“…Also in German investigation (Epe et al, 1997) wild boars under 1-year-old and males tended to be more infected, and in Spain (de-la-Muela et al, 2001) the intensity of infection was greater in juveniles, although the prevalence tended to increase with age. Statistically however, the differences were not confirmed, which is consistent with the results of most other researches (Pence et al, 1988;Barutzki & Richter, 1990;Barutzki et al, 1991;Rajković-Janje et al, 2002;Biddau et al, 2003;Järvis et al, 2007), and also with the present study. In Poland, Tarczyński (1956) found three species of lungworms in wild boars, with the prevalences of 52.…”

“…Later, Epe et al (1997) found M. pudendotectus (93.3 %) and M. elongatus (91.1 %) being predominat in wild boars of German population, followed by M. salmi (80.0 %) and M. confusus (24.5 %), with respectively 28.1, 24.0, 9.8 and 4.3 parasite species specimens. M. pudendotectus (prevalence of 78 %, 58.5 (Järvis et al, 2007), the composition of the species being partly different from that observed on the mainland of Estonia (92, 30 and 89 %, respectively). In southern Europe, in Sardinia island, four of the five lungworm species recorded in Italy were identified, and the highest prevalence were found again for M. salmi (81.8 %) and M. pudendotectus (80 %), whereas M. elongatus infected only 50.9 % animals, and M. confusus 46.4 % (Biddau et al, 2003).…”

“…infects 85 -92 % of wild boars, though Houszka (2001) claims that depending on habitat and nourishment conditions, the prevalence of infection could attain 100 % in humid woodlands, while in dry areas does not exceed 30 %. Natural peculiarities of the area, including sufficient availability of earthworms as the intermediate hosts of Metastrongylidae, are important factors affecting the infection of wild boars (Järvis et al, 2007). There is, however, a dis- Humbert and Henry (1989) reveal that the intensity of lungworm infection depends highly on frequenting the areas at high risk for acquiring the infection, such as the feeding centers, since no parasited earthworms the authors could find in the forest.…”

“…The structure of Metastrongylidae is changing also with years, and the species diversity seem to increase. Järvis et al (2007) state that wild boars from different regions of Europe have quite similar helminthofana, but the species diversity together with infection level is increasing from north to south. Growing host population densities are of essential consequence in structuring parasite communities (Pence et al, 1988, Fernandez-de-Mera et al, 2003, but their structure can also change with introductions.…”

SummaryOf 25 wild boars (Sus scrofa) collected in southern Poland during the winter season of 2009/2010 and examined for lung nematodes, 20 (80.0 %) were concominantly infected, and the mean ± SD intensity reached 84.8 ± 67.6 (range 7 -250) parasites. From the whole of 1695 gathered Metastrongylidae specimens, 1121 (66.1 %) were distinguished to five species: Metastrongylus pudendotectus, M. salmi, M. asymmetricus, M. elongatus and M. confusus. The species ratios were 3.4:2.7:1.5:1.1:1.0, respectively, with the average male to female worms proportion of 1:2.7. M. pudendotectus and M. confusus affected most (76.0 %) of animals, followed by M. salmi (72.0 %), M. elongatus (64.0 %) and M. asymmetricus (40.0 %). Compared to juveniles under 1 year and females, adults and male hosts tended to be more infected, and wild boars inhabiting primeval forest were more affected by lung nematodes than those living in the arable land, all the differences being however not significant. Possible factors structuring Metastrongylidae communities are discussed.

“…Studies on the gastrointestinal helminth fauna of wild Sus scrofa scrofa have been carried out in several European countries (HUMBERT;HENRY, 1989;DE-LA-MUELA et al, 2001;RAJKOVIĆ-JANJE et al, 2002;FERNANDEZ-DE-MERA et al, 2003;JÄRVIS et al, 2007;SENLIK et al, 2011), in Asia (ESLAMI;FARSAD-HAMDI, 1992;SATO et al, 2008) and in North America (SHENDER et al, 2002). However there are only a few studies relating to identification of gastrointestinal parasites in wild boars from commercial farms, and these were conducted in Poland (POPIOŁEK et al, 2010) and in southeastern Brazil (MUNDIM et al, 2004;GOMES et al, 2005).…”

This study aimed to identify the parasites that inhabit the digestive system of Sus scrofa scrofa from a commercial breeding facility in southern Brazil, and reports the first occurrence of Trichostrongylus colubriformis in wild boars. The gastrointestinal tracts of 40 wild boars from a commercial breeding facility were collected and individualized during slaughter in a cold-storage slaughterhouse. Out of this total, 87.5% were parasitized by the helminths Ascaris suum, Trichostrongylus colubriformis, Oesophagostomum dentatum and Trichuris suis. T. colubriformis presented a prevalence of 45%, mean intensity of 28.4 and mean abundance of 12.8. The data from this study showed that T. colubriformis not only has a capacity to develop in the small intestines of wild boars, but also adapts well to animals raised in captivity, thus representing a possible cause of economic loss in commercial wild boar farming.Keywords: Wild boar, Sus scrofa scrofa, helminths, Trichostrongylus colubriformis. gastrointestinal tract. ResumoO estudo teve por objetivo identificar os parasitos que habitam o sistema digestório de Sus scrofa scrofa provenientes de criatório comercial do sul do Brasil, reportando a primeira ocorrência de Trichostrongylus colubriformis em javalis. Foram coletados e individualizados os tratos gastrintestinais de 40 javalis oriundos de criatório comercial durante abate em frigorífico. Destes, 87,5% estavam parasitados por helmintos, sendo eles, Ascaris suum, Trichostrongylus colubriformis, Oesophagostomum dentatum e Trichuris suis. T. colubriformis apresentou prevalência de 45%, intensidade média de 28,4 e abundância média de 12,8. Os dados deste trabalho demonstram que T. colubriformis além da capacidade de desenvolvimento no intestino delgado de javalis, adapta-se bem às criações, representando uma possível causa de perdas econômicas nas criações de javalis.

This study aimed to identify the species of helminths infecting the respiratory tract of Sus scrofa scrofa from commercial breeding and check the existence of a possible antagonistic relationship of these species with Ascaris suum. Forty wild boars were analyzed, and the genus Metastrongylus was recorded in the bronchi and bronchioles of 60 % of these, with the occurrence of the species Metastrongylus apri, Metastrongylus salmi, and Metastrongylus pudendotectus. The highest prevalence found was in M. apri (52.5 %), followed by M. salmi (20 %), and M. pudendotectus (7.5 %), registering the highest prevalence of Metastrongylus in wild boars from commercial breeding so far. M. apri was first reported parasitizing wild boars bred in captivity. There was no observed significant influence of A. suum in the mean intensity of Metastrongylus.
