We were gifted a dog. he had ticks and parents called vet and removed them. as the dog runs everywhere what kind of bacterias and infections can he transmit to me?

Yes, pets have germs: Bacterial infections that a person can get from his pet include campylobacter and salmonella (both bacteria cause fever and diarrhea), cat scratch disease, etc... A variety of viral diseases, and parasites, can also be passed from pets to humans. One's veterinarian surely has brochures or a website talking about how to keep both the dog and the human healthy.
