Bovine Besnoitiosis: An emerging disease in Europe

on the Wiley Online Library



The European Food Safety Authority (EFSA) asked the Panel on Animal Health and Welfare to deliver a scientific statement on bovine besnoitiosis. Recent epidemiological data confirm an increased number of cases and geographic expansion of besnoitiosis in cattle herds in some EU MS therefore bovine besnoitiosis should be considered an emerging disease in the EU. However many aspects of the epidemiology of bovine besnoitiosis remain uncertain including prevalence and incidence of infection and disease in endemic areas, routes of transmission and risk-factors associated to infection and disease. The infection caused by the cyst-forming apicomplexan parasite Besnoitia besnoiti can cause serious adverse effects both during the acute and chronic phases of disease. The Panel has highlighted the importance to raise awareness about this disease in particular with farmers and veterinarians regarding clinical signs and the known transmission routes. Epidemiological investigations in endemic areas in Europe are necessary to elucidate the importance of infected animals and the routes of transmission. Diagnostic tools need to be further developed and standardized to address unanswered questions related to the epidemiology and clinical progression of the disease. Appropriate measures and strategies to control of besnoitiosis need to be investigated using the available epidemiological information.
