The purpose of this work was to assess the clinical, haematological and biochemical responses of pigs experimentally inoculated with Trichinella spiralis. Groups of three pigs were inoculated per os with 100, 500 and 5000 T. spiralis muscle larvae, two pigs were used as control. Clinical evaluation of disease in pigs included daily examination, rectal temperature measurements and cardiac and re...

BACKGROUND AND AIMS Substance P (SP) release from sensory nerves induces neurogenic inflammation. Neutral endopeptidase (NEP) degrades SP, thereby limiting its proinflammatory effects. Intestinal inflammation following Trichinella spiralis infection markedly downregulates NEP, resulting in diminished SP degradation, with unknown functional consequences. We hypothesised that diminished expressio...

Trichinella spiralis infection in rodents is associated with suppression of ACh release from myenteric plexus that can be mimicked by macrophage-derived cytokines. We verified the presence of a macrophage infiltrate in the intestine during T. spiralis infection and determined the extent to which this cell type is responsible for the neural changes. C57BL/6 mice were infected with 375 T. spirali...

In this study, we hypothesized that the life history traits of Leiothrix spiralis and L. vivipara would be linked to soil factors of the rupestrian grasslands and that rosette size would be influenced by soil moisture. Soil analyses were performed from five populations of L. spiralis and four populations of L. vivipara. In each area, three replicates were employed in 19 areas of occurrence of L...

OBJECTIVE Three commonly used antihelmenthic drugs including Dormectin (0.2 mg/kg), Ivermectin (0.2 mg/kg) and Levamisole (7.5 mg/kg) were examined for their antihelmenthic efficacy against experimental Trichinella spiralis infection in rats. METHODS One hundred and twenty rats were orally infected with 500 T. spiralis larvae. Drugs were tested against adult worms at 4th day, against migratin...

Trichinella spiralis is an intracellular nematode parasite of mammalian skeletal muscle. Infection of the muscle cell leads to the formation of a host-parasite complex that results in profound alterations to the host cell and a re-alignment of muscle-specific gene expression. The role of parasite excretory-secretory (ES) proteins in mediating these effects is currently unknown, largely due to t...

Vaccination as a preventative strategy against Trichinella spiralis infection is an ongoing effort, although no ideal vaccine candidates have been identified until now. Identification of more effective antigens that have a role in essential life stages of the parasite and that may be effective vaccine candidates is therefore of importance. In the present study, we identified a novel aquaporin g...

Although the innate immune function of mast cells in the acute phase of parasitic and bacterial infections is well established, their participation in chronic immune responses to indolent infection remains incompletely understood. In parasitic infection with Trichinella spiralis, the immune response incorporates both lymphocyte and mast cell-dependent effector functions for pathogen eradication...

Faro, Constance J., Roger D. Reidelberger, and Jeffrey M. Palmer. Suppression of food intake is linked to enteric inflammation in nematode-infected rats. Am. J. Physiol. Regulatory Integrative Comp. Physiol. 278: R118– R124, 2000.—Our aim was to investigate the cause-effect relationship between intestinal inflammation induced by infection with enteric stages of Trichinella spiralis and decrease...

Th2 responses seem to play an important role in defence against Trichinella spiralis (Ts). The neutrophil Activating protein of Helicobacter pylori (HP-NAP), that induces IL-12, and IL-23 expression and shifts to Th1 allergen-specific Th2 cells in vitro was used as an anti-Th2 agent in BALB/c mice infected with T. spiralis. The muscle larvae (ML) burden was lower (p < 0.02) in untreated infecte...
