Sequential breast implant infections due to Campylobacter fetus subsp. fetus.

Campylobacter jejuni and Campylobacter coli are the leading causes of bacterial intestinal infections worldwide, while Campylobacter fetus subsp. fetus (C. fetus) has been reported to cause extraintestinal infections, including medical device implant infections. However, breast implant infections have rarely been reported. We describe the case of a 64-year-old woman with breast implant infection and vertebral osteomyelitis due to C. fetus. The patient recovered by surgical removal of the infected left implant and was treated with antibiotics for 6 weeks. However, two weeks after the completion of antibiotics, she experienced an infection in the right implant due to C. fetus , which had developed quinolone resistance with a G91T mutation during the treatment course. This case showed that C. fetus can cause breast implant infections, and although the infection may appear to be unilateral initially, the possibility of sequential contralateral infection should be considered.
