AI Article Synopsis
- Trichinellosis is a parasitic disease caused by various species of Trichinella, with cases reported in Algeria linked to jackal meat consumption.
- A study conducted between February 2022 and August 2023 involved examining 33 road-killed carnivorous mammals in Algeria for Trichinella spp. infection using necropsies and DNA analysis.
- The study found T. britovi in a domestic dog, marking the first detection of this species in an animal host in Algeria and indicating the role of domestic dogs in spreading the parasite.
Article Abstract
Trichinellosis is a parasitic disease affecting various mammals (including humans), birds, and reptiles, and is widespread across multiple continents except Antarctica. The disease can be caused by several species of the genus Trichinella and there are documented cases of T. britovi globally. In Algeria, human cases of Trichinella have been reported and a study identifying T. britovi linked the infection to the consumption of jackal meat., with no reports of Trichinella spp. in animals. This preliminary study aimed to investigate the presence of Trichinella spp. infection among carnivorous species in Algeria. Between February 2022 and August 2023, 33 road-killed mammals, mainly carnivores were collected from different locations across five departments: El Tarf, Annaba, Constantine, Algiers, and Oued Souf. Comprehensive parasitological necropsies were conducted, and muscle samples from the dorsal and ventral musculature of the forelimb and the diaphragm of each animal were examined using trichinoscopy. DNA was isolated from positive muscle tissue samples and analyzed using multiplex polymerase chain reaction (PCR). Trichinella spp. cysts were detected in one domestic dog (Canis familiaris) from Ain Kerma, El Tarf. Molecular analysis confirmed all cysts as T. britovi. This study presents the first report of the genus T. britovi in an animal host in Algeria, highlighting the role of domestic dogs in maintaining the sylvatic life cycle of T. britovi in the region.

Background: Trichinellosis is a zoonosis, caused by roundworms of the genus Trichinella. Domestic pigs, wild boars, bears, rodents and horses are reservoir animals. We report a case of neck trichinosis presenting as lateral neck swelling.

Introduction: We studied the cellular immune response in a patient infected since 10 months (along with other 51 people) during a trichinellosis outbreak caused by Trichinella spp.
Methods: A 46 years old female resulted serologically positive for trichinellosis. We isolated peripheral blood mononuclear cells (PBMCs) and incubated them with excretory/secretory antigens (ESA) of Trichinella spiralis (T1) or Trichinella pseudospiralis (T4) to produce antigen specific T cell lines and clones, analysed for the phenotype (T helper or cytotoxic cells), for their T4 or T1 antigens specificity and for their cytokine profile (IFNγ, IL-17A, IL-4) by flow cytometry, thymidine incorporation assay and ELISpot.

Trichinellosis is a major foodborne zoonotic disease responsible for 41 human cases, according to the European Union One Health Zoonoses Report. In southern Spain, a quality management system (QMS) was applied to satellite laboratories (SLs) that conduct meat inspections of spp. ensuring excellence practices.

Article Synopsis
- In Germany, Trichinella spp. primarily affect wild animals like wild boar, foxes, and raccoon dogs, with T. spiralis being the most commonly detected species.
- Legal requirements mandate that all hunted wild boars and other at-risk animals be tested for Trichinella if their meat is for human consumption.
- There has been a rising prevalence of Trichinella-positive wild boar in Germany, especially in the northeastern regions bordering Poland, highlighting the need for preventive measures and thorough inspections to manage the spread.
