Over 4 years, only two known cases of fluke invasions were diagnosed in racing pigeons ( Columba livia ) originating from different regions of Poland. In both cases, the invasion was characterized by a very high mortality (approximately 70%), and the source of the infestation was snails of the Lymnaeidae family eaten by pigeons. Fluke invasions in pigeons are extremely rare and to date have not been described in Poland. Therefore, the occurrence of the symptoms of hemorrhagic diarrhea and sudden deaths of either adult pigeons or nestlings were suspected to be associated with poisoning. Autopsy revealed an invasion of flukes causing hemorrhagic enteritis. Renal failure and spleen atrophy were also found in the birds. Using molecular biology techniques, infestation with the fluke Echinostoma revolutum was determined in the second case.

“…has been described as a species ''eating'' kidney parenchyma in a pigeon by Hooimeijer and Dorrestein (8). Kidney failure in pigeons may also be caused by other species of Trematoda, such as Paratanaisia bragai described in South America (11,17,20). Fluke eggs are excreted with feces, which offers the opportunity of in vivo diagnosis.…”

“…Since the first description by Santos in 1934 (Giovannoni and Malheiro 1952), Paratanaisia spp. have been described in several avian species (Gomes et al 2005;Tavela et al 2014;Xavier et al 2015;Momo et al 2016, Santi et al 2017. However, most of the reports referred to P. bragai or to undetermined species (Paratanaisia spp.).…”

Renal trematode infection in wild birds: histopathological, morphological, and molecular aspects

et al. 2018

View full text Add to dashboard Cite

Paratanaisia are eucotylidae digeneans that affect the upper urinary tract of birds. This genus contains three species (Paratanaisia bragai, P. robusta, and P. confusa) with similar morphological features. Macroscopic and microscopic damage caused by these parasites ranges from the irrelevant to significant lesions. This study aimed to describe the histological, morphological, and molecular features of the renal tissues and parasite specimens obtained from naturally infected free-ranging and captive wild birds in Brazil. Histopathological evaluations were performed on 103 slides containing kidney tissue sections from parasitized birds. Parasites were observed inside the collecting ducts, causing the dilation and destruction of the lining epithelial cells and alterations in other structures of the renal parenchyma. Such findings indicate that Paratanaisia have pathogenic potential in a wide range of hosts, suggesting low host specificity. The parasites recovered from the kidneys of 10 birds, including Columbiformes, Galliformes, Strigiformes, and Cuculiformes, were morphologically evaluated and identified as Paratanaisia sp. Formalin-fixed paraffin-embedded kidney fragments were subjected to conventional PCR assays targeting the 18S and 28S rDNA genes. A Bayesian inference analysis based on an 800-bp 18S rDNA gene fragment separated the trematode genus accurately, clustering all of the parasites tested with a previously described P. bragai specimen. Analyses on a small fragment of the 28S rDNA gene did not allow for accurately differentiating the Paratanaisia species. Therefore, further morphological studies with additional molecular markers are necessary to improve our understanding of the alpha-taxonomy of this group.

This report presents a description of natural infection of an adult free-living guira cuckoo with Paratanaisia confusa. Histological and morphological evaluations of renal and parasite samples were performed. The morphological analysis of the parasites revealed spiny tegument, characteristic of P. confusa helminthes. Although macroscopic alterations were absent in the kidneys, the histopathology revealed parasites inside the collecting ducts causing dilatation and destruction of the lining epithelial cells in addition to small focal inflammatory infiltrates in the renal parenchyma. However, as the bird was free-living and naturally infected it was not possible to confirm if all these alterations were directly caused by the parasite presence or if they were related to causes other than the parasitism. Nonetheless, such findings indicate that these trematodes may have pathogenic potential in this host.Keywords: Histopathology, Trematoda, Digenea, Eucotylidae, new host record. ResumoA infecção de um anu-branco, de vida livre, por Paratanaisia confusa é descrita. Avaliações histológicas e morfológicas de amostras renais e dos parasitas foram realizadas. A análise morfológica dos parasitas revelou a presença de tegumento espinhoso, que é característico de P. confusa. Embora alterações renais macroscópicas estivessem ausentes, a histopatologia revelou a presença de parasitas no interior de ductos coletores, provocando dilatação destes e destruição das células epiteliais, além de discretos infiltrados inflamatórios focais no parênquima renal. Entretanto, como a ave era proveniente de vida livre e naturalmente infectada, não foi possível confirmar se todas as alterações observadas foram diretamente provocadas pela presença dos parasitas, ou se estavam relacionadas a outras causas. Todavia, esses achados indicam que os trematódeos dessa espécie possam ter potencial patogênico no hospedeiro estudado.Palavras-chave: Histopatologia, Trematoda, Digenea, Eucotylidae, novo registro de hospedeiro.
