Materials methods For seven years, targeted work carried out study spread different types dirofilariae region. Blood from 3 498 breeds, ages, conditions keeping household use examined. larvae counted using Fuchs-Rosenthal camera. The type dirofilaria blood determined by histochemical method. antigen imaginal form D. detected chromatographic test system ImmunoRun Antigen Detection Kit Caninae Heartworm Biogal (Israel).
