摘要:
Disclosed are nucleic acid molecules from the genome of Dirofilaria spp. nematodes that contain single nucleotide polymorphisms related to reduced responsiveness of the nematodes to macrocyclic lactones. In one example, the species of Dirofilaria is Dirofilaria immitis (the agent of heartworm in animals). Also disclosed are methods for determining the responsiveness of Dirofilaria spp. nematodes to macrocyclic lactones, methods for selecting a treatment to treat an animal infected with a Dirofilaria spp. nematode, and kits for determining the responsiveness of Dirofilaria spp. nematodes to macrocyclic lactones.

摘要:
The present invention relates to the use of avermectin derivative as a drug for the treatment of parasitic infections. The avermectin derivative is represented by the formula (I) wherein: (i) R1 is chosen from the group constituted of —CH(CH3)2, —CH(CH3)CH2CH3, or cyclohexyle, (ii) X represents —CH2CH2—, or —CH═CH—, (iii) R2 is chosen from the group constituted of or —OH group, (iv) R3 is OH or NOH, (v) represents a single bond when R3 is OH, or a double bond when R3 is NOH, as an inhibitor of a membrane-bound protein which transports exogenous compounds out of target cells.

The invention relates to a method for determining the responsiveness of a Dirofilaria spp. nematode to a macrocyclic lactone, by determining the genotype of the nematode at a position in a P-glycoprotein gene of the nematode corresponding to position 1 1, and optionally to position 618, in SEQ ID NO: 1, wherein the genotype GG at a position corresponding to position 1 1, or at positions corresponding to positions 1 1 and 618, in SEQ ID NO: 1 indicates that the nematode is likely resistant to the macrocyclic lactone. The invention also relates to methods for selecting a treatment to treat an animal infected with macrocyclic lactone resistant Dirofilaria spp nematode, and treating the animal; or for selecting a prophylactic to prevent an animal from becoming infected with a macrocyclic lactone resistant Dirofilaria spp nematode, and providing the prophylactic to the animal. The invention further relates to an isolated nucleic acid having at least 80% sequence identity to SEQ ID NO: 1.

摘要:
The present disclosure concerns the determination of the resistance or the susceptibility of a nematode to an imidazothiazole anti-helmintic based on the assessment of the presence of an indel in the Hco-acr-8 gene (or the Hco-acr-8 gene gene ortholog). The present disclosure also provides tools and commercial packages for making such assessment.
