Parasitic helminths of pigeons and turkeys are worldwide spread causing mortalities and considerable economic losses. Accordingly, intestinal tracts of domestic pigeons (Columba livia domestica) and domestic turkeys (Meleagris gallopavo) were examined in Beni-Suef province, Egypt to detect their helminth fauna. A total of 740 intestinal samples from pigeons and 100 from turkeys were investigated during the period from June 2015 to May 2016. The overall prevalence of recovered helminths was 11.76% (87/740) in pigeons. The recovered species were identified as two trematodes, 5 cestodes and 4 nematodes. Digeneans were Brachylaima cribbi (1/740; 0.14%) and unidentified Brachylaima sp. (0.14%). Cestodal species were identified as Raillietina echinobothrida (33/740; 4.46%), Raillietina cesticillus (7/740; 0.95%), Raillietina tetragona (7/740; 0.95%), Cotugnia digonopora (5/740; 0.68%) and Hymenolepis carioca (2/740; 0.27%). Among cestodes, R. echinobothrida was the most predominant one. Recovered nematodal species were Ascaridia columbae (22/740; 3%), Subulura brumpti (6/740; 0.81%), Heterakis gallinarum (3/740; 0.41%) and Capillaria spp. (2/740; 0.27%). Ascaridia dissimilis was the only helminth species detected in turkeys (6/100; 6%). The highest prevalence of infection was seen in winter and summer. Tapeworms and round worms were highly prevalent at the summer. The recorded trematodal infection was found in winter. To the best of author's knowledge, adult Brachylaima spp. was first recorded from pigeons in Egypt. Veterinarians and workers of poultry industry must be aware towards the potential role of arthropods as vectors of such helminths among both domestic and wild birds.

“…Since their original description, these digeneans have been recorded parasitizing several bird species, including those belonging to the orders Galliformes (Menezes et al 2001;Gomes et al 2005), Psittaciformes (Luppi et al 2007), Tinamiformes (Mapeli et al 2003;Momo and Werther 2013;Momo et al 2016), Ciconiiformes (Abdo and Sultan 2013), Section Editor: Christoph G. Grevelding Passeriformes (Unwin et al 2013;Tavela et al 2014), Columbiformes (Taroda et al 2013;Unwin et al 2013;Xavier et al 2015), and Cuculiformes (Santi et al 2017), suggesting low host specificity.…”

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.

“…Previously, P. confusa has been described in captive Rhynchotus rufescens (MAPELI et al, 2003;MOMO & WERTHER, 2013) and free-living Zenaida auriculata (TARODA et al, 2013). Therefore, this is the first report of this digenean in Guira guira.…”

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.
