New research has uncovered a surprising link between some everyday health problems and a furry friend in the family home.
A Queensland study has found most people with gum disease also carry parasites in their mouths.

And for dog owners, the culprit may be a lot closer than expected.
Dr Simone Sleep, a dental researcher and biomedical scientist, made the discovery the hard way.
“I was not expecting a dog parasite to be running around in my mouth,” she told 7NEWS, describing it as “absolute shock, horror”.
A lifelong animal lover who grew up on a farm, Sleep had been battling fatigue, brain fog and gum issues for years before discovering the real cause.
“I don’t think people realise how sick it can make people.”
The microscopic culprit, Trichomonas tenax, is an oral parasite thriving in people with gum disease.
Once inside the body, it attacks white blood cells, weakens the immune system and may contribute to a range of chronic symptoms.
“You can actually see the trail of destruction they leave behind,” Sleep said.
“Bleeding gums is a dead giveaway. Also, if you’re struggling with iron levels.”
Worryingly, the parasite is contagious, and pet owners may unknowingly be exposed.
According to Sleep, the chain of events is simple: your dog goes to the toilet, licks itself, then gives you a kiss on the mouth.
That innocent show of affection could be exposing you to harmful oral parasites.
Worming your dog won’t protect you from this type of infection and regular dental check-ups probably won’t catch it either.
“It requires highly specialised training,” Sleep said.
She’s now raising awareness, particularly for pet owners who like to get up close and personal with their four-legged-friend.
Because while it might seem harmless, you could be looking for more than just love if you smooch your pooch.
“You don’t know what you’re swapping,” Sleep said.
So next time your pup goes in for a face lick, it might be worth offering a high five instead.
