Forest Lake, with the second-highest number of registered dogs in Brisbane, is facing a growing concern as a new study reveals widespread resistance to common deworming medication among hookworms.
A recent University of Queensland study, conducted in partnership with the University of Sydney, has found that 70% of hookworm samples across Australia show genetic mutations linked to resistance to benzimidazole-based dewormers.
These medications are one of the primary treatments for hookworm infections in dogs. This alarming discovery means that a common and effective treatment for these parasites might be losing its power, putting local dogs at risk.
The Dangers of Hookworms
Hookworms are nasty parasites that live in dogs’ intestines and feed on their blood. They can cause serious health problems like anaemia, diarrhoea, and weight loss. Puppies are particularly vulnerable, as a hookworm infection can be fatal. Worryingly, these parasites can also infect humans, causing a skin condition called cutaneous larva migrans (CLM), which leads to an itchy and uncomfortable rash.
Resistance on the Rise
Dr Swaid Abdullah, a veterinary expert from the University of Queensland, explained that the research team used advanced testing methods to examine hookworm samples from over 100 animals in Australia and New Zealand.
The results showed that resistance to benzimidazole dewormers was spreading, even affecting the northern hookworm, a species previously considered unaffected. Dr Abdullah stressed that the effectiveness of these drugs should be above 95%, but the study found it was falling below this level.
Overuse of Dewormers a Key Factor
Dr Abdullah believes that the widespread practice of “blind treatment” or deworming medication to dogs without testing for hookworms first is a major reason for the growing resistance. He compared it to the overuse of antibiotics, which has led to antibiotic resistance in many bacteria. Instead, he recommends a more targeted approach, similar to how doctors prescribe antibiotics only when necessary.
Protecting Your Pets and Family
The best way to protect your dog from hookworms is to have them tested twice a year and only treat them if they have an infection. Dr Abdullah also emphasised the importance of responsible pet ownership in preventing the spread of hookworms. Dog owners should always immediately pick up their faeces and dispose of them properly, even in their own yards. This simple action can help stop hookworms from infecting other dogs and humans.
