Answer

Molecular diagnostic methods of diagnosing toxoplasmosis include techniques such as conventional polymerase chain reaction (PCR), nested PCR, and real-time PCR for detection of T gondii DNA in clinical samples. The original protocol for molecular detection of T gondii using con­ventional PCR targeted the B1 gene. Studies have also described detection of T gondii based on amplification of ITS-1 and 18S rDNA fragments, a method whose sensitiv­ity was similar to the B1 gene.
