“…When the female worms reach maturity, they typically excrete eggs containing larval acanthors in feces. The beetle, usually the dung beetle ( Geotrupes stercorarius ), serves as the intermediate host ( 5 ) that ingests the eggs in which the acanthor develops into an acanthella and then a cystacanth. The definitive host is infected orally by uptake of infected beetles or parts of them containing an infectious cystacanth, which will develop into adult male and female Acanthocephalans ( 4 ).…”

Sanitary management and population control of feral pigs remains a major problem in public health, particularly in natural parks where hunting is prohibited and the extensive farming of livestock is common. Macracanthorhynchus hirudinaceus is a zoonotic parasite species with a worldwide distribution of which the natural definitive hosts are primarily pigs and wild boars (Sus scrofa). The present study describes the main anatomo-pathological and parasitological findings in the first case of M. hirudinaceus in feral pigs in the Madonie park in Sicily (Southern Italy). Overall, 52 acanthocephalans were collected from the small intestine of four infected feral pigs. The prevalence among the 36 examined animals was 11.1% with a mean Abundance (mA) and mean Intensity (mI) of 1.4 and 13, respectively. Pathological examination revealed grossly visible nodules on the external surface of the intestines, corresponding to the proboscis of M. hirudinaceus attached deeply into the intestinal wall. In these sites, severe inflammatory reactions in the tissue involved and the destruction of normal intestinal architecture, as well as necrosis and ulceration in the mucosa, submucosa, and part of the muscolaris mucosae were described. This is the first official report of this neglected zoonosis in Italy, in particular in a natural park where the extensive farming of domestic pigs is practiced. This could favor the spread of this parasite in domestic animals and the environment, increasing the accidental risk of infection in human residents of these areas.

“…Macrcantronchyrus Hirudinaceus has an indirect cycle using dung beetles as an intermediate host (Pavlović et al, 2010;Gassó et al, 2016;). It causes serious damage to the intestinal mucosa of their definitive host, through penetrating deep into its gut wall with its proboscis.…”

the body cavity was opened, and the digestive tract removed. The oesophagus, stomach, small and large intestine, and lungs were opened and separately examined for helminths under a microscope (×10, ×40 or ×100 magnification). Results: Thirty three wild boars collected from two areas in the province of El Hajeb, were examined for digestive and respiratory helminth parasites. The overall prevalence of helminths fauna was 100% Helminth species and their prevalence species were Metastrongylus Pedondotectus (85%), followed by Macrcantronchyrus Hirudinaceus (82%), Metastrongylus Confusus (79%) and finally Metastrongylus Salmi (51%). Prevalence and infection intensity were greater in young animals than in older animals. There were no significant differences in prevalence between sexes groups (P>0.05). Prevalence of infection was higher in forest areas compared to cultivate areas. Conclusion: it's the first study made in Morocco about helminth fauna of wild boars, further studies are needed to investigate more the diversity of this parasite fauna.

“…Las 2 primeras especies son parásitos con ciclos indirectos, con hospedadores intermediarios como coleópteros y roedores, respectivamente. Para M. hirudinaceus se sabe que diferentes especies de la familia Scarabaeidae actúan como hospedadores intermediarios (Pavlovic et al, 2010); sin embargo, para Argentina aún es desconocido. Durante la prospección de vísceras de los cerdos salvajes, los autores observaron numerosos coleópteros de la especie Diloboderus abderus o escarabajo torito en el contenido estomacal, además de hallarlos en el ambiente.…”

In Argentina little is known about the parasitofauna in wild pigs. This work discloses parasitic species in a wild population of Sus scrofa in the Bahía Samborombón protected area. Fecal samples were taken from 30 individuals and their viscera were prospected. The total prevalence (P) was 90%, with a specific richness of 11. In the coprological analysis were detected: Eimeria sp. (P = 18.5%), Isospora sp. (P = 22%) (Coccidia), Iodamoeba sp. (P = 52%) (Amoebidae), Macracanthorhynchus hirudinaceus (P = 33%) (Acanthocephala), Ascaris suum (P = 22%), Oesophagostomum dentatum (P = 4%), Globocephalus sp. (P = 7.5%), Metastrongylus sp. (P = 7.5%), Hyostrongylus sp. (P = 18.5%), and Trichuris sp. (P = 4%) (Nematoda). In the helminthological prospections were observed juveniles and adults of M. hirudinaceus (P = 33%) and A. suum (P = 23%); O. dentatum (P = 3%) and hydatid cysts of Echinococcus sp. (P = 20%) (Cestoda, Taeniidae). The association values of the Fager index were not significant except for the pair Isospora sp.-Eimeria sp. The present study shows that the population of wild pigs of Samborombón Bay presents a high richness of parasitic species, many of which have zoonotic importance such as Eimeria sp., Isospora sp., Macracanthorhynchus sp., Ascaris sp., and Echinococcus sp.
