title: Canine and feline infections by cardiopulmonary nematodes in central and southern Italy.
abstract: Capillaria aerophila, Aelurostrongylus abstrusus, Angiostrongylus vasorum and Dirofilaria immitis are cardiopulmonary nematodes affecting dogs and cats and presently emerging in several countries. The results obtained in 2009 - 2010 during a study aiming to investigate the occurrence of these nematodes in regions from Central (Marche and Abruzzo regions--Sites A and B, respectively) and southern (Apulia--Site C) Italy are here reported. A total of 534 and 436 individual faecal samples collected from dogs and cats were examined, together with 471 and 34 faecal environmental samples taken from dog shelters and catteries. One hundred and ninety-two individual blood samples were also collected from dogs. Faeces were examined using copromicroscopical flotations and Baermann technique, whereas blood samples were tested by Knott's method. Eggs of C. aerophila were detected in 1.48 % and 20 % (Site A), 8.67 % and 2.71 % (Site B), and 16.67 % and 0 % (Site C) of individual and environmental canine samples. C. aerophila was found in 2.90 % (Site A), 3.03 % (Site B) and 14.29 % (Site C) of individual cats. Larvae of A. vasorum were found in 0.96 % and 2.48 % of individual and environmental samples from Site B, respectively, while those of A. abstrusus in 1.82 % (Site A) and 9.96 % (Site B) of individual faeces. Microfilariae of Dirofilaria immitis, identified on the basis of key morphological and morphometric features, were detected in 2.56 % of samples collected from Site B. Despite the small sample size, these results indicate that cardiopulmonary nematodes occur in Central and southern Italy, thus they should be included in the differential diagnosis of pet cardiorespiratory diseases. Larger surveys are necessary to gain more information on the diffusion of these parasites, especially for C. aerophila and A. vasorum, for which the actual distribution is poorly known.
