Background Trichinellosis is a parasitic infection caused by nematodes of the genus , and its principal mode of transmission is the consumption of raw or undercooked contaminated meat. Cardiac involvement in trichinellosis is unusual, yet it represents the most frequent cause of death. Here, we report a case in which -associated myocarditis simulated a myocardial infarction.

Two prominent physicians, Grancher and Brouardel, were sent by the French Health authorities to study the severe ongoing outbreak of trichinellosis in Emersleben, Germany (1883). They produced a highly accurate description of the outbreak and confirmed that they had never observed such cases in France. Grancher performed two necropsies and very precisely described the histological lesions provoked by the larvae entering and transforming muscular fibers. Read More

Introduction: Toll-like receptors (TLRs) play an important role in fast activation of the immune response to a variety of pathogens, including parasites. In this study, we focused on TLR2, because this receptor is one of the best known and most frequently analysed members of the TLR family. The aim of this study was to assess the effect of on expression of TLR2 during the intestinal stage of infection. Read More

Outbreaks of trichinellosis caused by Trichinella papuae have been reported in South-East Asia. Mebendazole and thiabendazole are the treatments of choice for trichinellosis; however, both drugs result in significant side effects and are less effective for muscle-stage larvae (L1). An alternative therapeutic agent is needed to improve treatment. Read More

Trichinellosis is a zoonotic disease, which represents a significant public health concern in some South American countries, such as Argentina and Chile. Its impact is essentially due to absence of adequate control measures on meat from game animals, as well as the presence of illegal slaughterhouses and the trade of meat products without being tested for this parasite. In Argentina, trichinellosis is an endemic disease. Read More

Albendazole (ABZ), an anthelmintic compound widely used in the treatment of systemic nematode infections, is included in the list of class II drugs based on the Biopharmaceutical Classification System. ABZ has limited effectiveness due to its poor water solubility and consequent low bioavailability. Bioavailability of novel ABZ microcrystals based on hydroxyethylcellulose (S4A) or chitosan (S10A) was studied in male and female mice of two inbred lines, from the murine CBi-IGE model of trichinellosis, differing in susceptibility to this parasitosis (line CBi/L, resistant; line CBi+, susceptible).

Historically, human trichinellosis was caused by Trichinella spiralis and transmitted to humans by consumption of undercooked domestic pork. Today, most cases of trichinellosis are caused by other Trichinella species and transmitted by consumption of raw or undercooked wild game meats. Given the increasing global prevalence of wild animal meat-linked trichinellosis, the objectives of this review are: 1) to describe the life cycle and global distribution of Trichinella worms; 2) to describe the changing epidemiology of trichinellosis; 3) to describe the clinical phases of trichinellosis; 4) to recommend the latest diagnostic tests; and 5) to recommend treatment and prevention strategies.

Effective performance of digestion testing methods for , and their use for the detection of infected animals and the prevention of human trichinellosis require system-wide incorporation of appropriate quality assurance (QA) practices. The recommendations of the International Commission on Trichinellosis (ICT) aim to facilitate reliable test results when laboratories operate within a quality management system (QMS) which includes: 1) a quality manual (or similar documentation of the QMS); 2) a validated test method with identified critical control points; 3) a training program; 4) procedures utilizing proficiency testing and other methods to confirm technical capability of analysts; 5) equipment calibration and maintenance; 6) standard operating procedures, related documentation and reporting; 7) procedures to enable continuous monitoring and improvements; and 8) regular internal and third party audits.

Transmission of to domestic livestock, notably pigs, is limited to certain risk factors including feeding of raw meat-containing waste products or animal carcasses and exposure to infected rodents and wildlife. Prevention of infection in food animals is dependent on eliminating risk of exposure to these potential sources of By implementing conditions of controlled management, pig herds can be considered to pose a negligible risk for , and groups of herds which follow these same conditions can be considered to be a compartment with negligible risk for . Pork from pigs originating from a negligible risk herd or compartment would not require further testing or processing to protect consumers from this parasite. Read More

Being able to identify the species or genotype of is of paramount importance not only for epidemiological studies but to better ascertain the source of outbreaks that still occur worldwide. This has become more critical in recent years given the increase in imported meat products and the relationship that wild animals play in the domestic and sylvatic transmission cycles. In contrast to a time when the genus was considered monospecific, research in recent years has revealed that the genus consists of 9 species and at least 3 additional genotypes which have yet to be named.

Host immunity to parasitic nematodes requires the generation of a robust type 2 cytokine response, characterized by the production of interleukin 13 (IL-13), which drives expulsion. Here, we show that infection with helminths in the intestine also induces an ILC2-driven, IL-13-dependent goblet cell hyperplasia and increased production of mucins (Muc5b and Muc5ac) at distal sites, including the lungs and other mucosal barrier sites. Critically, we show that type 2 priming of lung tissue through increased mucin production inhibits the progression of a subsequent lung migratory helminth infection and limits its transit through the airways.
