Objective Dirofilariasis or heartworm disease, a mosquito-borne parasitic disease,
continues to be a serious problem in canine (dogs) and feline (cats) species.
The disease is caused mainly by the filarial nematode, Dirofilaria immitis. In
canine dirofilariasis, the adult worms, present in the pulmonary arteries and
the right ventricle, causing damages and leading to pulmonary hypertension
and right-sided congestive heart failure. In addition, acute death in feline
dirofilariasis causes lung injury resulting in respiratory distress. Being critical
to transmission and complex disease pathology, the microfilarial stage is
useful in laboratory diagnosis; however, the microfilaria identification process
is laborious, difficult and time-consuming. Development of a molecular
diagnostic will provide an efficient alternative. The present study analyzes
relative efficiencies of three different methods of DNA extraction from D.
immitis microfilariae for quantitative real-time PCR (qPCR).
