During a survey for other parasitic infections, tongue and limb muscles of wild bobcats (Lynx rufus) were examined microscopically from a sample of 190 Minnesota bobcats. One batch (n = 50) was studied in 2015, yielding no cases of Trichinella when examined only with hematoxylin and eosin (HE) staining of <25 mg of tissue. In a 2024 cohort (n = 140), this method was paired with a compression of ∼5 g of tissue.

Purpose: Trichinellosis affects around 11 million people globally. Treatments for this medical condition are limited by adverse effects and resistance, emphasising the importance of effective and safe therapies. Consequentially, we sought to study colchicine's synergistic effects with atorvastatin or acetazolamide in the treatment of Trichinella spiralis (T.

Background: Intestinal larva invasion is a crucial step of Trichinella spiralis infection. Intestinal infective larvae (IIL) and their excretory/secretory proteins (ESP) interact with gut epithelium, which often results in gut epithelium barrier injuries. Previous studies showed when T.

Background: C-type lectin (CTL) plays an important act in parasite adhesion, host's cell invasion and immune escape. Our previous studies showed that recombinant Trichinella spiralis C-type lectin (rTsCTL) mediated larval invasion of enteral mucosal epithelium. The aim of this study was to investigate protective immunity produced by vaccination with rTsCTL and its effect on gut epithelial barrier function in a mouse model.

During the intestinal stage of Trichinella spiralis (T. spiralis) infection, it can stimulate host's intestinal peristalsis to expulse worms. 5-hydroxytryptamine (5-HT) is a neurotransmitter which can regulate the contraction of intestinal smooth muscle.
