The bacteria that cause this condition house themselves in an area of the digestive system known as the duodenum. The feces of an infected animal carry the bacteria. Accidental or inadvertent contact with the feces of an infected animal poses a potential threat to people. Upon contact with the hands, the bacteria can enter the body. Pet owners should pay special attention to washing their hands after cleaning up pet feces.
The animals most likely to be infected by this bacterium are cats, dogs, and ferrets. Both the pets and their owners will experience episodes of intermittent vomiting. Humans also show symptoms such as nausea, weight loss, and a diminished appetite. Pets and owners will need antibiotic treatment to get rid of the infection. Owners can also make use of antacids to ease the pain caused by their stomach ulcers.
