Helminth diversity and seasonality of Angiostrongylus cantonensis in hedgehogs from Mallorca.

Article Synopsis
- Sentinel surveillance is essential for tracking pathogen spread, assessing conservation risks, and evaluating threats to humans, particularly in relation to helminth parasites in hedgehogs.
- In a study of 135 hedgehogs in Mallorca, 11 types of helminth parasites were identified, including an 11.5% prevalence of A. cantonensis, highlighting seasonal patterns in infections linked to the abundance of intermediate hosts like snails.
- The research also uncovered high rates of the lungworm Crenosoma striatum and a first-time detection of Moniliformis saudi in this species, emphasizing the need for ongoing studies to assess the impacts of these parasites on wildlife and public health.
Use of stable isotope ratio analysis to investigate the biology and clinical significance of seal parasites.

Stranded seals are often infected with a broad range of parasites, although whether they are the cause of significant morbidity or an incidental finding is usually unclear. In this study we used stable isotope ratio analysis, a method frequently used to investigate food webs, to explore the extent to which common seal parasites feed directly on host tissue and fluids or absorb host-derived metabolites, which in turn may give an indication of their potential impact on the host's health. The trophic discrimination factor ΔN for the nasal mite, , was mostly positive, ranging between −0.

Article Synopsis
- Crenosoma vulpis is a lungworm affecting dogs worldwide, often leading to chronic cough and respiratory issues, but it is frequently misdiagnosed.
- An 11-month-old Miniature Schnauzer presented with severe coughing and breathing difficulties was diagnosed with lungworms through radiological and bronchoscopic exams that identified the worms obstructing the air passages.
- The infection was confirmed using microscopic and molecular techniques, and the dog was treated with fenbendazole, marking the first molecularly confirmed case of this parasite in Slovakia.

Background: The bovine lungworm Dictyocaulus viviparus negatively impacts bovine health and leads to substantial economic losses. Lungworm infections can be difficult to manage due to the unpredictable and severe nature of clinical outbreaks. Despite the widespread use of macrocyclic lactones (MLs) in grazing cattle in the UK, there have been no confirmed reports of resistant lungworms to date, with only one case of anthelmintic-resistant (ML) lungworm confirmed worldwide.

Article Synopsis
- Lungworm infection, caused by nematodes of the genus Dictyocaulus, significantly impacts both small and large ruminants, but there is limited research on its effects in South American camelids.
- This study marks the first reported case of Dictyocaulus filaria infection in vicunas, following the necropsy of two adult vicunas in Cuzco, Peru, which revealed numerous nematodes in their tracheas.
- The nematodes were confirmed through morphological analysis and genetic sequencing, matching previously identified D. filaria sequences from different countries, highlighting the need for further research on verminous pneumonia in domestic and wild South American camelids.
