Use of commercial serological tests to detect schistosomiasis in sheep.

Human schistosomiasis is a zoonotic disease, meaning that wild animals or livestock can serve as reservoirs for the disease. This sustains active parasite transmission in regions where extensive treatment initiatives are underway, potentially undermining efforts to combat schistosomiasis. In multi-host and multi-parasite systems, achieving disease elimination necessitates the incorporation of all reservoir hosts.

Traumatic Tension Pneumothorax: A Tale of Two Pathologies.

Pneumothorax resulting from injury is a common phenomenon in both civilian and military trauma. A pneumothorax or simple pneumothorax is defined as air in the pleural space. A tension pneumothorax can evolve from a simple pneumothorax if there is a continued air leak from the lung without mechanism for egress.

Experimental Infections Reveal Acquired Zoonotic Capacity of Human Schistosomiasis Trough Hybridization.

We are currently witnessing the endemization of urogenital schistosomiasis in southern Europe. The incriminated parasite is a hybrid between a human parasite and a livestock parasite. Using an experimental evolutionary protocol, we created hybrid lines from pure strains of both parasite species.

Immunosuppressive Ability of Trichinella spiralis Adults Can Ameliorate Type 2 Inflammation in a Murine Allergy Model.

Background: There is an increase in the global incidence of allergies. The hygiene hypothesis and the old friend hypothesis reveal that helminths are associated with the prevalence of allergic diseases. The therapeutic potential of Trichinella spiralis is recognized; however, the stage at which it exerts its immunomodulatory effect is unclear.

The gut microbiota contributes to changes in the host immune response induced by Trichinella spiralis.

The gut microbiota plays an important role in parasite-host interactions and the induction of immune defense responses. Trichinella spiralis is an important zoonotic parasite that can directly or indirectly interact with the host in the gut. Changes in the gut microbiota following infection with T.

A Trichinella britovi outbreak in the Northern Alps of France: investigation by a local survey network.

We describe a small family outbreak of trichinellosis caused by the consumption of raw ham from a wild boar (Sus scrofa) hunted in the northern Alps of France in February 2022. Out of the six people, aged 3-69 years, who consumed the meat, three were confirmed cases, and three were suspected cases. Eosinophilia detected in four people was the hallmark that drove the diagnosis.

Aptamer-Based Technologies for Parasite Detection.

Centuries of scientific breakthroughs have brought us closer to understanding and managing the spread of parasitic diseases. Despite ongoing technological advancements in the detection, treatment, and control of parasitic illnesses, their effects on animal and human health remain a major concern worldwide. Aptamers are single-stranded oligonucleotides whose unique three-dimensional structures enable them to interact with high specificity and affinity to a wide range of targets.

Lentinan -triggered butyrate-producing bacteria drive the expulsion of the intestinal helminth in mice.

Trichinellosis caused by is a serious zoonosis with a worldwide distribution. Lentinan (LNT) is known to modulate the intestinal environment with noted health benefits, yet the effect of LNT against intestinal helminth is unknown. In our study, we first observed that LNT could trigger worm expulsion by promoting mucus layer functions through alteration of gut microbiota.

Toxocara cati and Toxoplasma gondii in French Birds of Prey.

Parasites have developed many strategies to ensure their development, multiplication, and dissemination, including the use of reservoir hosts that are often nondomesticated species. Despite drastic reductions in their populations, wild birds remain widespread worldwide and could constitute some of these reservoirs. We focused on the identification of wild bird species harboring parasite stages in their muscles.

Helminth Therapy for Immune-Mediated Inflammatory Diseases: Current and Future Perspectives.

Inflammatory bowel disease and allergic asthma, as typical immune-mediated inflammatory diseases (IMIDs), are associated with immune imbalance caused by complex interactions among environmental, genetic and bacterial factors. The changing immune imbalance of IMIDs not only causes serious pathological damages but also increases the difficulty of treatment. Helminths or helminth-derived molecules have been increasingly employed to treat IMIDs due to their immunoregulatory ability.

Characterizing changes in network connectivity following chronic head trauma in special forces military personnel: a combined resting-fMRI and DTI study.

Methods: Fifteen CANSOFs with a history of chronic exposure to sub-concussive head trauma and concussive injuries (1.

The Anti-Inflammatory Immune Response in Early Intestinal Infection Depends on Serine Protease Inhibitor-Mediated Alternative Activation of Macrophages.

is recognized for its ability to regulate host immune responses via excretory/secretory (ES) products. Serine protease inhibitors (serpins) play an important role in ES product-mediated immunoregulatory effects during infection. In this study, the immunoregulatory properties of a serpin derived from (-serpin) were explored in BALB/c mice.

A two-step morphology-PCR strategy for the identification of nematode larvae recovered from muscles after artificial digestion at meat inspection.

To ensure that meat from livestock and game is safe for human consumption, European legislation lays down rules for mandatory testing. Helminth larvae are a category of zoonotic foodborne pathogens that can contaminate meat. Among helminths, the only zoonotic nematode regulated in Europe regarding meat inspection is Trichinella spp.

A common source for a trichinellosis outbreak reported in France and Serbia in 2017.
