CHILDREN may love being smothered in doggy kisses, but canine stomach infections can be transmitted to humans via licks on the face, according to a report in the Lancet. It describes the case of a 12-year-old girl who complained of abdominal pain, nausea and vomiting, and whose dog suffered similar symptoms. Both pet and owner were found to be carrying gastrospirillum hominus, the bacteria that causes gastritis, or inflammation of the stomach lining. Both responded well to antibiotics.
