Veterinary vaccines against Toxoplasma gondii.
Toxoplasma gondii has a very wide intermediate host range and is thought to be able to infect all warm blooded animals. The parasite causes a spectrum of different diseases and clinical symptoms within the intermediate hosts and following infection most animals develop adaptive humoral and cell-mediated immune responses. The development of protective immunity to T. gondii following natural infe...
متن کاملVaccines against Toxoplasma gondii: challenges and opportunities.
Development of vaccines against Toxoplasma gondii infection in humans is of high priority, given the high burden of disease in some areas of the world like South America, and the lack of effective drugs with few adverse effects. Rodent models have been used in research on vaccines against T. gondii over the past decades. However, regardless of the vaccine construct, the vaccines have not been a...
متن کاملAdjuvanted multi-epitope vaccines protect HLA-A*11:01 transgenic mice against Toxoplasma gondii.
We created and tested multi-epitope DNA or protein vaccines with TLR4 ligand emulsion adjuvant (gluco glucopyranosyl lipid adjuvant in a stable emulsion [GLA-SE]) for their ability to protect against Toxoplasma gondii in HLA transgenic mice. Our constructs each included 5 of our best down-selected CD8+ T cell-eliciting epitopes, a universal CD4+ helper T lymphocyte epitope (PADRE), and a secret...
متن کاملRecombinant scFv Antibodies against P30 Surface Protein of Toxoplasma Gondii
Background & Aims: Toxoplasma gondii is an obligate, intracellular parasite, which is widely spread in the world. The parasite is able to infect all warm-blooded hosts including humans and farm animals. The infection in humans often occurs after the ingestion of raw or undercooked meat containing tissue cysts. Several methods have been applied to detect this parasite in contaminated foods. Reco...
متن کاملCellular defenses against Toxoplasma gondii in newborns.
Mononuclear phagocytes, particularly macrophages (M phi) that have been activated by lymphokines, are the principal defense against intracellular pathogens such as Toxoplasma gondii. To determine reasons for the newborns' susceptibility to Toxoplasma infection, we compared: the interaction of Toxoplasma with newborns' mononuclear phagocytes (blood monocytes and two types of newborn M phi, those...
