“…The result of Eimeria spp. infection is similar to [33] in Poland (58.5%), and [34] in Japan (40%) and highly differ from [35] in Ghana and [36] in China. The present result of Balantidium coli infection is differ from [21] in Korea (64.7%), [3] in Kenya (64%) and [37] in Danish (>57%).…”

“…This severely impacts small-scale farmers in developing countries. Coprological examinations suggest that the percentages of pigs infected with T. suis is 25% in Japan (29), 32% in Kenya (31), 38% in Netherlands (11), and 17% in Uganda (32). Upon an animal's ingestion of infective T. suis eggs, the larvae penetrate the cecal and colonic mucosa in the pig intestine, where all subsequent stages of larval development take place.…”

ABSTRACTHelminth parasites ensure their survival by regulating host immunity through mechanisms that dampen inflammation. These properties have recently been exploited therapeutically to treat human diseases. The biocomplexity of the intestinal lumen suggests that interactions between the parasite and the intestinal microbiota would also influence inflammation. In this study, we characterized the microbiota in the porcine proximal colon in response toTrichuris suis(whipworm) infection using 16S rRNA gene-based and whole-genome shotgun (WGS) sequencing. A 21-dayT. suisinfection in four pigs induced a significant change in the composition of the proximal colon microbiota compared to that of three parasite-naive pigs. Among the 15 phyla identified, the abundances ofProteobacteriaandDeferribactereswere changed in infected pigs. The abundances of approximately 13% of genera were significantly altered by infection. Changes in relative abundances ofSuccinivibrioandMucispirillum, for example, may relate to alterations in carbohydrate metabolism and niche disruptions in mucosal interfaces induced by parasitic infection, respectively. Of note, infection byT. suisled to a significant shift in the metabolic potential of the proximal colon microbiota, where 26% of all metabolic pathways identified were affected. Besides carbohydrate metabolism, lysine biosynthesis was repressed as well. A metabolomic analysis of volatile organic compounds (VOCs) in the luminal contents showed a relative absence in infected pigs of cofactors for carbohydrate and lysine biosynthesis, as well as an accumulation of oleic acid, suggesting altered fatty acid absorption contributing to local inflammation. Our findings should facilitate development of strategies for parasitic control in pigs and humans.

“…Humans with liver and lung lesions as well as cases and epidemics of eosinophilic pneumonia have been reported, and A. suum -specific antibodies were present in all cases [11-13]. In Japan and Turkey, 14.7% and 3.7% of pigs, respectively, were estimated to be infected with A. suum [7,14]. The prevalence of A. suum infection in the present study was 17.6%, which was lower than that in a previous report in Korea by Jang [2].…”

“…Matsubayashi et al [14] recently reported that the prevalence of parasite infections in cattle were 76.5% for Eimeria spp., 7.0% for Capillaria bovis , and 3.8% for Trichuris spp. The prevalence of cryptosporidiosis in Korea was 8.9-98.2% in cattle and 9.9-47.7% in pigs [15].…”

The present study was performed to investigate the infection status of intestinal parasites in pigs and beef cattle in rural areas of Chungcheongnam-do, Korea. From November 2009 to April 2010, a total of 241 fecal samples of pigs and beef cattle (136 and 105, respectively) were examined by direct smear and centrifugal sedimentation methods. The overall positive rates of intestinal parasites among pigs and beef cattle were 73.5% and 4.8%, respectively, and the double-infection rate was 10.3% in pigs. Of 136 specimens from pigs, Balantidium coli, Ascaris suum, and Entamoeba spp. infections were found in 88 (64.7%), 24 (17.6%), and 5 cases (3.7%), respectively. Of 105 beef cattle, Entamoeba spp. infections were detected in 5 cases (4.8%). From these results, it is shown that pigs raised on rural farms in Chungcheongnam-do had a high B. coli infection rate and a moderate A. suum infection rate. These results demonstrate that environmentally resistant cysts or eggs could be widespread on the farms examined, and thus an effective hygienic management system is needed to prevent them from serving as the source of infection for human beings.
