“…It has also been possible to experimentally infect hosts that do not normally harbour particular species in the wild ( Syphacia stroma in laboratory mice, Lewis, 1968). Nevertheless, while most rodents in nature harbour only their own specific species of Syphacia , casual infection by more generalist species (ecological fitting) may also have occurred (Araujo et al 2015; Weaver et al 2016).…”

Parasitic nematodes of the genusSyphaciaSeurat, 1916 infecting Muridae in the British Isles, and the peculiar case ofSyphacia frederici

Syphacia stroma (von Linstow, 1884) Morgan, 1932 and Syphacia frederici Roman, 1945 are oxyurid nematodes that parasitize two murid rodents, Apodemus sylvaticus and Apodemus flavicollis, on the European mainland. Only S. stroma has been recorded previously in Apodemus spp. from the British Isles. Despite the paucity of earlier reports, we identified S. frederici in four disparate British sites, two in Nottinghamshire, one each in Berkshire and Anglesey, Wales. Identification was based on their site in the host (caecum and not small intestine), on key morphological criteria that differentiate this species from S. stroma (in particular the tail of female worms) and by sequencing two genetic loci (cytochrome C oxidase 1 gene and a section of ribosomal DNA). Sequences derived from both genetic loci of putative British S. frederici isolates formed a tight clade with sequences from continental worms known to be S. frederici, clearly distinguishing these isolates from S. stroma which formed a tight clade of its own, distinct from clades representative of Syphacia obvelata from Mus and S. muris from Rattus. The data in this paper therefore constitute the first record of S. frederici from British wood mice, and confirm the status of this species as distinct from both S. obvelata and S. stroma.

“…This may be evidence of host switching which is known to occur within the genus Syphacia (Okamoto et al 2009;Weaver et al 2016). Lack of reference sequences for Mastophorus muris may mask identification of introduced taxa because such a cosmopolitan nematode may reveal cryptic diversity when molecularly typed.…”

Molecular characterization of cosmopolitan and potentially co-invasive helminths of commensal, murid rodents in Gauteng Province, South Africa

2018

Concurrent studies of helminth parasites of introduced and native rodent species are few and miss the opportunity to identify potential co-invasive parasite species. This study employed molecular tools to infer the phylogeny and elucidate the origin of potentially co-invasive parasites of commensal, murid rodents by assessing introduced Rattus norvegicus, Rattus rattus, Rattus tanezumi, and native Mastomys coucha in Gauteng Province, South Africa. Genotypes of Nippostrongylus brasiliensis recovered from R. norvegicus are nearly identical to those recovered from elsewhere in the world. The pinworms, Aspiculurus tetraptera, recovered from introduced R. tanezumi and R. rattus, Syphacia muris recovered from R. tanezumi, and Syphacia obvelata recovered from indigenous M. coucha have affiliations to those recovered of laboratory rodents from the USA and China. Syphacia obvelata was previously only known as a commensal endoparasite of laboratory rodents, and the S. muris genotype recovered from R. tanezumi in this study shows an affiliation to a genotype recovered from the same host species in Indonesia which is part of the native range. The study emphasizes the need for surveillance of potential co-invasive species and contributes in documenting genetic diversity of endoparasites of well-known hosts.

“…For the phylogenetic analysis of the total evidence data matrix (see Supplementary material), we used the options: new technology search and implicit enumeration in the program TNT, version 1.5 (available for free use via sponsorship of the Willi Hennig Society) (see Goloboff and Catalano, 2016 ). To insure that we used as many data as possible for the phylogenetic estimations, we employed a total evidence approach (Kluge, 1989 ) to develop and analyse our dataset which consisted of morphological continuous-mensural, discrete-qualitative (Weaver et al , 2016 ) and DNA sequence characters.…”

Cestodes of the genus Arostrilepis Mas-Coma and Tenora 1997 have a Holarctic distribution with 16 species occurring among 28 species of mostly arvicoline hosts. The type species of the genus is Arostrilepis horrida (von Linstow, 1901), described initially as Taenia horrida von Linstow, 1901, from murine rodents in Lower Saxony (Niedersachsen), Germany. Here we report the first helminth parasite from the mole-vole, Ellobius tancrei, in Mongolia which is the first subterranean rodent known to be infected with Arostrilepis in the Palearctic. In addition, we describe a new species: Arostrilepis batsaikhani n. sp. which most closely resembles A. microtis Gulyaev and Chechulin 1997, differing from this species with a genetic distance of about 4% (using cytochrome-b) and by having distinctly large cirrus spines, testes that are larger and fill the whole segment measured anterior–posterior and larger eggs.
