Some Platyhelminth Parasites Of Sirens (Amphibia: Sirenidae) From North America, Daniel R. Brooks, Richard L. Buckner

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A new genus and species of digenean and a new species of cestode are described and a previously described species of digenean reported for the first time from Siren intermedia from Illinois. A new genus is proposed for a previously described digenean, and another known species of digenean reported from Siren lacertina in Florida. Progorgodera foliata from S. intermedia has a foliate hind- body characteristic of members of Phyllodistomum and multiple testes arranged in 2 longitudinal rows characteristic of members of Gorgodera. Ophiotaenia sireni from the same host resembles O. filaroides in number of testes, O. amphiumae and O. …

Two Tetraphyllidean Cestodes From The Freshwater Stingray Potamotrygon Magdalenae Dumeril 1852 (Chondrichthyes: Potamotrygonidae) From Colombia, Daniel R. Brooks, Thomas B. Thorson

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Two new tetraphyllidean cestodes are described from the freshwater stingray Potamotrygon magdalenae from Colombia. The new genus Potamotrygonocestus is proposed for P. magdalenensis, which differs from Pedibothrium by having a bilobed rather than X-shaped ovary, and simple rather than bifid hooks. It further differs from Pachybothrium hutsoni by having bothridial hooks inserted immediately posterior to an accessory sucker rather than inserted in the middle of a thick muscular pad. Potamotrygonocestus magdalenensis is unique among known tetraphyllideans by possessing vitellaria which are compact, cylindrical bands in the lateral portions of the middle of the proglottid. The second new species, Rhinebothrium …

Fabespora Vermicola Sp. N., The First Myxosporidan From A Platyhelminth, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The myxosporidan Fabespora vermicola sp. n., tentatively placed in the family Myxidiidae, is described from the digenean Crassicutis archosargi in an estuarine fish. The myxosporidan becomes the first known from a platyhelminth and the third from an invertebrate. It differs from the only other member of the genus primarily by having polar filaments 32 to 44 μm long rather than about 8 μm, and an infection with it can stop reproduction in the digenean host either by physical means or by necrosis of gametes.

A Redescription Of Crassicutis Archosargi, A Digenean Exhibiting An Unusual Tegumental Attachment, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The homalometrine Crassicutis archosargi from the northern Gulf of Mexico is redescribed, and some related digeneans are discussed. Numerous unidentified refractile bodies occurred in the tegument and other tissues of a few specimens of C. archosargi, and an intimate relationship between the parasite and its piscine host resulting from a modified tegument is reported for others. Binding by the described adhesive tegument increases the number of known ways digeneans attach to their hosts. Several specimens also harbored a histozoic myxosporidan in several tissues and a flagellate, Hexamita sp., in their ceca.

A Comparison Of The In Vitro Phagocytic Activity Of Polymorphonuclear Leucocytes And Alveolar Macrophages From Man And Rabbits, Thomas S. Harrison

Biology ETDs

It has been thought for many years that the alveolar macrophage is the primary agent responsible for prevention or bacterial invasion or the lung. Numerous studies with Staphylococcus aureua, Staphylococcus epidermidis, Escherichia coli. Klebsiella, and Proteus have been cited to substantiate this statement. Together these organisms cause less than ten per cent of human bacterial pneumonias. Both in vivo and in vitro studies have shown that the alveolar macrophage is capable of bacterial clearance with time. Sadly lacking ss evidence that alveolar macrophages readily phagocytose Streptococcus pneumoniae which are responsible tor greater than ninety percent of all bacterial pneumonias. The …

Endoparasites Of Cats In Two Central Utah Communities, Thomas W. Sawyer

Theses and Dissertations

A survey of the endoparasites of 100 stray cats in central Utah was conducted. Each cat was euthanized, and the entire alimentary tract, gall bladder, bile duct, heart, respiratory and excretory systems were excised and examined for endoparasites. Fecal samples were examined by a sugar flotation technique. Parasites identified and number of cats infected were: Isospora felis 5; I. rivolta, 4; Dipylidium caninum, 1; Hydatigera taeniaformis, 10; Toxocara mystax, 43; and Physaloptera sp., 2. One ectoparasite, Cheyletiella parasitivorax, was identified in the feces of 4 cats. Dipylidium caninum and T. mystax are known to cause accidental infection in humans and …

Anesthetization Of Morphologically Similar Species With Carbon Dioxide For Separation And Culture, Gregory R. Noel, Armand R. Maggenti

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Nematologists frequently encounter congeneric species in sampling for nematodes. No convenient method for the separation of morphologically similar species has been described. For Meloidogyne spp., inoculum consisting of hundreds of eggs can be easily obtained from a single egg mass and a pure population reared on a suitable host. The separation and culture of other plant parasitic nematode species, such as Paratrichodorus spp., is often more difficult. The species may be separated by placing a single female in the rhizosphere of a host plant, but the chances of a single nematode increasing to a high population in a short time …

A Screening, Referral, And Follow-Up Program For High Blood Pressure At Henry Ford Hospital: Part I. Results Of Screening, Andrea Foote, John C. Erfurt, John R. Caldwell

Henry Ford Hospital Medical Journal

Data are reported on the screening results from the Henry Ford Hospital screening, referral and follow-up program for high blood pressure. The report covers the period of March 27 through December 11, 1975, during which time 808 people were screened in the hospital lobby. Thirty-nine percent were found upon initial screening to have high blood pressure readings or previously diagnosed hypertension. Of these people, 70% were already under treatment for hypertension, but only 21% showed adequate blood pressure control (with readings below 140/90 mm Hg). Those with high readings were referred to their physicians. A paper on the results of …

Susceptibility Of Clinical Isolates Of Bacteria To Cefamandole, Cefoxitin And Cephalothin, R. Del Busto, A. Suarez, E. Quinn, D. Pohlod

Henry Ford Hospital Medical Journal

The in vitro susceptibility was determined of 274 isolates to cephalothin and two new antibiotics, cefamandole and cefoxitin. Cefamandole was comparable to cephalothin in preventing growth of cultures of the gram positive organisms except for penicillin-resistant Staphylococcus aureus which was more sensitive to cephalothin. Cefamandole was more active than cephalothin against all the gram negative bacteria including Haemophilus influenzae and in addition it was active against many strains of Enterobacter sp. Cefoxitin was less active than cephalothin against the gram positive organisms but it was more active against most of the gram negative bacteria. In addition. It was active against …

Concurrent Infection Of Trypanosoma Musculi Kendell, 1906, And Schistosoma Mansoni Sambon, 1907 In Mice, Berhane Andeberhan

Loma Linda University Electronic Theses, Dissertations & Projects

The possible effects of ablastin on Schistosoma mansoni were investigated by (1) establishing a concurrent infection of Trypanosoma musculi and Schistosoma mansoni in mice, and (2) by obtaining Trypanosoma lewisi immune rat serum (ablastin) and injecting it into S. mansoni infected mice. These procedures were followed on days 4, 14 and 28 of S. mansoni infection. For the groups that were given immune rat serum, controls were kept into which normal rat serum was injected.

Ablastin does not have any effect on the development or morphology of the S. mansoni worms as tested in this study. Although ablastin inhibits glycolytic …

Neodeuterobaris Pritchardae Gen. Et Sp. N. (Digenea: Microscaphidiidae) In A Sideneck Turtle, Podocnemis Lewyana Dumeril 1852, From Colombia, Daniel R. Brooks

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Neodeuterobaris pritchardae in the stomach of the freshwater turtle, Podocnemis lewyana, from Colombia resembles members of Deuterobaris in possessing ventral glands, a dorsal oral hood, and vitelline follicles confluent posteriorly, but apparently differs from them by possessing 5 rather than 7 rows of ventral glands; by lacking ventral spines, extracecal uterine loops, and a muscular esophageal bulb; and by inhabiting the stomach of freshwater turtles rather than the intestine of marine turtles. Those characters are considered significant enough to erect a new genus. Diagnosis of the Deuterobaridinae is emended to accommodate the new species.

Five Species Of Platyhelminths From Bufo Marinus L. (Anura: Bufonidae) In Colombia With Descriptions Of Creptotrema Lynchi Sp. N. (Digenea: Allocreadiidae) And Glypthelmins Robustus Sp. N. (Digenea: Macroderoididae), Daniel R. Brooks

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Gorgoderina diaster, Cylindrotaenia americana, and Ophiotaenia bonariensis are reported, and Creptotrema lynchi and Glypthelmins robustus described from Bufo marinus from 3 localities in the Republic of Colombia. All are new locality records and B. marinus is a new host for G. diaster and C. americana. Creptotrema lynchi differs from C. creptotrema in possessing smaller eggs, relatively smaller oral papillae and suckers, and elongate rather than spherical testes. Glypthelmins robustus differs from all other species in the genus in possessing a pharynx which is significantly larger than the acetabulum and tegumental spines restricted to the anterior fifth of …

Parasites Of California Marine And Estuarine Fish, Milton S. Love, Mike Moser

Harold W. Manter Laboratory of Parasitology: Faculty Publications

While working on the parasites of several California marine fish, it was difficult to find out which parasites had been reported from our fish. Pertinent sources were scattered over a number of journals, covering many years. We compiled this list because we felt there was a need for a single source which would give all the parasites infecting California marine fish. As "marine fish" was a somewhat vague term, we decided to use it in a broad sense and included estuarine and anadromous fish in the survey. In addition, we have included records from landlocked populations of anadromous fish, such …

Comparative Properties Of Bacteriophage Φ6 And Φ6 Nucleocapsid, James L. Van Etten, Les Lane, Carlos Gonzalez, James Partridge, Anne Vidaver

Department of Plant Pathology: Faculty Publications

Nonionic detergent treatments released a nucleocapsid from the enveloped bacteriophage φ6. The nucleocapsid sedimented at nearly the same rate as the whole phage in sucrose density gradients, but the buoyant density in Cs₂SO₄ changed from 1.22 g/cm³ for the whole phage to 1.33 g/cm³ for the nucleocapsid. The detergent completely removed the lipid and 5 of the 10 proteins from the phage. Surface labeling of the phage and nucleocapsid with ¹²⁵I revealed that protein P3 was on the outer surface of the whole phage and P8 was on the surface of the nucleocapsid. Both …

Histology Of Apical Tissue : A Comparative Study Of Sargenti Formula, Short Vs. Overfill, James G. Schulze

Loma Linda University Electronic Theses, Dissertations & Projects

Four Stump-tail monkeys (Macaca spiciosa) were used for this study to analyze, on a cellular level, the apical tissue of teeth overfilled versus teeth filled short 1-3 mm. of the radiographic apex with the Sargenti formula. In each animal four incisors were filled short and four incisors were overfilled. A final sample size consisted of 28 teeth. The time periods ranged from 48 hours to 120 days. After analysis of the histology it can be stated that the teeth filled short showed no inflammation to moderate inflammation in the periapical tissues. In teeth overfilled there was a range from moderate …

Determination Of Lead Content In Apical Tissue Following Root Canal Obturation With Sargenti's Formula, G. Merle Hickok

Loma Linda University Electronic Theses, Dissertations & Projects

Four Stump-tail monkeys were used to help determine if the lead in Sargenti's formula diffuses out into the apical tissue while confined entirely within the root canal. In each animal two teeth were filled with Sargenti's formula 1-2 millimeters short of the radiographic apex, and two teeth were filled with gutta percha and Proco-Sol sealer for controls, making a total sample size of sixteen. The time ranged from 48 hours to 120 days. Lead analysis using the spectrophotometric method showed a higher lead content in the teeth filled with Sargenti's formula than with the gutta percha controls.

Prevalence Of Antibodies To Toxoplasma Gondii In Wild And Domestic Animals Of New Mexico, Arizona And Colorado, Alan A, Marchiondo, Donald W. Duszynski, Gary O. Maupin

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Using the Sabin-Feldman dye test, sera from wild and domestic animals in New Mexico, Arizona and Colorado were tested for the prevalence of antibodies to Toxoplasma gondii. The prevalence of positive titers (≥ 1:8) in animals from these areas was: New Mexico (178 of 569, 31%), Arizona (11 of 56, 20%), and Colorado (2 of 7, 29%). The overall prevalence of antibodies to Toxoplasma was 30% (191 of 632).

Nine of 17 fecal samples from wild zoo felines contained Toxoplasma-like oocysts which were inoculated per os and intraperitoneally into mice. Mice from six of these nine inoculations later …

Immunoglobulins Attached To And In The Integument Of Adult Schistosoma Mansoni Sambon 1907, From First Infection Of Cf1 Mice, Franklin Sogandares-Bernal

Harold W. Manter Laboratory of Parasitology: Faculty Publications

7S_γ2b antibody was found attached to and in the integument of adult Schistosoma mansoni removed from CF₁ white mice. With the techniques used, I_gA, I_gM, 7S_γ1, 7S_γ2a, 7S_γ3, and C3 complement were not found to be attached to the integumental surfaces. 7S_γ2b does not seem to fix C3, and it is suggested this antibody may be acting in enhancing and blocking roles which protect the worms from the host.

Mif-Like Activity In Non-Stimulated And Virus-Infected Cell Cultures, Eve Welling Brown

MUSC Theses and Dissertations

Macrophage migration inhibition factor (MIF) is a lymphocyte-derived substance which plays an important role in cell mediated immunity. Soluble factors containing MIF-like activity and produced by non-stimulated and virus-infected non-lymphoid cells have also been reported. In the present study, a MIF-like factor was repeatedly detected in Buffalo green monkey kidney cells infected with mumps or herpes simplex virus (HSV) indicating that this substance is reproducible and can be stimulated by a RNA and a DNA virus. Wistar-38 (WI-38) cell cultures also increased production of this substance in response to mumps but not HSV infection, indicating that the production of this …

The Arthropod Ectosymbionts Of The Fox Squirrel In Coles County, Illinois, Jeanine L. Stanis

Masters Theses

The body surface areas of 18 squirrels (Sciurus niger) were calculated by regions, and the numbers and densities of the ectoparasite populations present on each region determined. Four species representing four genera of arthropods were recovered. The louse, Neohaematopinus antennatus was the most abundant organism with Orchopeas howardii, Haemagamasus reidi, and Dermacentor variabilis being also present. The average population density of all parasite species combined was highest on the back and decreased on the belly, tail, legs, and the head respectively. Body regions showing greatest average total population densities were different for males and females. The …

Blood Parasites Of Illinois Wild Turkeys, Ulrike G. Guenthner

Masters Theses

Blood smears, from 152 wild turkeys (Meleagris gallopavo silvestris) killed during hunting seasons in southern Illinois, were examined for blood parasites. Haemoproteus meleagridis infected 34% of the 83 adult and 19% of the 69 immature turkeys. Of the infected birds, 54% had one or two infected cells per 5000 erythrocytes and 78% had one to five. Infection rates were significantly higher in counties along the Mississippi River than in Pope County, located about 40 miles east of the river. Other parasites specifically searched for but not found were Leucocytozoon, Plasmodium, Trypanosoma and microfilaria.

Efficacy Of Bunamidine Hydrochloride Against Immature And Mature Stages Of Echinococcus Granulosus, Lauritz A. Jensen

Theses and Dissertations

A study was conducted to determine the efficacy of bunamidine hydrochloride against the immature and mature stages of Echinococcus granulosus found in Utah. Twenty-seven dogs were obtained from local animal shelters and experimentally infected with the parasite. The drug was given at dosage levels of 25 mg/kg to 50 mg/kg of bodyweight. It was from 85.9 to 98.8% effective against the immature stage, and 100% effective against the adult stage. The results suggest that this drug can feasibly be used under field conditions where hydatid disease is endemic.

A. chelydrae, A. parvus, and A. louisianaensis are considered valid species. New host records for A. chelydrae are Bufo americanus, Rana catesbeiana, Chrysemys picta, and Graptemys pseudogeographica.

Prevalence Of Toxoplasma Antibodies In Range Vs. Dairy Cattle From The Bitterroot Valley Of Montana, Franklin Sogandares-Bernal, A. A. Marchiondo, Donald W. Duszynski, J. K. Ward

Harold W. Manter Laboratory of Parasitology: Faculty Publications

"Natural" or unaltered foods have become a fad in recent years. This includes the drinking of unpasteurized cow's milk as well as that designated "Certified." This report is made to call attention to a high prevalence of antibodies to toxoplasma in dairy as compared with range cattle. Previous to this study, few papers have considered the breed or conditions of management of cattle sampled for toxoplasma antibodies (McIlwain, 1969, Arch Environ Health 19: 885-886; Vanderwagen et aI., 1974, J Am Vet Med Assoc 164: 1,034-1,037).

Bacterial Endocarditis And Incarceration Of A Transvenous Pacemaker: Removal Under Cardiopulmonary By-Pass After Prolonged Traction Proved Ineffective, Remigio Garcia, Mehdi Hakimi-Naini

Henry Ford Hospital Medical Journal

Transvenous electrode endocardial pacing of the right ventricle is the most simple and common modality of permanent pacing at present. The incidence of endocarditis is rare. Only two patients were found in our hospital series of over 200 who had permanent transvenous pacemakers implanted. A 40-year-old housewife developed staphylococcus aureus endocarditis secondary to local wound infection in the power pack pocket, requiring removal of the infected electrode under cardiopulmonary by-pass. Prolonged traction of the retained electrode proved ineffective. The mechanism of electrode entrapment is discussed.
