“…As previously reported, E. garfiai is a non-zoonotic non-pathogenic helminth which can be found in the tongue of wild boars without causing severe lesions. Histopathological results of our study confirmed the presence of eggs and adults in tongue samples associated with mild inflammatory alterations, as previously described [35,38]. Recent findings of E. garfiai in southern Italy have raised interest in collecting more data to better understand the ecology and epidemiology of this particular parasite.…”

“…Recently, the nematode Eucoleus garfiai, synonym Capillaria garfiai, was detected in adult wild boars hunted in southern Italy [35]. Previous studies had already described the presence of E. garfiai in domestic and wild swine in Spain [36], Austria [37], Japan [38], central Italy [39] and Iran [40]. Adults and eggs can be observed in the tongue of wild boars after ingestion of infected earthworms, such as Lumbricus terrestris, Allolobophora caliginosa and Allolobophora rosea, which act as intermediate hosts [41].…”

“…Adults and eggs can be observed in the tongue of wild boars after ingestion of infected earthworms, such as Lumbricus terrestris, Allolobophora caliginosa and Allolobophora rosea, which act as intermediate hosts [41]. Histopathological examination of infected tongues reveals moderate inflammation of the tissue characterized by infiltration of lymphocytes, plasma cells and eosinophils, suggesting reduced pathogenicity of the parasite [38]. Although E. garfiai can be considered a non-zoonotic and slightly pathogenetic parasite, data on the presence of this nematode in wild boars should be increased.…”

Recent reports of Eucoleus garfiai in wild boars in southern Italy have highlighted the need for collecting epidemiological data on the presence of this parasite and understanding the role of possible interactions between wild boars, E. garfiai, and the environment. This study analyses, using histopathological and biomolecular techniques, the presence of E. garfiai in tongue samples of wild boars hunted in four provinces of the Campania and Latium regions (Italy), in areas located above and below 900 m above sea level (asl). Histopathological examinations revealed the presence of adults and eggs of nematodes, which were subsequently identified as E. garfiai by biomolecular analysis, in the tongue epithelium. The detection of the parasite was more frequent in samples collected from hunting areas located above 900 m asl than in those collected from areas located below 900 m asl (66.67% vs. 38.09%; p < 0.01). Some species of earthworms are intermediate hosts of E. garfiai and it is well known that earthworms are more present in high quality soils. Therefore, we can suggest that the higher prevalence of E. garfiai at higher altitudes is probably linked to a greater presence of earthworms in the soil, due to its higher quality in these areas.

Eucoleus garfiai (syn. Capillaria garfiai) is a nematode infecting lingual tissue of domestic and wild swine. Prevalence data for this parasite are scant and often related to accidental findings, occurring only in Japan and a few European countries. In this study, an epidemiological survey was performed in order to identify E. garfiai in wild boar from the Campania region, southern Italy. A total of 153 wild boar carcasses were inspected over the course of two hunting seasons (2019–2020). Histological examinations were performed on tongue samples fixed and stained with haematoxylin and eosin. The scraping of dorsal tongue tissue was carried out to collect adult worms for parasitological examination. Out of 153 wild boars, 40 (26.1%, 95% CI: 19.8–33.6%) tested positive for helminths and/or eggs in tongue tissues. Parasites were identified morphologically and identification was confirmed by molecular analysis of the 18S rRNA gene, showing a 99% nucleotide match with E. garfiai sequences available in literature. No statistically significant differences were found according to age, sex nor hunting province. Our findings agree with previous histopathological data confirming the low pathogenic impact of this nematode. The present study represents the first report of E. garfiai in wild boar from Italy.
