“…This morphologically based identifi cation was supported in our study by the molecular data showed that Canadian Baylisascaris devosi from volverines Gulo gulo L., 1758 were the most similar to the material from Kamchatka in the CoxI mtDNA sequence. It is worth to mention that according to the phylogenetic analysis of partial CoxI mtDNA, B. devosi formed the well supported clade with B. potosis described from the captive South American kinkajou (Tokiwa et al, 2014). The similarity in nucleotide sequences of three loci was congruent with the morphological similarity of these two species displayed in the similar distribution of postcloacal genital papillae, as well as the shape and number of denticles on the lip margins.…”

“…Kontrimavichus (1969) accepted the new genus and proposed to consider as Ascaris columnaris (Leidy, 1856) only parasites of skunks, having agreed that ascaridids of mustelids are to be considered as Baylisascaris devosi Sprent, 1952. Though this opinion was supported by Mozgovoy & Shakhmatova (1973), the specifi c binomial Ascaris columnaris was used in Russian literature for the ascaridids of sables during some time (Tranbenkova, 1987). The genus Baylisascaris Sprent 1968 includes eleven valid species of intestinal parasites of mammals.…”

“…The genus Baylisascaris Sprent 1968 includes eleven valid species of intestinal parasites of mammals. Apart from Baylisascaris tasmaniensis Sprent, 1970 from marsupials (Sprent,1970) and Baylisascaris laevis (Leidy, 1856) from rodents (Sprent, 1968), all remaining species were found parasitizing carnivores: pandas (Xie et al, 2011), bears (Perez et al, 2016), kinkajou (Tokiwa et al, 2014), skunks, raccoons and various mustelids: badgers, fi shers, sables, wolverines (Sprent, 1968). Sprent (1952) had demonstrated that 2 nd stage juveniles of B. devosi swallowed by mice moulted with the formation of 3rd stage juveniles and encapsulated in the muscles of these paratenic hosts.…”

SummaryThe nematodes of the genus Baylisascaris are common intestinal parasites of sables (Martes (M.) zibellina kamtschadalica Birula, 1916) on the entire territory of Kamchatka peninsula. Partial sequences of Cox I mitochondrial gene were used for molecular characterization of these nematodes, which confi rmed the identifi cation based on morphological data as B. devosi Sprent, 1952. Phylogenetic relationships of this Baylisascaris species were also inferred from the ITS rDNA and LSU rDNA sequences. SEM images were provided for taxonomically important morphological features.

“…are also commonly kept as pets and represent additional hosts of B. procyonis (dogs), B. potosis (kinkajous), or undetermined Baylisascaris spp. (coatis) that are able to eliminate eggs in their feces, potentially posing a risk of infection for humans (1,79,80,81). In contrast, B. procyonis is so extensively adapted to raccoons that they will continue to have the central role in the transmission of this parasite (1).…”

SUMMARYBaylisascaris procyonis, the raccoon roundworm, infects a wide range of vertebrate animals, including humans, in which it causes a particularly severe type of larva migrans. It is an important cause of severe neurologic disease (neural larva migrans [NLM]) but also causes ocular disease (OLM; diffuse unilateral subacute neuroretinitis [DUSN]), visceral larva migrans (VLM), and covert/asymptomatic infections.B. procyonisis common and widespread in raccoons, and there is increasing recognition of human disease, making a clinical consideration of baylisascariasis important. This review provides an update for this disease, especially its clinical relevance and diagnosis, and summarizes the clinical cases of human NLM and VLM known to date. Most diagnosed patients have been young children less than 2 years of age, although the number of older patients diagnosed in recent years has been increasing. The recent development of recombinant antigen-based serodiagnostic assays has aided greatly in the early diagnosis of this infection. Patients recovering with fewer severe sequelae have been reported in recent years, reinforcing the current recommendation that early treatment with albendazole and corticosteroids should be initiated at the earliest suspicion of baylisascariasis. Considering the seriousness of this zoonotic infection, greater public and medical awareness is critical for the prevention and early treatment of human cases.

“…Esta especie tiene una larga historia evolutiva con su hospedador, por lo cual, los efectos perniciosos sobre el mapache son menores (Kazacos 2001). Además, de B. procyonis, existen ocho especies más dentro del género Baylisacaris spp, el cual incluye el B. columnaris siendo su huésped definitivo las mofetas (Mephitis macroura); la especie B. potosís, recientemente descrita para las martillas (Potos flavus), todos ellos con potencial zoonótico (Kazacos 2001;Tokiwa, et al 2014). Para estas dos especies, sus hospederos definitivitos se encuentran distribuidos a lo largo de Mesoamérica.…”

Abstract:The zoonotic helminth Baylisacaris procyonis is a parasite in urban raccoons (Procyon lotor) of increasing public health concern. A new report alerts about the presence of these roundworms in urban raccoon populations in Costa Rica stressing the need to understand the parasite, its life cycle and preventive measures to avoid transmission to humans and pets. This is a brief review of the most remarkable features of this parasite and its negative effects on animal and public health. Additionally, emphasis is given on the best and most appropriate etiologic diagnostic methods in domestic animals, as well as treatment and prevention in dogs. This article is meant to raise awareness in public and animal health caretakers to consider Bayliascaris procyonis as differential diagnosis for larva migrans in Costa Rica.
