The European hedgehog is a synanthropic mammal, widely distributed in Europe. This species usually inhabits the edges of deciduous or mixed woods, but it is also very common in private gardens and public parks. Despite its popularity and frequency of contacts both with humans and with wild and domestic animals, few studies have examined the endoparasitic fauna of the hedgehog in Italy. In the present study, endoparasites of naturally deceased hedgehogs (n = 40) from central Italy (Latium and Tuscany regions) were investigated, along with concurrent gross and histopathological lesions. The most prevalent identified endoparasites were Crenosoma striatum (45%), Capillaria erinacei (42.5%) and Brachylaemus erinacei (22.5%), in accordance with previous reports from hedgehogs in southern Italy. In few subjects, Physaloptera clausa, Acanthocephalans and Cystoisospora rastegaeivae coccidia were also identified. The infection by the lungworm C. striatum was found to be significantly associated (p < 0.01) with bronchial hyperplasia and peribronchiolitis upon histopathological examination. Awareness of the most common parasitic infections in the hedgehog and of their effects on the health of these animals is extremely important, especially in wildlife rescue centers, where European hedgehog represents the most frequently hospitalized mammal species.

Canine urinary capillariosis is caused by the nematode Pearsonema plica. P. plica infection is seldomly detected in clinical practice mainly due to diagnostic limitations. This report describes six cases of urinary capillariosis in dogs from Italy. Recurrent cystitis was observed in one dog, whereas another patient was affected by glomerular amyloidosis. In the remaining animals, the infection was considered an incidental finding. Immature eggs of the parasite were observed with urine sediment examination in 3/6 patients. Increased awareness of the potential pathogenic role of P. plica and clinical disease presentation could help identify infected animals.

Data obtained from wildlife rescue centres are a useful means of understanding threats posed to wild animal populations. Aims of the present study were to investigate the causes of admission and outcomes of Long-eared Owls ( Asio otus) hospitalised in rescue centres in Italy. Data were collected from 13 centres form January 2010 to October 2014 using a web form. The following variables were considered: estimated age at admission; date of admission; habitat at finding location; main cause of admission; and outcome. Major causes of admissions were related to human activities, mainly consisting of collision trauma and collection of uninjured fledglings. Despite nocturnal habits of owls and their protection status, according to European Union Directive 2009/147/ CE and to national Italian laws, gunshot wounds were also represented as an admission cause in adult animals. Overall mortality rate was 47.3%. Considering age classes, the majority of adult animals died while the majority of pulli survived and were later released. Both collisions and gunshot wounds contributed to the higher mortality in adult animals. We suggest that anatomopathological and toxicological investigation of dead casualties, along with post release monitoring of rehabilitated owls, would contribute to a better understanding of mortality causes and to the implementation of more successful rehabilitation techniques.

SummaryReports of Pearsonema plica and Eucoleus böhmi infections in wolves (Canis lupus) in Europe are limited and data on associated lesions are lacking. In the present study urinary bladders, nasal turbinates and faecal samples from 8 necropsied wolves were examined for P. plica and E. böhmi infections and associated lesions. P. plica was identifi ed in the bladder of four wolves. At histological examination, follicular chronic cystitis and eosinophilic cystitis were found. E. böhmi nematodes and eggs were identifi ed from the nasal turbinates and rectal faecal samples of three wolves. Worms and eggs were found embedded in the mucosa among the nasal bone laminae. Two wolves were found coinfected by P. plica and E. böhmi. This is the fi rst report of P. plica and E. böhmi infections in wolves from Italy and the fi rst description of pathological lesions associated with P. plica infection in wolves.

Baylisascaris procyonis is a nematode parasite of the raccoon (Procyon lotor), and it can be responsible for a severe form of larva migrans in humans. This parasite has been reported from many countries all over the world, after translocation of its natural host outside its native geographic range, North America. In the period between January and August 2021, 21 raccoons were cage-trapped and euthanized in Tuscany (Central Italy), in the context of a plan aimed at eradicating a reproductive population of this non-native species. All the animals were submitted for necroscopic examination. Adult ascariids were found in the small intestine of seven raccoons (prevalence 33.3%). Parasites have been identified as B. procyonis based on both morphometric and molecular approaches. The aim of the present article is to report the first finding of this zoonotic parasite from Italy, highlighting the sanitary risks linked to the introduction of alien vertebrate species in new areas.
