An international workshop on ParaTB transmission and control

A workshop devoted to discuss the role of wildlife reservoirs of M.a. paratuberculosis was held on 18th August as activity of the 8th International Colloquium on paratuberculosis (Copenhagen, Denmark). This workshop was organized as a dissemination task of the European Project �The Role of Wildlife in the epidemiology of Mycobacterium avium subspecies paratuberculosis in domestic ruminants in Europe� QLK2-CT-2001-00879.

The objectives of the workshop were to present updated information on worldwide prevalence of paratuberculosis infection in wildlife species, and to present the results achieved in the EU project QLK2-CT-2001-00879 about the epidemiology of paratuberculosis in Europe. The workshop was attended by 49 scientists from 20 countries.

The report of the workshop will be included in the Proceedings of the Colloquium.

The agenda was as follows:
1.2.1. M.a. paratuberculosis infection in European wildlife
The first part of the workshop was devoted to the situation of M.a. paratuberculosis infection in European wildlife and the information derived from the EU-funded project QLK2-CT-2001-00879.

ParaTB in wildlife before the EU project. Mike Hutchings. Scottish Agricultural College, Edinburgh, Scotland (UK). This presentation was devoted to a description of the state of the art regarding wildlife and paratuberculosis before this project started.

ParaTB in wildlife in EU countries. Lucía de Juan. Universidad Complutense de Madrid, Spain. Dr. Lucía de Juan, scientific secretary of the Co-ordination Action VENoMYC (, presented the data from paratuberculosis in wildlife in European countries kindly submitted by VENoMYC partners.

Overview of the project. Alastair Greig. Scottish Agricultural College, Edinburgh, Scotland (UK). Co-ordinator of the project, presented the objectives, number of samples analysed, selection of strains for molecular characterization, results and general conclusions of the project QLK2-CT-2001-00879.

Results for the three typing methods for M.a.paratuberculosis. Karen Stevenson. Moredun Research Institute, Edinburgh, Scotland (EU), presented the molecular characterization from domestic and wildlife M.a.paratuberculosis isolates by three different techniques (PFGE, AFLP and IS900-RFLP).

Sensitivity of EU livestock systems to presence of a wildlife host of M.a.paratuberculosis. Dirk Pfeiffer & Javier Guitian. Royal Veterinary College, Hertfordshire, England (UK). This presentation was devoted to epidemiological modelling techniques to compare the efficacies of various paratuberculosis control strategies and to determine the role of wildlife reservoirs in the persistence of paratuberculosis in domestic livestock.

1.2.2. Situation of paratuberculosis in wildlife in other non-European countries. Invited speakers would present data of paratuberculosis in wildlife in different non-European countries.
"Prevalence of Johnes disease (para Tb) in New Zealand wildlife: preliminary surveys and implications for management". Andrea Byrom. Tb epidemiology and management, Manaaki Whenua - Landcare Research Lincoln (New Zealand).

�Presence of M. avium ss. paratuberculosis in North America: ruminants, non-ruminants and their habitats�. Becky Manning. Johne's Testing Center, School of Veterinary Medicine, University of Wisconsin (USA).
