Occurrence of Eucoleus aerophilus in wild and domestic animals: a systematic review and meta-analysis. Parasit Vectors 2023; 16:245. [PMID: 37475031 PMCID: PMC10360280 DOI: 10.1186/s13071-023-05830-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2023] [Accepted: 06/06/2023] [Indexed: 07/22/2023] Open
Abstract
BACKGROUND Eucoleus aerophilus (syn. Capillaria aerophila) is a nematode with a worldwide geographical distribution. It causes a disease called lung capillariosis by affecting the respiratory tract of wild and domestic animals, and has also occasionally been described in humans. Despite steady increases in knowledge of the morphology of this neglected parasite, many aspects are still poorly understood. Epidemiological data regarding, for example, geographic distribution, range of hosts, clinical relevance and the actual zoonotic potential of this nematode are scarce and incomplete. METHODS This article is a systematic review based on the screening of three databases (PubMed, Web of Science and Science Direct) to identify eligible studies published from 1973 to the end of 2022. RESULTS From a total of 606 studies describing the occurrence of E. aerophilus, 141 articles from 38 countries worldwide were included in this meta-analysis, all of which presented results obtained mainly with flotation and necropsy. Due to the occurrence of E. aerophilus in many different species and different matrices (lungs and faeces), we decided to conduct the meta-analysis separately for each species with a given matrix. This systematic review confirmed the status of the Red fox as the main reservoir and main transmitter of E. aerophilus (average prevalence of 43% in faeces and 49% in lungs) and provided evidence of a higher prevalence of E. aerophilus in wild animals in comparison to domestic animals, such as dogs (3% in faeces) and cats (2% in faeces and 8% in lungs). Previous studies have investigated many host-related factors (age, sex, environmental/living conditions) in relation to the prevalence of E. aerophilus, but they show wide variations and no simple relationship has been demonstrates. Furthermore, mixed infections with other pulmonary nematodes, such as Crenosoma vulpis and/or Angiostrongylus vasorum, are reported very frequently, which greatly complicates the diagnosis. CONCLUSIONS This systematic review focused on identifying data gaps and promoting future research directions in this area. To the best of our knowledge, this is the first systematic review that evaluates and summarizes existing knowledge on the occurrence and prevalence of E. aerophilus in wild and domestic animals originating from different geographical locations worldwide.

Abstract
In the present study, 64 golden jackals were examined for intestinal helminths in three regions of Vojvodina, Serbia. Among the examined jackals 57.8% were infected with at least one parasite species. Using the intestinal scraping technique (SCT), eight species of intestinal helminths were found: Alaria alata (7.8%), Toxascaris leonina (9.4%), Toxocara canis (4.7%), Uncinaria stenocephala (20.3%), Echinococcus multilocularis (14.1%), Mesocestoides sp. (42.2%), Taenia pisiformis, and Taenia hydatigena (the overall prevalence of Taenia infection was 6.3%). To the best of our knowledge, this is the first report of T. leonina in jackals from Serbia. In comparison with the SCT results, coprological tests were less sensitive and specific for parasite identification, as only two nematode species (T. leonina and T. canis) as well as ancylostomatid and taeniid eggs were identified. The total prevalence of intestinal helminths was higher in males (71.9% males, 45% females), but the difference was not statistically significant (χ 2 = 3.76; P = 0.052). Co-infection with two species of intestinal helminths was found in 35% of the examined golden jackal individuals, three-species co-infection was demonstrated in 21.6%, whereas four-species co-infection was detected in 2.7% of the golden jackals examined. Echinococcus multilocularis has previously been recorded in jackals and foxes in Serbia, but only in Vojvodina. Our results corroborate the findings of previous studies, and indicate that the Vojvodina Province, more specifically the Srem region, is probably a high-risk area for E. multilocularis transmission to humans.

Efficacy of milbemycin oxime/afoxolaner chewable tablets (NEXGARD SPECTRA ®) against Capillaria aerophila and Capillaria boehmi in naturally infected dogs. Parasit Vectors 2021; 14:143. [PMID: 33676579 PMCID: PMC7937313 DOI: 10.1186/s13071-021-04648-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2020] [Accepted: 02/16/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Capillaria aerophila and Capillaria boehmi parasitize the respiratory system of wild and domestic carnivores. Capillaria aerophila inhabits the trachea and bronchi of dogs and cats, while C. boehmi affects the nasal cavities and sinuses of dogs. In dogs the infection may be subclinical or characterized by varying respiratory distress. METHODS The present study evaluated the efficacy of an oral formulation containing milbemycin oxime and afoxolaner (NEXGARD SPECTRA®) in dogs naturally infected with C. aerophila and/or C. boehmi from three enzootic areas of Italy. Dogs were enrolled pending fecal examination and molecular confirmation of respiratory capillarioses. Dogs were allocated in two groups: Group 1 (G1, 25 dogs), treated with a negative control product with no anthelmintic activity (afoxolaner, NEXGARD®), and Group 2 (G2, 26 dogs), treated with NEXGARD SPECTRA®. At the day of treatment administration (Day 0), all dogs were clinically examined. Dogs were again subjected to clinical and fecal examinations at Days 28 (± 4) and 56 (± 2). The primary criterion for treatment efficacy was the reduction of fecal Capillaria egg counts in G2 compared with G1. The regression of/recovery from baseline clinical signs was considered as a further efficacy criterion. RESULTS Percentage reduction of fecal Capillaria egg counts in the NEXGARD SPECTRA® group compared to the control group was > 97% on Day 28 and 100% on Day 56, respectively (p < 0.05 for both time points). Twelve of the 13 dogs in the NEXGARD SPECTRA® group with respiratory signs prior to treatment were free of clinical signs at the end of the study. Conversely, the six control group dogs with respiratory signs prior to treatment remained symptomatic. CONCLUSIONS Results of the present study showed that NEXGARD SPECTRA® was safe and highly efficacious in the reduction of C. aerophila and C. boehmi eggs after one treatment with a complete reduction of the egg output after the second administration associated with a recovery from respiratory signs.

Clinical-parasitological Screening for Respiratory Capillariosis in Cats in Urban Environments. Helminthologia 2020; 57:322-334.

Abstract
Respiratory capillariosis is a widely distributed zoonotic parasitic disease caused by the nematode Capillaria aerophila (Trichocephalida, Trichuridae) that commonly infects wild carnivores but also cats and dogs. This retrospective study aims to describe cases of respiratory capillariosis in cats from the city of Belgrade, Serbia. Between 2015 and 2019, a total of 155 pet cats with or without respiratory symptoms were submitted to physical examination and parasitological examination of the feces. All cats lived indoor but had free access to outdoor. In suburban settlements, wild carnivores commonly share their living environments with owned cats and dogs. It can be assumed that more intense urbanization spreading into the natural habitats of will carnivores creates the opportunity for closer and more frequent contacts between the population of cats and feral carnivores which might increase the risk of feline contamination. The findings confirm the existence of capillaries in cats in urban areas of the city of Belgrade, contribute to a better understanding of the epidemiology of this nematode and warn that, because of close contacts between cats of pets and humans, capillaries can cause human infection.

Vet Parasitol 2020; 281:109103. [PMID: 32299042 DOI: 10.1016/j.vetpar.2020.109103] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2020] [Revised: 04/01/2020] [Accepted: 04/02/2020] [Indexed: 12/31/2022]
Abstract
Despite morphological differences of eggs and adults, Capillaria boehmi infections have been occasionally misdiagnosed as C. aerophila infections in the past. Capillaria boehmi is found in the nasal and paranasal sinuses of wild canids and dogs, which may suffer from nasal discharge, sneezing, epistaxis and, importantly, their scent can be impaired. In this study we present three challenging cases of nasal capillariosis in dogs, report and review the variable success of anthelmintic treatments and investigate C. boehmi prevalence in Swiss red foxes, considered as potential wild life reservoir. Out of two females and one male dog (all scent hounds, aged 3-9 years and weighing 19-31 kg), two dogs were previously coproscopically misdiagnosed with Trichuris infections. Two dogs showed clinical signs such as sneezing, coughing and impaired scent. From one dog adult living C. boehmi were obtained by nasal lavage. The identity of worms and eggs of all three dogs were genetically confirmed (18S rRNA, 100 % identity in 578 base pairs). Dogs 1-3 were followed-up for overall 54, 8, and 67 months, respectively. All dogs repeatedly excreted C. boehmi eggs in faecal samples despite treatments with the following compounds, in various dosage and retreatment protocols: fenbendazole, milbemycin oxime (orally), moxidectin/imidacloprid/ (spot-on) and levamisole (intramuscularly). The different anthelmintic compounds showed variable success regarding their effect on clinical outcome and on stopping egg excretion. Reinfections due to a contaminated environment could not be fully excluded. In winter 2016 and 2017, 218 foxes from the canton of Zurich, Switzerland, were examined. Tissues of nasal and paranasal sinuses were investigated for adult Capillaria specimens and eggs. We describe for the first time C. boehmi infections in Switzerland, observing a high prevalence (190/218, 87.2 %). Overall, 107 of 126 adults (84.9 %, 95 % Confidence Interval, CI: 77.5-90.7 %) and 83 of 92 youngsters (90.2 %, CI: 82.2-95.4 %) were infected. The presence of C. boehmi did not correlate with age (P = 0.209), but correlated significantly with sex: male foxes (102 of 107, 95.3 %, CI: 89.4-98.5 %) were significantly (P = 0.001) more often infected than females (88 of 111, 79.3 %, CI: 70.5-86.4 %). Worm burden ranged from 1 to 72 adult specimens (geometric mean: 5.7). In conclusion, C. boehmi infections can be mis- and/or underdiagnosed in dogs. Appropriate anthelmintic treatments, preventing coprophagia and egg contamination of the surroundings and performing coproscopic controls after treatments are fundamental aspects. Potentially, nasal washing may represent an auxiliary alternative. However, the successful elimination of C. boehmi infections in dogs remains challenging.

Abstract
This catalogue is concerned with the closely related angiostrongylid genera Angiostrongylus, Gallegostrongylus, Rodentocaulus and Stefanskostrongylus. Three species, Angiostrongylus cantonensis, A. costaricensis and A. vasorum, have attracted most attention because of their importance in human and domestic animal disease. Many of the remaining species are poorly known and the number of valid taxa is unclear. The catalogue lists all nomenclaturally available and unavailable genus-group and species-group names that have been applied to the above genera and the species included in them, indicating their current nomenclatural status and providing the rigorous nomenclatural basis for future work. The catalogue lists 14 published and nomenclaturally available genus-group names, with the above four treated as valid, the other ten being junior synonyms. There are 42 published species-group names: 36 are valid, two are junior synonyms, four are nomenclaturally unavailable. One additional species, described in Chabaudistrongylus (synonym of Angiostrongylus), is listed as incertae sedis in Angiostrongylidae. Also listed are two unpublished collection names. The catalogue provides bibliographic details for all published names, and for available names provides locations of type material, details of type localities, geographic distributions and details of type and other hosts, both definitive and intermediate, to the extent known. The catalogue is a work of nomenclature, not a revisionary taxonomic work. No new names or new combinations are proposed. The apparently new family-group synonymy of Cardionematinae with Angiostrongylidae is introduced, as are four genus-group synonymies, three with Angiostrongylus and one with Stefaskostrongylus.

Abstract
Among the wild canids, the red fox (Vulpes vulpes) is recognised as an important reservoir species for a range of parasites, including cardiopulmonary nematodes of public health and veterinary importance. As cross-host transmission between the red fox and domestic carnivores can play an important role in the epizootiology of cardiopulmonary parasitic diseases, the aim of the present investigations was to obtain data on the geographical distribution of cardiopulmonary nematodes of the red fox. The material for examination consisted of 83 foxes which were legally hunted at different locations during a three-month period from December 2017 to February 2018. The presence of four emerging species in Europe (Angiostrongylus vasorum, Crenosoma vulpis, Dirofilaria immitis and Eucoleus aerophilus) was revealed in red foxes of Serbia. Crenosoma vulpis and E. aerophilus were detected in foxes in both the plain and the mountainous areas across the country. Dirofilaria immitis is distributed in red foxes near alluvial rivers in Vojvodina province (northern Serbia). Angiostrongylosis caused by A. vasorum was demonstrated to exist in two enzootic foci with a high percentage of infected foxes in a plain area of northern Serbia. To the best of our knowledge, C. vulpis and A. vasorum were discovered for the first time in red foxes in central Serbia. The results provide strong evidence for veterinarians to take into consideration the parasitic nematodes discovered in red foxes in the differential diagnosis of diseases of companion animals. In the context of the 'One Health' approach the results related to the distribution of the zoonotic species E. aerophilus and D. immitis can be useful for medical epidemiology.
