A bacterial infection that can cause several problems in dogs has been transmitted to humans, not once, but three times. Is this something we should be worried about?

So what is brucella canis and is it a potential threat to humans?

What is brucella canis?

As mentioned above, brucella canis is a bacterial infection that typically affects dogs. It causes premature ageing, back pain, and infertility and can cause your pet to become lethargic.

This infection is not life-threatening to dogs, but it is incurable and, as reported by The Independent, the only way to control transmissions is to euthanasine those infected. The number of cases of dogs has gone from 9 in 2020 to 91 in 2023 so far.

The Human Animal Infections and Risk Surveillance (HAIRS) released a report on Monday, September, 18; they explained that even though brucella canis is considered ‘low risk in the UK’ they still advise dog breeders and charities to routinely test the dogs they have imported into the country.

The cases of brucella canis in humans

According to The Independent, it is believed that the first reported of brucella canis in humans is Wendy Hayes, from Stoke-on-Trent in 2022. She contracted the bacterial infection from her rescue Moosha’s birthing fluids. She was sadly forced to put down all five of her dogs.

Wendi Shepherd, Head of Emerging Infections and Zoonoses at UKHSA, said:

We have seen a small number of cases of Brucella canis in people in the UK this year. However, the risk to the general public in the UK is very low and the risk to people who have had close contact with an infected dog is low.

Adding:

From the small number of cases of the infection that have been reported in humans worldwide, the infection is usually mild, but people who have weakened immune systems, are pregnant, or are young children may be more likely to experience more serious infection
