“…15 Rodents such as the muskrat (Ondatra zibethicus), common vole (Microtus arvalis), eastern chipmunk (Tamias striatus), deer mouse (Peromyscus maniculatus), meadow vole (Microtus pennsylvanicus), woodchuck (Marmota monax), and lemmings (Dicrostonyx groenlandicus richardsonii, Lemmus trimucronatus trimucronatus) are reported intermediate hosts. 2,11 In addition, domestic dogs and cats are capable of serving as definitive hosts. 6,10 Although methods of transmission are not entirely clear, typically the definitive host sheds oncospheres in feces, which are then consumed by a rodent intermediate host.…”

“…7). Since there observed sufficient agreement in body size, character of the scolex, and size and numbers of rostellar hooks, and the consistency in occurrence of exogenous budding and localization of the cysticerci in the host, they were identified as Cysticercus longicollis Rudolphi, 1819, which is the larva of Taenia crassiceps (Zeder, 1800) [3,4].…”

“…The adult form of Tuenia crassiceps appears to be commonly found in red foxes and the larvae in various rodents including wild woodchucks [4]. Captured woodchucks maintained in animal facilities have sometimes accumulations of larval stage of Taenia crassiceps though animals born in laboratories are usually free of internal parasites since endoparasites infestations are uncommon in laboratories [9].…”

“…As intermediate hosts in northern America, the muskrat ( Ondatra zibethicus ), the common vole ( Microtus arvalis ), the eastern chipmunk ( Tamias striatus ), the deer mouse ( Peromyscus maniculatus ), the meadow vole ( Microtus pennsylvanicus ), but also the woodchuck ( Marmota monax ), and lemmings ( Dicrostonyx groenlandicus richardsonii, Lemmus trimucronatus trimucronatus ) were identified (Leiby and Whittaker, 1966; Albert et al, 1972). In Europe T. crassiceps cysticercosis seems to occur focally in variable prevalence in rodents.…”

Wild mustelids and canids are definitive hosts of Taenia and Versteria spp. while rodents act as natural intermediate hosts. Rarely, larval stages of these parasites can cause serious zoonoses. In Europe, four cases of Taenia martis cysticercosis have been diagnosed in immunocompetent women, and two cases in zoo primates since 2013. In North America, a zoonotic genotype related but distinct from Versteria mustelae has been identified in 2014, which had caused a fatal infection in an orangutan and liver- and disseminated cysticercoses in two severely immune deficient human patients in 2018, respectively. Additionally, we could attribute a historic human case from the USA to this Versteria sp. by reanalysing a published nucleotide sequence. In the last decades, sporadic zoonotic infections by cysticerci of the canid tapeworm Taenia crassiceps have been described (4 in North America, 8 in Europe). Besides, 3 ocular cases from North America and one neural infection from Europe, all in immunocompetent patients, 6 cutaneous infections were described in severely immunocompromised European patients. Correspondingly, besides oral infections with taeniid eggs, accidental subcutaneous oncosphere establishment after egg-contamination of open wounds was suggested, especially in cases with a history of cutaneous injuries at the infection site. Taenia multiceps is mainly transmitted in a domestic cycle. Only five human coenurosis cases are published since 2000. In contrast, T. serialis coenurosis (1 human case since 2000) is primarily transmitted by wild canids. The etiological diagnosis of exotic cysticercoses is challenging. Usually, clinical material does not allow for a morphological identification, and serological tests are not available. These limitations have partly been overcome by molecular tools. Without claiming any dramatic emergence of cysticercoses and coenuroses transmitted by wild carnivores, further sporadic cases of such ‘exotic’ infections have to be expected.
