Research Project: African Swine Fever Threat Reduction Through Surveillance in the Ukraine, ARS # 693

Location: Arthropod-Borne Animal Diseases Research

Project Number: 5430-32000-003-25
Project Type: Interagency Reimbursable Agreement

Start Date: Jan 15, 2014
End Date: Jan 15, 2015

Objective:
Surveillance and vector The main objective of the project is to design and initiate a system for sustainable surveillance of African swine fever virus (ASFV) in the Ukraine. Sub-objectives include: • Minimize the cost of early ASFV detection by determining the necessary sample size of arthropods and feral swine for accurate detection in a local region. Perform small scale surveillance effort in eastern Ukraine to establish methods for a routine, national program. • Train personnel to perform a routine, national program of ASFV surveillance in Ukraine.

Approach:
This project will strategically and systematically determine the most efficient method of surveillance to mitigate the risk for the emergence and establishment of ASFV in wild pig/soft tick populations. The first step involves a survey of parasitic arthropods (insects and ticks) associated with wild boar and feral pigs and an assessment of their infection status for ASFV. We will then determine which of the soft ticks and other arthropods parasitizing wild boar and feral pigs are competent vectors of ASFV by conducting transmission studies in the laboratory. The predicted distribution of wild boar and feral pigs and the suspect ASFV vectors will be generated using global information systems, spatial analysis, and niche modeling. This predicted distribution will provide a prioritized list of locations for field sampling of wild pigs (animals captured for the purpose and hunted animals) and suspect arthropod vectors. A systematic sampling scheme of priority areas will be conducted to validate the spatial model as a predictive tool that can be used accurately for risk assessment and decision making. This work will be completed by leading Ukrainian specialists in collaboration with USDA investigators. It is expected that the international community will benefit from the evidence-based data generated by this project, which will support ASFV surveillance systems and epizootic risk analysis for ASF control. A. SUMMARY. Year #1 Task 1. Surveillance of ticks in the natural habitat of feral swine in Ukraine. 1.1 Assessing the presence of soft ticks in Ukraine. 1.2. Screening of soft ticks for possible ASF virus presence. Year #2 Task 2. Surveillance of hunted feral swine in the regions adjacent to the ASF affected regions of Russia. 2.1 Assessing tick parasitism of wild boar and feral swine in the Ukraine
