Background: Zinc supplementation in young children has been associated with reductions in the incidence and severity of diarrheal diseases, acute respiratory infections, and malaria.

Objective: The objective was to evaluate the potential role of zinc as an adjunct in the treatment of acute, uncomplicated falciparum malaria; a multicenter, double-blind, randomized placebo-controlled clinical trial was undertaken.

Design: Children (n = 1087) aged 6 mo to 5 y were enrolled at sites in Ecuador, Ghana, Tanzania, Uganda, and Zambia. Children with fever and ≥ 2000 asexual forms of Plasmodium falciparum/μL in a thick blood smear received chloroquine and were randomly assigned to …

Detection Of Giardia Duodenalis Antigen In Coprolites Using A Commercially Available Enzyme-Linked Immunosorbent Assay, Marcelo Luiz Carvalho Gonçalves, Adauto Araújo, Rosemere Duarte, Joaquim Pereira Da Silva, Karl Reinhard, Françoise Bouchet, Luis Fernando Ferreira

Karl Reinhard Publications

The objective of this experiment was to assess the utility of a commercially available enzyme-linked immunosorbent assay (ELISA) kit for diagnosis of giardiasis in archaeological human remains. The kit, a monoclonal antibody assay, is used to detect the presence of Giardia-specific antigen 65 (GSA65) in human feces. We utilized the assay in ancient fecal material. The material included desiccated feces found in mummies or in archaeological sites, and sediments from latrines. A total of 83 specimens, previously examined microscopically for parasites, were examined. The ELISA detected 3 positive samples, dated to about 1200 AD, 1600 AD, and 1700 AD. …

Multidisciplinary Coprolite Analysis, Karl Reinhard, Dennis R. Danielson, Mark Daniels, Sérgio Augusto De Miranda Chaves

Karl Reinhard Publications

Coprolite analysis, as reviewed by Reinhard and Bryant (1992), contributes unique and detailed information regarding diet and parasitic disease. We present here an analysis of dietary components of coprolites from Bighorn Cave using macroscopic remains, pollen concentrations, and phytoliths. In addition, we analyzed Bighorn Cave coprolites for evidence of parasitic organisms, especially intestinal worms. Such analyses of coprolites have become important methods for reconstructing past dietary and medicinal practices. Pollen concentration and phytolith quantification techniques have recently been developed, but until this report no known attempt has been made to synthesize pollen, macroscopic, and phytolith data from a single coprolite …

Recommended Terminology And Advances In The Systematics Of The Cyathostominea (Nematoda: Strongyloidea) Of Horses, J. Ralph Lichtenfels, L. M. Gibbons, R. C. Krecek

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Terminology for common names for the Tribe Cyathostominea (cyathostomins), and disease caused by the nematodes (cyathostominosis), were recommended to replace the previously used names cyathostomes and cyathostomosis, which are ambiguous, inaccurate or synonymous, by the Third Internal Workshop on the Systematics of Cyathostominea of Horses, held in Stresa, Italy, 28 August 2001. The progress by this international working group at three workshops is reviewed briefly and a list of publications is provided. Included are an annotated checklist by genus and species of 93 species level names and the recognition of 52 species, redescriptions of seven species, and the description of …

A Preliminary Analysis Of Proteolytic Activity Of Excretory-Secretory Products From Cyathostominea, Jane L. Kinsella, J. Ralph Lichtenfels, Michael F. Ryan

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The excretory-secretory product (ESP) derived from Cyathostominea in vitro was assessed, in terms of subunit composition, and proteolytic activity using as substrates azocasein and two synthetic fluorogenic peptides. Sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) resolved 13 subunits, and the presence of the protein cysteine proteinase activator dithiothreitol (DTT) revealed 21 subunits.DTTalso enhanced azocaseinolysis, and hydrolysis of carbobenzoxy-phenylalanyl-arginine-7-amido-4-methylcoumarin (Z-Phe-Arg-NHMec) and carbobenzoxy-arginyl-arginine-7-amido-4-methylcoumarin (Z-Arg-Arg-NHMec). At the optimum pH of 5.5, hydrolysis of Z-Phe-Arg-NHMec was three-fold greater than that of Z-Arg-Arg-NHMec suggesting that the proteolytic specificities of the ESP are more like those of papain or cathepsin L, rather than cathepsin B. In SDS-PAGE …

Identification And Characterisation Of A Cdna Sequence Encoding A Glutamic Acid-Rich Protein Specifically Transcribed In Trichinella Spiralis Newborn Larvae And Recognised By Infected Swine Serum, Dante S. Zarlenga, Patricia Boyd, J. Ralph Lichtenfels, Dolores Hill, H. Ray Gamble

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Presently, little is known of the mechanism by which Trichinella penetrates and modulates reprogramming of muscle cells. In light of evidence demonstrating strong protective characteristics of antigens derived from this stage, understanding this process may shed light on potential targets for effective abatement of infection. To this end, a PCR-derived cDNA expression library was constructed using 0.5 mg of total RNA from Trichinella spiralis newborn larvae. The library consisted of >125,000 insert-containing clones. Approximately 40-50 × 10³ clones were screened immunologically using sera from pigs experimentally infected with 7,000 Trichinella L1. Multiple clones reacting positively with the swine infection …

Foundations For An Integrative Parasitology: Collections, Archives, And Biodiversity Informatics, Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Burgeoning awareness about biodiversity emphasizes the fundamental importance of museum collections and the contributions of systematists and taxonomists in documenting the structure and history of the biosphere. An essential role is served by this infrastructure in collecting, preparing, analyzing, and disseminating information about the specimens that represent species, document a range of complex biological associations from symbioses to parasitism, and form the tapestry and the myriad facets of biodiversity (e.g., Wilson, 2000). As parasitologists we can examine how we may contribute to this broader documentation and understanding of global biodiversity, and we can articulate and communicate our role as vital …

Protostrongylus Stilesi (Nematoda: Protostrongylidae): Ecological Isolation And Putative Host-Switching Between Dall’S Sheep And Muskoxen In A Contact Zone, Eric P. Hoberg, Susan J. Kutz, John Nagy, Emily Jenkins, Brett Elkin, Marsha Branigan, Dorothy Cooley

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The occurrence of Protostrongylus stilesi in a population of introduced muskoxen, Ovibos moschatus wardi, on the Arctic Coastal Plain, Yukon Territory (YT) and Northwest Territories (NT), Canada, is consistent with a contemporary colonization event from Dall’s sheep, Ovis dalli dalli, which indicates that host specificity may be ecologically based and contextual for this parasite. Colonization of muskoxen by P. stilesi may be a predictable event in zones of sympatry with Dall’s sheep; exposure to infection may coincide with occupation of winter ranges of Dall’s sheep by muskoxen during the summer season. Disruption of contemporary ecological isolating barriers can …

Coccidia (Apicomplexa: Eimeriidae) Of The Mammalian Order Chiroptera, Donald W. Duszynski

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The coccidia are protists (phylum Apicomplexa) that, likely, are both the most abundant (numbers of individual zoites) and most speciose of all the kinds of parasites found in/on mammals. They also are among the least studied and understood, with the exception of those species that cause pathology in domesticated Artiodactyla. In this review, I focus only on the largest family of the phylum, Eimeriidae Minchin, 1903, because its members often are among the most prevalent apicomplexans of mammals, and because there has never been a taxonomic summation for those species that infect Chirpotera. In all published descriptions of bat coccidia, …

Ultrastructure Of Tuzetia Weidneri Sp. N. (Microsporidia: Tuzetiidae) In Skeletal Muscle Of Litopenaeus Setiferus And Farfantepenaeus Aztecus (Crustacea: Decapoda) And New Data On Perezia Nelsoni (Microsporidia: Pereziidae) In L. Setiferus, Elizabeth U. Canning, Alan Curry, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A new microsporidian species, Tuzetia weidneri sp. n. , is described from the skeletal muscle of the decapod crustaceans Litopenaeus setiferus and Farfantepenaeus aztecus. Fresh spores are pyriform, measuring 3.1 x 2.3 µm. All stages have unpaired nuclei. Meronts lie in direct contact with degenerate host cell cytoplasm but produce numerous small blisters at the surface. Multinucleate meronts divide by constriction into groups or chains of uninucleate products. Sporogony is initiated by deposition of a dense surface coat on the plasma membrane of uninucleate or multinucleate stages and fusion of blisters to enclose the sporont in a sporophorous vesicle …

The Structure Of The Nucleus Of Odonaticola Polyhamatus (Gregarinea: Actinocephalidae), A Parasite Of Mnais Strigata (Hagen) (Odonata: Calopterygidae), Kasumi Hoshide, John J. Janovy Jr.

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The nucleus of Odonaticola polyhamatus was isolated from the body and observed with light, scanning electron and transmission electron microscopy. The nucleus had a thick thread-like structure with which it was tied to the septum. This thread-like structure has not been reported or described previously. The gregarine nuclear surface was covered with a fine fibrous net. This is the first report of the surface structure of a gregarine nucleus as revealed by SEM. Inside the nuclear membrane was a thin honeycomb layer similar to that reported for some other gregarines. Several spherical nucleoli and numerous electron dense small structures were …

Potential Pathological Effects Of Blood Flukes (Digenea: Sanguinicolidae) On Pen-Reared Marine Fishes, Stephen A. Bullard, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Sanguinicolids, or fish blood flukes, infect the vascular system of both marine and freshwater fishes, and some act as serious pathogens of hosts in aquaculture. Blood flukes typically possess a relatively benign relationship with wild fishes; however, cultured hosts near appropriate intermediate hosts (i.e., snail, bivalve, or polychaete) may accumulate heavy infections of the worms and their eggs. The resulting disease, sanguinicoliasis, has caused mass mortalities of fish reared in ponds and cages in North America, Europe, and Asia. In the life cycle, the cercaria emerges from the intermediate invertebrate host and penetrates into and matures in the definitive fish …

Hydrobiid Snails (Mollusca: Gastropoda: Rissooidea) From St. Andrew Bay, Florida, Richard W. Heard, Robin M. Overstreet, John M. Foster

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Heleobops sp. of Hershler and Thompson appears to be the only previously published record for the gastropod family Hydrobiidae Troschel in tidal waters of the St. Andrew Bay System, Florida. Six species occurred in bayous, marshes, and brackish ponds associated with the System during studies conducted between 1984 and 1999: Texadina barretti (Morrison), Texadina sphinctostoma Abbott and Ladd, Littoridinops monroensis (Frauenfeld), Littoridinops palustris Thompson, Onobops jacksoni (Bartsch), and Heleobops sp. A. The last is an apparently undescribed species closely related to Heleobops carrikeri Davis and McKee. Based in part on this study, Heleobops sp. A, which occurs in brackish habitats …

Internet -Based Education In Egypt: A Pilot Project To Assess Public Health Capacity And The Potential For Distance Education Using A Randomized Controlled Comparison Of An Internet-Based Distance Education Course And A Traditional Face-To-Face Course, Rebecca Ann Noel

All ETDs from UAB

To develop a well-trained global work force, public health workers must take advantage of new opportunities to provide public health training and education. Distance education delivered via the Internet holds particular promise, especially for public health workers in developing countries. Because of the need to travel to the United States, Europe, or elsewhere, public health workers in developing countries have limited access to traditional public health training and education. Even short-courses are not cost-effective or efficient in terms of time and travel. If public health distance education delivered via the Internet could be shown to be equivalent to traditional public …

An Evaluation Study On Nutrition Rehabilitation Centers In Accra, Ghana, Esi Komeley Colecraft

All ETDs from UAB

The primary goals of nutrition rehabilitation centers (NRCs) are to recuperate malnourished children and improve caretakers' child feeding practices. Children ( N = 116) and caretakers ( N = 108) newly enrolled in four NRCs in Accra, Ghana were recruited and studied longitudinally at four time points: admission, interim, exit and postexit . Data collection included observations of activities at the NRCs, anthropometry, interviews, dietary assessments, and weighing of NRC foods. Caretaker/child pairs attended the NRCs 33% ± 21% of their total stay, and the majority (78%) discontinued participation before being officially discharged. At exit , ≥60% of children had …

Towards A Canadian Policy For Patenting Disease Genes, S. Jodi Gallagher

Dalhousie Journal of Legal Studies

Thousands of human genes, many associated with human disease processes and diagnosis, have been patented in Canada. The scope of these patents has restricted public access to genetic testing and raised the question of whether human genetic material should be subject to differential treatment by our patent law regime. The Canadian Intellectual Property Office (CIPO) has failed to offer guidelines on the application of patent laws to genetic material, symptomatic of the broader problem of a lack of strong federal leadership in this area. In this paper I will engage the debate over patenting of human genes specifically as it …

Preliminary Results From A Survey On The Prevalence Of Parasitic Helminths And Protozoa In Raccoons, Opossums, And Skunks, Michelle Belviy, T. A. Yazwinski, C. A. Tucker, Jennifer Robins

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Raccoons, skunks, and opossums (N=57, 60, and 60, respectively) were necropsied for parasite detection and identification from September, 2001 until April, 2002. Qualitative coprological exams and adult Baylisascaris collections have been completed. Fecal stages and/or types found were Baylisascaris and Strongyloides-type (skunks and raccoons); Capillaria and Trichostrongyletype (raccoons and opossums); Acanthacephalan and ascarid type (opossums only); free larvae (skunks only); and coccidial (protozoan) oocysts (all three host species). Adult Baylisascaris were recovered from 33.3% of the raccoons and 58.3% of the skunks. Data collection relative to this survey, which is still ongoing, includes the determination of Sarcocystis prevalence in excised …

Undeserving Addicts: Ssi/Ssd And The Penalties Of Poverty, Dean Spade

Faculty Articles

Since the late 1980's, American media and politicians have produced and participated in a moral panic around the issue of illegal drug use. This panic has generated vivid pictures in the American imagination of drug users as a morally depraved, irresponsible, and willfully criminal underclass. Such images have fueled the "war on drugs," a multi-faceted rhetoric and policy approach to drug use that focuses on incarceration, interdiction, and other criminal justice strategies. The punitive approach of the war on drugs has bled into poverty and disability policy with alarming persistence. The trend has influenced numerous poverty alleviation and disability programs …

Lack Of Benefit Of Granulocyte Macrophage Or Granulocyte Colony Stimulating Factor In Patients With Febrile Neutropenia, T. Siddiqui, I. A. Burney, A. Salam, G. N. Kakepoto, Mohammad Khurshid, R. A. Smego

Section of Haematology/Oncology

Objectives: To compare the clinical benefits of granulocyte-colony stimulating factor (G-CSF) or granulocyte macrophage-colony stimulating factor (GM-CSF) plus standard supportive care to supportive care alone among cancer patients with febrile neutropenia.
Methods: Clinical data were collected retrospectively from 148 consecutive cancer patients with neutropenia and fever. Patients had hematologic (i.e., acute leukemias or lymphoproliferative disorders) or non-hematologic malignancies (i.e., solid tumors including carcinoma of breast, lung, or colon). Clinical variables analyzed included: age and sex; underlying malignancies; chemotherapy regimens; symptoms at time of presentation; duration of fever prior to study enrollment; days from chemotherapy until administration of GM-CSF or …

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Diabetes mellitus increases the rate of vaginal colonization and infection with Candida species

Methods

We surveyed women with diabetes receiving care at either an urban or suburban diabetes clinic to examine the relationship between vaginal Candida colonization, diabetes type and duration, and HbA_1c level. 101 participants completed the self-administered questionnaire and self-collected a vaginal swab for Candida culture. Candida colonization was similar by age and race.

Results

Type 1 diabetics were three times as likely as type 2 diabetics to be colonized with any Candida species (OR = 3.4; 95% CI: 1.03, 11.41; p = 0.04); even …
