Diplotriaena obtusa (Nematoda: Filariidae) infection in first-year Sylvia atricapilla from Poland – molecular evidence

Insectivorous birds are particularly vulnerable to nematodes with heteroxenous life cycles. Although there are many studies on bird filarioids, they mainly focus on economically important or pet bird species, and as a result, the species diversity of these parasites is insufficiently studied. Resear...

Although there are many studies on bird filarioids, they mainly focus on economically important or pet bird species, and as a result, the species diversity of these parasites is insufficiently studied. Research on the genus Diplotriaena and their hosts is neglected, although they are globally occurring and dangerous parasites with low specificity to the final host.
