Using molecular tools for diagnosis in veterinary parasitology

Area of Science:

• Veterinary Parasitology
• Molecular Diagnostics
• Animal Health

Background:

• Molecular biology advancements offer precise tools for identifying veterinary parasites.
• Polymerase chain reaction (PCR) is a key molecular technique utilized in this field.
• Ribosomal DNA/RNA and random amplified polymorphic DNA (RAPD) are common targets for parasite identification.

Purpose of the Study:

• To review the application of molecular tools in veterinary parasitology.
• To highlight the most studied protozoan and helminth genera using these methods.
• To assess the current diagnostic utility of molecular techniques in veterinary practice.

Main Methods:

• Utilizing polymerase chain reaction (PCR) for parasite identification.
• Analyzing ribosomal DNA and RNA sequences as molecular targets.
• Employing random amplified polymorphic DNA (RAPD) for genetic profiling.
• Focusing on genera such as Eimeria, Babesia, Theileria, Trypanosoma, Cryptosporidium, Trichinella, and Trichostrongylids.

Main Results:

• PCR is the predominant molecular tool for parasite identification in veterinary research.
• Eimeria, Babesia, Theileria, Trypanosoma, and Cryptosporidium are frequently studied protozoa.
• Trichinella species and ruminant Trichostrongylids are the most investigated helminths.
• Molecular identification remains primarily a research methodology.

Conclusions:

• Molecular tools significantly advance the identification of veterinary parasites.
• Despite their potential, these methods are not yet standard for field diagnostics.
• Further integration is needed to translate research techniques into practical veterinary diagnostics.
