First Hungarian case of an infection caused by multidrug-resistant Bacteroides fragilis strain

• Multidrug resistant Bacteroides sp. is rare clinical pathogen worldwide.
• We presented a case report of MDR Bacteroides fragilis strain.
• The presence of cfiA-IS1187 and the presence of nimA-IS1168 on a 11 kb plasmid are infrequent.

We report a case caused by a multidrug-resistant (MDR) Bacteroides fragilis strain isolated from abdominal fluid of a male patient with complex underlying diseases. The patient had received antibiotics prior to the presented case. As far as we know, this case with a MDR B. fragilis is the first from Hungary, and Eastern-Europe, as well.
