“…The seroprevalence of Lyme borreliosis in horses varies with geographical areas. In some areas of the north-eastern USA it is about 33-50% (Funk et al, 2016;Magnarelli et al, 2000), 9.8-42.8% in Brazil (Basile et al, 2016), 31-48% in France (Maurizi et al, 2010), 29% in Denmark (Hansen et al, 2010), 26% in Poland (Stefanciková et al, 2008), 24% in Italy (Ebani et al, 2012), 6% in Turkey (Bhide et al, 2008), and 5.5% in Korea (Lee et al, 2016). Older horses are more prone for positive test response than younger ones (Ebani et al, 2012;Funk et al, 2016).…”
