Abstract: | Background Footrot is a world-wide contagious disease in sheep and goats. It is an infection of the epidermis of the interdigital skin,
and the germinal layers of the horn tissue of the feet. The first case of footrot in Swedish sheep was diagnosed in 2004.
Due to difficulties in distinguishing benign footrot from early cases of virulent footrot and because there is no possibility
for virulence testing of strains of Dichelobacter nodosus in Sweden, the diagnosis is based of the presence or absence of clinical signs of footrot in sheep flocks. Ever since the
first diagnosed case the Swedish Animal Health Service has worked intensively to stop the spread of infection and control
the disease at flock level. However, to continue this work effectively it is important to have knowledge about the distribution
of the disease both nationally and regionally. Therefore, the aims of this study were to estimate the prevalence of footrot
in Swedish lambs at abattoirs and to assess the geographical distribution of the disease. |
