INFECTION OF THE THYROID GLAND CAUSED BY CAMPYLOBACTER FETUS SUBSP. FETUS

What is it about?

We report what we consider to be the first case of an abscess of the thyroid gland due to Campylobacter fetus subsp. fetus (C. fetus) in a patient suffering from hyperthyroidism. C. fetus is known as a rare and opportunistic pathogen in humans, causing a broad variety of systemic infections. Acquisition by humans is thought to occur through contact with animals or animal products and to start as a gastro-intestinal colonization.

Why is it important?

The detection of C. fetus in stool is challenging, since culture efforts are generally directed in order to fulfil growth requirements of C. jejuni, a much more common enteric pathogen. Detection of C. fetus in non-stool samples is even more challenging since routine culture doesn’t imply prolonged incubation (>72h), selective media and microaerophilic conditions. It is therefore not unlikely that human infections caused by C. fetus occur more often than generally assumed.
