Multiple drug resistance in the canine hookworm Ancylostoma caninum : an emerging threat? Parasit Vectors. 2019 12(1):576. Jimenez Castro PD, Howell SB, Schaefer JJ, et al.And as the researchers explain, “the scale-up of mass drug administration for soil-transmitted helminths is now placing similar selection pressures for benzimidazole resistance on human hookworms and reduced efficacies are widely reported.” They offer that the deep amplicon sequencing assay from the study could be used to monitor worldwide benzimidazole resistance in human hookworms. Captain Hook can infest dogs in almost all of the same ways a dog or puppy can acquire roundworms: prenatal infections through the migration of worms through. caninum is phylogenetically similar to the hookworm species of humans ( A. The eggs and larvae are found in the dirt where. The eggs are passed in your pets stool and hatch into larvae. The study notes that if anthelmintic resistance can arise in canine hookworms, human medicine should take notice because A. You wont get it from petting your dog or cat. caninum, strongly suggesting that this is an emerging problem in the United States.” They go on to describe the findings as “important and concerning,” as the rise and spread of canine hookworms that are resistant to the three main anthelmintic classes-the only effective drug classes currently approved for the treatment of canine hookworms in the U.S.-could seriously threaten canine health.īut according to the researchers, dogs aren’t the only animals in danger. Moreover, a high frequency of resistance-associated single nucleotide polymorphisms was identified at codon 167 in the three resistant isolates.Īccording to the researchers, this study’s findings “conclusively demonstrate multiple anthelmintic resistance in multiple independent isolates of A. As for the two isolates treated with pyrantel, one of the egg counts had no change and the other actually increased. caninum isolates taken from the three dogs with suspected drug resistance had resistance ratios ranging from 6 to more than 100 for the egg hatch assay and from 5.5 to 69.8 for the larval development assay. When compared with the dogs with no history of anthelmintic treatments, the A. Finally, using DNA extracted from pools of eggs, third-stage larvae or adults, the researchers used deep amplicon sequencing assays to measure the frequency of nonsynonymous single nucleotide polymorphisms at three different codons (167, 198 and 200) of the A. ![]() To detect pyrantel resistance, three of the infected research dogs (representing two isolates) were treated with the anthelmintic drug and then fecal egg count reductions were measured. These assays were also conducted on eggs taken from the laboratory-infected research dogs. Hookworm eggs from these samples were used to infect laboratory beagles and to perform egg hatch assays (to detect resistance to benzimidazoles) and larval development assays (to detect resistance to macrocyclic lactones). Castro and his team obtained fecal samples from three dogs (a greyhound, a miniature schnauzer and a hound mix) being treated for persistent hookworm infections, as well as from two infected dogs with no history of treatment with anthelmintics. Jimenez Castro, DVM, from the University of Georgia College of Veterinary Medicine, set out to study the validity of this hunch. Most dogs (and cats) will acquire hookworm larvae by ingesting them during routine grooming of their fur, however, hookworms are also known to penetrate. ![]() veterinary colleges have reported an uptick in infection recurrence within the past three years-mostly in greyhounds, but in other breeds as well-which suggests the parasite may have become resistant to the drugs typically used to control it. However, parasitologists from several U.S. You may not notice this.Although it’s the most prevalent intestinal nematode parasite in dogs in the United States, Ancylostoma caninum (canine hookworm) has historically been well controlled with the anthelmintic drugs febantel, moxidectin, milbemycin oxime, fenbendazole and pyrantel. The people you live with may also need to be treated.Īny worms in your gut will eventually pass out in your poo. If you have worms, a GP will prescribe medicine to kill them. You might be asked to provide a sample of poo so it can be tested for worm eggs. ![]() It does not matter which type of worm you have – all worm infections are treated in a similar way.
