- Epidemiology and treatment of respiratory nematode infections in western European hedgehogs (Erinaceus europaeus)Publication . Baptista, Catarina Jota; Gama, Inês; Serena, Julia; Heneberg, Petr; Cásero, María; Carvalho, Luís Madeira deRespiratory nematodes are common in rescued western European hedgehogs (Erinaceus europaeus), but their epidemiology and treatment in rehabilitation settings remain poorly defined. We investigated respiratory nematode infections in 78 fecal samples of 30 hedgehogs admitted to a wildlife rehabilitation center in southern Portugal and in putative gastropod intermediate hosts. Outcomes after subcutaneous levamisole (10–20 mg/kg) and ivermectin (3 mg/kg) treatments, monitored by the Baermann technique, were compared. Respiratory nematode infections were highly prevalent in rescued hedgehogs and may be sustained within rehabilitation facilities by infected gastropod intermediate hosts. At the animal level, Crenosoma striatum was detected in 63% of hedgehogs and Capillaria spp. in 7% of hedgehogs, including a mixed infection in one hedgehog. The Baermann technique was the most sensitive method for detecting C. striatum. Samples from outdoor enclosures were more often positive for C. striatum than those from indoor enclosures (55% vs. 29%). All the examined gastropods (10/10) were positive for C. striatum larvae, supporting active transmission within the rehabilitation center. Outcomes were better with levamisole than with ivermectin, although persistence and relapses were frequent. Neither treatment resulted in consistent clearance. These findings support the need for integrated parasite management and standardized treatment protocols in wildlife rehabilitation centers.
- Outbreak of an infectious enteritis in western European hedgehogs (Erinaceus europaeus) in a rescue centrePublication . Cásero, María; Serena, Julia; Gomes-Gonçalves, Sara; Mesquita, João R.; Seixas, Fernanda; Coelho, Ana Cláudia; Baptista, Catarina JotaThe western-European hedgehog (Erinaceus europaeus) is a near-threatened mammal frequently admitted to wildlife rescue centres. In early 2025, an outbreak of haemorrhagic enteritis affected 28 hoglets and juvenile hedgehogs at the Ria Formosa Wildlife Recovery and Research Centre (RIAS) in Portugal, resulting in a mortality rate exceeding 35%. Clinical signs included appetite and weight loss, and diarrhoea (including bloody diarrhoea). Diagnostic testing (parasitology, virology, bacteriology and histopathology) was conducted and Salmonella enterica subsp. enterica, was isolated from internal organs (liver, spleen, intestine, and lung) of four necropsied individuals. Following antimicrobial susceptibility testing, treatment with trimethoprim-sulfamethoxazole associated with critical care led to clinical improvement in surviving animals. This case underscores the challenges in diagnosing and managing infectious disease outbreaks in wildlife rescue centres and highlights the zoonotic risk of diseases that can affect hedgehogs, as salmonellosis. The findings emphasise the need for enhanced surveillance, rapid diagnostics, and effective biosecurity protocols in conservation centres to ensure animal welfare, good recovery rates and mitigate public health risks.
