How much bacteria is found in a dog's mouth? |

Species Comparisons
It is important to note that when you conduct species comparisons that you understand the differences between the species. While dogs and humans both have bacteria in their mouths, each bacteria is species specific.
Test bacteria on any surface with the Surface Microbes Science Fair Projects Kit: after hand sanitizer, hands, disinfectant.. for example. You can use antibiotics to test the bacteria too.
Anytime you want to test how many bacteria are On Top of a surface like a desk, skin, chicken, computer keyboard, bread dough, a hard piece of chocolate, cheese, inside of an animal's cheek, etc. then use the surface experimenter kit. The kit will let you calculate how many bacteria there are per unit surface area on the object. You can also test for e-coli, however, only the microbe water kit will let you distinguish e. coli from other coliforms and bacteria.
My objective is to see if dogs have cleaner mouths than humans. My gaol will be trying to prove that dogs have cleaner mouths than humans.

The high in my experiment to see who had the most bacteria on nutrient agar was human 2 with an average of 73.25 and the low in my experiment was human 1 at 4.5. The high in my experiment to see who had the most bacteria on the Blood agar plates was dog 6 at 52.0 and the low was dog 2 and dog 3 at 16.75. The high in my experiment to see who had the most pathogens was human 2 at 25.66 and the low was dog 3 at 8.37. The high in all my averages on nutrient agar plates was dogs at 35.25and the low was humans at 28.79. The high in all my averages on Blood agar plates was humans at 28.83 and the low in was dogs 27.08. The high in all my averages for Alpha and Beta Hemolysis was humans at 17.82 and the low was 14.32.
After concluding my investigation to see if dogs have cleaner mouths than humans I found that my hypothesis, that dogs would have cleaner mouth than humans was incorrect. My results were inconclusive. Reason being statistics have shown no real difference between the two groups, humans and dogs were equivalent. 3rd party contributor
