[Congenital toxoplasmosis with hydrocephalus diagnosed in utero: outcome of treatment].

Background: The neurological outcome for severe toxoplasmosis can be poor despite appropriate management.

Case Report: A maternal toxoplasma infection occurred at 16 weeks of amenorrhoea; prenatal diagnosis was attempted at 20 weeks, fetal infection was confirmed by mouse inoculation at the 30th week. Pyrimethamine plus sulfadiazine treatment was initiated.

[Cryopreservation of isolates of Toxoplasma gondii in cell culture].

For a better preservation and identification of Toxoplasma gondii isolates, we propose a new method of freezing of toxoplasma growth in THP-1 cell culture. A cystogenic strain isolated from foetal blood has been grown in these cells and frozen in liquid nitrogen. After thawing, toxoplasma recover the same growth rate and morphology in vitro and the same capacity to form brain cysts into mice compared to the initial strains.

Characterization of AGT1 encoding a general alpha-glucoside transporter from Saccharomyces.

Molecular genetic analysis is used to characterize the AGT1 gene encoding an alpha-glucoside transporter. AGT1 is found in many Saccharomyces cerevisiae laboratory strains and maps to a naturally occurring, partially functional allele of the MAL1 locus. Agt1p is a highly hydrophobic, postulated integral membrane protein.
