Researchers from the Waltham Centre for Pet Nutrition have published two studies which reveal, for the first time, the most common bacterial species associated with gum disease in cats.

Working with veterinary dentists and the Harvard affiliated Forsyth Institute, researchers used DNA sequencing technologies to identify 267 bacterial species present in feline dental plaque and build a database detailing the differences between bacterial populations in healthy cats and those in cats with gum disease.

Dr. Ian Davis, Oral Health Researcher at WALTHAM, part of Mars Petcare, said: "This knowledge is a first step in understanding the potential for improving oral health of cats through dietary interventions that target disease-associated bacteria."

The studies also revealed that the bacterial species in feline plaque were more similar to those observed in canine plaque than to those found in humans. This suggests that interventions targeted at bacteria which cause oral disease in humans are unlikely to be effective in cats, and there is more potential to learn from interventions that work well in dogs.

Dr. Davis added: "It’s important for pet owners to know that cats are just as susceptible to gum disease as dogs and understand the importance of maintaining a good oral hygiene routine; ideally including tooth brushing and dental treats or a specific dental diet".  

The first study was published in Veterinary Microbiology in February 2015. The second was published on 25th November in PLOS ONE, and can be downloaded here: http://dx.plos.org/10.1371/journal.pone.0136986.
