Angularella Audubonensis Sp. N. (Dilepididae) And Other Cestodes Of Cliff Swallows In Colorado, Jeffrey D. Stamper, Gerald D. Schmidt

Harold W. Manter Laboratory of Parasitology: Faculty Publications

One hundred forty-five cliff swallows, Petrochelidon pyrrhonota, were examined for cestodes in two separate surveys in Weld County, Colorado. Seven species representing four genera were found. Angularella audubonensis sp. n. is differentiated by the small size of the rostellar hooks (8.4-13.5 μm) and the medial relationship of the cirrus pouch to the osmoregulatory canals. Other species collected were Angularella beema, Anonchotaenia globata, Mayhewia ababili, Vitta magniuncinata, Vitta parvirostris and Vitta riparia. Seven new hosts and geographic distribution records were established for Colorado, and six new records were determined for North America.

A Checklist Of Parasites Of California, Oregon, And Washington Marine And Estuarine Fishes, Milton S. Love, Mike Moser

Harold W. Manter Laboratory of Parasitology: Faculty Publications

This report is a summary of the published records of parasites found from the marine and estuarine fishes of California, Oregon, and Washington. Coverage has not been limited to the western United States, but rather includes parasite reports from throughout each fish's range. Included is a host-parasite list and parasite-host cross index.

We have produced this survey because we felt there was a need for a single source which would list all the parasites infecting marine and estuarine fish from California, Oregon, and Washington. Pertinent sources are scattered over a number of journals, covering many years. Workers find it time …

Rhizonema Sequoiae N. Gen. N. Sp. From Coast Redwood Sequoia Sempervirens (D. Don) Endl., I. Cid Del Prado Vera, B. F. Lownsbery, Armand R. Maggenti

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Rhizonema sequoiae n. gen. n. sp. is described from the roots of Coast Redwood, Sequoia sempervirens (D. Don) Endl., growing near Lake Lagunitas, Marin County, California. Rhizonema females are annulated over their entire bodies, are wholly embedded in host tissue, and secrete an abundant amount of gel material. Mature females do not form a cyst. The vulva is located on a large posterior terminal cone, and the anus is on the dorsal vulval lip. Esophageal glands of the second-stage larvae fill more than half of the body cavity. Tails of the vermiform males are blunt, and a cloacal tubus is …

Aspects Of The Biology Of The Red Drum, Sciaenops Ocellatus, In Mississippi, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Several hundred specimens of the red drum from Mississippi were critically assessed. Regression equations for standard-length (SL) versus total-length differed between males and females and between small and large members of the same sex. Asingle regression line represented the weight-SL relationship for males with females. For condition coefficients to be helpful, fish had to be grouped at least by sex, season, and length or stage of maturity. By 12 months of age, most fish were about 30 to 32 cm SL and their distribution ranged throughout Mississippi Sound rather than being restricted to inshore bayou and marsh habitats like younger …

Aspects Of The Biology Of The Spotted Seatrout, Cynoscion Nebulosus, In Mississippi, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

About 3,000 specimens of the spotted seatrout from Mississippi Sound and adjacent water grouped by males and females had a nearly identical standard Iength (SL) versus total length (TL) relationship, although the equation for males in winter differed from that for those in other seasons. When investigating the SL-weight relationship, some differences occurred both among seasons and between sexes. Therefore, condition coefficients (K) were calculated to compare male and female groups according to their length and state of maturation on a seasonal basis. The hepatosomatic index (HSI) tended to increase with fish length, with relatively high values occurring in winter …

Organization Of Sporulated Oocysts Of Eimeria Funduli In The Gulf Killifish, Fundulus Grandis, William E. Hawkins, John W. Fournie, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Oocysts of Eimeria funduli were studied by transmission electron microscopy in naturally-infected livers of the Gulf killifish, Fundulus grandis. Tissues were cryo-processed because membranous structures in the oocyst appear to hinder routine fixation and embedment. The oocyst wall (about 25 nm thick) was adjacent to the host cell and consisted of an outer membrane that limited the host cell cytoplasm and an inner membrane separated from the outer membrane by a narrow space. In some specimens, dense material was applied to the inner face of the inner membrane. Individual sporocysts were surrounded by a membranous "veil" (about 25 nm …

Evaluation Of The Status Of Texanocotyle Pogoniae And Laterocotyle Padreinsulae (Trematoda: Aspidogastridae), Sherman S. Hendrix, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Simpson and McGraw (1979, Southwest. Nat. 24: 557-562) erected two genera for two new species of aspidogastrid trematodes infecting the black drum, Pogonias cromis (Linnaeus), along the Texan Gulf of Mexico coast. Examination of holotypes and paratypes of each reveals that the two species have been described previously and that the genera are invalid.

Gastrointestinal Helminths Of The Cougar, Felis Concolor L., In Northeastern Oregon, Robert L. Rausch, C. Maser, Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Helminths of nine species were identified from 39 cougars obtained in northeastern Oregon (Walbowa, Baker, and Union counties), viz., Taenia omissa Lühe, 1910 (100%); T. ovis krabbei Moniez, 1879 (61%); T. hydatigena Pallas, 1776 (10%); Mesocestoides lineatus (Goeze, 1782) (5%); Toxascaris leonina (von Linstow, 1902) (69%); Toxocara cati (Schrank, 1788) (15%); Physaloptera praeputialis von Linstow, 1889 (13%); Pterygodermatites affinis (Jagerskiold, 1904) (ca. 2%); and Trichinella sp. (larvae) (ca. 2%). In addition, undeveloped cestodes of the genus Taenia in 26 animals had lost rostellar hooks and could not be identified. Host-records, prevalence, and biological characteristics of some of the helminths are …

Occurrence And Pathogenicity Of Heligmosomoides Spp. (Nematoda: Heligmosomidae) Associated With Cecal Villi In Arvicolid Rodents, Robert L. Rausch, M. L. Johnson

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The host response to the nematodes Heligmosomoides hudsoni (Cameron, 1937) and H. johnsoni Rausch and Rausch, 1973 (Heligmosomidae) was investigated in their natural hosts, varying lemmings, Dicrostonyx spp., and heather voles, Phenucomys intermedius Merriam (Rodentia: Arvicolidae), respectively. The nematodes occupy the cecum of the host, where they coil tightly around the long cecal villi. In individual animaIs, the comparatively few villi occupied became much enlarged, exhibiting severe hyperplasia of the mucosa and other microscopic changes, as described. The mechanism of pathogenesis involved three factors: strangulation of the villi, pressure atrophy, and chronic irritation by the crests of the synlophe. In …

Cuticular Ridge Patterns Of Nematodirus (Nematoda: Trichostrongyloidea) Parasitic In Domestic Ruminants Of North America, With A Key To Species, J. R. Lichtenfels, P. A. Pilitt

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The six species of Nematodirus parasitic in domestic ruminants of North America have been identified previously on the basis of characteristics of the bursa and tips of the spicules, and females could not be identified. In an effort to find additional diagnostic characteristics of both sexes, cuticular ridges were studied with light and scanning electron microscopy and in whole mounts and cross sections. After the cuticular ridges of males were characterized, females were matched with males by means of cuticular ridges, except for the rare species N. davtiani. Five of the six species have variations of an 18-ridge bilaterally …

A New Species Of Chronogaster Cobb, 1913 (Nemata : Plectidae) With An Amended Diagnosis Of The Genus And Discussion Of Cuticular Ornamentation, Armand R. Maggenti, Dewey J. Raski, Puthenkandathil K. Koshy, Varghese K. Sosamma

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Chronoguster spinicorpus n. sp. is described from soil about the roots of coconut palm in Kerala, India. It is distinguished from all other species of Chronogaster by its longitudinal rows of spines. The stability of the genus Chronogaster is discussed with stress on internal anatomy and distribution of cephalic sensillae as generic characteristics. Most external ornamentation is judged to be diagnostic for species only.

Nematodirus neotoma Hall, 1916, is redecscribed and N. tortuosus Tucker, 1942, is placed in synonymy with it. Cysticercoids of Paruterina vandelabraria (Goeze, 1782) Fuhrmann, 1906, and immature Monoecocestus sp. constitute new host records.

Pinworms And Primates: A Case Study In Coevolution, Daniel R. Brooks, David R. Glen

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Cladistic analysis of 13 species of Enterobius based on 31 morphological characters supports the notion that pinworms and primates have co-speciated. A possible exception is the relationship between Enterobius vermicularis and Homo. Enterobius vermicularis is postulated to be the sister-species of E. buckleyi + E. lerouxi + E. anthropopitheci. Thus, if co-speciation has occurred, Homo is the sister-group of Pongo + Gorilla + Pan. Examination of the possibility that E. vermicularis in Homo is the result of host-switching or that Homo has been misclassified demonstrates that the latter possibility is the more parsimonious one.

A Simulations Approach To Discerning Possible Sister-Groups Of Dioecotaenia Schmidt, 1969 (Cestoda: Tetraphyllidea: Dioecotaeniidae), Daniel R. Brooks

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Apparent common architectural constraints in the structure of the bothridia of both species of Dioecotaenia permit testing of a number of models for the evolution of the scolex of Dioecotaenia from that found in other tetraphyllidean cestodes. Although presently known species of Dioecotaenia exhibit bothridialloculi in the shape of hexagons, derivation of those bothridia from an ancestor possessing a single central hexagonal bothridium with marginal loculi would not produce total bothridialloculi numbers consistent with those known. A more feasible derivation involves an ancestral form exhibiting three linear loculi. If the loculi are arranged vertically, as in species of Rhinebothrium, …

Hysterothylacium Pelagicum Sp. N. And H. Cornutum (Stossich, 1904) (Nematoda: Anisakidae) From Marine Fishes, Thomas L. Deardorff, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Hysterothylacium pelagicum sp. n. from the digestive tract of the dolphin, Coryphaena hippurus, is described from the Atlantic and Pacific oceans. It is most similar to H. cornutum, but differs from it by lacking ventral crests on the males and having the vulva located within the anterior 30-40% rather than 18-25% of the female body. Specimens of H. cornutum are reported from Thunnus albacares, a previously unrecorded host, off Hawaii.
