Evolution of Toxoplasma gondii Detection and Genotyping Methods.

Area of Science:

• Parasitology
• Molecular Biology
• Public Health

Background:

• Toxoplasma gondii is a widespread protozoan parasite affecting approximately 30% of humans.
• Infections pose significant risks to pregnant women, the elderly, and immunocompromised individuals.
• Accurate detection and genotyping are vital for public health surveillance and understanding parasite diversity.

Purpose of the Study:

• To review and present methods for detecting and genotyping Toxoplasma gondii.
• To discuss the applications, advantages, and limitations of various diagnostic techniques.
• To highlight recent advancements in molecular detection and genotyping.

Main Methods:

• Discussion of established PCR techniques (one-step, nested PCR).
• Inclusion of newer molecular methods like LAMP and ddPCR for detection.
• Overview of genotyping methods including PCR-RFLP, MLST, and microsatellite analysis.

Main Results:

• Comprehensive overview of available Toxoplasma gondii detection methods.
• Detailed comparison of molecular techniques for parasite identification.
• Presentation of common genotyping strategies for parasite characterization.

Conclusions:

• Molecular methods are increasingly important for Toxoplasma gondii detection and genotyping.
• Understanding parasite diversity aids in investigating its circulation and virulence.
• This review provides a valuable resource for researchers and diagnosticians in the field.
