Quantification of different types of neutrophil extracellular traps (NETs) induced by Dirofilaria immitis stages. Canine polymorphonuclear neutrophils (PMN) (n = 3, 2 × 105) we exposed to microfilariae (MF; 50 larvae) and L3 (10 larvae) on poly-l-lysine pre-coated coverslips for 1 and 3 h. After fixation, immunofluorescence analysis was performed using Sytox Orange as DNA-marker along with anti-histone antibodies. The types of NETs (diffNETs, sprNETs, and aggNETs) were identified microscopically and counted.
