“…Thus, in Chile, the cougar and the wild boar are the only species that represent any evidence of a possibly existing sylvatic cycle of Trichinella (García, et al, 2005;Hidalgo, et al, 2013). In contrast, in Argentina, Trichinella has been documented in wild boar (Cohen, et al, 2010), and it has also been found in the armadillo (Chaetophractus villosus), the central pericote (Graomys centralis), and in a species of fox (Lycalopex gymnocerus gracilis) (Minoprio, et al, 1967;Krivokapich, et al, 2006). In addition, another species, T. patagoniensis, is also reported circulating among Argentinean cougars (Krivokapich, et al, 2012).…”

SummaryThe genus Trichinella is widespread in all continents but Antarctica. The only way to identify the species/genotypes is through molecular analyses. In Chile, only one study has reported Trichinella larvae in a cougar, but the species of Trichinella was not identifi ed. In this work, the fi nding of Trichinella larvae in a cougar, together with their genotypic identifi cation, is the fi rst documentation of such in Chile. The cougar was found run over by a vehicle in the Biobío Region. Larvae were isolated following artifi cial digestion of the diaphragm and analyzed by means of multiplex polymerase chain reaction (PCR). A PCR product of 173 base pairs allowed for the classifi cation of the larvae as T. spiralis. It is the fi rst record of the species in Chilean wildlife. This fi nding in Chile is interesting in terms of human health, suggesting a possible role of the cougar as a reservoir for this parasite

“…Prevalence estimates depend on the geographical region and the detection methods used: Trichinella antibodies were found in 0.35 % of pigs in the Netherlands (van der Giessen et al 2007), 0.2 % of wild boar muscle samples contained Trichinella in Spain (Boadella et al 2012), a 0.37 % prevalence was estimated in pigs in the northeastern United States (Gamble et al 1999), in China prevalence data ranged from 0.01 to 29.95 % by serological testing to 0-5.75 % in pigs slaughtered at abattoirs, respectively (Cui and Wang 2011), 19.9 % Vietnam pigs tested positive by E/S ELISA (Vu Thi et al 2010), antibody prevalence was 0.0002-0.0003 % in wild boars in France (Pozio et al 1996), a prevalence of 1.3 % was established for wild boars in Finland (Oivanen et al 2002) and of 11.4 % wild boars in Argentina by artificial digestion (Cohen et al 2010). Despite a broad spectrum of hosts, Trichinella spp.…”

Zoonoses - Infections Affecting Humans and Animals

View full text Add to dashboard Cite

Swine and their products have become a central part of food systems around the world. Global pork production has rapidly increased over the past 30 years, leading to the intensification of the swine industry: though there are fewer farms now, those farms that do persist raise ever-larger numbers of animals. This increases the transmission of pathogens both amongst animal herds, and between animals and their human caretakers. Furthermore, increased stress to animals and the potential for amplification of pathogens in the farming environment can lead to a higher burden of disease-causing organisms in and on meat products, which then make their way to consumers world-wide. As such, swine and their meat products have the potential to introduce new zoonotic diseases into populations via multiple routes of transmission. Here we discuss several examples of zoonotic diseases of swine origin, reviewing diseases with bacterial, viral, or parasitic causes. Background and IntroductionPork is rapidly becoming the world's source of protein. Global pork production increased more than 80 % between 198580 % between and 201080 % between (Fournie et al. 2012, and this trend has led to the intensification of swine husbandry, with fewer and fewer facilities present, but each raising larger numbers of individual animals. China has been a driver of this market, accounting for approximately 50 % of total global pig production (Fournie et al. 2012). As swine production has intensified, so has concern over how these modifications in husbandry may affect the transmission of disease amongst pigs as well as to human caretakers. It has been estimated that more than 60 % of emerging diseases are zoonotic (Jones et al. 2008). A recent review (Fournie et al. 2012) identified 77 pathogens that had not been described in swine prior to 1985, including 39 viruses and 32 bacterial species. Not surprisingly, the top 20 % of pork-producing countries accounted for 82 % of these emerging pathogens. Of these 77 novel species found to infect swine, 30 (39 %) are zoonotic, and 23

“…Today in Argentina, there are endemic, nonendemic and Trichinella-free provinces [4]; however, infected animals have been recently discovered in some areas which were considered until now Trichinella-free, such as in the National Park Administration, located in the Centre-east of the Entre Rios province, along the western riverside of the Uruguay River, where 11.4% of tested wild boars were found to be infected with T. spiralis although with a low parasite burden [5]. In the period between 1990 and 2005, a total of 5,221 human cases were reported with an average incidence of 1.48%, caused by domestic pig meat consumption [2].…”

Trichinellosis in developing countries: is it neglected?

Trichinellosis is a foodborne zoonosis caused by the parasitic nematode Trichinella, which is characterized by an extremely wide host range and geographical distribution. The aim of the present review is to provide epidemiological information on animal and human trichinellosis occurring in developing countries in the different continents, where cooking habits along with poverty and poor sanitary conditions and lack of veterinary controls may facilitate the occurrence of human trichinellosis outbreaks.
