Resumo(s)
The 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.
