Seven species belonging to the Trichinella genus (five with encapsulated larvae and two with non-encapsulated larvae in host muscles) and three additional genotypes have been described to date: T. spiralis (genotype T1), a cosmopolitan species with a high infectivity to swine and rats; T. nativa (T2), etiological agent of sylvatic trichinellosis in arctic and subarctic areas of the Holarctic re...

Control of Trichinella infection in U.S. pork has traditionally been accomplished by inspection of individual carcasses at slaughter or by post-slaughter processing to inactivate parasites. We propose that an alternative to individual carcass testing or processing can be used when pigs are raised in production systems where risk of exposure to Trichinella spiralis has been mitigated. Declines i...

The erythrocyte antioxidant enzyme levels of catalase, superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) of riboflavin-deficient and Trichinella spiralis-infected rats were investigated. The rats were deprived of riboflavin at the 8th week of the experiment. At that time, the erythrocyte glutathione reductase activity coefficient (EGR AC), as an indicator of riboflavin status, was ...

Mice were infected with 170 Trichinella spiralis larvae, and their blood clearance of carbon particles was studied 4, 7, 13, 32, and 135 days later and compared with that of noninfected control mice. Clearance in mice with a 4-day-old infection was comparable to that in the controls; clearances in mice with 7- and 13-day-old infections were increasingly accelerated and significantly different f...

Trichinellosis is a parasitic disease of humans caused by nematodes from the genus Trichinella, predominantly Trichinella spiralis. If Trichinella infection is suspected based on an epidemiological link and clinical criteria within defined period of time, then finding of Trichinella-specific antibodies in the examined sera provides definitive proof of the establishment of infection. Detection o...

In the present report we study the proteolytic activity of the excretion-secretion and crude extracts of different stages of Trichinella spiralis (Owen, 1835) Railliet, 1895, (muscle-stage larvae, adult worms before and after mating, and newborn larvae) using natural substrates (structural and hematic mammalian proteins). The analysis of the results allow us to set up a certain stage-specificit...

Background Sylvatic Trichinella infection has been found to be very common in Finnish wild carnivores [1], especially locally in Southern and partly Central Finland. Cannibalism and carrion feeding have been regarded as the major source of infection to red foxes and raccoon dogs. Voles have been found the major food items of red foxes [2]. They are regarded as herbivorous, but many herbivores c...

In 2021, the Serbian National Reference Laboratory for Trichinellosis, Institute Application of Nuclear Energy, organized external quality assessment (EQA 2021) detection of Trichinella larvae presence in meat by the magnetic stirrer method (MSM). The aims this study were to examine performance accredited laboratories over time and to compare participants’ performance. EQA 2021 w...
