Hookworms, parasites that can harm dogs and humans, are developing resistance to treatments, sparking health concerns in The Gap and across Australia.
Growing Resistance in Canine Parasites
A study conducted by the University of Queensland in collaboration with the University of Sydney found that 70 per cent of hookworm samples tested in Australia showed genetic mutations linked to resistance against benzimidazole-based dewormers. These drugs, which were once highly effective, are now increasingly failing to treat canine hookworm infections, raising significant health concerns for pet owners and communities.
The study, which examined samples from over 100 dogs in Australia and New Zealand, discovered that even previously unaffected species, such as the northern hookworm, have developed resistance.
Researchers highlighted that hookworms, which live in a dog’s small intestine and feed on blood, can cause anaemia, diarrhoea, and malnutrition. In severe cases, particularly in puppies, these infections can be fatal.
The Gap’s High Pet Population at Risk
The Gap, a suburb with abundant green spaces and a reputation for pet-friendly living, faces heightened risks. With 2,085 registered dogs as of March 2024, The Gap’s parks and communal areas provide ideal conditions for the spread of hookworm infections among pets and potentially to humans.
Experts warned that hookworms can infect humans through skin contact, causing a condition known as cutaneous larva migrans (CLM). This condition, described by Dr Swaid Abdullah from the University of Queensland, causes intense itching, blistering, and a red, snake-like rash. The shared spaces in The Gap highlight the need for preventative measures to protect both pets and people.
Dr Abdullah explained that the overuse of deworming treatments without proper diagnosis contributes to the rising resistance, similar to how overprescription of antibiotics creates resistant bacteria. He called for targeted testing and treatments to address the issue effectively.
Protecting The Gap’s Pets and Community
Experts emphasised several measures to mitigate the hookworm threat in The Gap and similar communities:
- Conduct regular parasite testing for dogs, ideally twice a year.
- Use targeted treatments based on diagnostic results rather than relying on blanket deworming approaches.
- Maintain hygiene by promptly picking up and properly disposing of dog waste, both in public spaces and at home.
Dr Abdullah urged pet owners to remain proactive, as clean environments and responsible pet ownership are key to preventing the spread of hookworms. He highlighted that diligent waste disposal is critical in preventing the transmission of parasites in shared spaces like parks and yards.
