In 2000, two cases of human trichinellosis were detected in the Sierra Grande area of Rio Negro province, Argentina. As part of an investigation of the aetiology of these cases, 300 pigs slaughtered for consumption in the area between 2000 and 2002 were checked for Trichinella infection, by artificial digestion of a muscle sample. Twelve (5.6%) - four (7.3%) of the 55 checked in 2000, five (4.8...

The prevention of human trichinellosis by proper meat inspection is a classic example of successful veterinary public health measures. The microscopic methods which have been used for more than a century to test pigs for trichinae were intended to prevent human disease. However, the value of these relatively insensitive direct detection methods, including trichinoscopy and pooled sample digesti...

Trichinellosis is an important and under-recognized food-borne zoonosis in Southeast Asia. After 30 years of no reports, a small outbreak was described in Central Lao PDR (Laos) in 2003. Here we report a large outbreak of at least 650 estimated patients in Udomxay (northern Laos) in June 2005. Trichinella ELISA assays on serum from 133 patients and Western blot assays on 16 patients were positi...

Clade I nematode species in the genus Trichinella can cause infections in humans that lead to mortality and serious morbidity. There are currently eight recognized species or genotypes that comprise this genus. The species display diverse biological characteristics, the evolutionary significance of which recently has been extensively clarified. Some of that diversity translates into variable im...

Since the XIX century human trichinellosis has remained an unsolved problem of public healthcare in Poland. This paper describes the past situation and analyses current changes in the epidemiological pattern of trichinellosis in Poland. Epidemiological data from the last 60 years, point out that the number of human cases as well as the number of deaths caused by trichinellosis has decreased sig...

Mice challenged intravenously with Listeria monocytogenes at 7 or 21 days after Trichinella spiralis infection demonstrated a higher mean lethal dose and longer survival time than normal mice. This effect of helminthic infection was abrogated after 49 days.

Trichinella spiralis infected rat carcasses were incubated for 6 weeks in several animal feeds to assess how long Trichinella can present a risk for an outbreak in contaminated feeds. In groups of 6, 24 infected target rats were placed in silage, grained barley, propionic acid-preserved feed, and also into simulated pasture conditions. Test environments were sampled after one-, 2-, 4-, and 6-we...

The former 15 EU countries have been spending an estimated 570 million Euro yearly to inspect for Trichinella in pigs primarily raised on industrialized farms with negligible little risk of acquiring the parasite; human trichinellosis in the EU is generally caused by game meat, imported horse meat, or meat from local pigs raised outdoors. Occurrence of both pig and human trichinellosis has sign...
