Although the Korean isolate KI-1 of Toxoplasma gondii has been considered to be a virulent type I lineage because of its virulent clinical manifestations, its genotype is unclear. In the present study, genotyping of the KI-1 was performed by multilocus PCR-RFLP and microsatellite sequencing. For 9 genetic markers (c22-8, c29-2, L358, PK1, SAG2, SAG3, GRA6, BTUB, and Apico), the KI-1 and RH stra...
توکسوپلاسما گونده ای یک انگل داخل سلولی اجباری است که مسئول توکسوپلاسموزیس درانسان وحیوانات بوده ودارای انتشارجهانی است. sag3 یک آنتی ژن سطحی بزرگ انگل است که در اتصال وحمله به سلولهای میزبان نقش مهمی را ایفاء می نماید. آنتی ژن sag3 در مراحل مختلف سیکل زندگی انگل ازجمله تاکی زوییت ، برادی زوییت و اسپوروزوییت بیان می شود . در این مطالعه از ژن کامل سطحی3(sag3 ) وآنتی ژن سطحی اصلی یک (sag1) توکسوپ...
Cats are important in the epidemiology of Toxoplasma gondii infection because they are the only hosts that can excrete the environmentally-resistant oocysts. In the present study, prevalence of T. gondii was determined in serum, feces, and tissues of 170 unwanted cats from Colombia, South America. Antibodies to T. gondii were assayed by the modified agglutination test and found in 77 of 170 (45...

 The present study aimed to assess enzyme-linked immunosorbent assay (ELISA) and nested-polymerase chain reaction (n-PCR) methods based on B1 gene for the detection of Toxoplasma (T.) gondii in blood milk local Iraqi goats. SAG3 was also used identify genotyping T. goats aborted women Iraq. A total 240 (80 blood, 80 sera, milk) lactating 30 samples from were included this study. 17 (21.2%...
The prevalence of Toxoplasma gondii infection in birds has epidemiological significance because birds are indeed considered as a good indicator of environmental contamination by T. gondii oocysts. In this study, the prevalence of T. gondii in 313 house sparrows in Lanzhou, northwestern China was assayed by the modified agglutination test (MAT). Antibodies to T. gondii were positive in 39 (12.46...
The prevalence of Toxoplasma gondii in 86 street dogs from Sri Lanka was determined. Antibodies to T. gondii were assayed by the modified agglutination test (MAT) and found in 58 (67.4%) of 86 dogs with titers of 1:20 in eight, 1:40 in four, 1:80 in 10, 1:160 in 22, 1:320 in six, 1:640 in five, and 1:1280 or higher in three. Hearts, tongues, and brains (either separately or pooled) of 50 dogs w...
Toxoplasmosis has been recognized as parasitic zoonosis with the highest human incidence. The human infection by the parasite can lead to severe clinical manifestations in congenital toxoplasmosis and immunocompromised patients. Contamination occurs mainly by foodborne ways especially consumption of raw or undercooked meat. In contrast to other foodborne infections, toxoplasmosis is a chronic i...
BACKGROUND Toxoplasmosis, a worldwide zoonotic disease, is caused by Toxoplasma gondii. The distribution of genetic diversity of T. gondii in wild animals is of great importance to understand the transmission of the parasite in the environment. However, little is known about T. gondii prevalence in wild animals and birds in China. METHODS We conducted the genetic characterization of T. gondii...
