Pearsonema plica is a nematode commonly found in wild carnivores and occasionally in domestic dogs, where infections are often overlooked. This cross-sectional study investigated its prevalence in 88 hunting dogs from five districts in Serbia between October 2021 and May 2024. Urine samples were examined via light microscopy, and molecular analyses (PCR and sequencing of the 18S rRNA gene). Presence of P. plica eggs was found in 20.45% of the tested dogs. Phylogenetic analysis clustered the obtained isolates with reference sequences of P. plica. Hunting activity within two months prior to sampling and irregular or infrequent deworming were significantly associated with higher infection rates. Dogs showing urinary symptoms were more likely to test positive. This study provides the first molecularly confirmed data on P. plica infection in hunting dogs in Serbia and indicates that urinary capillariosis in dogs and the need for greater clinical awareness. However, due to the limited sample size and potential sampling bias, the results should be interpreted with caution. Further large-scale and longitudinal studies are needed to better understand the epidemiology and clinical relevance of this infection in domestic dogs. Full article

Pearsonema spp. nematodes infect the urinary bladder of domestic and wild carnivores. The red fox is considered a reservoir of Pearsonema plica, while the prevalence of Pearsonema spp. in domestic carnivores is still poorly known. This study aimed to assess the occurrence of Pearsonema spp. infection in privately owned cats (26) and dogs (83) from central and northern Italy alongside occurrence in red foxes (42) from central Italy. In positive dogs and cats, associated clinical signs were also evaluated. Urine samples were first examined under a stereomicroscope; then, they were centrifuged and microscopically examined after a flotation test. As for foxes, the urinary bladders were opened and urine was collected and processed as above, while collected nematodes were identified at the species level. Among examined animals, 2/26 cats (7.7%), 1/83 dogs (1.2%), and 38/42 foxes (90.5%) scored 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 in 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 and suggest a possible high occurrence of Pearsonema spp. infection in domestic cats of central Italy. Full article
