation of specific pathogens relevant to animal and public health. In the (OVP) nature reserve in the Netherlands, an active monitoring system for Heck cattle (), Konik horses () and red deer () has been in place since 1997. This study utilised the data generated from the monitoring system to estimate pathogen prevalence and to evaluate the ongoing monitoring efforts. Yearly prevalences were calculated for each observed pathogen, and probability of freedom from infection was assessed for pathogens that were not detected. In cattle, the highest antibody prevalences (>35%-50%) were observed for Bovine herpesvirus 1 (BoHV-1), Bluetongue virus (BTV), Schmallenberg virus (SBV) and , whereas lower (<25%) prevalences were detected for Bovine viral diarrhoea virus (BVDV), , subsp. (), spp. and . Dublin. Similar pathogens were observed in red deer and cattle, but prevalences were generally lower in red deer. In horses, Equine herpesvirus 1 and 4 (EHV-1 and 4), spp., . Dublin and . Typhimurium were detected. Bovine leukaemia virus (BLV), , and serovar Hardjo were not detected in cattle and red deer, nor were Equine infectious anaemia virus (EIAV), Equine influenza virus (EIV) and West Nile virus (WNV) observed in horses. Most of the detected pathogens are endemic in the Netherlands, while non-detected pathogens often have an official disease-free status. This study provides valuable insights into pathogen presence in free-living large herbivores at the OVP nature reserve. The current monitoring system is highly valuable and its effectiveness can be further enhanced through improvements, such as increased sampling efforts and pathogen prioritisation. This knowledge could guide the implementation of similar monitoring strategies in nature reserves across Europe.

Overview
- This study analyzed long-term active monitoring data of pathogens in free-living large herbivores—Heck cattle, Konik horses, and red deer—at a nature reserve in the Netherlands to estimate pathogen prevalence and assess the effectiveness of surveillance efforts for animal and public health.
Background and Objectives
- Pathogen monitoring in wildlife is essential to protect both animal and public health by early detection and characterisation of infectious agents.
- Wild and free-living animals are commonly monitored through passive surveillance, which relies on reporting of clinical cases or dead animals.
- Active monitoring, which involves systematic sampling of apparently healthy animals, leads to better detection and understanding of pathogen prevalence.
- The study focused on a nature reserve in the Netherlands, known as Oostvaardersplassen (OVP), where an active monitoring system has been in place since 1997 for three large herbivore species: Heck cattle, Konik horses, and red deer.
- A key objective was to use accumulated surveillance data to estimate yearly prevalence of different pathogens in these animal populations and to evaluate how well the ongoing monitoring system performs.
Methods
- The dataset originated from systematic, yearly sampling of the three species within the OVP reserve.
- Pathogen presence was determined primarily by detection of specific antibodies and possibly other diagnostic methods.
- Yearly prevalences—the proportion of animals testing positive for each pathogen—were calculated for each species separately.
- For pathogens that were not detected during surveillance, the probability of freedom from infection (i.e., confidence that the population is really free from that pathogen) was statistically estimated.
Key Findings: Pathogen Prevalence in Heck Cattle
- High antibody prevalence (>35%-50%) observed for:
- Bovine herpesvirus 1 (BoHV-1)
- Bluetongue virus (BTV)
- Schmallenberg virus (SBV)
- Brucella spp.
- Lower prevalence (<25%) detected for:
- Bovine viral diarrhoea virus (BVDV)
- Coxiella burnetii (Q-fever agent)
- Mycobacterium avium subsp. paratuberculosis (MAP)
- Leptospira spp.
- Salmonella enterica serovar Dublin
Pathogens in Red Deer
- Many of the same pathogens identified in cattle were also found in red deer, indicating possible cross-species exposure or shared environmental sources.
- However, prevalence rates in red deer were generally lower compared to cattle.
Pathogens in Konik Horses
- Detected pathogens included:
- Equine herpesvirus types 1 and 4 (EHV-1 and EHV-4)
- Leptospira spp.
- Salmonella enterica serovar Dublin
- Salmonella enterica serovar Typhimurium
Pathogens Not Detected in the Study Populations
- In cattle and red deer:
- Bovine leukaemia virus (BLV)
- Brucella abortus
- Leptospira serovar Hardjo
- In horses:
- Equine infectious anaemia virus (EIAV)
- Equine influenza virus (EIV)
- West Nile virus (WNV)
Interpretation and Significance
- Most detected pathogens are known to be endemic in the Netherlands, indicating that free-living herbivores in the reserve are reservoirs or hosts for these infections.
- Non-detected pathogens commonly have an official disease-free status in the region, supporting the accuracy of the monitoring system’s negative findings.
- Active monitoring in this controlled natural environment provides valuable epidemiological information on pathogen circulation among wildlife species.
Recommendations and Future Directions
- The current active monitoring system is highly valuable for ongoing pathogen surveillance and risk assessment in free-living herbivores.
- Enhancements suggested include:
- Increasing sampling efforts (e.g., higher numbers, more frequent sampling)
- Prioritizing pathogens for targeted surveillance based on public or animal health relevance
- Insights from this study can serve as a model to implement or improve similar active pathogen monitoring programs in other European nature reserves.
- Such monitoring supports early detection of emerging diseases and aids in wildlife management and biosecurity planning.
