“…Nishi et al (2000) also observed low frequency, finding 3.5% of A. suum in Minas Gerais and 1.6% in São Paulo. Similarly, S. ransomi low frequency (0.4%, 11.8%) was also evidenced by Roepstorff et al (1998) studied 14,396 pigs of the Nordic countries.…”

“…The main negative effects on animals are reflected in economic losses for producers, such as: reduced feed conversion, reduced fertility, low number of piglets born and weaned, low weight piglets at birth and at weaning, as well as losses relating to viscera of high condemnation rate in slaughterhouses (Bordin 1987, Nansen & Roepstorff 1999, Roepstorff et al 1998). In addition, pigs are considered the main reservoir of Balantidium coli and Entamoeba polecki, which can infect humans, especially farm laborers (Solaymani-Mohammadi & Petri Jr 2006).…”

From 2012 to 2013 were surveyed gastrointestinal parasites from pig farms located in different municpaliyies in the state of Rio de Janeiro. Fecal samples from 790 pigs were collected from the rectum on 88 family farms and 702 farms with industrial production. The samples were subjected to Faust et al., Sheather, Ritchie, Lutz and direct examination faecal techniques. The estimated parasite prevalence was 93.1% in family farms and 59.1% in industrial farms. Balantidium coli, coccidia and Entamoeba sp. were the parasites with the highest frequencies, and the male and female reproductive categories and fatteners pigs the most infected (p<0.05). Trophozoites of B. coli were most evident in stool samples from semi-solid followed by solid and diarrheal consistencies. Strongyles eggs and Trichuris suis have been detected exclusively in family farms. Ascaris suum eggs and Strongyloides ransomi showed low frequency. The high degree of parasitism, especially protozoa, indicates the need to reassess the management of pigs in both types of production.

“…The lack of knowledge of the pig parasite fauna contrasts with that in countries close to The Netherlands, where such studies have been carried out (Germany: Joachim and Daugschies, 2000;Belgium: De Deken et al, 1982;France: Beloeil et al, 2003;Denmark: Roepstor¡ and Jorsal, 1989; the Nordic countries: Roepstor¡ et al, 1998). In Europe, most studies on many aspects of helminths in pigs, such as their epidemiology and the relation to management have been done in Denmark (Roepstor¡ and Jorsal, 1990;Roepstor¡ and Nansen, 1994;Nansen and Roepstor¡, 1999;Roepstor¡ et al, 1998;Carstensen et al, 2002).…”

The prevalence of gastrointestinal parasites in suckling piglets, weaners, fattening pigs and sows was studied from November 2001 to October 2002 on 16 free-range farms (FRF), 11 organic farms (OF) and 9 conventional farms (CF) by means of faecal examinations of composite samples. Each farm was visited four times with a 3-month interval. Infections with coccidia were found on 43.8% of the FRF, 90.9% of the OF and 66.7% of the CF. Sows had the highest prevalence, particularly on FRF (87.5%) and OF (80%). Ascaris suum was present on 50% of the FRF, 72.7% of the OF and 11.1% of the CF, whereas fattening pigs on FRF (42.9%) and OF (54.5%) had the highest prevalence. Oesophagostomum spp. were observed on 25% of the FRF, 27.2% of the OF and 22.2% of the CF. The infection was most prevalent in the sows on all farm types: 37.5% on FRF, 30% on OF and 22.2% on CF. Trichuris suis was found on 37.5% of the FRF, 36.4% of the OF and 11.1% of the CF. Again, this infection was most prevalent in the sows, particularly on the FRF (50%) and OF (30%). No other gastrointestinal parasite species were found and no clinical signs were observed. No seasonal trends could be distinguished. In many cases, when an age group on a farm was positive for a certain parasite, it remained so during the whole study. This indicates that this parasite was really`endemic' on that farm.The results of this study demonstrate that the prevalence of helminth infections of pigs on farms with outdoor facilities is higher than in pigs on conventional farms.

“…Only one study encompassed a wide range of age categories [7] while assessing important risk factors. The variables tested that were significantly associated with A. suum infections were 'age-group', with large fatteners and gilts (young female swine) recorded to have the highest infection intensity [5], 'country', 'weaning age' as late weaning was associated with higher prevalence of infection, and 'water supply', which indicated that drinking facilities located in the lying area was a risk factor.…”

Ascaris lumbricoides and Ascaris suum are widespread parasitic nematodes of humans and pigs respectively. Recent prevalence data suggests that approximately 1.2 billion people are infected. Adult worms exhibit an overdispersed frequency distribution in their hosts and individuals harbouring heavy burdens display associated morbidity. In this review, we describe the parasite, its distribution and measures undertaken to control infection.
