Selective and universal primers for trematode barcoding in freshwater snails.

Area of Science:

• Parasitology
• Molecular Biology
• Ecology

Background:

• Trematodes are significant pathogens with medical, veterinary, and environmental importance.
• Isolating trematodes from intermediate hosts and identifying early life stages morphologically is challenging.

Purpose of the Study:

• To develop a species barcoding system for trematodes using selective PCR amplification.
• To create a diagnostic tool for rapid and accurate trematode identification in mixed samples.

Main Methods:

• Development of specific oligonucleotide primers targeting the 18S ribosomal DNA (rDNA) gene.
• Application of PCR amplification for selective detection of trematodes in freshwater snail hosts.
• Utilizing high polymorphism between conserved areas for species classification.

Main Results:

• A universal primer set was developed for trematodes infecting various freshwater snail species in Israel.
• The trematode barcoding system provides rapid identification based on an 800 bp sequence.
• Accurate species classification is achieved due to significant genetic polymorphism.

Conclusions:

• Trematode barcoding offers a fast and accurate alternative to traditional morphological identification.
• This molecular tool is valuable for diagnosing trematode infections in ecological and public health contexts.
• The developed system facilitates the study of trematode diversity and transmission dynamics.
