Pearsonema

摘要

Pearsonema spp. nematodes live in the urinary bladder and sometimes in the ureters and renal pelvis of domestic and wild carnivores, in which they may be responsible for urinary capillariosis. While the red fox is considered a reservoir of Pearsonema plica, the occurrence of Pearsonema spp. infection in domestic carnivores is still poorly known. This study aimed to assess the occurrence of Pearsonema spp. infection in privately owned cats and dogs from central (Tuscany) and northern Italy (Piedmont and Lombardy) alongside its occurrence in a red fox population from central Italy (Tuscany). Among the examined animals, 2/26 cats (7.7%), 1/83 dogs (1.2%), and 38/42 foxes (90.5%) were found positive. Recurrent cystitis, pollakiuria, and hematuria were the main clinical signs in symptomatic dogs and cats. This is the first study on Pearsonema spp. infection of domestic carnivores examining a large number of privately owned pet animals. Obtained results confirm the role of the red fox as a reservoir for P. plica in Europe and suggest a possible high occurrence of Pearsonema spp. infection in domestic cats of central Italy.
