Prevalence of Trichinella spp. antibodies in wild boars (Sus scrofa) and domestic pigs in Korea

Abstract

ABSTRACT:Trichinellosis is a parasitic zoonosis that is of importance to public health; human trichinellosis usually occurs when improperly cooked pork or wild animal meat is consumed. The purpose of this study was to determine the nationwide seroprevalence of Trichinella infection in wild boar and domestic pig populations in Korea. Using ELISA, we detected no seropositivity among the serum samples of 2350 domestic pigs collected in 2013, indicating that the domestic cycles of Trichinella spp. have disappeared from the domestic pig population in Korea. In contrast, approximately 13% of the 434 wild boars hunted in 2013 were seropositive. Furthermore, the seroprevalence of six of the seven provinces was between 6.7% and 18.3%, indicating that Trichinella infection occurred in the wild boar population throughout the country. The results of this study suggest that Trichinella circulates in the wild boar population and could be transmitted from infected wild boars to other wildlife, domestic pigs, and humans in Korea. Therefore, we recommend continued surveillance of Trichinella infection prevalence in wild animals and an appropriate strategy to prevent human infection in Korea.

Seroprevalence of Trichinellosis among Pigs at Slaughter in a Major Abattoir in Makurdi, Benue State, Nigeria

“…Trichinellosis is an important food-borne parasitic zoonosis that is widely distributed throughout the world (Kim et al, 2015). This study to the best of our knowledge is the first to serologically detect specific antibodies of Trichinella spp amongst Pigs at slaughter in Makurdi, Benue State Nigeria.…”

“…However, horses, dogs and many other animals have also served as sources of infection but humans, swine and horses represent the most important hosts from a medical and veterinary point of view (Murrell and Pozio, 2011;Bruschi, 2012). Transmission from wild animals to domestic animals can occur when there is improper segregation of domestic animals and wildlife (Kim et al, 2015). The domestic cycle includes domestic pigs which may become infected by the consumption of infected rodents, and also through carnivorism and cannibalism (Karn et al, 2008).…”

Seroprevalance of Trichinella spp. in wild boars (Sus scrofa) from Bihor county, western Romania

“…Indirect ELISA is commonly used for the surveillance of Trichinella spp. infection ( Elbers et al, 2000 ; Gamble et al, 2004 ; Kim et al, 2015 ) and it can detect infection levels as low as 1 larvae/ 100g of tissue ( Gamble et al, 1983 ). Møller et al (2005) , by using indirect ELISA, detected Trichinella specific antibodies in sera and muscle fluid samples from wild boars.…”

Serum prevalence to non-viral pathogens in wild felids of Southern Primorye, Russia

“…But the mortality of mammals has not been described in the wild. Among mammals, the «traditional» hosts for this pathogen are wild boars (Kim et al, 2015), bears (Naidenko et al, 2013) and other Carnivores (Gottstein et al, 2009). In Southern Primorye large cats had a higher prevalence to this pathogen than smaller ones, which may be related to their diet.…”

“…This nematode may live and parasitise on almost all mammalian species (and on some avian species as well). But most commonly this para-site infects wild boars (Sus scrofa Linnaeus, 1758) (Kim et al, 2015), bears (Naidenko et al, 2013) and other carnivorous species (Gottstein et al, 2009). Mycoplasma sp.…”
