Liver fluke development: a target for parasite control?
… a debilitating disease caused by flatworm parasites belonging to the genus Fasciola, is a prominent threat to global food security due to its widespread infection of agriculturally significant ruminants. Recent studies have identified a population of proliferative cells within Fasciola …

Functional Education of Monocytes During Infection
… gastrointestinal infection with the protozoan parasite Toxoplasma gondii, recruited monocytes not only contributed to parasite control, but also regulated pathologic immune responses to commensal microbes via secretion of the lipid mediator prostaglandin E2 (PGE2). Priming of monocytes for …

A molecular characterization of agonists that bind to Hco-UNC-49, a GABA-gated chloride channel from Haemonchus contortus
… economic cost. The ability to pharmaceutically control infection has been challenged by the rapid development and spread of drug resistance. The discovery of new targets is therefore required for sustainable parasite control. UNC-49 is a nematode ligand-gated ion channel that plays an important …

Characterizing Peripheral Cellular and Humoral Immune Responses to Haemonchus contortus in Sheep
… prompted exploration of alternative methods of parasite control. Many studies have shown St. Croix hair sheep posses an immunologically mediated resistance to H. contortus infection, however no studies have utilized a true parasite naive animal for immune characterization. In this study, …

The Effects of Naturally Occurring Plant Products on Experimental Haemonchus contortus Infection in Gerbils and Sheep
… has created a need for alternative methods of parasite control. One method involves using plant products with natural anthelmintic properties. This thesis assessed the efficacy of several plant products against experimental Haemonchus contortus infection in gerbils and sheep. In gerbil assays, …

Veterinary Therapeutic and Biologic Agents in Virginia Sheep Production
… a median of 1.5 treatments per sheep per month. Parasite control and vaccination were the most frequent reasons for treatment (64.9% and 15.2%, respectively) with vitamin/mineral supplementation being the next most common (8.8%). Price information was collected for 13,912 treatment events. An …

Sex-influenced histopathological changes and the immunity during Toxoplasma gondii infection
… and the disease outcome in BALB/c mice. Early parasite replication and immunological events were studied in parallel through applying an in vivo imaging system (IVIS) with luciferase expressing T. gondii and a cytometric bead array to quantify key immunological mediators. The results confirmed …

Immunological control of toxoplasma gondii infection
Prevalent worldwide, the protozoan parasite, Toxoplasma gondii, is an important cause of spontaneous abortion, ocular disease, mental retardation and encephalitis. Currently there are no human vaccines available. The first major aim of this study was to test potential HLA restricted peptide …

Phosphorus-31 NMR Spectroscopy of Parasitic Protozoa
… 31P NMR spectra of acid extracts of these parasites were high levels of pyrophosphate, and in most cases similarly high levels of the condensed inorganic phosphates: tri-, tetra- and pentapolyphosphate. Spectra were obtained at high resolution and complete resonance assignments have been …

The role of the P2X7 receptor in the intestinal inflammatory response to the parasite, Toxoplasma gondii
… gondii is an obligate intracellular protozoan parasite belonging to the phylum Apicomp lexa. It is found throughout the world, infecting a variety of warmblooded animals; overall it infects one in three people worldwide, though local prevalence rates vary widely. Experimental oral infection of …

Characterisation of Host- Parasite- Microbiota Interactions that Drive Hatching in Trichuris Species
… Understanding hatching could lead to greater control in the lab in maintaining T. trichiura life cycles, allowing us to use alternate more accessible hosts to study the human whipworm. I hypothesised that hatching in Trichuris spp, which is centered around the polar plugs of the egg, occurs as …

Development of a model for the monitoring and evaluation of nutrition and nutrition-related programmes in South Africa
… health promotion through interventions such as parasite control and micronutrient supplementation. An evaluation component was never part of the design of the PSNP. However, in the beginning of 2000 the North West Province, and later in 2000, the National Department of Health, commissioned …

The anthelmintic effect of Bacillus thuringiensis Cry5B on Haemonchus contortus in sheep
… Haemonchus contortus, a highly pathogenic parasite, in sheep. Two experiments tested efficacy of Cry5B in sheep experimentally infected with H. contortus. In the first, a live genetically modified, asporogenous strain of B. thuringiensis expressing cytosolic Cry5B protein (BaCC) was …
