To understand the mechanisms of infection and to attempt to simulate human infection by the Anisakidae family, many in vivo experimental approaches have been developed. The aim was to develop and present a technique for the induction of an oral infection through the use of an intra-gastric gavage of live Anisakis simplex in mice. A commercial pediatric gastric tube (No. 4) was cut longitudinally to produce a 3-cm slit at the distal end where the larva was placed to then be administered to the stomach of the mouse. There were no abnormal clinical complications before, during or after the procedure. In conclusion oral infection through the direct delivery of larvae in the stomach is simple and effective.

November 2024
School of Medicine and Biomedical Sciences, Porto University, 4050-313 Porto, Portugal.
Article Synopsis
- This study explores the high prevalence of Anisakid nematodes in blue whiting caught off Portugal, using molecular detection methods like conventional PCR and Sanger sequencing.
- All 50 fish examined were infected, with a breakdown revealing 68.1% of the larvae as one species, marking a first report for another species in these fish, indicating a significant public health risk due to rising raw seafood consumption.
- The findings emphasize the need for better detection methods and safety practices to minimize the risk of anisakidosis, alongside further research on the allergenic potential of these parasites and their environmental distribution.
New Insights on the Diversity, Ecology and Genetic Population Structure of spp. from Fish and Cetacean Hosts from Northeast Atlantic Waters.

Instituto de Investigaciones Marinas, Consejo Superior de Investigaciones Científicas, IIM-CSIC, 36208 Vigo, Spain.
In the last 25 years, nematode parasites of the genus have attracted international attention from various socio-economic sectors, with serious concern about the impact of these parasites on seafood quality and safety, and public health (related to both zoonoses and allergy). A knowledge-based understanding of the population structure of spp. is useful to provide valuable data about the infection dynamics, host specificity and its ability to adapt to local environments and to climate change by adapting to the food-web structure.

Article Synopsis
- The Canary Islands feature a rich diversity of marine species, particularly in stranded cetaceans, which provide valuable scientific insights.
- The study analyzed 233 stranded cetaceans from 2018 to 2022, identifying 18 types of parasites, with adult and juvenile animals being the most affected.
- Accurate identification of these parasites is crucial for understanding disease patterns, evaluating the health of cetacean populations, and crafting conservation strategies.

Anses, Laboratory for Food Safety, Boulogne-sur-Mer, France.
Anisakis simplex larvae, commonly found in marine fish, cause anisakiasis in humans, resulting in gastric to gastro-allergic symptoms. Despite known health risks, the impact of Anisakidae larvae on fish hosts is less understood. This study aimed to investigate this interaction by assessing the feeding strategy of A.

Article Synopsis
- * This study investigates the nematicidal properties of essential oils from two varieties of *L.* (subsp. *SMM* and *SMV*), known for their therapeutic benefits in traditional medicine.
- * In laboratory tests, both essential oils effectively killed anisakis larvae within 24 hours and inhibited acetylcholinesterase activity, suggesting their potential use in medical and food-related applications.
