ToxoDB (http://ToxoDB.org) is a genome and functional genomic database for the protozoan parasite Toxoplasma gondii. It incorporates the sequence and annotation of the T. gondii ME49 strain, as well as genome sequences for the GT1, VEG and RH (Chr Ia, Chr Ib) strains. Sequence information is integrated with various other genomic-scale data, including community annotation, ESTs, gene expression ...
چکیده توکسوپلاسموز، بیماری است که توسط انگل توکسوپلاسما گوندئی ایجاد می شود. گربه سانان مخصوصا گربه های اهلی، مهم ترین مخزن این تک یاخته برای انسان و دیگر حیوانات به شمار می روند. توکسوپلاسما گوندئی تنوع ژنتیکی بالایی دارد. هدف از انجام این مطالعه، بررسی پاسخ سرولوژیک گربه ها به سویه me49 توکسوپلاسما گوندئی و ارزیابی ارزش تشخیصی روش الایزا با استفاده از آنتی ژن sag1 در تشخیص عفونت ناشی از این ...
The possibility of horizontal transmission of T. gondii was examined in squirrel monkeys. After three monkeys were inoculated perorally with 1.1-2.1 x 10(3) cysts of the T. gondii ME49, the animals were divided into two cages and maintained with one normal monkey for each cage as a cagemate. Two out of the three T. gondii-inoculated monkeys died, and the remaining one monkey was sacrificed in a...
AIM To determine the usefulness of prednisolone in increasing the number of Toxoplasma (T.) gondii tachyzoites and bradyzoites in mice. MATERIALS AND METHODS The mice were water-fasted prior to being immunosuppressed with oral inoculation of prednisolone. Tachyzoites of 7T gondii RH strain were inoculated into mice and the number of the parasites in the intraperitoneal fluids was then determi...
UNLABELLED During infections with the protozoan parasite Toxoplasma gondii, gamma-aminobutyric acid (GABA) is utilized as a carbon source for parasite metabolism and also to facilitate parasite dissemination by stimulating dendritic-cell motility. The best-recognized function for GABA, however, is its role in the nervous system as an inhibitory neurotransmitter that regulates the flow and timin...
Immunization with DNA can induce humoral and cell-mediated immune responses, both of which are important in conferring immunity to Toxoplasma gondii. The efficacy of genetic vaccination with a cDNA encoding the T. gondii SAG1 (P30) surface antigen was evaluated. Sera of immunized mice showed recognition of T. gondii tachyzoites by immunofluorescence and exhibited high titers of antibody to SAG1...
A novel Toxoplasma gondii interspersed repeat element (TgIRE), present in most of the tachyzoite chromosomes, was characterised. Two regions on the TgIRE sequence showed high identity to two different T. gondii expressed sequence tag cDNAs of unknown function, which seems to be TgIRE pseudogenes. Two set of primers were designed, 2-2' and 2-3, that amplify products of 1.02 and 0.62 kb, respecti...
