title: First report of Eucoleus boehmi (syn. Capillaria boehmi) in dogs in north-western Italy, with scanning electron microscopy of the eggs.
abstract: Dogs can be infected by several nematodes of the Trichuridae family. Trichuridae eggs are all similar, barrel shaped with polar plugs, and misdiagnosis among different species can occur. The most common species is Trichuris vulpis, while the respiratory parasites Eucoleus boehmi (syn. Capillaria boehmi) and Eucoleus aerophilus (syn. Capillaria aerophila) are rarely observed in pets. E. boehmi is reported for the first time in this study in north-western Italy with other Trichuridae. Dog faecal samples (270) were examined by flotation. E. boehmi (2.2%), E. aerophilus (4.4%) and T. vulpis (12.2%) were found; identification was done with measurements and through observation of morphological characters already known. The specific identification of E. boehmi was confirmed using scanning electron microscopy: its egg shell shows a dense network with a fine mesh, surrounding small pits, on the contrary E. aerophilus eggs present a thick mesh with wide depressions, while T. vulpis eggs surface is smooth.
