Hookworms are intestinal nematode parasites that infect nearly half a billion people and are globally one of the most important contributors to iron-deficiency anemia. These parasites have significant impacts in developing children, pregnant women and working adults. Of all the soil-transmitted helminths or nematodes (STNs), hookworms are by far the most important, with disease burdens conservatively estimated at four million DALYs (Disability-Adjusted Life Years) and with productivity losses of up to US$139 billion annually. To date, mainly one drug, albendazole is used for hookworm therapy in mass drug administration, which has on average approximately 80% cure rate that is ...


In Vivo And In Vitro Studies Of Cry5b And Nicotinic Acetylcholine Receptor Agonist Anthelmintics Reveal A Powerful And Unique Combination Therapy Against Intestinal Nematode Parasites, Yan Hu, Melanie Miller, Bo Zhang, Thanh-thanh Nguyen, Martin K.

In Vivo And In Vitro Studies Of Cry5b And Nicotinic Acetylcholine Receptor Agonist Anthelmintics Reveal A Powerful And Unique Combination Therapy Against Intestinal Nematode Parasites, Yan Hu, Melanie Miller, Bo Zhang, Thanh-Thanh Nguyen, Martin K. Nielsen, Raffi V. Aroian

Open Access Articles

BACKGROUND: The soil-transmitted nematodes (STNs) or helminths (hookworms, whipworms, large roundworms) infect the intestines of ~1.5 billion of the poorest peoples and are leading causes of morbidity worldwide. Only one class of anthelmintic or anti-nematode drugs, the benzimidazoles, is currently used in mass drug administrations, which is a dangerous situation. New anti-nematode drugs are urgently needed. Bacillus thuringiensis crystal protein Cry5B is a powerful, promising new candidate. Drug combinations, when properly made, are ideal for treating infectious diseases. Although there are some clinical trials using drug combinations against STNs, little quantitative and systemic work has been performed to define ...

BACKGROUND: Blood flukes of the genus Schistosoma cause schistosomiasis-a neglected tropical disease (NTD) that affects more than 200 million people worldwide. Studies of schistosome genomes have improved our understanding of the molecular biology of flatworms, but most of them have focused largely on protein-coding genes. Small non-coding RNAs (sncRNAs) have been explored in selected schistosome species and are suggested to play essential roles in the post-transcriptional regulation of genes, and in modulating flatworm-host interactions. However, genome-wide small RNA data are currently lacking for key schistosomes including Schistosoma haematobium-the causative agent of urogenital schistosomiasis of humans.

METHODOLOGY: MicroRNAs (miRNAs) and other ...

Comparing The Efficacy Of Copper Oxide Wire Particles And Copper Sulfate On Haemonchus Contortus In Goats, James Mackey 2018 Murray State University

Comparing The Efficacy Of Copper Oxide Wire Particles And Copper Sulfate On Haemonchus Contortus In Goats, James Mackey

Honors College Theses

This is a comparative study on the anthelmintic effects of copper oxide wire particles (COWP), copper sulfate (CuSO4), and Levamisole on Haemonchus contortus in goats. This study was designed to compare the efficiency of COWP and CuSO4 at controlling H. contortus populations in goats. A study group of 60 female goats was randomly separated into 3 groups. The does in each group were administered either a copper sulfate drench by weight, a Levamisole drench by weight, or a 4g bolus of COWP. Fecal egg counts and Faffa Malan Charts (FAMACHA), were performed every 2 weeks, and Packed Cell ...

Can Prescribed Fire Reduce Tick Parasitism Of Birds?, Leslie A. Sterling, Kim Medley, Katie Westby, Solný Adalsteinsson

Undergraduate Research Symposium Posters

Tick-borne diseases spread through enzootic transmission cycles that often involve ticks parasitizing bird hosts. Some avian species are competent reservoirs, amplifying the pathogens that cause tick-borne illnesses in humans. Prescribed burns in forests have the potential to reduce tick-borne disease risk if they limit interactions between ticks and infectious wildlife hosts. Although prescribed burns are increasingly being used for a variety of habitat management purposes, little is known about how they affect tick-host interactions. We hypothesize that if prescribed fires reduce tick abundance, then birds in burned forest plots will host fewer ticks than birds in unburned forest plots. Experimental ...

The type 2 immune response is the central mechanism of disease progression in schistosomiasis, but the signals that induce it after infection remain elusive. Aberrant microRNA (miRNA) expression is a hallmark of human diseases including schistosomiasis, and targeting the deregulated miRNA can mitigate disease outcomes. Here, we demonstrate that efficient and sustained elevation of miR-203-3p in liver tissues, using the highly hepatotropic recombinant adeno-associated virus serotype 8 (rAAV8), protects mice against lethal schistosome infection by alleviating hepatic fibrosis. We show that miR-203-3p targets interleukin-33 (IL-33), an inducer of type 2 immunity, in hepatic stellate cells to regulate the expansion and ...

Visceral leishmaniasis (VL) is a major public health issue reported as the second illness in mortality among all tropical diseases. Clinical trials have shown that protection against VL is associated with robust T cell responses, especially those producing IFN-gamma. The Leishmania amastigote 2 (A2) protein has been repeatedly described as immunogenic and protective against VL in different animal models; it is recognized by human T cells, and it is also commercially available in a vaccine formulation containing saponin against canine VL. Moving toward a more appropriate formulation for human vaccination, here, we tested a new optimized version of the recombinant ...


A Rare Case Of Enhancing Anterior Interhemispheric Racemose Neurocysticercosis With Foci Of Calcification And Direct Parenchymal Extension, Anupama Chandrappa, Rajesh Raman, Suchetha Satish 2018 JSS Medical College Hospital, JSS University, Mysore

A Rare Case Of Enhancing Anterior Interhemispheric Racemose Neurocysticercosis With Foci Of Calcification And Direct Parenchymal Extension, Anupama Chandrappa, Rajesh Raman, Suchetha Satish

Journal of Global Radiology

Neurocysticercosis (NCC) refers to the central nervous system (CNS) infestation of the larvae of pork tapeworm Taenia solium. It is endemic in Central and South America, Asia and Africa. It most commonly presents as intraparenchymal subcentimetric ring enhancing lesions of variable ages (or size and duration) with surrounding vasogenic edema. The lesions calcify with time. Rarely, NCC can occur in extraparenchymal locations, within the subarachnoid space and ventricles. At these locations it is usually seen as a proliferative lobulated cystic mass without a scolex which is termed racemose neurocysticercosis. Racemose cysticerci do not show calcification, scolex, or enhancement.

Drug Repurposing For Schistosomiasis: Combinations Of Drugs Or Biomolecules., Maria João Gouveia, Paul J Brindley, Fátima Gärtner, José M Correia da Costa, Nuno Vale 2018 George Washington University

Drug Repurposing For Schistosomiasis: Combinations Of Drugs Or Biomolecules., Maria João Gouveia, Paul J Brindley, Fátima Gärtner, José M Correia Da Costa, Nuno Vale

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Schistosomiasis is a major neglected tropical disease. Control of schistosomiasis currently relies on a single drug, praziquantel, and despite its efficacy against the all schistosome species that parasitize humans, it displays some problematic drawbacks and alone is ineffective in counteracting adverse pathologies associated with infection. Moreover, due to the development of the potential emergence of PZQ-resistant strains, the search for additional or alternative antischistosomal drugs have become a public health priority. The current drug discovery for schistosomiasis has been slow and uninspiring. By contrast, repurposing of existing approved drugs may offer a safe, rapid and cost-effective alternative. Combined treatment with ...

Open Access Articles

BACKGROUND: Proper collection and storage of fecal samples is necessary to guarantee the subsequent reliability of DNA-based soil-transmitted helminth diagnostic procedures. Previous research has examined various methods to preserve fecal samples for subsequent microscopic analysis or for subsequent determination of overall DNA yields obtained following DNA extraction. However, only limited research has focused on the preservation of soil-transmitted helminth DNA in stool samples stored at ambient temperature or maintained in a cold chain for extended periods of time.

METHODOLOGY: Quantitative real-time PCR was used in this study as a measure of the effectiveness of seven commercially available products to preserve ...

Parasitic helminths infect over 1 billion people worldwide, while current treatments rely on a limited arsenal of drugs. To expedite drug discovery, we screened a small-molecule library of compounds with histories of use in human clinical trials for anthelmintic activity against the soil nematode Caenorhabditis elegans. From this screen, we found that the neuromodulatory drugs sertraline, paroxetine, and chlorpromazine kill C. elegans at multiple life stages including embryos, developing larvae and gravid adults. These drugs act rapidly to inhibit C. elegans feeding within minutes of exposure. Sertraline, paroxetine, and chlorpromazine also decrease motility of adult Trichuris muris whipworms, prevent hatching ...

Comoros: Malaria, Elizabeth Rennolds

Global Public Health

After human settlement and migration took place throughout the world, a disease known as malaria broke out within many countries. Malaria is a disease that comes from a fever where a parasite takes over one’s red blood cells with mosquitoes being the ones that transmit this disease. The symptoms of this disease are as follows: fever (typical cycles of fever, chills, sweating), joint pain, headaches, vomiting, convulsions, and coma. Malaria is a big issue in the Comoros, an island which can be seen in the Indian Ocean between the eastern coast of Africa and Madagascar, because of the many ...

Chikungunya: India, Allison Harvey

Global Issues in Public Health

A communicable disease is an infectious disease, transmissible by direct contact with an affected individual or the individual’s discharges, or by indirect means. The more direct contact people have, the more disease spreads explaining why larger populations have more outbreaks of communicable diseases. India, in particular, has one of the biggest population sizes and makes them susceptible to those diseases. Many can be fatal. However, other diseases, such as chikungunya, are also dangerous viruses that put specific populations at risk for health problems if infected. With chikungunya symptoms such as fever or rashes may develop. Some symptoms such as ...
