Detecting Dirofilaria immitis: Current Practices and Novel Diagnostic Methods

Area of Science:

• Veterinary Parasitology
• Molecular Diagnostics
• Public Health

Background:

• Cardiopulmonary dirofilariasis, caused by Dirofilaria immitis, affects canines and humans globally.
• Accurate and early diagnosis is critical for effective disease management.
• Traditional methods like microscopy and serology have limitations.

Purpose of the Study:

• To review and analyze various diagnostic methods for Dirofilaria immitis.
• To evaluate the potential of advanced molecular techniques for improved diagnosis.
• To emphasize the need for continuous improvement in diagnostic tools.

Main Methods:

• Review of traditional diagnostic methods (microscopy, serology).
• Analysis of current molecular techniques (PCR, qPCR).
• Exploration of advanced methods: HRM-qPCR, LAMP, ddPCR, miRNA detection.

Main Results:

• Current routine diagnostics rely on Knott's test and serology.
• PCR and qPCR are prevalent in research but not yet routine.
• Advanced techniques show potential for enhanced sensitivity and early detection.

Conclusions:

• Continuous improvement and adaptation of diagnostic tools are essential.
• Integrating advanced molecular methods into routine practice can improve detection rates.
• Enhanced diagnostic capabilities will lead to better outcomes for infected animals.
