“…eggs. A prevalence of this trematode ranging from 1 to 6% has been reported in other countries (Boes et al 2000;Capucchio et al 2009). Fasciolosis is highly endemic in cattle in Busia District, with one study reporting a prevalence of 22% (Karanja 2005) and thus free ranging pigs could also be exposed to the infection.…”

Nematode infections are a serious constraint to pig production, especially where free range pig keeping is practiced. This study investigated the epidemiology of nematodes in free range pigs in Busia District, Kenya. Three hundred and six pigs from 135 farms were sampled for faeces that were analysed for nematode eggs per gram (EPG) of faeces using the McMaster technique. The nematode eggs were also identified to genus and species based on morphology. A questionnaire on risk factors was also administered to the pig owners. The overall prevalence and mean nematode EPG were 84.2% and 2,355, respectively. The nematode eggs were identified as those belonging to Oesophagostomum spp. (75%), Strongyloides ransomi (37%), Ascaris suum (18%), Metastrongylus spp. (11%), Trichuris suis (7%) and Physocephalus sexalatus (3%). The prevalence of nematodes was positively correlated (p < 0.05) with the amount of rainfall in the division of the pigs' origin (all nematodes except S. ransomi). The prevalence of nematodes was also associated with the age of the pigs. A lower burden of nematodes was associated (p < 0.05) with a history of deworming (A. suum) and the provision of night housing (S. ransomi and Metastrongylus spp.). In conclusion, this study has provided information on nematode infections and the associated risk factors for free range pigs in Busia District, which can be used when implementing integrated control measures.

“…A higher number of parasites have a direct relationship with the degree of liver fibrosis in cattle (n = 10) [ 13 ]. In 3021 pigs, fascioliasis causes serious hepatic lesions mainly characterized by severe fibrosis [ 14 ]. In addition, periportal fibrosis and collagen deposition around the bile ducts has been also reported in cattle [ 15 , 16 ].…”

BackgroundFascioliasis has been sporadically associated with chronic liver disease on previous studies. In order to describe the current evidence, we carried out a systematic review to assess the association between fascioliasis with liver fibrosis, cirrhosis and cancer.Methodology and Principal FindingsA systematic search of electronic databases (PubMed, LILACS, Scopus, Embase, Cochrane, and Scielo) was conducted from June to July 2015 and yielded 1,557 published studies. Among 21 studies that met inclusion and exclusion criteria, 12 studies explored the association of F. hepatica with liver fibrosis, 4 with liver cirrhosis, and 5 with cancer. Globally these studies suggested the ability of F. hepatica to promote liver fibrosis and cirrhosis. The role of F. hepatica in cancer is unknown. Given the heterogeneity of the studies, a meta-analysis could not be performed.ConclusionsFuture high-quality studies are needed to determine the role of F. hepatica on the development of liver fibrosis, liver cirrhosis, and cancer in humans.

“…However, in natural infections in pigs in Germany, adult flukes have been observed in the bile ducts of pigs (Dalchow and others 1971). In the most recent European study, F hepatica was found in 2·6 per cent of feral Nebrodi black pigs in Messina, Sicily (Capucchio and others 2009). Of 3021 livers examined, six were regarded as having massive infection, with 11 to 18 adult flukes in the bile ducts.…”
