“…While C. boehmi parasitises the upper respiratory tract, i.e. nasal cavities and sinuses [ 41 ], the Capillaria specimens in this study were detected exclusively in the trachea and bronchi. Interestingly, these detected specimens showed a high degree of Cox 1 nucleotide identity (98.5–100%) with a Capillaria specimen from an Australian cat (GenBank acc.…”

“…However, the observed high genetic distance to C. aerophila , comparable to that to C. boehmi , rather implies that the species found here is not C. aerophila . Capillaria boehmi , another capillariid of low host specificity [ 40 ] that occurs in the respiratory tract of carnivores (mainly foxes, mustelids and dogs [ 41 ]), can not only be deferred because of its low nucleotide identity, but furthermore excluded because of its specific localisation in the host [ 40 ].

Cardio-pulmonary parasites of the European wildcat (Felis silvestris) in Germany

Background In the last years, research on feline cardio-pulmonary parasites has considerably increased in Europe. Not only domestic cats (Felis catus), but also European wildcats (Felis silvestris) can serve as definitive hosts for these nematodes. The F. silvestris population in Germany has been growing rapidly within the last decades; therefore, the assessment of its cardio-pulmonary parasite status is of importance to unravel whether the wildcat population serves as a substantial reservoir for these nematodes and might pose a health threat to domestic cats. Methods As part of a nature conservation project for European wildcats in the German federal state Rhineland-Palatinate, lungs (n = 128) and hearts (n = 111) of 128 F. silvestris found dead were examined for cardio-pulmonary parasites. All isolated parasites were identified morphologically, and results were confirmed by molecular analysis of a total of 3–11 specimens of each worm species. Results A total of 70.3% (90/128) wildcats were positive for at least one lungworm species. Angiostrongylus chabaudi was most common (53.1% [68/128]), followed by Aelurostrongylus abstrusus (42.2% [54/128]), Troglostrongylus brevior (31.3% [40/128]) and Capillaria spp. (3.1% [4/128]). Of note, about two-thirds of the infected wildcats harboured coinfections. Infection intensities ranged from 1 to 167 nematodes per wildcat. Generalised linear models revealed a strong correlation between A. chabaudi and A. abstrusus infection, and prevalences were higher in adult than in younger wildcats, except for T. brevior. Moreover, the T. brevior prevalence varied significantly with nutritional status. Conclusions This study shows that feline cardio-pulmonary nematodes are common parasites in European wildcats in Germany but do not appear to have a serious impact on the overall health of the population. Due to presumed spillover events via prey, cardio-pulmonary nematodes may circulate between the wildcat population and domestic cats and might therefore pose a health risk to individual domestic cats.

“…Such diseases occurring in the intestinal tract involve ancylostomiasis, capillariosis, coccidiosis, giardiasis, spirocercosis, tapeworm infection, toxocariosis, trichuriasis and others. They can induce minor to significant pathogenic effects, including severe morbidity and mortality (Kagira & Kanyari, 2000; Morelli et al., 2021; Schantz, 2007).…”

BackgroundThe presence of intestinal parasites influences the growth and well‐being of canids. Additionally, infected dogs and their faeces with considerably higher eggs/oocysts released per gram (epg/opg) of zoonotic parasites contribute to parasitic spillover to humans, domestic animals and sympatric wildlife.ObjectivesThe current study aimed to reveal the prevalence of intestinal parasites (protozoa and helminths) and to list the zoonotically significant parasites in free‐roaming street dogs in Lalitpur Metropolitan City, Nepal.MethodsFresh faecal samples (n = 332) were collected from feral dogs of varying ages and sexes and transported to the research laboratory. The copro microscopic examination was carried out via direct wet mount, formalin ethyl acetate sedimentation, saturated salt flotation, acid‐fast staining and sporulation techniques.ResultsCoproscopy revealed an overall 95.7% (318/332) prevalence rate with 23 diverse species of intestinal parasites (10 protozoa and 13 helminths). Among them, 5 protozoa and 11 helminths possessed zoonotic potential, and their overall prevalence was 92.5%. Helminth's overall prevalence was double that of the protozoa (87.7% vs. 43%). Polyparasitism was dominant over mono parasitism (79.5% vs. 16.3%), and co‐infection of up to seven species of parasites at a time was recorded.ConclusionsUrban street dogs harboured a higher prevalence of intestinal parasites that varied with age and sex. Since most of the reported parasites are zoonotic, dog density and parasitic richness indicate a greater spillover risk to humans and domestic animals. Furthermore, this study also provides appropriate ‘baseline’ data for assessing effective control measures against parasitic infestations among street dogs and controlling their transmission to humans.

“…Due to morphological similarities with other trichuroid eggs, such as those of Trichuris vulpis and Eucoleus boehmi (syn. Capillaria boehmi ), misdiagnosis may occur in infected canids ( Traversa et al, 2010 , 2011 ; Morelli et al, 2021b ). PCR-based methods have been developed to increase diagnostic specificity but are not currently commercially available ( Di Cesare et al., 2012 ).…”
