Résumé :

The purpose of the present study was to evaluate the potential usefulness of tubulin inhibitors when complexed with hydroxypropyl-beta-cyclodextrin (HP-beta-CD) against a range of protozoan parasites. This approach involved investigations into the complexation of these drugs with HP-beta-CD, and subsequent investigations of these drugs and their complexes in regard to cytotoxicity, pharmacokinetics, in vitro efficacy against Giardia, Cryptosporidium and rodent malaria (Plasmodium chabaudi), and their in vivo efficacy against Giardia and malaria. Albendazole (ABZ) is a benzimidazole carbamat

Résumé :

Protozoan infections such as Malaria, Leishmaniasis, Toxoplasmosis, Chaga’s disease and African trypanosomiasis caused by the Plasmodium, Leishmania, Toxoplasma and Trypanosoma genuses respectively; inflict a huge economic, health and social impact in endemic regions particularly tropical and sub-tropical regions. The combined infections are estimated at over a billion annually and approximately 1.1 million deaths annually. The global burden of the protozoan infections is worsened by the increased drug resistance, toxicity and the relatively high cost of treatment and prophylaxis. Therefore th

Résumé :

Human African Trypanosomiasis (HAT) is an infectious, vector-borne protozoal disease which is amongst the so-called neglected diseases. In 2000, at a summit of the United Nations, eight Millennium Development Goals (MDGs) were set, to be achieved by 2015. MDG 6 states “to combat HIV/AIDS, malaria & other diseases”. With just under 2 years to go before the end of 2015, HAT is still thriving in developing countries. The drugs currently used for the treatment of HAT are in short supply, have severe side effects and those used to treat late stages of the disease are very difficult to administer. T

Résumé :

Equine protozoal myeloencephalitis (EPM), caused by the protozoan parasite Sarcocystis neurona, is one of the most important neurological diseases of horses in the Americas. While seroprevalence of S. neurona in horses is high, clinical manifestation of EPM occurs in less than 1% of infected horses. Factors governing the occurrence and severity of EPM are largely unknown, although horse immunity might play an important role in clinical outcome. We hypothesize that EPM occurs due to an aberrant immune response, which will be discernable in the equine IgG subisotypes a, b, and (T) that recognize

Résumé :

The withdrawal of water sources concluded the reuse of treated wastewaters, especially for non-potable purposes. Agricultural use of the reclaimed wastewaters is one of the reuse options. However health considerations of the reuse of reclaimed wastewaters for public related purposes are underestimated, since wastewaters contain a variety of microbial pathogens, which may be transmitted to workers and consumers through the crops irrigated. Of these, parasitic eggs have a special place, as they are capable of surviving in the soil for months or even years, depending on environmental conditions.

Equine protozoal myeloencephalitis (EPM), predominantly caused by the protozoa Saracocystis neurona, is a common neurologic disease in horses from North America. Equine exposure to the parasite occurs frequently as the protozoa is excreted in opossum (Didelphis virginiana) feces and contaminates the horse's environment. However, clinical neurologic disease only emerges in a small fraction of exposed horses. The seemingly protective immune response that develops in some exposed horses but not all is not fully defined. Previous reports utilizing horse EPM models and immune compromised mouse mode

Résumé :

Sarcocystis neurona is a protozoan parasite that causes the serious neurologic disease equine protozoal myeloencephalitis (EPM). The life cycle of S. neurona progresses through multiple developmental stages that differ morphologically and molecularly. The S. neurona merozoite surface is covered by multiple related proteins, which are orthologous to the surface antigen (SAG) gene family of Toxoplasma gondii. The SAG surface antigens in T. gondii and another related parasite Neospora caninum are life cycle stage-specific and seem necessary for parasite transmission and persistence of infection.

Résumé :

The protozoan parasite Cryptosporidium is now widely accepted as a cause of human gastroenteritis. The apparent lack of host specificity and the ability of the organism to undergo its entire life-cycle within the one host has important epidemiological implications. Studies here in Australia and in many other countries have shown Cryptosporidium to be an important pathogenic agent in gastroenteritis with an increased incidence in children, a strong rural connection and a possible seasonal trend in some places. The results of this study show that there are simple and sensitive methods

DESIGN, SYNTHESIS AND BIOLOGICAL EVALUATION OF NOVEL PSEUDOPEPTIDES AS INHIBITORS OF RHODESAIN OF T. brucei rhodesiense Human African Trypanosomiasis (HAT) is caused by a protozoan of Trypanosoma genus. There are two forms of HAT, the chronic form caused by Trypanosoma brucei gambiense and the acute form caused by Trypanosoma brucei rhodesiense. This infection is transmitted to humans by the bite of a fly belonging to Glossina genus (tsetse fly). There is an urgent need to find new targets for HAT treatment because current therapy shows many problems. In this research area, rhodesain, a cyst

Cells invest a lot of energy in order to get their proteins to fold correctly and attain functionality. It is the functional proteome of a cell that defines the ‘life of a cell’. Cells have therefore employed dedicated machinery called chaperones to enable protein folding. One class of these chaperones is heat shock proteins named so because they were initially discovered to be heat inducible and particularly important during heat stress. However the role of heat shock proteins has now been extended from merely being important for stress tolerance. Heat shock proteins are prominently involved

Résumé :

Giardia lamblia, an enteric protozoan parasite, infects a large number of individuals worldwide. In South Africa prevalences ranging between 4 and 63% are documented, however, the impact of giardiasis is underreseached in this country. Giardia infections vary from asymptomatic carriage or a self-limiting acute symptomatic illness to chronic, debilitating malabsorption syndrome. The factors responsible for development of symptomatic versus asymptomatic infection are poorly understood. It is believed by some that host factors determine the clinical outcome of infection. On the other hand, the po

Résumé :

M.Sc.<br>Research into blood protozoans (haematozoans) infecting African tortoises is scanty with only a few records published, many during the early part of the last century. Little research had been done on the blood parasites of tortoises examined in this study namely, Kinixys lobatsiana, K. belliana belliana, K. natalensis, Geochelone pardalis pardalis, G. pardalis babcocki and Chersina angulata. The study therefore aimed to: 1) examine apicomplexan haematozoan parasites infecting several of South Africa’s indigenous tortoises and compare them with published species descriptions, especiall

Indiana University-Purdue University Indianapolis (IUPUI)<br>Toxoplasma gondii, a single-celled eukaryotic pathogen, has infected one-third of the world’s population and is the causative agent of toxoplasmosis. The disease primarily affects immunocompromised individuals such as AIDS, cancer, and transplant patients. The parasites can infect any nucleated cell in warm-blooded vertebrates, but because they preferentially target CNS, heart, and ocular tissue, manifestations of infection often include encephalitis, myocarditis, and a host of neurological and ocular disorders. Toxoplasma can also b

PfHsp70-1 is distinct in that it possesses glycine-glycine-methionine-proline (GGMP) tetrapeptide repeats in its C-terminal domain. To date, the GGMP motif of PfHsp70-1 has not been studied. The motif is positioned within the C-terminal lid segment of PfHsp70-1. The motif is also about seven residues upstream the terminal EEVD residues that are responsible for the interaction of PfHsp70-1 with its functional regula

Résumé :

MSc (Biochemistry)<br>Department of Biochemistry<br>Sustaining proteostasis is essential for the survival of the cell and altered protein regulation leads to many cellular pathologies. Heat shock proteins (Hsps) are involved in the regulation of the protein quality control. Hsps are a group of molecular chaperones that are upregulated in response to cell stress and some are produced constitutively. The Hsp70 family also known as DnaK in Escherichia coli (E. coli) is the most well-known group of molecular chaperones. Structurally, Hsp70s consist of a nucleotide binding domain (NBD) and a substr

Résumé :

MSc (Biochemistry)<br>Department of Biochemistry<br>Malaria is a disease that claims about half a million lives annually, mainly children. There are 5 Plasmodium species that cause malaria; namely, P. falciparum, P. ovale, P. malariae, P. knowlesi and P. vivax. P. falciparum is the most virulent of them all. The parasite upregulates some heat shock proteins (Hsps) in response to stress it encounters during its life cycle. These Hsps play a major role in proteostasis. The drug resistance of P. falciparum to traditionally used remedies has led to a need for the development of novel drugs. Hsps h
