Figure 1From: Morphometric analyses of canine blood microfilariae isolated by the Knott’s test enables Dirofilaria immitis and D. repens species-specific and Acanthocheilonema (syn. Dipetalonema) genus-specific diagnosisMean length (μm) of microfilariae determined after fixation with the modified Knott’s technique. Measurements were conducted for 377 dogs with confirmed filarial infections (histochemical staining and PCR in part of the cases); each indicator corresponds to a dog sample, for which 10 microfilariae were measured.Back to article page
