Breeding And Use Of Nonhuman Primates In The Usa, Joe R. Held

Experimentation Collection

Several species of nonhuman primates, each possessing specific characteristics of particular value, are used by the United States biomedical community in a wide variety of health-related activities. These animals are man's closest relatives and are indispensable in the effort to understand and control human health problems.

The destruction of primate habitats and embargoes on export of primates from source countries have decreased the supply of these animals. Continuation of many ongoing and new activities contributing to the improvement of human health is threatened by inadequate and erratic supply of these resources. In the U.S., a program has been developed to …

Equine Behavior Problems In Relation To Humane Management, Katherine A. Houpt

Equines Collection

The behavior problems of horses are frequently related to management practices. Behaviors that are termed stall vices appear to be either stereotyped behaviors that occur in reaction to stress, or patterns that emerge when natural behaviors such as grazing are prevented. The behavior cases presented to the New York State College of Veterinary Medicine, Cornell University, were tabulated: 27% were stall vices and 27% were some form of aggression. The stall vices were circling, digging, kicking the stall, chewing wood, swallowing air or self-mutilation. Management of horses on pasture rather than in stalls prevents the development of many of these …

Composition And Dynamics Of The Plasma Membrane Of Entamoeba Histolytica, Stephen Blaine Aley

Student Theses and Dissertations

The study of the parasitic protozoa presents a multifaceted opportunity for biological research. These organisms are eucaryotic cells with many of the biological systems described in higher eucaryotic cells. However, they are adapted to highly specialized environments, invoking sometimes subtle and often unique variations of these biological systems. More important, an understanding of the biology of the parasite and the differences between the parasite and mammalian cells can be invaluable in the development of pharmacological and immunological methods of control of the parasite. The subject of this thesis, the parasitic amoeba Entamoeba hystolytica, is an ideal subject for such research. …

Effects Of Purified Salmonella Enteritidis Endotoxin On The Immune Response Of Balb/C Mice, John B. Barnett, John W. Jutila

Journal of the Arkansas Academy of Science

Wasting disease was produced in neonatal Balb/c mice with purified Salmonella enteritidis endotoxins. The endotoxins were chemically characterized to provide the study with a potent endotoxin with constant biological activity. Neonatal mice received an initial injection of 35 μg/g body weight of endotoxin and a dose of 75 μg every third day until day 18. The degree of wasting was estimated by the runting (weight loss) index. Mortality was calculated to be 46%, with a mean survival time of approximately 15 days. The hematologic studies conducted at days 10, 20, and 30 showed an absolute neutrophilia and leukocytosis by day …

Parasites And Diseases Of Mullets (Mugilidae), I. Paperna, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The following treatment of parasites, diseases and conditions affecting mullet hopefully serves several functions. It acquaints someone involved in rearing mullets with problems he can face and topics he should investigate. We cannot go into extensive illustrative detail on every species or group, but do provide a listing of most parasites reported or known from mullet and some pertinent general information on them. Because of these enumerations, the paper should also act as a review for anyone interested in mullet parasites or the use of such parasites as indicators about a mullet's diet and migratory behavior. Unfortunately, limited space prohibits …

Differentiation Of Late Fourth And Early Fifth Stages Of Ascaris Suum Goeze, 1782 (Nematoda: Ascaridoidea) In Swine, P. A. Pilitt, J. Ralph Lichtenfels, F. G. Tromba, P. A. Madden

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The morphology of late fourth and early fifth stages of Ascaris suum in swine was studied with light and scanning electron microscopy. Late fourth-stage larvae have dome-shaped lips, that are broadest at the base and incompletely separated laterally. The lips bear coarse, triangular dentides, irregularly spaced on the internomedial and internolateral walls. Large double papillae are located on the middle of the external lip surface. The cervical region gradually increases in width posteriorly. The late fourth-stage cuticle is marked by a coarse transverse striation and bears incomplete longitudinal ridges, creating a brickwork pattern; longitudinal alae are present. Late fourth and …

Two New Tetraphyllidean Cestodes From Potamotrygon Circularis Garman (Chondrichthyes: Potamotrygonidae) In The Itacnai River, Brazill, Monte A. Mayes, Daniel R. Brooks, Thomas B. Thorson

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The new genus Rhinebothroides is proposed to include three species of Rhinebothriumlike cestodes parasitizing freshwater stingrays in South America. They differ from Rhinebothrium species by having squared rather than elongate bothridia, by possessing internal seminal vesicles, and by exhibiting terminal genitalia at the ovarian level. Rhinebothroides circularisi sp. n. in Potamotrygon circularis from the Itacuai River in northwestern Brazil differs from R. moralarai by having more testes and bothridial loculi and differs from R. scorzai by lacking vitelline follicles proximate to the genital pore, by having a straight rather than coiled vagina, and by possessing craspedote rather than acraspedote …

Stress: What Is It And How Can It Be Quantified?, T. H. Friend

International Journal for the Study of Animal Problems

An animal may be considered to be in a state of stress if abnormal behavior or extreme adjustments in its behavior or physiology are necessary in order to cope with adverse aspects of its environment. Methods used to determine if an animal is stressed can be either behavioral or physiological. Behavioral methods may be highly erroneous due to their subjective nature since alterations in behavior do not necessarily prove that an animal is stressed. There is no single measure of stress that can be used in all situations at this time. Every measure must be critically evaluated to ensure that …

Problems With Kosher Slaughter, Temple Grandin

International Journal for the Study of Animal Problems

Ritual slaughter to produce kosher meat is rooted in the teachings and writings of the Talmud. However, the preslaughter handling features of modern systems, particularly the shackling and hoisting of large steers, contravene the basic message of humaneness included in the teachings. The throat-cutting of a live, conscious animal is relatively pain-free, provided that certain precautions are followed, but U.S. kosher plants need to install newly developed conveyor-restrainer systems to eliminate the abuses of shackling and hoisting. Conveyor-restrainer systems for large and small animals are discussed.

Morphology Of Leishmania Donovani Colonies Grown On Blood Agar Plates, Amy Doran Keppel, John J. Janovy Jr.

John J. Janovy, Jr. Publications

Previous studies have shown that several species of Trypanosomatidae can be grown as discrete and, in some cases clonal, colonies on blood agar plates, and that species differ in colony phenotype (Noeller, 1917, Arch. Schiffs Trop. Hyg. 21: 5-94; Senekjie, 1944, J. Parasitol. 30: 303-308; Newton, 1956, Nature 177: 279-280; Keppel and Janovy, 1977, J. Parasitol. 63: 879-882). None of these previous studies, however, has addressed the following question: Does the life cycle stage used to initiate agar plate culture affect colony phenotype? The question also can be phrased as follows: Does passage through a vertebrate host alter agar plate …

Myxosoma Funduli Kudo 1918 (Protozoa: Myxosporida) In Fundulus Kansae (Pisces: Cyprinodontidae): Annual Prevalence And Geographic Distribution, Stephen A. Knight, John J. Janovy Jr., William L. Current

John J. Janovy, Jr. Publications

The occurrence and distribution of the myxosporidan, Myxosoma funduli, in the Plains killifish (Fundulus kansae) were investigated. Samples from sites on the South Platte and Platte River drainages in Nebraska were collected by seining during various months of 1976, 1977, and 1978. At a number of the localities no F. kansae were found; the remainder of the collecting sites showed the host population to be abundant, but the M. funduli infections to vary in prevalence. The protozoan parasite population in F. kansae, upstream from the Nebraska Tri-County Diversion Dam and Canal, at North Platte, Nebraska, demonstrated …

Recurrent Klebsiella Meningitis Following Trans-Sphenoidal Hypophysectomy For Nelson's Syndrome: Chloramphenicol Resistance During Relapse, Tom Madhavan, Daria Kiani, Louis Saravolatz, Keith Burch, Raymond C. Mellinger

Henry Ford Hospital Medical Journal

Three episodes of meningitis due to Klebsiella pneumoniae occurred in a young man following cerebral surgery. The patient had the features of Nelson's syndrome, and a chromophobe adenoma was removed by trans-sphenoidal resection. Intravenous chloramphenicol was effective in producing a temporary clinical response during the first episode of meningitis, but the organism became resistant to chloramphenicol during the second episode. Combined parenteral and intralumbar administration of gentamicin resulted in temporary improvement only. Subsequently, the subcutaneous cerebrospinal fluid (CSF) reservoir of Ommaya provided a safe, convenient way to administer prolonged intraventricular therapy which, combined with a definitive procedure to correct the …

Biology And Pathogenesis Of The Coccidium Eimeria Funduli Infecting Killifishes, Mobashir A. Solangi, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Epizootics of Eimeria funduli involved estuarine killifishes (Fundulus grandis, F. pulvereus, F. similis, and F. heteroclitus) in Mississippi, Alabama, and Virginia. All of more than 500 specimens examined of F. grandis from Mississippi during 1977 through 1979 had infections, regardless of age, sex, or season collected. Oocysts occurred primarily in the liver and pancreas, replacing up to 85% of both those organs. Infrequent sites of infection were fatty tissue of the body cavity, ovary, intestine, and caudal peduncle. Living fish did not discharge oocysts. Eimeria funduli is the first known eimerian to require a second host. To …

Effects Of Ddt Upon The Hematology And Immunology Of The Goldfish (Carassius Auratus), Maurice G. Zeeman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

DDT can cause hematological and immunological alterations in mammals and birds. Interference with normal hematological and immunological defense systems has been strongly linked to increased incidences of disease and tumors. Fish exposed to pesticides have been noted to be more susceptible to disease. This study examined DDT effects on goldfish hematological and immunological parameters.

Adult goldfish were kept in 250 liter aquaria at 25 ± 1° C. Fish were dosed intraperitoneally with p,p'-DDT in corn oil. Doses ranged from 0 to 500 mg/kg for acute (96 hour) hematology studies to 0 to 50 mg/kg for sub-acute hematology and immunology studies. …

Skin Lesions Associated With E. Coli Sepsis In A Patient With Acute Leukemia, Robert A. Chapman, Ellis J. Van Slyck, Tom Madhavan

Henry Ford Hospital Medical Journal

The clinical course of a patient with acute leukemia and metastatic intradermal abscesses secondary to Escherichia coli sepsis is described. E. coli organisms, cultured first from the blood and later from the lesions, had an identical antibiotic susceptibility and biotyping profile. This complication has not been previously described. Granulocytopenia and varicose veins may have been critical predisposing factors. With more widespread use of progressive immunosuppressive regimens, unusual manifestations of common infections will be recognized more frequently.

Semiconservative Synthesis Of Single-Stranded Rna By Bacteriophage Φ6 Rna Polymerase, James L. Van Etten, Dwight E. Burbank, Diane A. Cuppels, Leslie C. Lane, Anne K. Vidaver

Department of Plant Pathology: Faculty Publications

The RNA polymerase in the nucleocapsid of seudomonas phaseolicola bacteriophage φ6 transcribed large, medium, and small single-stranded RNA from the viral double-stranded RNA genome by a semiconservative (displacement) mechanism. Approximately 23%, 63%, and 65% of the nucleocapsid particles in the assay mixture synthesized at least one round of large, medium, and small single-stranded RNA molecules, respectively. Some of these particles reinitiated synthesis such that an average of 1.5 large, 33 medium, and 24 small singlestranded RNAs were synthesized from each double-stranded RNA.
