Very limited data exists on the genetic diversity of Toxoplasma gondii from Eastern Europe. We present the first Romanian case of symptomatic congenital toxoplasmosis in which the T. gondii strain was isolated after inoculation in mice of a cerebrospinal fluid sample from a living neonate. The T. gondii strain was genotyped with 15 microsatellite markers distributed on 10 of the 14 chromosomes of T. gondii. The strain had a type II genotype.

Objectives: Toxoplasmosis is a zoonotic parasitic disease caused by (), which can lead to complications such as encephalitis and ocular toxoplasmosis. The disease becomes more severe when the host's immune system is compromised. Rhoptry proteins are major virulence factors that enable to invade host cells.

Pathogenesis of Toxoplasma gondii in the intermediate host is based on the tachyzoite ability to divide rapidly to produce significant amount of daughter cells in a reduce time frame. The regulation of the cell-cycle specific expression program is therefore key to their proliferation. Transcriptional regulation has a crucial role in establishing this expression program and transcription factors regulates many aspects of tachyzoite cell cycle.

is a protozoan, and the etiologic agent of toxoplasmosis, a disease that causes high mortality in immunocompromised individuals and newborns. Despite the medical importance of toxoplasmosis, few drugs, which are associated with side effects and parasite resistance, are available for its treatment. Here, we show a screening of molecules present in COVID-Box to discover new hits with anti- activity.

is a widespread foodborne parasite that affects both humans and animals worldwide. The genetic characterization of this parasite has become crucial due to its epidemiological and clinical implications. The present study focused on the direct genetic characterization of -positive DNA samples from Northern Italy, using three standardized genotyping methods.

The protozoan Toxoplasma gondii is a ubiquitous and highly prevalent parasite that can theoretically infect all warm-blooded vertebrates. In humans, toxoplasmosis causes infections in both immunodeficient and immunocompetent patients, congenital toxoplasmosis, and ocular lesions. These manifestations have different degrees of severity.
