Phylogenetic Systematic Analysis Of The Trichostrongylidae (Nematoda), With An Initial Assessment Of Coevolution And Biogeography, Eric P. Hoberg, J. Ralph Lichtenfels
Phylogenetic Systematic Analysis Of The Trichostrongylidae (Nematoda), With An Initial Assessment Of Coevolution And Biogeography, Eric P. Hoberg, J. Ralph Lichtenfels
Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
Phylogenetic analysis of the subfamilies of the Trichostrongylidae based on 22 morphological transformation series produced a single cladogram with a consistency index (CI) = 74.2%. Monophyly for the family was supported by the structure of the female tail and copulatory bursa. Two major clades are recognized: the Cooperiinae clade with the basal Cooperiinae and Libyostrongylinae + Trichostrongylinae, and the Graphidiinae clade with the basal Graphidiinae and Ostertagiinae + Haemonchinae. Dendrograms presented by Durette- Desset (1985) (CI = 56.1%) and Lichtenfels (1987), based on the key to the Trichostrongylidae by Gibbons and Khalil (1982) (CI = 59.0%), were found to be …
Escherbothrium Molinae N. Gen. Et N. Sp. (Eucestoda: Tetraphyllidea: Triloculariidae) In Urotrygon Chilensis (Chondrichthyes: Myliobatiformes: Urolophidae) From The Gulf Of Nicoya, Costa Rica, Reva Berman, Daniel R. Brooks
Escherbothrium Molinae N. Gen. Et N. Sp. (Eucestoda: Tetraphyllidea: Triloculariidae) In Urotrygon Chilensis (Chondrichthyes: Myliobatiformes: Urolophidae) From The Gulf Of Nicoya, Costa Rica, Reva Berman, Daniel R. Brooks
Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
Cestodes collected in spiral valves of the stingray Urotrygon chilensis from the Pacific coast of Costa Rica represent an undescribed species of Tetraphyllidea. By possessing more than 2 loculi as well as an apical sucker on each bothridium, the new species is diagnosably distinct from all other tetraphyllidean genera; therefore, a new genus is proposed for it. The new species also possesses globular structures irregularly arranged on the surface of the bothridia. We found similar structures on the bothridial faces of Trilocularia acanthiaevulgaris, possibly indicating phylogenetic relationships with the new species. This possibility is enhanced by the observation that …
Description Of A New Blood-Fluke, Cruoricola Lates N. G., N. Sp. (Digenea: Sanguinicolidae), From Sea-Bass Lates Calcarifer (Bloch, 1790) (Centropomidae), Brett W. Herbert, Faizah M. Shaharom-Harrison, Robin M. Overstreet
Description Of A New Blood-Fluke, Cruoricola Lates N. G., N. Sp. (Digenea: Sanguinicolidae), From Sea-Bass Lates Calcarifer (Bloch, 1790) (Centropomidae), Brett W. Herbert, Faizah M. Shaharom-Harrison, Robin M. Overstreet
Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
A new blood-fluke, Cruoricola lates n. g., n. sp., is described from sea-bass Lates calcarifer cultured in Malaysia. It is also found in Thailand and Australia. All fish examined over 15 cm in length were infected in the type-locality. This sanguinicolid is differentiated from other genera by the spherical seminal vesicle; the large, single testis extending beyond the intestinal caeca; the medial, bi-lobed ovary; and the single column of submarginal, laterally directed, evenly spaced spines. It has separate genital pores which are close together. Adults are found predominantly in the mesenteric venules of the venous circulation. Juveniles are commonest in …

A New Species Of Vexillata (Nemata: Ornithostrongylidae) From The Coarse-Haired Pocket Mouse Chaetodipus Hispidus In New Mexico, Scott Lyell Gardner, Edward B. Fong, Luma Al-Banna, Stacie R. Raymond
Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
Individuals of a new species of trichostrongyloid nematode of the genus Vexillata were collected from the intestines of the coarse-haired pocket mouse, Chaetodipus hispidus, from eastern New Mexico. This new species possesses general features of the genus Vexillata but may be recognized as distinct from all other species by unique features of the dorsal ray of the caudal bursa and the synlophe.
Experimental Infection Of Contracaecum Tipapillatum (Nematoda: Anisakinae) From Mexico In The Domestic Cat, Victor Manuel Vidal-Martinez, David Osorio-Sarabia, Robin M. Overstreet
Experimental Infection Of Contracaecum Tipapillatum (Nematoda: Anisakinae) From Mexico In The Domestic Cat, Victor Manuel Vidal-Martinez, David Osorio-Sarabia, Robin M. Overstreet
Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
Juveniles of Contracaecum multipapillatum infected the Mayan cichlid (Cichlasoma urophthalmus) and adults infected the olivaceous cormorant (Phalacrocorax olivaceus) and the great egret (Casmerodius albus) in the coastal lagoon at Celestun, State of Yucatan, Mexico. All are new host records, and, even though the geographic locality record of Mexico for the species has not been published, unidentified but presumably conspecific specimens have been reported from there. When juveniles of C. multipapillatum were fed to a kitten, but not rats, ducks, or chickens, they developed into adults. Measurements and morphological data are provided on the specimens …

Effect Of Baculovirus Penaei On Growth And Survival Of Experimentally Infected Postlarvae Of The Pacific White Shrimp, Penaeus Vannamei, Kenneth C. Stuck, Robin M. Overstreet
Effect Of Baculovirus Penaei On Growth And Survival Of Experimentally Infected Postlarvae Of The Pacific White Shrimp, Penaeus Vannamei, Kenneth C. Stuck, Robin M. Overstreet
Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
In a series of experiments conducted to investigate age and size-dependent effects of the baculovirus BP on postlarvae of the Pacific white shrimp, Penaeus vannamei, six groups of specific pathogen-free shrimp of different ages (mysis 2–3 through PL 25) were exposed to the virus and cultured for 15 to 21 days. All BP-exposed groups of early postlarvae (PL 9 or younger) became heavily infected within 2–5 days of initial exposure to the virus, and some of those groups experienced high mortalities compared to the noninfected controls. Postlarvae that survived the infection had highly variable and significantly reduced growth, as …
Paraophioidina Scolecoides N. Sp., A New Aseptate Gregarine From Cultured Pacific White Shrimp Penaeus Vannamei, Timothy C. Jones, Robin M. Overstreet, Jeffrey M. Lotz, Paul F. Frelier
Paraophioidina Scolecoides N. Sp., A New Aseptate Gregarine From Cultured Pacific White Shrimp Penaeus Vannamei, Timothy C. Jones, Robin M. Overstreet, Jeffrey M. Lotz, Paul F. Frelier
Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
The aseptate gregarine Paraophloidina scolecoides n. sp. (Eugregarinorida: Lecudinidae) heavily infected the midgut of cultured larval and postlarval specimens of Penaeus vannamei from a commercial 'seed-production' facility in Texas, USA. It is morphologically similar to P. korotneffi and P. vibiliae, but it can be distinguished from them and from other members of the genus by having gamonts associated exclusively by lateral syzygy. Shrimp acquired the infection at the facility; nauplii did not show any evidence of infection, but protozoea, mysis, and postlarval shrimp had a prevalence and intensity of infection ranging from 56 to 80 % and 10 to …
Choanotaenia Atopa N. Sp. (Cestoda: Dilepididae) From A Domestic Cat In Kansas, Robert L. Rausch, R. D. Mckown
Choanotaenia Atopa N. Sp. (Cestoda: Dilepididae) From A Domestic Cat In Kansas, Robert L. Rausch, R. D. Mckown
Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
Choanotaenia atopa (Cestoda: Dilepididae) is described (host: domestic cat from the vicinity of Manhattan, Kansas); its natural host is presumed to be a rodent. Choanotaenia atopa is morphologically similar to cestodes of 6 species, all from rodents, formerly placed in the genus Rodentotaenia Matevosian, 1953, and subsequently removed to the genera Choanotaenia Railliet, 1896, or Monopylidium Fuhrmann, 1899. The systematic position of those cestodes is discussed; Monopylidium and Rodentotaenia are treated as synonyms of Choanotaenia. Choanotaenia atopa is distinguished by size and form of rostellar hooks, regularly alternating genital pores, and other characters in genital organs.

Two New Species And Temporal Changes In The Prevalence Of Eimerians In A Free-Living Population Of Townsend's Ground Squirrels (Spermophilus Townsendii) In Idaho, P. G. Wilber, Ben Hanelt, B. Van Horne, Donald W. Duszynski
Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
More than 1,180 fecal samples were collected from 253 juvenile and 384 adult Townsend's ground squirrels (Spermophilus townsendii) at the Snae Snake River Birds of Prey Area near Boise, Idaho, from February to June 1992. Oocysts of 7 eimerians were observed. Five are new host records (Eimeria beecheyi, Eimeria bilamellata, Eimeria callospermophili, Eimeria lateralis, and Eimeria morainensis), 2 species are described here as new, and new structural information on E. morainensis is added. Sporulated oocysts of Eimeria adaensis n. sp. are ovoidal, 19.6 x 22.7 (16-22 x 18-26) μm with sporocysts ellipsoidal …
A New Species Of Heterorhabditis From The Hawaiian Islands, Scott Lyell Gardner, S. Patricia Stock, Harry K. Kaya
A New Species Of Heterorhabditis From The Hawaiian Islands, Scott Lyell Gardner, S. Patricia Stock, Harry K. Kaya
Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
A new species of nematode of the genus Heterorhabditis (Nemata: Heterorhabditidae) was found during a survey of the soil entomopathogenic nematode fauna of the Hawaiian Islands. Heterorhabditis hawaiiensis sp. n. can be separated from all other species of Heterorhabditis by the length of the infective juvenile and the morphological characters of the spicules, gubemaculum, and bursa. Random amplified polymorphic DNA (RAPD) fragment analysis showed that this species also has a distinct genetic pattern in RAPD bands relative to the other 6 species or isolates of Heterorhabditis that were compared.
Echinococcus Granulosus (Taeniidae) And Autochthonous Echinococcosis In A North American Horse, Eric P. Hoberg, S. Miller, M. A. Brown
Echinococcus Granulosus (Taeniidae) And Autochthonous Echinococcosis In A North American Horse, Eric P. Hoberg, S. Miller, M. A. Brown
Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
We report the first documented case of autochthonous echinococcosis in a horse of North American origin. Three fully maturll and viable unilocular hydatid cysts of Echinococcus granulosus (Batsch, 1786) were an incidental finding at necropsy in the liver of a 14 year-old gelding thoroughbred that had been foaled in Virginia and raised in Maryland. Protoscolices were armed with two rows of 28-37 rostellar hooks; small hooks measured 23-30 μm; large hooks measured 26-33 μm. Morphologically, these were compatible with rostellar armature considered typical for the equine strain of E. granulosus currently known primarily from the United Kingdom. This horse had …

New Morphological Characters For Identifying Individual Specimens Of Haemonchus Spp. (Nematoda: Trichostrongyloidea) And A Key To Species In Ruminants Of North America, J. Ralph Lichtenfels, P. A. Pilitt, Eric P. Hoberg
Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
The large stomach worms Haemonchus contortus, Haemonchus placei, and Haemonchus similis are important pathogens of cattle and sheep. This paper describes characteristics of surface cuticular ridges (synlophe), which for the first time provide morphological criteria for identifying individual adult specimens of either sex. The diagnostic patterns of the synlophe on the anterior half of specimens can be observed at 400 x in temporary mounts on glass slides. The synlophe can be studied in cleared preserved specimens or in living or freshly thawed frozen specimens mounted in water. The synlophe of H. contortus has 30 ridges in the region …

Hepatocellular Neoplasm In A Wild-Caught Sheepshead Minnow (Cyprinodon Variegatus) From The Northern Gulf Of Mexico, Marcos F.T. Oliveira, William E. Hawkins, Robin M. Overstreet, William W. Walker
Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
The sheepshead minnow, Cyprinodon variegatus, is a widely distributed small fish species that inhabits estuaries and inshore waters from New England to northern South America. This species has been used extensively in aquatic environmental toxicity and carcinogenicity tests (Couch et al., 1981; Courtney and Couch, 1984). Hepatic neoplasms have been induced in the sheepshead minnow by exposure to several known chemical carcinogens including diethylnitrosamine (Couch and Courtney, 1987), methylazoxymethanolacetate (Hawkins etal., 1985), and dimethylbenz(a)anthracene (Hawkins et al., 1991). Because of its widespread distribution, limited home range, and proven sensitivity to carcinogens, the sheepshead minnow appears to be …
A New Coccidian (Apicomplexa: Eimeriidae) In The Northern Pocket Gopher (Thomomys Talpoides) And A Comparison Of Oocyst Survival In Hosts From Radon-Rich And Radon-Poor Soils, P. G. Wilber, K. Mcbee, D. J. Hafner, Donald W. Duszynski
A New Coccidian (Apicomplexa: Eimeriidae) In The Northern Pocket Gopher (Thomomys Talpoides) And A Comparison Of Oocyst Survival In Hosts From Radon-Rich And Radon-Poor Soils, P. G. Wilber, K. Mcbee, D. J. Hafner, Donald W. Duszynski
Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
Forty (93%) of 43 northern pocket gophers (Thomomys talpoides) from the Jemez Mountains, Sandoval County, New Mexico (USA), had coccidian oocysts in their feces when examined. We describe this parasite, Eimeria jemezi, n. sp. Sporulated oocysts were subspheroidal, 13.3 by 12.2 (10 to 17 by 9 to 15) ım, with sporocysts ellipsoidal, 7.1 by 4.4 (5 to 9 by 4 to 5) μm; micropyle and oocyst residuum were absent, but polar bodies, Stieda bodies and sporocyst residua were present. All gophers were collected from two sites of similar habitat 7 km apart. One site (R+) had a …
