Tadaridanema Delicatus (Schwartz, 1927) N. Gen., N. Comb. (Trichostrongylina: Molineidae) Parasite Of Molossidae Bats, Jorge Falcon-Ordaz, Carmen Guzman-Cornejo, Luis Garcia-Prieto, Scott Lyell Gardner

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

On the basis of the revision of the type material of Anoplostrongylus delicatus Schwartz, 1927, and new specimens collected from Tadarida brasiliensis mexicana (Saussure, 1860) in 4 arid localities from Mexico, we describe a new genus (Tadaridanema n. gen.), to which A. delicatus is transferred (as Tadaridanema delicatus (Schwartz, 1927) n. gen., n. comb.). This new genus differs from all other genera included in noplostrongylinae by having ray 2 larger than ray 3. In addition, T. delicatus can be differentiated from the type species of Anoplostrongylus (Anoplostrongylus paradoxus (Travassos, 1918)) because it possess vestibular branches equal in length, cephalic inflation …

Aspidoderidae From North America, With The Description Of A New Species Of Aspidodera (Nematoda: Heterakoidea), F. Agustin Jimenez-Ruiz, Scott Lyell Gardner, Andrea S. Varela-Stokes

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Aspidodera sogandaresi n. sp. (Heterakoidea: Aspidoderidae) from Dasypus novemcinctus Linnaeus, 1758 is herein described. This nematode occurs in armadillos from as far south as the canal zone of Panama, north through central Mexico, and into the southern United States. Previously identified as Aspidodera fasciata (Schneider, 1866), this new species has blunt projections on the lips and lateral expansions at the distal tips of the spicules, whereas A. fasciata has conspicuous digitiform projections on the lips, and a terminal round expansion at the tips of the spicules. Other species of the family present in North America include Aspidodera binansata Railliet and …

Ecological Fitting As A Determinant Of The Community Structure Of Platyhelminth Parasites Of Anurans, Daniel R. Brooks, Virginia León-Règagnon, Deborah A. Mclennan, Derek Zelmer

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Host-parasite associations are assumed to be ecologically specialized, tightly coevolved systems driven by mutual modification in which host switching is a rare phenomenon. Ecological fitting, however, increases the probability of host switching, creating incongruences between host and parasite phylogenies, when (1) specialization on a particular host resource is a shared characteristic of distantly related parasites, and (2) the resource being tracked by the parasite is widespread among many host species. We investigated the effect of ecological fitting on structuring the platyhelminth communities of anurans from a temperate forest and grassland in the United States and tropical dry and wet forests …

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

This is the first report of Ancylostoma malayanum (Alessandrini, 1905), subgenus Ceylancylostoma (Lichtenfels, 1980) from wild brown bears Ursus arctos L. The bears were collected by shooting in Wassamu-Cho province (44 [degrees] 80 [minutes] 59 [seconds] N, 142 [degrees] 82 [minutes] 99 [seconds] E), Hokkaido, Japan, November, 2003.

Paracreptotrema Blancoi N. Gen., N. Sp. (Digenea: Plagiorchiformes: Allocreadiidae) In The Olomina, Priapichthys Annectens (Osteichthyes: Poeciliidae), From The Área De Conservación Guanacaste, Costa Rica, Anindo Choudhury, Gerardo Pérez Ponce De León, Daniel R. Brooks, Rita Daverdin

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

A new species of allocreadiid digenean is described from Priapichthys annectens (Regan) (Osteichthyes: Poeciliidae) in the Área de Conservación Guanacaste, Costa Rica. A new genus, Paracreptotrema is proposed to accommodate this species as well as Fellodistomum mendezi Songandares-Bernal, 1955, which was previously described from another poeciliid, Brachyrhaphis episcopi, in Panama. Paracreptotrema differs from all other nominal genera of Allocreadiidae by a combination of its symmetrical testes, restricted vitellaria, and the lack of oral lappets (muscular 'papillae') or other such appendages. Paracreptotrema blancoi n. sp. resembles Creptotrema creptotrema Travassos, Artigas and Pereira, 1928, but differs in lacking ventral oral lappets …

Bolek, Christopher M. Whipps, John J. Janovy Jr., Mike L. Kent, David Modrý

John Janovy Publications

During March 2001-April 2004, 164 adult anurans of 6 species (47 Rana blairi, 35 Rana catesbeiana, 31 Hyla chrysoscelis, 31 Pseudacris triseriata triseriata, 11 Bufo woodhousii, and 9 Acris crepitans blanchardi) from Pawnee Lake, Lancaster County, Nebraska, were surveyed for myxozoan parasites. Of these, 20 of 31 (65%) P. triseriata triseriata and 1 of 9 (11%) A. crepitans blanchardi were infected with a new species of Myxidium. Myxidium melleni n. sp. (Myxosporea) is described from the gallbladder of the western chorus frog, P. triseriata triseriata (Hylidae). This is the second species of Myxidium …

Post-Miocene Expansion, Colonization, And Host Switching Drove Speciation Among Extant Nematodes Of The Archaic Genus Trichinella, D. S. Zarlenga, B. M. Rosenthal, G. Larosa, E. Pozio, Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Parasitic nematodes of the genus Trichinella cause significant food-borne illness and occupy a unique evolutionary position at the base of the phylum Nematoda, unlike the free-living nematode Caenorhabditis elegans. Although the forthcoming genome sequence of Trichinella spiralis can provide invaluable comparative information about nematode biology, a basic framework for understanding the history of the genus Trichinella is needed to maximize its utility. We therefore developed the first robust and comprehensive analysis of the phylogeny and biogeographic history of Trichinella using the variation in three genes (nuclear small-subunit rDNA, and second internal transcribed spacer, mitochondrial large-subunit rDNA, and cytochrome oxidase …

Phylogenetic Approach To The Study Of Triatomines (Triatominae, Heteroptera) = Abordagem Filogenética Em Triatomíneos (Triatominae, Heteroptera), Ester Tartarotti, Maria Tercília Vilela De Azeredo-Oliveira, Carlos Roberto Ceron

Harold W. Manter Laboratory: Library Materials

Triatomines are insects belonging to the Hemiptera order, Heteroptera suborder, Reduviidae family and Triatominae subfamily. All members of this subfamily are hematophagous. Triatomines evolved from Reduviidae predators and they are probably polyphyletic in origin. The combination of anatomical, physiological and ethological factors observed in this group, as well as the plesiomorphic and apomorphic characters that differentiate the five tribes and fourteen triatomine genera reinforce the polyphiletic hypotesis. However if we consider the five groups of triatomines, the Rhodniini, Cavernicolini, Bolboderini, Linshcosteini and Alberproseniini tribes constitute monophyletic groups, while the Triatomini tribe is considered polyphyletic. The New World is the center …

A Coprological View Of Ancestral Pueblo Cannibalism, Karl Reinhard

Karl Reinhard Publications

As the object of my scientific study, I’ve chosen coprolites. It’s not a common choice, but to a paleonutritionist and archaeoparasitologist, a coprolite—a sample of ancient feces preserved by mineralization or simple drying—is a scientific bonanza. Analysis of coprolites can shed light on both the nutrition of and parasites found in prehistoric cultures. Dietary reconstructions from the analysis of coprolites can inform us about, for example, the origins of modern Native American diabetes. With regard to parasitology; coprolites hold information about the ancient emergence and spread of human infectious disease. Most sensational, however, is the recent role of coprolite analysis …

Systematics And Emerging Infectious Diseases: From Management To Solution, Daniel R. Brooks, Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

The crisis of emerging infectious disease stems from the absence of comprehensive taxonomic inventories of the world's parasites, which includes the world's pathogens. Recent technological developments raise hopes that the global inventory of species, including potential pathogens, can be accomplished in a timely and cost-effective manner. The phylogenetics revolution initiated by systematists provides a means by which information about pathogen transmission dynamics can be placed in a predictive framework. Increasingly, that information is widely available in digital form on the internet. Systematic biology is well positioned to play a crucial role in efforts to be proactive in the arena of …

Bionomics Of Larvae Of Parelaphostrongylus Odocoilei (Nematoda: Protostrongylidae) In Experimentally Infected Gastropod Intermediate Hosts, Emily J. Jenkins, S. J. Kutz, Eric P. Hoberg, L. Polley

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Parelaphostrongylus odocoilei is a protostrongylid parasite that has recently been recognized at several locations in sub-Arctic, but not Arctic, North America. We investigated factors that may determine the distribution of P. odocoilei, including suitable gastropod intermediate hosts, temperature requirements for larval development in gastropods, and larval emergence facilitating overwinter transmission. We collected and experimentally infected gastropods from a site in the sub- Arctic where P. odocoilei is at the northern limit of its distribution. Deroceras laeve, Catinella sp., and Euconulus cf. fulvus, but not members of the Pupillidae, were suitable intermediate hosts. We describe bionomics of larvae …

Selachohemecus Benzi N. Sp. (Digenea: Sanguinicolidae) From The Blacktip Shark Carcharhinus Limbatus (Carcharhinidae) In The Northern Gulf Of Mexico, Stephen A. Bullard, Robin M. Overstreet, John K. Carlson

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Selachohemecus benzi Bullard & Overstreet n. sp. infects the heart and kidney of the blacktip shark Carcharhinus limbatus in the northern Gulf of Mexico off Florida and Mississippi, USA. Specimens of S. olsoni Short, 1954, the only congener and only other named blood fluke reported from a chondrichthyan in the Gulf of Mexico, were collected from the heart of the Atlantic sharpnose shark Rhizoprionodon terraenovae from two new localities, Apalachicola Bay, Florida, and Mississippi Sound, Mississippi, USA. The new species differs from S. olsoni by having a larger body (1.4–3.8 mm long), robust tegumental body spines numbering 51–63 along each …

First Report Of Mites And Fleas Associated With Sigmodontine Rodents From Corrientes Province, Argentina, Marcela Lareschi, Donald Gettinger, Santiago Nava, Agustín Abba, Mariano L. Merino

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Fleas (Insecta: Siphonaptera) and mesostigmate mites (Acari: Laelapidae) are common ectoparasitic associates of sigmodontine rodents in the Neotropics of South America. In Argentina, most of the research on ectoparasitic arthropods has been carried out on rodents from Buenos Aires Province (Autino and Lareschi, 1998; Lareschi and Mauri, 1998), while only a few small studies have been done in other areas of the country, such as the northwest (Lareschi et al., 2003a), and the Monte Desert Biome in Mendoza Province (Lareschi et al., 2004). Unfortunately, very little information is available from the region between the Paraná and Uruguay rivers in northeastern …

Redescription Of Cryptocotyle Thapari Mcintosh, 1953 (Trematoda: Heterophyidae), In The River Otter Lutra Longicaudis From Bolivia, Scott Lyell Gardner, Peter T. Thew

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Cryptocotyle thapari McIntosh, 1953 (Digenea: Heterophyidae), collected originally from a South American otter that died at the U.S. National Zoo in Washington, D.C., is redescribed from specimens obtained from a river otter, Lutra longicaudis, collected from the Rı´o Matos in the Departamento de Beni, Bolivia. These individuals of C. thapari are slightly smaller than the type specimens, but they have similar features, including testes arranged in tandem and a well-defined ventrogenital sac. We redescribe this species because the original description was based on only 3 individuals, and the figures lacked detail. This is the first record of Cryptocotyle from …

A New Species Of Neohaematotrephus (Digenea: Echinostomiformes: Cyclocoelidae) In The Spotted-Sandpiper Actitis Macularia (Charadriiformes: Scolopacidae) From Venezuela, David Zamparo, Daniel R. Brooks

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Fischthal and Nasir (1974) reported Neohaematotrephus brasilianum (as Cyclocoelum brasilianum) in the spotted sandpiper Actitis macularia from Venezuela. Three voucher specimens from that report, deposited in the United States National Parasite Collection, however, differ from N. brasilianum by having the cirrus sac on the sinistral side of the body, which resembles N. facioi, N. arayae, and N. gendrei. The new species is similar to N. brasilianum by having vitelline follicles extending well anterior to the intestinal bifurcation and by having a short and laterally displaced cirrus sac whose posterior end does not reach the intestinal bifurcation, …

Glucocorticoid Hormone Levels Increase With Group Size And Parasite Load In Cliff Swallows, Samrrah A. Raouf, Linda C. Smith, Mary Bomberger Brown, John C. Wingfield, Charles R. Brown

School of Biological Sciences: Faculty Publications

Animals often cope with adverse events by releasing glucocorticoid hormones, which in turn promote increased energy assimilation. In captive animals, crowding also leads to increased glucocorticoid activity, probably because of increased levels of social competition. We investigated how group size and ectoparasite infestations affected endogenous levels of the glucocorticoid hormone, corticosterone, in colonial cliff swallows, Petrochelidon pyrrhonota, in southwestern Nebraska, USA. Parasites were removed from some colonies by fumigating nests. Baseline levels of corticosterone in breeding adults varied significantly with whether parasites were present, colony size (measured by total number of active nests at a site), and nesting stage. …

Seven New Species Of Eimeria Schneider, 1875 (Apicomplexa: Eimeriidae) From Colubrid Snakes Of Guatemala And A Discussion Of What To Call Ellipsoid Tetrasporocystic, Dizoic Coccidia Of Reptiles, I. M. Asmundsson, Donald W. Duszynski, J. A. Campbell

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

During a survey of Guatemalan herpetofauna in the summers of 1998–2000, 29 presumed new species of Eimeria Schneider, 1875 were found, seven of which have a distinct elongate-ellipsoidal shape (L/W ratio ≥ 1.7) and are described herein. Six of the seven new species are similar in oöcyst length, width and L/W ratio and sporocyst length, width and L/W ratio, lack a micropyle, oöcyst residuum, Stieda body, sub- and parastieda bodies, have a polar granule and sporocyst residuum, and their sporocysts appear to have dehiscence sutures. The seventh is slightly smaller and has sporocysts with a Stieda body. The new species …

Psettarium Anthicum Sp. N. (Digenea: Sanguinicolidae) From The Heart Of Cobia Rachycentron Canadum (Rachycentridae) In The Northern Gulf Of Mexico, Stephen A. Bullard, Robin M. Overstreet

Psettarium anthicum sp. n. (Digenea: Sanguinicolidae) infects the myocardium and atrial wall of the cobia Rachycentron canadum (Linnaeus, 1766) (Rachycentridae) in the northern Gulf of Mexico off Mississippi, USA. It is the first member of Psettarium Goto et Ozaki, 1930 reported from other than the Indian Ocean or Pacific Ocean and the second species of the genus reported from cobia. It differs from its congeners by the combination of having posterior caeca with lateral projections appearing as thorns in lateral view and the male pore anterior to the oötype. The species of Psettarium, P. japonicum (Goto et Ozaki, 1929) …

A Review Of Polylekithum Arnold 1934 And Its Familial Affinities Using Morphological And Molecular Data, With Description Of Polylekithum Catahoulensis Sp. Nov., Stephen S. Curran, Vasyl V. Tkach, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

The type material of Polylekithum ictaluri, P. halli, and Maculifer chandleri was examined from the United States National Parasite Museum, and we determined that the material was conspecific, making P. halli and M. chandleri junior subjective synonyms of P. ictaluri. Polylekithum catahoulensis sp. nov. was described from material collected from catfishes at the Catahoula Wildlife Refuge, LaSalle Parish, Louisiana, USA, and compared with P. ictaluri collected from catfishes in Reelfoot Lake, Obion County, Tennessee, USA, and the Pearl River, Hancock County, Mississippi, USA. Polylekithum catahoulensis had smaller eggs (77-–88 μm long by 51–-63 µm wide vs. 94–-108 …

Parelaphostrongylus Odocoilei In Columbia Black-Tailed Deer From Oregon, Jack A. Mortenson, Arthur Abrams, Benjamin M. Rosenthal, Detiger Dunams, Eric P. Hoberg, Robert J. Bildfell, Richard L. Green

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Documenting the occurrence of Parelaphostrongylus odocoilei has historically relied on the morphological examination of adult worms collected from the skeletal muscle of definitive hosts, including deer. Recent advances in the knowledge of protostrongylid genetic sequences now permit larvae to be identified. Dorsal-spined larvae (DSLs) collected in 2003–2004 from the lung and feces of six Columbian black-tailed deer (Odocoileus hemionus columbianus) from Oregon were characterized genetically. The sequences from unknown DSLs were compared to those from morphologically validated adults and larvae of P. odocoilei at both the second internal transcribed spacer (ITS-2) of ribosomal DNA and the mitochondrial cytochrome …

Sl1 Rna Gene Recovery From Enterobius Vermicularis Ancient Dna In Pre-Columbian Human Coprolites, Alena M. Iñiguez, Karl Reinhard, Marcelo Luiz Carvalho Gonçalves, Luiz Fernando Ferreira, Adauto Araújo, Ana Carolina Paulo Vincente

Karl Reinhard Publications

Enterobius vermicularis, pinworm, is one of the most common helminths worldwide, infecting nearly a billion people at all socio-economic levels. In prehistoric populations the paleoparasitological findings show a pinworm homogeneous distribution among hunter-gatherers in North America, intensified with the advent of agriculture. This same increase also occurred in the transition from nomad hunter-gatherers to sedentary farmers in South America, although E. vermicularis infection encompasses only the ancient Andean peoples, with no record among the pre-Colombian populations in the South American lowlands. However, the outline of pinworm paleo epidemiology has been supported by microscopic finding of eggs recovered from coprolites. …
