Abstract
The European hedgehog (Erinaceus europaeus) is a common wildlife species in European countries. Populations are declining due to anthropogenic factors and natural diseases. Verminous pneumonia has been observed as a frequent infectious disease in hedgehogs submitted for diagnostic postmortem examination. This prompted the present in-depth investigation on the lungs of 27 necropsied hedgehogs with confirmed lungworm infections, with or without antiparasitic treatment prior to death. The histological and/or parasitic (fecal samples) examination identified Capillaria aerophila infection in most animals (82%). The parasites were found free in the airway lumen and/or within the airway epithelium, from the larynx to bronchioles. Embedded worms and eggs were associated with epithelial hyperplasia or metaplasia, and long-term inflammation. More than half of the animals (59%) carried Crenosoma striatum, and 41% had a coinfection. C striatum adults were predominantly found free in the lumen of bronchi and bronchioles, and larvae were occasionally seen in granulomas in the pulmonary interstitium, the liver, and the intestine. Independent of the parasite species, a lymphoplasmacytic peribronchitis and, less frequently, interstitial infiltration of eosinophils, neutrophils, and macrophages as well as pneumocyte type II hyperplasia was seen. Interestingly, the extent of pneumonia was not correlated with age, respiratory clinical signs, antiparasitic treatment, or single or coinfection. Verminous pneumonia appeared to be the cause of death in over 25% of the animals, indicating that these parasites not only coexist with hedgehogs but can also be a primary pathogen in this species.

Abstract
With over 300 terrestrial and aquatic mammalian species, Iran is considered a country with an ample mastofauna. Although many studies have assessed the distribution of gastrointestinal helminth parasites in animals and humans in Iran, lungworms have not received adequate attention. Following a previous article in which we reviewed the diversity and prevalence of lungworm infections in pastoral and wild ruminants of Iran, this report compiles the available scientific information about the occurrence of lungworms in non-ruminant mammals and humans from 1980 to 2022 to provide insights into the epidemiology of these infections. International and national scientific databases were searched, and twenty-six articles in peer-reviewed journals, one conference paper, and one D.V.M. thesis were included in the study. In total, 10 species belonging to seven genera, including Dictyocaulus, Deraiophoronema, Protostrongylus, Crenosoma, Eucoleus, Aelurostrongylus, and Metastrongylus, were reported in the respiratory tract or feces of humans, domestic animals (i.e., camels, equids, dogs, and cats), and wildlife species (i.e., hedgehogs, wild boars, and hares). Most of the studies (22/28) were performed using post-mortem examinations. The overall prevalence of respiratory nematode infection varied according to animal species in camels (14.83%), equids (13.31%), dogs (5%), wild boars (45.66%), hedgehogs (42.57%), and hares (1.6%). In addition, pulmonary capillariasis caused by Eucoleus aerophilus was reported in a 9 year old child. The prevalence of lungworm species in domestic camels, equids, and dogs, combined with a lack of labeled anthelmintic products, supports the need to improve our understanding of these important nematode parasites and inform the development of sustainable control strategies. From a zoo and wildlife medicine point of view, there is a shortage of information about the presence and prevalence of lungworm infections in the majority of mammalian species, pending epidemiological studies that integrate classical parasitology and molecular methods.

Endoparasite Infections of the European Hedgehog ( Erinaceus europaeus) in Central Italy. Animals (Basel) 2021; 11:ani11113171. [PMID: 34827903 PMCID: PMC8614308 DOI: 10.3390/ani11113171] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2021] [Revised: 11/01/2021] [Accepted: 11/04/2021] [Indexed: 11/16/2022] Open
Abstract
Simple Summary The European hedgehog is a very common animal in Europe. This animal usually lives in woods but often it is possible to find it in gardens and parks in urban areas. Few studies describe parasites infecting the European hedgehog in Italy. In the present study, endoparasite infections and associated lesions were investigated in hedgehogs from two different regions of central Italy (Latium and Tuscany), where no investigations had been performed before. Several helminth and protozoan species were identified in the intestine and respiratory tract of the animals analyzed. The presence of the respiratory worm Crenosoma striatum was found to be associated with bronchial lesions. This study contributed to the knowledge of parasitic infections of the European hedgehog, the most frequently hospitalized animal in wildlife rescue centers. Abstract 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.

Abstract
From April 2009 to December 2011, 44 dead hedgehogs (Erinaceus europaeus) were collected incidentally from areas of Urmia, Iran. The overall prevalence of helminth infections was 95.0%. Specific parasites and their prevalences were: Physaloptera clausa (93.0%), Crenosoma striatum (61.0%), Capillaria aerophila (9.0%), Capillarias spp. (4.0%), Brachylaemus erinacei (2.0%) and Hymenolepis erinacei (16.0%). There were no significant differences in helminth occurrence between hedgehog sexes, either in single or in mixed infections (p > 0.05). The mixed infection involving Crenosoma striatum and P. clausa occurred significantly more frequently than other mixed infection (p < 0.05). There were significant differences in prevalence among seasons, with the highest prevalence in summer and spring especially among P. clausa and C. striatum (p < 0.05).

Abstract
Hedgehogs are small, nocturnal mammals that become popular in the world and have significant role in transmission of zoonotic agents. Some of the agents are transmitted by ticks and fleas such as rickettsial agents. For these reason, a survey on ectoparasites in European hedgehog (Erinaceus europaeus) carried out between April 2006 and December 2007 from different parts of Urmia city, west Azerbaijan, Iran. After being euthanized external surface of body of animals was precisely considered for ectoparasites, and arthropods were collected and stored in 70% ethanol solution. Out of 34 hedgehogs 23 hedgehogs (67.70%) were infested with ticks (Rhipicephalus turanicus). Fleas of the species Archaeopsylla erinacei were found on 19 hedgehogs of 34 hedgehogs (55.90%). There was no significant differences between sex of ticks (p > 0.05) but found in fleas (p < 0.05). The prevalence of infestation in sexes and the body condition of hedgehogs (small, medium and large) with ticks and fleas did not show significant differences (p > 0.05). Highest occurrence of infestation in both tick and flea was in June. Among three seasons of hedgehog collection significant differences was observed (p < 0.05). The result of our survey revealed that infestation rate in hedgehog was high. According to zoonotic importance of this ectoparasite and ability to transmission of some pathogens, more studies are needed to investigate hedgehog parasites in different parts of Iran.
