Salmonella Infections—Infectious Arthritis

Also called: Septic arthritis

Most kinds of arthritis cause pain and swelling in your joints. Joints are places where two bones meet, such as your elbow or knee. Infectious arthritis is an infection in the joint. The infection comes from a bacterial, viral, or fungal infection that spreads from another part of the body. Symptoms of infectious arthritis include

• Intense pain in the joint
• Joint redness and swelling
• Chills and fever
• Inability to move the area with the infected joint

One type of infectious arthritis is reactive arthritis. The reaction is to an infection somewhere else in your body. The joint is usually the knee, ankle, or toe. Sometimes, reactive arthritis is set off by an infection in the bladder, or in the urethra, which carries urine out of the body. In women, an infection in the vagina can cause the reaction. For both men and women, it can start with bacteria passed on during sex. Another form of reactive arthritis starts with eating food or handling something that has bacteria on it.

To diagnose infectious arthritis, your health care provider may do tests of your blood, urine, and joint fluid. Treatment includes medicines and sometimes surgery.

Salmonella is the name of a group of bacteria. In the United States, it is a common cause of foodborne illness. Salmonella occurs in raw poultry, eggs, beef, and sometimes on unwashed fruit and vegetables. You also can get infected after handling pets, especially reptiles like snakes, turtles, and lizards.

Symptoms include

• Fever
• Diarrhea
• Abdominal cramps
• Headache
• Possible nausea, vomiting, and loss of appetite

Symptoms usually last 4-7 days. Your health care provider diagnoses the infection with a stool test. Most people get better without treatment. Infection can be more serious in the elderly, infants, and people with chronic health problems. If Salmonella gets into the bloodstream, it can be serious. The usual treatment is antibiotics.

Typhoid fever, a more serious disease caused by Salmonella, is not common in the United States. It frequently occurs in developing countries.
