Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
Cestodes are reported from Didelphis albiventris Lund, 1840 and Micoureus cinereus Temminck, 1824 (Marsupialia: Didelphidae) in Argentina. These include a new species of Mathevotaenia Akhumyan, 1946 (Cestoda: Anoplocephalata) as well as M. bivittata (Janicki, 1904) and an unknown hymenolepidid cestode. Mathevotaenia argentinensis n. sp. is characterized by a relatively narrow strobila, 18–37 mm in total length and 1.0–1.5 mm in maximum width, 135–163 craspedote proglottids, 19–27 testes, and a muscular genital atrium. This species differs from M. didelphidis (Rudolphi, 1819) in the disposition of the genital ducts between the excretory canals and in the entrance of the vagina into the …

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
Phylogenetic hypothesis of 23 populations corresponding to 18 species of the digenean Haematoloechus from America, Europe, and Africa, based on ribosomal DNA 28S partial sequences (~890 bp), is presented. Genetic divergence between the in-group and the out-groups ranged from 9.7 to 14.5% and within the in-group, from 0.9 to 12.2%. Eight most parsimonious trees 569 steps long were obtained, with a consistency index of 72%. Groups in the tree are not congruent with those in previous classification schemes of species in the genus, based on a small number of morphological characters. For this subset of Haematoloechus,/i> species, plesiomorphic hosts are …
Lessons From A Quiet Classic, Daniel R. Brooks
Lessons From A Quiet Classic, Daniel R. Brooks
Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
Parasitology has a rich tradition of studies linking taxonomy, ecology, and life cycles and development. This tradition has produced an enormous amount of empirical evidence demonstrating that parasites form highly integrated reproductive-developmental-ecological systems that are highly persistent through space and time. As well, phylogenetic studies of parasites, especially of parasitic platyhelminths, represent 1 of the most progressive areas of systematic biology. Consequently, parasitologists should be at the forefront of research in evolutionary developmental biology (evo-devo) and integrative biology, and parasite systems should be model systems of choice for those research programs. Species of the digenean, Alloglossidium, provide a superb …
First Report Of A Species Of Folliculovarium Gu & Shen, 1983 (Bucephalidae: Prosorhynchinae) From European Marine Waters, With The Description Of F. Mediterraneum N. Sp., Pierre Bartoli, Robin M. Overstreet, David I. Gibson

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
Folliculovarium mediterraneum n. sp. is described and figured in detail from the intestine of the Mediterranean moray eel Muraena helena (Muraenidae) in the Scandola Nature Reserve, off Corsica in the western Mediterranean. This new species closely resembles F. gymnothoracis Gu & Shen, 1983 and F. xishaense Gu & Shen, 1983 from marine fishes off China, but it may differ from both in not having specialized circum-rynchal spines. It differs from the former by having slightly larger eggs and a longer esophagus, and from F. xishaense by having tegumental spines, a longer esophagus, and a nonrelated host (an eel rather than …
Taxonomic Revision Of Rhinebothroides (Eucestoda: Tetraphyllidea: Phyllobothriidae), Parasites Of Neotropical Freshwater Stingrays (Rajiformes: Myliobatoidei: Potamotrygonidae), Fernando P.L. Marques, Daniel R. Brooks
Taxonomic Revision Of Rhinebothroides (Eucestoda: Tetraphyllidea: Phyllobothriidae), Parasites Of Neotropical Freshwater Stingrays (Rajiformes: Myliobatoidei: Potamotrygonidae), Fernando P.L. Marques, Daniel R. Brooks
Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
Extensive new collections of specimens of Rhinebothroides spp. from a wide range of Neotropical freshwater potamotrygonid stingrays in numerous localities permitted critical evaluation of the validity of the 7 nominal species in the genus. Some qualitative characters previously used in the taxonomy of this group are highly variable within and among populations, and most morphometric and meristic characters thought to have taxonomic value for this group overlapped among several previously defined nominal species. Characters that were consistent throughout populations and that clearly define morphotypes supported recognition of four species: R. freitasi (syn. R. circularisi and R. venezuelensis), R. glandularis …

Aspidoderid Nematodes From Bolivian Armadillos, With The Description Of A New Species Of Lauroia (Heterakoidea: Aspidoderidae), Scott Lyell Gardner, F. Agustin Jimenez-Ruiz
Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
One nine-banded armadillo (Dasypus novemcinctus) and 1 yellow armadillo (Euphractus sexcinctus) were necropsied in the field during an expedition to collect parasites of mammals in Bolivia. A total of 205 Aspidodera binansata Railliet and Henry, 1913 (Heterakoidea: Aspidoderidae), and 40 specimens of Lauroia bolivari n. sp. (Heterakoidea: Aspidoderidae) were recovered from the cecum and large intestines of D. novemcinctus and E. sexcinctus. Aspidodera esperanzae Fujita et al., 1995, is proposed as a junior synonym of A. binansata based on the structure of the cordons on the hood. Lauroia bolivari n. sp. has an undercut cephalic …

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
We describe two new species of leucochloridiid-like brachylaimoid digeneans parasitizing a variety of birds in the Área de Conservación Guanacaste, Costa Rica, each of which we assign to a new genus. According to Pojmanska's (Pojmanska, T. 2002a. Superfamily Brachylaimoidea Joyeux & Foley, 1930. In Keys to the Trematoda, D. I. Gibson, A. Jones, and R. A. Bray [eds.]. CAB International and The Natural History Museum, London, U.K., p. 31-36.) key for the Brachylaimoidea, we are unable to place either species in any family. One species most closely resembles members of Leucochloridium by having well-developed suckers, lacking an esophagus, and …

Coccidia In The Mammary Glands Of Shrews (Order: Insectivora), Donald W. Duszynski, William C. Marquardt
Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
Three of 6 female long-clawed shrews, Sorex unguiculatus Dobson, 1890, collected on the island of Hokkaido, Japan, were found to have unsporulated oocysts and sexual stages (both macro- and microgamonts) in varying stages of development of an unidentified coccidium in both lactating and non lactating mammary glands. Gamonts developed in the alveoli of the mammary glands, and oocysts were found in the lactiferous ducts and in pools of milk. Mature macrogamonts were 11.9 × 15.2 μm (10-14 × 14-20 μm), whereas completely developed microgamonts with many gametes were 14.8 × 16.8 μm (10-18 × 13-20 μm). Oocysts in tissue sections …

Taenia Pencei N. Sp. From The Ringtail, Bassariscus Astutus (Carnivora: Procyonidae), In Texas, U.S.A., Robert L. Rausch
Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
Taenia pencei n. sp. is described from the ringtail, Bassariscus astutus (Carnivora: Procyonidae), in western Texas, U.S.A., and its metacestode is characterized on the basis of specimens from Peromyscus cf. maniculatus in southern Oregon. Taenia pencei n. sp. apparently occurs exclusively in the ringtail, and it is the first cestode of the genus Taenia known from a member of the family Procyonidae. It is morphologically most similar to species of Taenia from mammals of the family Mustelidae in subclade two of the recently constructed phylogeny of that genus. Taenia pencei is distinguished from the nearctic Taenia taxidiensis in the badger …

Cystic Echinococcosis In The Arctic And Sub-Arctic, Robert L. Rausch
Cystic Echinococcosis In The Arctic And Sub-Arctic, Robert L. Rausch
Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
The northern biotype of Echinococcus granulosus occurs throughout the holarctic zones of tundra and taiga, from eastern Fennoscandia to the Bering Strait in Eurasia and in North America from arctic Alaska approximately to the northern border of the United States. The cycle of the cestode is complex in taiga at lower latitudes, because of the greater diversity of potential hosts. In the Arctic and Subarctic, however, four patterns of predator/prey relationships may be discerned. Two natural cycles involve the wolf and wild reindeer and the wolf and elk (moose), respectively. Where deer of the two species coexist, both are prey …

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
We report the use of six oligoprobes designed from intergenic spacer region sequences to identify fourth-stage larvae (L4) of the tribe Cyathostominae. Oligoprobes were designed for identification of the following species: Cylicocyclus ashworthi, Cylicocyclus nassatus, Cylicocyclus insigne, Cyathostomum catinatum, Cylicostephanus goldi, and Cylicostephanus longibursatus. A seventh probe was designed as a positive control to identify all these members of the Cyathostominae. The intergenic spacer region was amplified by PCR using conserved primers. Initially, three oligoprobes were used in Southern blot analysis. To facilitate high-throughput identification, these and a further four oligoprobes were developed for use in a PCR–ELISA. …

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
Tur megistoproctus, a new species of Laelapinae, is described from the pelage of the echimyid rodent Proechimys dimidiatus from the Atlantic forests of Ilha Grande, south of Rio de Janeiro. Measurements and illustrations are included for females and males. Another laelapine mite species, Tur turki Fonseca, co-occurred with T.megistoproctus in our studies and was recorded from the same host individuals and localities. These 2 laelapine mite species appear to be exclusively associated with a complex of echimyid rodent species (subgenus Trinomys) in the Atlantic forests of southeastern Brazil.

Phylogenetic Analysis Of The Metastrongyloidea (Nematoda: Strongylida) Inferred From Ribosomal Rna Gene Sequences, Ramon A. Carreno, Steven A. Nadler
Phylogenetic Analysis Of The Metastrongyloidea (Nematoda: Strongylida) Inferred From Ribosomal Rna Gene Sequences, Ramon A. Carreno, Steven A. Nadler
Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
Phylogenetic relationships among nematodes of the strongylid superfamily Metastrongyloidea were analyzed using partial sequences from the large-subunit ribosomal RNA (LSU rRNA) and small-subunit ribosomal RNA (SSU rRNA) genes. Regions of nuclear ribosomal DNA (rDNA) were amplified by polymerase chain reaction, directly sequenced, aligned, and phylogenies inferred using maximum parsimony. Phylogenetic hypotheses inferred from the SSU rRNA gene supported the monophyly of representative taxa from each of the 7 currently accepted metastrongyloid families. Metastrongyloid taxa formed the sister group to representative trichostrongyloid sequences based on SSU data. Sequences from either the SSU or LSU RNA regions alone provided poor resolution for …
