Summary: This study highlights the highly variable clinical pictures of dogs infected by A. vasorum, with a significant proportion of subclinically infected dogs. Routine copromicroscopic and/or antigenic tests are crucial in enzootic areas to prevent the sudden onset of potentially life-threatening signs in apparently healthy dogs.

Summary: The authors developed a fast and portable loop-mediated isothermal amplification (LAMP) assay to detect the presence of rat lungworm (Angiostrongylus cantonensis) in cerebrospinal fluid samples from dogs on the Australian east coast. This new method outperforms the previous PCR assay and can be used for portable emergency diagnostics in humans, dogs, and wildlife. It can also be used to screen water supplies and potential food sources for the parasite. This study has important implications for improving diagnostic accessibility.

Summary: An epidemiological study conducted in the Macaronesian Archipelago revealed the presence of human, canine, and feline lungworm species in the region. The study confirmed the endemicity of Angiostrongylus cantonensis in Tenerife and highlighted the importance of regular large-scale monitoring on intermediate, paratenic, and definitive hosts to prevent further spread of lungworm-related diseases in humans and animals.

Summary: Angiostrongylus cantonensis, the leading cause of eosinophilic meningitis, is an emerging zoonotic parasite found in only one of the eight islands in the Canary Islands archipelago, indicating a limited distribution possibly due to recent introduction or isolation effect. The presence of this parasite poses risks to humans and other animals, highlighting the importance of implementing control measures to prevent its expansion to other areas.

Summary: In dogs infected with Angiostrongylus vasorum, respiratory distress and bleeding disorders may occur. Proteomic analysis of infected foxes showed increased protein abundance with chronicity of infection and a more appropriate immunopathological response compared to dogs, suggesting greater tolerance and longer evolutionary adaptation in foxes as key wildlife reservoirs.

Summary: The study investigated the genetic diversity of 323 adult A. vasorum nematodes from 64 foxes living in Zurich, Switzerland, revealing 16 mitochondrial haplotypes with 12 present within individual foxes. Urban foxes showed higher haplotype diversity compared to rural areas, with some unique haplotypes in the Zurich nematode population. Interestingly, foxes from London and Zurich shared the same dominant haplotype of A. vasorum, suggesting potential pathogenic differences.

Summary: This study developed a high-throughput screening method for parasitic nematodes using the wMicroTracker system, and validated its effectiveness in testing natural products against Angiostrongylus cantonensis. Screening of extracts from Hawaiian fungi led to the discovery of two previously unknown compounds with anthelmintic properties. The study also highlighted the value of A. cantonensis and Hawaiian fungi in the search for new anthelmintics.

Summary: This study quantitatively assessed the migration of Angiostrongylus vasorum larvae and evaluated sample storage and diagnostic methods. The results showed that early processing of fecal samples is crucial for detecting infected dogs, and ELISA optical density values do not accurately reflect the infection intensity.

Summary: Canine angiostrongylosis is a cardio-pulmonary gastropod-borne helminthic infection caused by the Angiostrongylus vasorum nematode. The disease presents with non-specific signs and the red fox is the main reservoir for dog infections. In Italy, it is well-documented in certain regions but poorly recognized in the northeastern area. Reporting cases is crucial for clinicians to increase awareness and ensure prompt diagnosis of this potentially life-threatening disease.

Summary: This study provides a synthesis of the knowledge on paratenic hosts of Angiostrongylus cantonensis and investigates their role in causing human neuroangiostrongyliasis worldwide. The review identifies various animals as paratenic hosts, including prawns, crabs, fish, frogs, lizards, and snakes. The potential of these hosts to cause neuroangiostrongyliasis depends on consumption frequency, preparation methods, and infection prevalence. Safe food preparation protocols and public education are crucial for preventing human infections.

Summary: Zoonotic toxocariasis is a significant health concern, and Toxocara canis has received more attention in research compared to Toxocara cati. However, the differences in biology and epidemiology between these two species may have implications for disease impact and control. There is a need for more research on T. cati to understand its unique characteristics and role in zoonotic disease.

Summary: This review highlights the spread of Angiostrongylus vasorum and establishment of Angiostrongylus cantonensis in Europe, emphasizing the increasing relevance of these species to veterinary and medical practitioners. Other members of the genus pose potential risks to wildlife and domestic animals, with further research needed on parasite maintenance and disease emergence. Improved surveillance in animals and humans is also essential for risk assessments and management.

Summary: This study investigated the resistance of gastrointestinal nematodes to anthelmintics on multiple farms in North Devon, England in 2016. The results showed that there was resistance to three anthelmintic classes on average, and the prevalence of resistance was higher in 2016 compared to 2013. Haemonchus contortus, a type of nematode, was commonly found on the tested farms and showed resistance or suspected resistance to all tested anthelmintics. These findings highlight the diversity and progression of anthelmintic resistance and the challenges in detecting resistance in mixed-species infections.

Summary: Gastrointestinal nematode (GIN) infections in livestock are common and have negative effects on health and performance. Due to anthelmintic resistance and climate change, alternative approaches to treatment and management are needed. In this study, a new epidemiological model of GIN transmission in a herd of grazing cattle was developed, taking into account host tolerance, parasite burden, immunity, weather-dependent development of parasites, and grass availability. The model showed satisfactory performance and has the potential to explore altered infection dynamics and optimize treatment strategies.

Summary: The dynamics of anti-T. gondii antibodies and seroconversion in naturally infected goats from the last third of pregnancy to 100 days of lactation were evaluated, and their relationship with hematological and dehydration parameters was examined. The results showed that seroconversion occurred in goats of different physiological states and ages, and it was not related to hydration status.

Summary: The high mortality rate caused by parasitic worms on their hosts is a major concern. Current drugs on the market are often toxic with numerous side effects, necessitating the search for new, more potent molecules. Medicinal plants have been found to contain a wide range of novel molecules that can effectively combat different types of helminths. This review provides an overview of the methods, activities, and mechanisms of action of cyclic peptides, specifically cyclotides, for treating helminthic infections.
