Nationwide Seroprevalence Survey of Derived Antigens and Specific Antibodies in Dogs from Colombia

is a cardiopulmonary nematode, causing several clinical manifestations in dogs, e.g., severe respiratory signs, coagulopathy, and gastrointestinal or neurological signs. In the last decades, this parasite has been described to spread and emerge in Europe and North America. Scant studies on occurrence in South America exist. Recently, was detected in gastropod intermediate hosts in Colombia, where data on definitive host prevalence, e.g., dogs and wild canids, are still limited. Therefore, the sera of 955 dogs, varying in age and breed from seven different departments all over Colombia, were collected and analysed for antigens and parasite-specific antibodies by ELISA. In total, 1.05 % ( = 10; 95 % CI 0.40-1.69) of the samples were antigen-positive and 2.62 % ( = 25; 95 % CI 1.61-3.63) were antibody-positive. These results confirm the presence of in Colombia, although positive results in antigen and antibody reactions in the same dog were not detected. This study is the first large-scale survey on seroprevalences in dogs from Colombia.
