The Toxoplasma Gondii Cyst Wall Protein Cst1 Is Critical For Cyst Wall Integrity And Promotes Bradyzoite Persistence, Tadakimi Tomita, David J. Bzik, Yan Fen Ma, Barbara A. Fox
Dartmouth Scholarship
Toxoplasma gondii infects up to one third of the world's population. A key to the success of T. gondii as a parasite is its ability to persist for the life of its host as bradyzoites within tissue cysts. The glycosylated cyst wall is the key structural feature that facilitates persistence and oral transmission of this parasite. Because most of the antibodies and reagents that recognize the cyst wall recognize carbohydrates, identification of the components of the cyst wall has been technically challenging. We have identified CST1 (TGME49_064660) as a 250 kDa SRS (SAG1 related sequence) domain protein with a large …

Archaic mummies from northern Chile were examined for the presence of Pediculus humanus capitis. The excellent preservation of mummies and louse nits/eggs permitted a study of the degree of head lice infestation. We studied 63 Chinchorro mummies (ca. 5000–3000 years B.P.) from the Arica-Camarones coast. An area of 2 cm × 2 cm on each mummy’s head was systematically inspected for louse nits/eggs. Hairs with nits/eggs and lice were collected and analyzed using optic and scanning electronic microscopy. About 79% (50/63) of the mummies resulted positive for pediculosis, with an average of 2.1 nits/ eggs/cm2 per positive individual. Microscopic …

Sucking lice (Phthiraptera: Anoplura) are obligate blood-feeding ectoparasites of placental mammals including humans. Worldwide, more than 550 species have been described and many are specific to a particular host species of mammal. Three taxa uniquely parasitize humans: the head louse, body louse, and crab (pubic) louse. The body louse, in particular, has epidemiological importance because it is a vector of the causative agents of three important human diseases: epidemic typhus, trench fever, and louse-borne relapsing fever. Since the advent of antibiotics and more effective body louse control measures in the 1940s, these diseases have markedly diminished in incidence. However, due …
Schistosomiasis (Bilharzia) In Madagascar: A Case Study Of A Neglected Tropical Disease, Sarah Grace Sawyer
Schistosomiasis (Bilharzia) In Madagascar: A Case Study Of A Neglected Tropical Disease, Sarah Grace Sawyer
Independent Study Project (ISP) Collection
Over 50% of Madagascar’s population is infected with intestinal or urinary schistosomiasis (Rollinson et al., 2012). The disease slowly debilitates infected persons, who are frequently children, resulting in lower productivity and reduced learning in school-age children. The disease involves a vicious cycle perpetuated by a number of environmental, psychological, and social factors. A multifaceted approach, involving mass treatment, biological control, environmental control, education, and disease surveillance, can lead to schistosomiasis control and elimination in Madagascar. This would yield many socio-economic benefits such as increased productivity, increased school attendance rates, and generally better welfare. Schistosomiasis is the most burdensome and deadly …

We undertook the analysis of Zweeloo Woman, a bog mummy from the Netherlands, to assess her parasitic state. Evidence of infection came from two areas: (1) liver paraffin sections and (2) microfossils washed from an intestinal section. Although the liver had shrunken considerably, objects consistent with operculated trematode eggs were found. After evaluating the range of trematode species that produce eggs in liver tissue, we arrived at the diagnosis of Dicrocoelium dendriticum. Although only 0.1 ml of sediment was recovered from an intestinal section, eggs of Ascaris lumbricoides and Trichuris trichiura were also identified. No eggs of D. dendriticum were …

An Insight Into The Microbial Diversity And Expression Of Cysteine Protease Inhibitors (Cystatin) In Rickettsia Parkeri Infected Amblyomma Maculatum, Khemraj Budachetri
Master's Theses
Amblyomma maculatum (Gulf Coast tick) is an emerging tick species of public health significance in United States. It is a competent vector of Rickettsia parkeri, an etiological agent of a human rickettsiosis. In this study, we investigated the spotted fever group of rickettsial diversity in A. maculatum based on rickettsial ompA gene PCR. Our results showed A. maculatum harbors R. parkeri, R. amblyommii, and R. endosymbiont of A. maculatum. While only R. parkeri was detected in female salivary glands which suggest its ability to traffic from midgut to salivary glands via hemocoel. The presence of R. parkeri was further …

Schistosomiasis japonica is a major parasitic disease threatening millions of people in China. Though overall prevalence was greatly reduced during the second half of the past century, continued persistence in some areas and cases of re-emergence in others remain major concerns. As many regions in China are approaching disease elimination, obtaining quantitative data on Schistosoma japonicum parasites is increasingly difficult. This study examines the distribution of schistosomiasis in eastern China, taking advantage of the fact that the single intermediate host serves as a major transmission bottleneck. Epidemiological, population-genetic and high-resolution ecological data are combined to construct a predictive model capable …

In Vitro Selection Of Chloroquine Tolerant Plasmodium Falciparum Parasites, Daniel A. Daley
Biological Sciences Theses & Dissertations
Malaria is among the most devastating human diseases, and a majority of lethal cases are caused by the protozoan parasite, Plasmodiumfalciparum. The emergence of multi-drug resistant P.falciparum is a major obstacle to malaria control and is highlighted by the abandonment of chloroquine (CQ) as a first-line treatment of P.falciparum infections worldwide. Chloroquine resistance (CQR) is associated primarily with mutations in the transmembrane digestive vacuole protein, PfCRT. However, CQR P.falciparum parasites harboring the same mutant pfcrt allele vary in their CQ response, suggesting the CQ response is multigenic in nature. No gene outside of pfcrt is completely associated with CQR. Thus, …

Approximately 680 million people are at risk of infection with Opisthorchis viverrini (OV) andClonorchis sinensis, with an estimated 10 million infected with OV in Southeast Asia alone. While opisthorchiasis is associated with hepatobiliary pathologies, such as advanced periductal fibrosis (APF) and cholangiocarcinoma (CCA), animal models of OV infection show that immune-complex glomerulonephritis is an important renal pathology that develops simultaneously with hepatobiliary pathologies. A cardinal sign of immune-complex glomerulonephritis is the urinary excretion of immunoglobulin G (IgG) (microproteinuria). In community-based studies in OV endemic areas along the Chi River in northeastern Thailand, we observed that over half of …

Background. The common symptoms of malaria reduce the specificity of clinical diagnosis. Presumptive treatment is conventional but can lead to overdiagnosis of malaria, delay of appropriate treatment, overprescription of antimalarials, and drug resistance. Routine use of diagnostic tests can address many of these concerns. Though treatment is often procured from retailers, there is low availability of rapid diagnostic tests for malaria (MRDTs), a simple, inexpensive, and accurate diagnostic solution. We know little about the challenges to expanding access to diagnostics through these outlets. Methods. To understand the perceptions of the benefits and challenges to selling rapid diagnostic tests for malaria, …

Neglected tropical diseases (NTD) impair physical and cognitive development. This impairment makes it difficult to earn a living, restricts quality of life, and limits productivity in the work force. As a result, neglected tropical diseases trap the poor in a cycle of disease and poverty. Lymphatic filariasis (LF), also known as elephantiasis, is an NTD. It starts when microscopic, thread-like parasitic worms (Wuchereria bancrofti, Brugia timori, and Brugia malayi) are transmitted by mosquitoes. These worms infect and block the lymph nodes in the body, causing edema. Blockage in the lymphatic system and build-up of tissue and blood flow often occur …

Automated Point-Of-Care Image Processing Methodology For The Diagnosis Of Malaria, Michael B. Jorgensen
Master's Theses
Malaria has profoundly influenced human history for over four thousand years and despite numerous attempts at eradication, the prevention, diagnosis, and treatment of malaria have been largely ineffective. More than five hundred million people are affected by malaria every year resulting in over one million deaths. Drug resistance development by the parasite has diminished the effectiveness of numerous treatment options due, in part, to overtreatment of negative patients based on insufficient clinical algorithms and diagnostic methods. The goal of this research was to develop an image analysis algorithm to diagnose malaria with a high degree of sensitivity and specificity in …

Naturally occurring human immunity to both schistosomiasis and hookworm infection has been associated with IgE responses against parasite allergen-like proteins. Since the two helminths frequently coinfect the same individuals, there is growing advocacy for their concurrent treatment. However, both helminths are known to exert strong immunomodulatory effects; therefore, coinfected individuals could have immune responses different from those characteristically seen in monoinfected individuals. In this study, we measured changes in IgE, IgG1, and IgG4 responses to schistosome and hookworm antigens, including the allergen-like proteins Schistosoma mansoni tegumental-allergen-like 1 protein (SmTAL1), SmTAL2, and Necator americanus Ancylostoma-secreted protein-2 (Na-ASP-2), following concurrent …

Treatment for clinical schistosomiasis has relied centrally on the broad spectrum anthelmintic praziquantel; however, there is limited information on its mode of action or the molecular response of the parasite. This paper presents a transcriptional and functional approach to defining the molecular responses of schistosomes to praziquantel. Differential gene expression in Schistosoma japonicum was investigated by transcriptome-wide microarray analysis of adult worms perfused from infected mice after 0.5 to 24 hours after oral administration of sub-lethal doses of praziquantel. Genes up-regulated initially in male parasites were associated with “Tegument/Muscle Repair” and “Lipid/Ion Regulation” functions and were followed by “Drug Resistance” …
