“…Our study was in line with previously reported histopathological alternation caused by cestode and nematode species infection that is recorded by Shaikh et al [48]. The present results are consistent with the previously reported studies by Ibrahim et al [49] and Mahdy et al [50] in the intestines of domestic pigeons caused by helminthic infection. We attributed this alternation to the persistent pressure of adult worms and migration of its infective stages in intestine pigeons.…”

T HE present study aimed to detect the intestinal parasitic worms and protozoa and their association with intestinal pathological changes among different breed pigeons at Taif governorate. Two hundred and twelve pigeons from four different breeds (Pakistani, local, French, and Harami) were collected in the period from February to June 2022. Clinical examinations of 96 out of 212 pigeons showed emaciation, dullness, greenish to white in color droppings, and diarrhea. Results have shown a higher helminthic (cestodes and nematodes) prevalence rate in Pakistani breed (54.7%), local (26.4%), French (18.9%), and the least infection was detected in Harami breed (11.3%). Three species of cestodes were identified Raillietina echinobothrida (9.9 %), R. cesticillus (3.8%), and R. tetragona (1.4%). Three species of Nematodes Ascaridia galli, Heterakis gallinarum, and Capillaria spp in percentage (7.5%), (3.8%), and (1.4%), respectively, were also identified. The most common protozoa detected were Cryptosporidium spp. (8.0%), Eimeria spp. (5.2%), and Amoeba spp. (4.2%). In addition, Mixed infections were found in 23(10.8%) of all examined pigeons. Histopathological findings in the intestine associated with helminthic and protozoal infestation were necrosis, desquamation of the lining epithelium in the villus crypt and glands, villi atrophy, and inflammatory cell infiltration, especially eosinophils. In conclusion, our study clearly demonstrated the prevalence of helminths and protozoa in the intestine of the main pigeon breeds in Taif governorate, associated with histopathological alternation. Therefore, future studies are needed to reduce avian parasitic transmission routes to livestock and the human population at Taif governorate.

“…The physical traits of the nematode worms in this study verified that they are all members of the Ascaridiidae family, which is subdivided into the genus Ascaridia , as proposed by Dujardin (1845) the presence of two cephalic alae on opposite sides of the body, a club-shaped esophagus without a posterior bulb, and three globular, trilobed, identically sized lips in the mouth; Two spicules, a precloacal sucker with a chitinous rim, and the quantity and arrangement of caudal papillae are present in males; a pointed tail and thick-shelled eggs are present in females. These results corroborated those reported by Ibrahim et al . (2018a) , Abdel Rahman et al .…”

“…The variation in infection rates of helminth species associated with habitat alteration explain such changes in relation to parasite, host, and environmental features ( Carrera-Játiva & Acosta-Jamett, 2023 ) Molecular diagnostics has emerged as the most sensitive and reliable identifying method.

Summary Ascaridia species are the most common nematodes infecting pigeons. The current study investigated specific identity of nematode parasites collected from domestic pigeons (Columba livia domestica) in Al-Qassim Region, Saudi Arabia. Out of 354 pigeons, 13.3 % were infected with nematode parasites. The morphological structure and genetic relationship of nematode worms were studied using conventional methods (Light and scanning electron microscopes) coupled with the newly introduced molecular method. Microscopical and ultrastructure observations showed that the present nematode worms belong to the genus Ascaridia and have all the characteristic features of Ascaridia columbae. Moreover, Random Amplifier morphometric (RAPD) PCR analysis revealed that the present A. columbae had a close identity of up to 98.3 % to Ascaridia columbae JX624729 for Cox-1 gene regions, and up to 98.3 % to Ascaridia nymphii LC057210, and Ascaridia galli EF180058 for ITS1-5.8s- ITS2 rDNA gene regions. Phylogenetic analysis supported the placement of this Ascaridia species within Ascaridiidae family with close relationships to other nematode species obtained from GenBank. Finally, our study recommends using molecular analysis in helminths identification as the main methodology for correct identification especially in closely related species.

“…Additionally, the recovered Raillietina sp. was relatively similar to R. echinobothrida described by Ibrahim et al [29], but it differed from R. echinobothrida in that it had a smooth surface with hair-like microvilli as they appeared in the SEM, whereas R. echinobothrida had longitudinal folds. The number of testes in the present Raillietina sp.…”

Purpose Common tapeworms in poultry digestive tracts are called Raillietina species. The objective of the present study was to characterize the morphological and genetic relationships between the cestode parasites that infect domestic pigeons (Columba livia domestica) in Al-Qassim Region, Saudi Arabia. Methods Using optical and scanning electron microscopy, the general morphology and surface characteristics of the collected cestode parasites were examined. Using sequences from the ND1 and 18S rDNA gene areas, molecular analysis was used to confirm the taxonomy of this parasite based on its morphological characteristics. Results demonstrated a high degree of similarity—up to 98.0% and 74.7%, respectively—between the 18S rDNA and ND1 gene regions and other cestode species found in GenBank. Using close ties, phylogenetic research validated the placement of this Raillietina species within Davaineidae. Conclusion Our findings show that domestic pigeons (C. L. domestica) should be taken into consideration as a potential natural reservoir for several cestode parasite species. To shed light on the evolutionary relationships of Davaineidae, additional research should concentrate on analyzing various genes.
