Toxoplasma gondii LCAT Primarily Contributes to Tachyzoite Egress
Egress is a crucial phase of the Toxoplasma gondii intracellular lytic cycle. This is a process that drives inflammation and is strongly associated with the pathogenesis observed during toxoplasmosis. Despite the link between this process and virulence, little is known about egress on a mechanistic or descriptive level. Previously published work has suggested that a phospholipase, lecithin-chol...
متن کاملShear Forces Enhance Toxoplasma gondii Tachyzoite Motility on Vascular Endothelium
Toxoplasma gondii is a highly successful parasite that infects approximately one-third of the human population and can cause fatal disease in immunocompromised individuals. Systemic parasite dissemination to organs such as the brain and eye is critical to pathogenesis. T. gondii can disseminate via the circulation, and both intracellular and extracellular modes of transport have been proposed. ...
متن کاملTachyzoite-induced life cycle of Toxoplasma gondii in cats.
The tachyzoite-induced cycle of Toxoplasma gondii was studied in 46 cats. Tachyzoites of the M-7741 or Me-49 strain of T. gondii were administered orally to cats by pouring into the mouth or by stomach tube, or by intraintestinal inoculation. Ten weaned cats that had been inoculated with tachyzoites directly in the intestine were killed 1, 3, 6, 9, 12, 15, 18, or 25 days later, and their tissue...
متن کاملToxoplasma gondii Soluble Tachyzoite Antigen Triggers Protective Mechanisms against Fatal Intestinal Pathology in Oral Infection of C57BL/6 Mice
Toxoplasma gondii induces a potent IL-12 response early in infection that results in IFN-γ-dependent control of parasite growth. It was previously shown that T. gondii soluble tachyzoite antigen (STAg) injected 48 hr before intraperitoneal infection reduces lipoxin A4 and 5-lipoxygenase (5-LO)-dependent systemic IL-12 and IFN-γ production as well as hepatic immunopathology. This study investiga...
متن کاملNeurotropic Parasite Toxoplasma gondii and Immunosuppressed Patients
Toxoplasmosis is an anthropozoonosis caused by the protozoan Toxoplasma gondii, an obligate intracellular parasite belonging to the phylum Apicomplexa. It presents a cosmopolitan geographic distribution, with high rates of infection in humans; capable of infecting nucleated cells from a wide variety of hosts. Toxoplasmosis is one of the most common opportunistic infections affecting HIV positiv...
