Agar Plate Culture Of Selected Trypanosomatidae, Amy Doran Keppel

School of Biological Sciences: Dissertations, Theses, and Student Research

Summary

The study of trypanosomatid biology would benefit greatly from the acquisition of a tool for culturing such as those used in microbiology. Agar plate culture has been described several times, but until the present its potential for use in this area has been underestimated. The previous work has demonstrated that this culture method may be used to culture a wide variety of species, that these species give rise to identifiable colony phenotypes, and that these are stable regardless of the life cycle stage used to initiate the culture. It was also shown that colonies could be initiated from the …

Alveolar Hydatid Disease In Minnesota: First Human Case Acquired In The Contiguous United States, William G. Gamble, Martin Segal, Peter M. Schantz, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A 56-year-old woman from southwestern Minnesota underwent an extended left hepatic lobectomy to remove a large multinodular mass with a necrotic central cavity. The clinical, serological, and pathological findings led to the diagnosis of alveolar hydatid disease, and specific identification of Echinococcus multilocularis was achieved by growing mature larvas in voles inoculated intraperitoneally with tissue from the hepatic lesions. The patient probably acquired her infection some years previously from pet cats or dogs that had become infected by ingesting infected rodents. In North America E. multilocularis is enzootic in the northern tundra zone of Alaska and Canada. Since 1964 the …

Scanning And Transmission Electron Microscopy Of The Oocyst Wall Of Isospora Lacazei, Clarence A. Speer, Alan A. Marchiondo, Bodo Mueller, Donald W. Duszynski

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The oocyst wall of Isospora lacazei from sparrows was studied with scanning (SEM) and transmission (TEM) electron microscopy. In TEM, t he oocyst wall consisted of four distinct layers (Ll-4). The innermost layer, Ll, was moderately electron-lucent and 240-285 nm thick; L2 was electronJense and 210-240 nm thick; L3 was moderately electron-lucent and 15-150 nm thick; L4, the outer most layer, was discontinuous and consisted of electron-dense discoid bodies which measured 180-220 nm x 320-840 nm. The discoid bodies of L4 as seen by TEM appeared spheroid in shape when observed by SEM. One or two membranes were situated on …

Paravitellotrema Overstreeti Sp. N. (Digenea: Hemiuridae) From The Colombian Freshwater Stingray Potamotrygon Magdalenae Dumeri, Daniel R. Brooks, Monte A. Mayers, Thomas B. Thorson

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Paravitellotrema overstreeti from the freshwater stingray Potamotrygon magdalenae in northern Colombia most closely resembles P. thorsoni by possessing a muscular sinus organ and sinus sac as well as exhibiting a saccate rather than elongate prostatic vesicle, It differs by possessing lobate rather than spherical vitellaria, a smaller sinus organ and sinus sac, elongate rather than diamond-shaped prostatic cells enclosed in a delicate membrane rather than free in the parenchyma, and a metraterm joining the hermaphroditic duct immediately anterior to the prostatic vesicle rather than at the base of the sinus organ,

Differentiation Of Fourth And Early Fifth Stages Of Parascaris Equorum (Goeze, 1782) Nematoda: Ascaridoidea, P. A. Pilitt, J. R. Lichtenfels, P. A. Madden

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The morphology of Parascaris equorum of horses was studied; light and scanning electron microscopy were used. Late fourth-stage larvae have narrow, rectangular lips bearing few, large . triangular, irregularly spaced denticles and the lips are not markedly set off from the body. The cuticle of the late fourth stage is completely transversely striated, with incomplete longitudinal ridges creating a brickwork pattern; longitudinal alae are present. Total body lengths of fourth-stage larvae range from 10 to 32 mm. A single molting fourth-stage male was found to be 33 mm long. Early fifthstage nematodes have wide, trilobate lips with a deep transverse …

The Role Of Cuticular Strata Nomenclature In The Systematics Of Nemata, Armand R. Maggenti

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A system of cuticular nomenclature based on the strata observed in Enoplia is proposed. Nematode cuticle is divided into four fundamental strata: epicuticle, exocuticle, mesocuticle, and endocuticle. Application of this system allows the correlation of complementary strata throughout Nemata. The major taxonomic categories within Nemata are differentiated on the basis of their cuticular strata as compared with the Enoplia model cuticle.

Endoparasites, John E. Ubelaker, Robert D. Specian, Donald W. Duszynski

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The leaf-nosed bats of the New World family Phyllostomatidae occur from the southwestern United States through tropical Central and South America. Members of this family are also found throughout the Antilles. The ecological associations of the species in this family seem to be rather broad; species are found in humid tropical to semiarid and arid subtropical environments. Diversity in feeding is readily apparent ranging from nectivores (Glossophaga), frugivores (Artibeus), sanguivores (Desmodus), to omnivores (Phyllostomus) (see review by Glass, 1970; Gardner, this volume).

To understand better the biology of phyllostomatid bats, it is …

Neopronocephalus Orientalis Sp. N. (Digenea: Pronocephalidae) And Spirhapalum Elongatum Rohde, Lee, And Lim, 1968 (Digenea: Spirorchiidae) From Cuora Amboinensis (Daudin) In Malaysia, Daniel R. Brooks, James R. Palmieri

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Neopronocephalus orientalis from Cuora amboinensis in Malaysia most closely resembles N. spinometraterminis from Kachuga tectum tentoria in India by possessing postovarian cecal tips and an average of more than 30 vitelline follicles, but differs by having equatorial rather than preequatorial testes which are mostly intercecal rather than extracecal and a slightly smaller cirrus sac, Neopronocephaius spinometraterminis purportedly has spines in the metraterm and a common genital pore, whereas N . orientalis exhibits nonstaining wrinkled epithelium lining the metraterm and separate genital pores. Spirhapalum elongatum was also collected from its type host near the type locality.

New Records For Amphibian And Reptile Trematodes, Daniel R. Brooks

Harold W. Manter Laboratory of Parasitology: Faculty Publications

From 1975 to 1978, 200 amphibians and reptiles from localities in Nebraska, Arkansas, Oklahoma, Louisiana, Mississippi, Florida, North Carolina, and West Virginia were examined for trematode parasites. This report provides additional information concerning the geographical distribution of North American amphibian and reptile trematodes. Some results have already been published (Brooks and Fusco, 1978, J. Miss. Acad. Sci. 23:95-99). Worms, removed from their hosts, were examined alive when possible, and fixed with AFA after flattening with slight coverslip pressure. Specimens were stored in 7{)1lO ethanol, then stained with Mayer's hematoxylin and mounted in Histoclad or Canada balsam for study as whole …

Oligacanthorhynchus Lamasi (Freitas And Costa, 1964) Comb. N. From Domestic Cats Of Brazil, J. F.R. Amato, Brent B. Nickol, O. M. Froes

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Freitas and Costa (1964, Arq. Esc. Vet. Univ. Fed. Minas Gerais 16:231-234) described a new species, Echinopardalis lamasi, from two acanthocephalans (1 male, 1 female) of a cat, Felis domestica (=F. catus), captured in Belo Horizonte, Minas Gerais. These specimens have been lost (Freitas, 1975, personal communication). Until two of 127 domestic cats, F. catus, from Porto Alegre, Rio Grande do SuI, captured between October 1973 and July 1976, were found to harbor respectively two and nine acanthocephalans conspecific with those described by Freitas and Costa, no additional specimens of this species were available for study. These new specimens assist …

A Filamentous Bacterium On The Brine Shrimp And Its Control, Mobashir A. Solangi, Robin M. Overstreet, Ann L. Gannam

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A strain of a colorless, filamentous bacterium (tentatively identified as Leucothrix mucor) heavily infests the brine shrimp, Artemia salina. Its ultrastructure, unlike that of some other strains, does not reveal a distinct middle layer between its outer cell wall layer and cytoplasmic membrane, irregular blebs extending from the cell layers, or an external sheath. An entire infestation, represented as a mat of the bacterium with associated debris and microorganisms, sloughs from the shrimp when exposed to a variety of treatments. Primarily because most effective treatments are toxic to the shrimp, 100 ppm terramycin provides the treatment of choice.

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Two new species of Acanthobothrium are reported from freshwater stingrays in northern South America. Acanthobothrium quinonesi sp. n. is described from Potamotrygon magdalenae Dumeril collected from the Magdalena River in northern Colombia and A. amazonensis sp. n. from P. circularis Garman collected in the Itacuai River of northwestern Brazil. Acanthobothrium quinonesi differs from A. amazonensis by having a smaller and anteriorly-curved cirrus sac, 43-60 rather than 50-72 testes, and bothridial hooks 100-142 μm long rather than 145-184 μm long. Characters used in the taxonomy of Acanthobothrium species are listed to show that the new species resemble each other and A. …

Experimental Transmission Of Sarcocystis From Icterid Birds To Sparrows And Canaries By Sporocysts From The Opossum, Edith D. Box, Donald W. Duszynski

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Cowbirds (Molothrus ater) and grackles (Cassidix mexicanus) infected with muscle cysts of Sarcocystis were fed to opposums (Didelphis virginiana) and fecal sporocysts from the latter were given to sparrows (Passer domesticus, Family Ploceidae), canaries (Serinus canarius, Family Fringillidae) and ducks (Anas platyrhynchos, Family Anatidae). Asexual parasites were found in the endothelium of sparrows and canaries but not in ducks. When birds were kept 10 weeks or more after infection, muscle cysts were found grossly and microscopically in the majority of sparrows, and in 1 canary, but not in …

Acanthobothrium Electricolum Sp. N. And A. Lintoni Goldstein, Henson, And Schlicht 1969 (Cestoda: Tetraphyllidea) From Narcine Brasiliensis (Olfers) (Chondrichthyes: Torpedinidae) In Colombia, Daniel R. Brooks, Monte A. Mayes

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Acanthobothrium lintoni and a new species of Acanthobothrium are reported from the lesser electric ray Narcine brasiliensis in Colombia. The new species resembles all other members of the genus parasitizing torpedinids by having a relatively small scolex, long and spinose cephalic peduncle, fewer than 75 testes per proglottid, an indistinct genital atrium, and V-shaped ovaries with ovarian lobes of equal length which do not reach the posterior margin of the cirrus sac. The new species differs from all known species by having bothridial hooks only 46 to 64 μm in total length. A key to the species of Acanthobothrium parasitizing …

Adult Cestodes From The Coelomic Cavity Of The Teid Lizard, Cnemidophorus Sexlineatus, Wesley L. Shoop, John J. Janovy Jr.

John J. Janovy, Jr. Publications

In a survey of 64 Cnemidophorus sexlineatus, adult cestodes identified as Oochoristica bivitellobata with gravid proglottids were found in the coelomic cavity of two hand caught specimens at Cedar Point Biological Station, Ogallala, Nebraska, during June and July 1977. Two O. bivitellobata were found free in the coelom of a male lizard, whereas four were found in the coelom and one in the intestine of a female. No ruptures were found in the walls of the intestines of all lizards examined. In addition, 61 O. bivitellobata were found in the intestine of nine (14%) of the C. sexlineatus with …

Spirocamallanus Cricotus Sp. N. And S. Halitrophus Sp. N. (Nematoda: Camallanidea) From Fishes In The Northern Gulf Of Mexico, Alan C. Fusco, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Spirocamallanus cricotus sp. n. (= S. pereirai, in part) and S. halitrophus sp. n. are described from marine fishes of the northern Gull of Mexico. Spirocamallanus cricotus has a ledge anterior to the basal ring in the buccal capsule, similar spicules with a ratio of 1:1.4 to 2.1, 3 pre- and 5 postcloacal papillae, and 8 rectal glands in the female; S. halitrophus lacks the ledge and possesses dissimilar spicules with a ratio of 1:1.3 to 1.8, 3 pre- and 6 postcloacal papillae, and 4 rectal glands in the female.

The Opossum (Didelphis Virginiana) As A Host For Sarcocystis Debonei From Cowbirds (Molothrus Ater) And Grackles (Cassidix Mexicanus, Quiscalus Quiscula), Donald Duszynski, Edith D. Box

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Sarcocystis-infected muscles from ducks, cowbirds, and grackles were fed to cats, opossums, rats, and a dog. Only the opossum (Didelphis virginiana) was a suitable definitive host. All opossums that were fed Sarcocystis-infected cowbirds (Molothrus ater) and grackles (Cassidix mexicanus and Quiscalus quiscula) passed sporocysts in their feces. Opossums that ate the cowbirds had prepatent periods of 5 and 10 days and remained patent for at least 105 days. Opossums that ate the grackles became patent on day 10 after the infective meal and remained patent for over 90 (Quiscalus) and …

Implication Of An Environmentally Induced Hamartoma In Commercial Shrimps, Robin M. Overstreet, Thomas Van Devender

Harold W. Manter Laboratory of Parasitology: Faculty Publications

An overgrowth of muscle protruded through the ventral portion of the sixth abdominal segment of Penaeus aztecus and P. setiferus. This hamartoma was observed in 33 postlarval shrimp and is the first reported from a crustacean. Even though afflicted individuals represented a small proportion of the shrimp examined, nearly all such individuals were collected from the presumed most heavily polluted site. We suggest an unidentified pollutant as the cause of the abnormality.

Permanent Light Microscopy Slides Of Eimeria Nieschulzi Oocysts, Alan A. Marchiondo, Donald W. Duszynski

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The methods described here allow for the preparation of light microscopy slides of coccidian oocysts and thus, provide a durable sample and record for research and teaching. These methods used only one species, Eimeria nieschulzi; however, it is likely that use of other coccidian oocysts would produce similar results.

Food Of The Red Drum, Sciaenops Ocellata, From Mississippi Sound, Robin M. Overstreet, Richard W. Heard

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Examined digestive tracts of the red drum in Mississippi Sound contained mostly decapod crustaceans. Crustaceans accounted for 34 of 59 encountered taxa, more than reported from any other region. Nevertheless, the general diet for 104 fish with food contents out of the 107 examined is similar to that reported for red drum in several other studies from other areas. In addition to crustaceans, fishes followed by polychaetes occurred as the most important items (in 99, 43, and 15% of the drum with food, respectively). Blue crabs occurred in even more drum than the frequently encountered penaeid shrimps. Other commercial species …

Suppressed Rejection Of Trichinella Spiralis In Immunized Rats Concurrently Infected With Eimeria Nieschulzi, Donald W. Duszynski, Deborah Russell, Shirley A. Roy, Gilbert A. Castro

Harold W. Manter Laboratory of Parasitology: Faculty Publications

This study deals with the effect of Eimeria nieschulzi infection on the host immune response to Trichinella spiralis. Six male Sprague-Dawley rats were inoculated with 10⁴ and six with 10⁶; sporulated E. nieschulzi oocysts. On days 2, 8, and 16 post-inoculation (PI), two rats from each infected group, and their paired uninfected controls, were killed and mucosal scrapings from their small intestines were assayed for peroxidase activity. Peroxidase levels were higher than corresponding control values on days 2 and 16 PI and significantly lower than the controls on day 8 PI. These data led us to …

Prehistoric Cremations From Nogales, Arizona *, Karl J. Reinhard, Jeff H. Shipman

Karl Reinhard Publications

In October, 1969, the Highway Salvage Section of the Arizona State Museum conducted emergency salvage excavations in conjunction with the construction of the Tucson-Nogales Highway. Ten cremations were recovered from a backhoe trench which had been placed within the city limits of Nogales, Arizona. Analysis of the cremations indicated cultural contact between the Trincheras culture of Sonora, Mexico, and the Hohokam culture of the Santa Cruz River Valley in southern Arizona.

Food Of The Atlantic Croaker, Micropogonias Undulatus, From Mississippi Sound And The Gulf Of Mexico, Robin M. Overstreet, Richard W. Heard

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The diet of the Atlantic croaker from Mississippi Sound has been examined for the first time. Over 83 taxa were encountered, or more than were reported from croaker in any other region. We also found 60 taxa, 36 of which overlapped with the above, in croaker from various offshore stations in the Gulf of Mexico. In Mississippi Sound the frequency of occurrcnce of items revealed primarily crustaceans followed by polychaetes, molluscs, fishes, and less common items, and, in the open Gulf, molluscs appeared slightly more often than in inshore croaker and than polychaetes in offshore fish. The diets were assessed …

Poecilancistrium Caryophyllum And Other Trypanorhynch Cestode Plerocercoids From The Musculature Of Cynoscion Nebulosus And Other Sciaenid Fishes In The Gulf Of Mexico, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Examination of over 3,000 fish, all sciaenids, has shown that plerocercoids of Poecilancistrium caryophyllum infect Cynoscion nebulosus, Bairdiella chrysura, Sciaenops ocellata, C. arenarius, Micropogonias undulatus, and Pogonias cromis in Mississippi Sound. In addition to P. caryophyllum, a pseudophyllidean-like trypanorhynch also infected C. nebulosus and M. undulatus. Pseudogrillotia pleistacantha selectively infected large P. cromis, Pterobothrium heteracanthum infected M. undulatus, and Pterobothrium lintoni infected Menticirrhus americanus. Prevalence and intensity of infections of P. caryophyllum in C. nebulosus from Mississippi, roughly 40% of the fish each possessing an average of about two worms, …
