“…Factors affecting the distribution of gastropod species are important in determining whether the life cycle of G. paralysans can be completed and the potential contact with suitable hosts. Previous studies have indicated that the range of metastrongyloid parasites (i.e., Angiostrongylus vasorum) has expanded into new countries and regions (Traversa et al 2010, Maksimov et al 2017, Lange et al 2018. Models have been used to predict the distribution of A. vasorum and the risk of infection based on climatic variables and their effects on the survival rates of the intermediate hosts (Maksimov et al 2017).…”

Gurltia paralysans (order Strongylida; family Angiostrongylidae) is a metastrongyloid parasite that causes chronic meningomyelitis in domestic cats in South America. The geographic distribution of G. paralysans includes rural and peri-urban areas of Chile and Argentina. However, feline gurltiosis has recently been reported in other South American countries, including Uruguay, Colombia, and Brazil, and was also recently reported in Tenerife, Canary Islands (Spain). Feline gurltiosis is increasingly detected in domestic cats in southern Chile and its apparent geographic range is also increasing, together with an awareness of the disease among veterinarians. The life cycle of the parasite is unknown, but is probably indirect, involving gastropods as the intermediate host, as in other metastrongyloid nematode species. The clinical signs of G. paralysans infection include progressive pelvic limb ataxia, paraparesis, paraplegia, faecal or urinary incontinence, and/or tail paralysis. A definitive diagnosis of feline gurltiosis is still challenging and only possible with necropsy, when adult G. paralysans nematodes are detected within the spinal cord vasculature, together with macroscopic lesions, and characteristic morphological features. A semi-nested PCR method was recently developed for the in vivo diagnosis of this neglected parasite. Current treatment options include macrocyclic lactones and mylbemicn oxime, but the prognosis is poor in severe cases. In this article, we review G. paralysans infection in cats, focusing on the diagnosis shortcomings and the future directions of research into its biology and the associated neurological disease. Comprehensive updates on the epidemiology and clinical features, diagnosis, treatment, and prevention of feline gurltiosis are provided.

Background Several metastrongyloid lungworms are unreported pathogens in Colombia. Angiostrongylus vasorum and Crenosoma vulpis target the cardiopulmonary system of domestic and wild canids. Aelurostrongylus abstrusus and Troglostrongylus brevior infect felids and considering that six wild felid species exist in Colombia, knowledge of feline lungworm infections is important for their conservation. The zoonotic metastrongyloids Angiostrongylus costaricensis and Angiostrongylus cantonensis can cause severe gastrointestinal and neurological diseases. Angiostrongylus costaricensis has been reported in Colombia, while Ang . cantonensis is present in neighbouring countries. Research on the epidemiology of metastrongyloids in Colombia and South America more broadly requires evaluating the role that gastropods play as intermediate hosts in their life cycles. This study assessed the prevalence of metastrongyloid larvae in populations of the invasive giant African snail, Lissachatina fulica , in Colombia. Methodology/Principal findings A total of 609 Lissachantina fulica were collected from 6 Colombian municipalities. The snails were then cryo-euthanized, artificially digested and the sediments examined microscopically for the presence of metastrongyloid larvae. Based on morphological characteristics 53.3% (56/107) of the snails from Puerto Leguízamo (Department of Putumayo) were infected with Ael . abstrusus larvae, 8.4% (9/107) with Ang . vasorum larvae, 6.5% (7/107) with T . brevior larvae and 5.6% (6/107) with C . vulpis larvae, being the region with highest prevalences of the four species. Snails from Andes (Department of Antioquia) and Tulúa (Department of Valle del Cauca) were positive for Ang . vasorum larvae with a prevalence of 4.6 (11/238) and 6.3% (4/64), respectively. Species identifications were confirmed by PCR and sequencing. Conclusions/Significance This epidemiological survey reports for first time the presence of Ael . abstrusus , T . brevior , C . vulpis and Ang . vasorum in L . fulica in a number of regions of Colombia.

“…Frozen gastropods ( P. lamarckii , C. aspersum , T. pisana , R. decollata ) were cut into small pieces and immersed in digestion solution [10 g pepsin powder 2000 FIP-U/g (Robert Kind), 8.5 g NaCl (Carl Roth), 30 mL HCl 37% (Carl Roth), adjusted with distilled water to 1 L] according to Lange et al ( 2018a , b ) and Penagos-Tabares et al ( 2020 ). Briefly, single gastropods were digested for 3 h at 37 °C in sterile 50-mL plastic tubes (Greiner) under constant shaking conditions.…”

Autochthonous Angiostrongylus cantonensis, Angiostrongylus vasorum and Aelurostrongylus abstrusus infections in native terrestrial gastropods from the Macaronesian Archipelago of Spain

et al. 2021

The presence of zoonotic relevant Angiostrongylus cantonensis infections has recently been reported in rat final hosts and gastropod intermediate hosts in Tenerife, Spain. However, data on A. cantonensis, Angiostrongylus vasorum and Aelurostrongylus abstrusus prevalences in endemic gastropods for other islands of the Macaronesian Archipelago are still missing. In order to fill this gap, we conducted an epidemiological study on terrestrial native slug (Plutonia lamarckii) and snail (Cornu aspersum, Theba pisana, Rumina decollata) species in 27 selected locations of Tenerife, Gran Canaria, El Hierro, Lanzarote, La Palma and Fuerteventura. Overall, 131 terrestrial gastropods were collected in winter/spring season 2018/2019 and examined for the presence of metastrongyloid lungworm larvae via artificial digestion. The current data revealed a total prevalence of 4.6% for A. vasorum, 3.8% for A. abstrusus and 0.8% for A. cantonensis. In Tenerife, three lungworm species were detected, thereby re-confirming A. cantonensis endemicity for this island. Prevalences of snails (C. aspersum) originating from El Hierro were 5% for A. abstrusus and 15% for A. vasorum, respectively, with larval burdens up to 290 larvae per specimen. This epidemiological study indicates the presence of human, canine and feline lungworm species in Macaronesia, Spain. The current data—particularly those on anthropozoonotic A. cantonensis—call for a regular large-scale monitoring on intermediate hosts, paratenic hosts and definitive hosts to prevent further spread of lungworm-related diseases in humans and animals.
