Abstract

In order to assess the occurrence and regional geographical distribution of Angiostrongylus vasorum and Crenosoma vulpis in Germany, faecal samples of 810 dogs with clinical symptoms of respiratory and circulatory disease, bleeding disorder and/or neurological signs were collected from September 2007 to March 2009. The zinc chloride/sodium chloride flotation and Baermann funnel technique were used to examine the samples for presence of lungworm larvae. Infections with lungworms were diagnosed in 105 (13.0%) of the examined dogs. A. vasorum and C. vulpis were found in 60 (7.4%) and 49 (6.0%) faecal samples, respectively. 33 A. vasorum- and 12 C. vulpis-positive dogs were located in Baden-Württemberg, 13 and 12 in North Rhine-Westphalia, 3 and 4 in Bavaria, 1 and 7 in Rhineland-Palatinate, 7 and 4 in Saarland, 1 and 2 in Saxony, respectively. In Brandenburg only 2 dogs with A. vasorum and in Hesse a total of 5 dogs with C. vulpis were detected. In Mecklenburg-Western Pomerania, Lower Saxony and Thuringia only 1 dog with C. vulpis was detected at a time. 4 dogs were coinfected with A. vasorum and C. vulpis. These surprisingly high prevalence rates indicate that both parasites are endemic in Germany.
