Development of a PCR-Enzyme Immunoassay Oligoprobe Detection Method for Toxoplasma gondii Oocysts, Incorporating PCR Controls

Detection of Toxoplasma gondii oocysts in water sample concentrates by real-time PCR.

PCR techniques in combination with conventional parasite concentration procedures have potential for the sensitive and specific detection of Toxoplasma gondii oocysts in water. Three real-time PCR assays based on the B1 gene and a 529-bp repetitive element were analyzed for the detection of T. gondii tachyzoites and oocysts. Lower sensitivity and specificity were obtained with the B1 gene-based...

Real-time PCR for quantitative detection of Toxoplasma gondii.

The protozoan Toxoplasma gondii is one of the most common infectious pathogenic parasites and can cause severe medical complications in infants and immunocompromised individuals. We report here the development of a real-time PCR-based assay for the detection of T. gondii. Oligonucleotide primers and a fluorescence-labeled TaqMan probe were designed to amplify the T. gondii B1 gene. After 40 PCR...

Detection of Toxoplasma gondii oocysts in soils in Northwestern China using a new semi-nested PCR assay

BACKGROUND Toxoplasma gondii is a zoonotic pathogen that can infect a range of animals and humans. Ingestion of T. gondii oocysts in soil is a significant transmission route for humans and animals acquiring toxoplasmosis. In the present study, we developed a new semi-nested PCR method to determine T. gondii oocysts distribution in soils in northwestern China. RESULTS The one tube semi-nested ...

Prevalence of Toxoplasma gondii oocysts through Copro-PCR in cats at Pet Center (UVAS), Lahore, Pakistan.

Toxoplasmosis is a major zoonotic disease of warm-blooded animals caused by Toxoplasma gondii. Cats are the only definitive host and they excrete environmentally resistant T. gondii oocysts in their faeces. Coproscopy was used to detect oocysts of enteric coccidians and then Copro-PCR was employed to test specifically for T. gondii in 470 cat samples. The prevalence of T. gondii oocysts was 2.3...
