Pigeon Associated People Diseases, Walter Weber

Bird Control Seminars Proceedings

Feral pigeons (Columbia livia) are not harmless birds. Many potential infections of humans silently exist in pigeons which are not apparent. They have the potential for transmission of over 30 diseases to humans plus another ten to domestic animals. Environmental pollution from pigeon droppings is quite evident. Air pollution involves more than noxious gases from automobile exhausts and belching smokestacks. One serious air pollutant is air-borne fungi, which are agents for infectious diseases. There is much information written about the problem, but it remains primarily in the professional journals and technical references, neatly stacked away on library shelves. …

A New And Unusual Eimerian (Protozoa: Eimeriidae) From The Liver Of The Gulf Killifish, Fundulus Grandis, Donald W. Duszynski, Mobashir A. Solangi, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Oocysts and sporocysts of Eimeria funduli sp. n. are described from the Gulf killifish, Fundulus grandis, on the basis of light microscopy, transmission and scanning electron microscopy, and location in the liver of infected hosts. The spherical sporulated oocysts of E. funduli isolated from liver tissue measure 20-31(25) μm across with ovoid sporocysts 9-11 × 5-7 (10 × 6) μm. A micropyle, polar granule, and oocyst residuum are absent, but sporocysts have Stieda and substieda bodies, a few residual granules, and 10-25 (15) unique projecting structures with expanded distal portions that we term “sporopodia.” Sporopodia 1-3 (2) μm high …

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 …

Humanities In Medical Education- The Past Ten Years, James J. Quinn

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

What has always fascinated me is an historical account that ends triumphantly but whose start-to-finish is riddled with reversals and hostile obstacles and haunted by anguishing circumstances. The history of "humanities in medical education- the past ten years" in the United States is just such a story. In the last ten years there has been a continually wider acceptance of humanities in United States medical schools, i.e., a growing number of schools introducing the humanities, a growth in the quality and scope of programs being offered, and a greater acceptance of the humanities as an integral part of the medical …

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 …

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 …

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 cutick 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 groove …

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,

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.

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.

Two New Species Of Acanthobothrium Van Beneden 1849 (Cestoidea: Tetraphyllidea) From Freshwater Stingrays In South America, Monte A. Mayes, Daniel R. Brooks, Thomas B. Thorson

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

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 …
