The Oral Microbiome of Dogs and Humans

Each species, including dogs and humans, has its own oral microbiome, which refers to the collection of microorganisms present in the mouth. Humans have an oral microbiome consisting of approximately 400 to 500 bacterial species, while dogs have around 400 bacterial species in their oral microbiome. Dogs and humans share only about 15% of the oral microbiome, meaning that the majority of bacterial species found in each species’ mouth are distinct.

The oral microbiome plays a crucial role in maintaining oral health. It consists of various bacteria, fungi, and viruses that coexist in a delicate balance. While some microbes can be pathogenic and contribute to dental diseases, others are beneficial and help protect against harmful invaders.

Diversity in the Oral Microbiome

The oral microbiome is a highly diverse ecosystem. It is influenced by multiple factors, including genetics, diet, oral hygiene practices, and overall health. Each individual has a unique oral microbiome, shaped by these factors.

In humans, the oral microbiome is primarily composed of bacterial species, with the most common phyla being Firmicutes, Bacteroidetes, Actinobacteria, and Proteobacteria. These bacteria play essential roles in maintaining oral health, such as breaking down food particles, aiding in digestion, and regulating the pH balance in the mouth.

In dogs, the oral microbiome also consists predominantly of bacteria, with similar phyla to those found in humans. However, there are differences in the specific bacterial species present. For example, Fusobacteria and Spirochaetes are more abundant in dogs compared to humans. These species are adapted to the unique oral environment of dogs and perform specific functions necessary for their oral health.

It’s worth noting that the oral microbiome is not static and can change over time. Factors such as age, diet changes, and the use of antibiotics can alter the composition of the oral microbiome in both dogs and humans.

The Interaction Between Oral Microbiomes

While dogs and humans share some similarities in the composition of their oral microbiomes, the majority of bacterial species are unique to each species. This distinct microbial composition prevents most bacteria from dogs to colonize and cause infections in humans, and vice versa.

However, there are instances where bacteria found in a dog’s mouth can be transmitted to humans and cause infections. This typically occurs through bites, as certain bacteria can be present in a dog’s saliva. Capnocytophaga canimorsus and Pasteurella canis are examples of bacteria commonly found in dog mouths that have been associated with human infections.
